               IN THE UNITED STATES COURT OF APPEALS

COMMISSIONER, ALABAMA DEPARTMENT OF CORRECTIONS,

                                                           Respondent - Appellee.



                   Appeal from the United States District Court
                      for the Northern District of Alabama


                                (August 30, 2019)

Before TJOFLAT, WILSON, and BRANCH, Circuit Judges.

BRANCH, Circuit Judge:

      Mark Allen Jenkins, an Alabama prisoner sentenced to death for the 1989

murder of Tammy Ruth Hogeland, appeals the district court’s denial of his petition
for a writ of habeas corpus, 28 U.S.C. § 2254. Before us are Jenkins’s arguments

that he received ineffective assistance of counsel during the penalty phase of his

trial and that he is intellectually disabled and therefore ineligible for the death

penalty. After careful consideration, and with the benefit of oral argument, we

affirm the denial of Jenkins’s habeas petition on both grounds.

                                 I.     BACKGROUND

                            A.        The Crime and Arrest

       We summarize the following background narrative from opinions of the

Alabama Court of Criminal Appeals and our own review of the record. See Jenkins

v. State, 

, 1037–40 (Ala. Ct. Crim. App. 1992); Jenkins v. State,

, 119–20 (Ala. Ct. Crim. App. 2004). The events leading up to the

murder began the evening of April 17, 1989. Jenkins was at the home of his

acquaintance Christine Nicholas. He had met her several months earlier at the

Omelet Shoppe restaurant where she worked. Jenkins was very intoxicated and

tried to seduce her. When she resisted, Jenkins got “real mad” and asked her

several times what she would do if someone came up from behind her and grabbed

her.

       At around 1 a.m., Jenkins and Nicholas drove to the Riverchase Omelet

Shoppe. Jenkins went inside and talked with one of the waitresses, Frieda Vines.

The manager, Douglas Thrash, recognized Jenkins as a regular customer who knew


                                            2
all of the waitresses. Thrash overheard part of Jenkins’s conversation with Vines

and heard mention of the Omelet Shoppe location near the Birmingham Airport.

Jenkins and Nicholas then returned to Nicholas’s home. Around 2 a.m., Nicholas’s

mother asked Jenkins to leave. He did so, falling down some steps and ramming

his car into another vehicle in the process.

      Meanwhile, 23-year-old Tammy Hogeland was making her way to work at

the Omelet Shoppe. Her sister Wendy, along with Tammy’s young son, picked

Tammy up from her college classes and drove her to the Riverchase Omelet

Shoppe a little after 9:30 p.m. Sometime after 10:00, Tammy was sent to work at

the airport Omelet Shoppe on Tenth Avenue, since that location was unexpectedly

shorthanded. Tammy was wearing her watch, a necklace with the words “special

sister,” her class ring, and her diamond engagement ring. Tammy was working as a

cook that night and was wearing a blue apron, black pants, a white shirt, and white

shoes. She and Sarah Harris were the only employees working at the airport

Omelet Shoppe that night.

      At about 2 a.m. on April 18, Harris saw Jenkins—whom she did not know—

drive up in a red sports car. His arrival was memorable to Harris because the car

nearly jumped the curb and crashed through the restaurant’s glass wall. Jenkins got

out of the car and came into the restaurant, appearing to be intoxicated. He walked

over to Hogeland and began talking to her. Harris later saw Jenkins and Hogeland


                                           3
drive away together in the red sports car. That was the last time anyone who knew

Hogeland ever saw her. Hogeland left behind her cigarettes, lighter, purse, and

paycheck. She left without telling anyone, which she had never done before.

Although Harris saw them drive off, she could not later say whether Hogeland left

with Jenkins willingly or was instead abducted.

      At around 5 a.m. that morning, Bobby and Geraldine Coe had stopped to

buy gas at a Chevron station on I-59 northeast of Birmingham when they saw

Jenkins drive up in the red sports car. The Coes noticed a female who appeared to

be “passed out” in the front passenger seat, but they could not say whether she was

alive or dead. While Bobby Coe was pumping gas, Jenkins asked him for some

cigarettes and said, “Looks like it’s been a long night and it looks like it’s going to

be a long day.” Jenkins then said “God bless you” before asking directions to I-

459. Coe gave him directions and got back in his car. As Coe pulled out onto the

interstate, he saw Jenkins follow him in the red sports car. Coe then saw the car

flash its lights, slow down, and pull to the side of the road between mile markers

151 and 152.

      At 8 a.m., Wendy Hogeland learned that Tammy was not at the restaurant,

and their mother called the police. Meanwhile, Jenkins went to the home of Steve

Musser, who noticed that he was wearing the same clothes as the day before.

Jenkins told Musser that his car had been stolen the night before and asked him if


                                           4
he would say that he had been with him all night. Musser refused. Christine

Nicholas also saw Jenkins in a grocery store that morning. He was looking at a

newspaper, making a phone call, and attempting to sell his Buick. Nicholas loaned

him $4 for gas. At around 10 o’clock that morning, Jenkins sold his car to Michael

Brooks, a mechanic at a local Chevron station. Jenkins had explained that he

needed the money so he could visit his sick mother in California. Another

mechanic at the service station drove Jenkins to the Greyhound bus station later

that morning.

       Jenkins awoke the next day on the Greyhound bus in Houston and was

ejected from the bus because his fare was used up. He then hitchhiked from

Houston to Phoenix, then to San Diego and Los Angeles. Jenkins was first

identified as a suspect in Hogeland’s disappearance by Officer Mike Weems of the

Hoover Police Department on April 19. Weems ate dinner at the Riverchase

Omelet Shoppe just about every day and had talked with Hogeland just as often.

He also knew Jenkins from the restaurant. Weems learned of Hogeland’s

disappearance from the other waitresses. Remembering how Jenkins often talked to

Hogeland and passed her notes,1 he gave Jenkins’s name to the missing persons

investigator. The investigator also learned that a red Mazda RX-7 sports car, which

 The jury was not permitted to hear, and the record does not reveal, what exactly Jenkins had
said to Hogeland that made Officer Weems suspect him in her disappearance.
                                               5
had been reported stolen from the service station where Jenkins worked, had been

recovered on I-459.

      The afternoon of April 21, a truck driver who had happened to stop on I-59

near mile marker 151 discovered Hogeland’s body off the side of the road. She was

naked, wearing only a watch, and was so badly decomposed that the body had to

be identified by dental records. From the fractured hyoid bone, it was determined

that she was manually strangled to death. Also found at the scene were Hogeland’s

apron, shoes, bra, panties, pants, and hair net, as well as some beer cans, a Mazda

RX-7 owner’s manual, and other items later determined to have come from the red

Mazda. Her necklace and rings were never found.

      Alabama authorities issued a warrant for Jenkins’s arrest and also obtained a

federal fugitive warrant. An FBI agent arrested Jenkins on May 1 in front of his

uncle’s house in Wilmington, California. Jenkins’s uncle later gave the police three

bags of Jenkins’s personal effects. Fibers recovered from Hogeland’s body and

clothing matched those of the Mazda, and hairs matching Hogeland’s were found

in the Mazda. Similarly, fibers from Jenkins’s clothing placed him in the Mazda,

and fibers of his jeans were found on Hogeland’s apron. A bootprint near

Hogeland’s body matched a combat boot from among the belongings Jenkins’s

uncle gave to the police, and Jenkins’s roommate said the boots looked just like

those that Jenkins wore.


                                         6
      A business card like those that had been in the Mazda’s glove box,

belonging to an owner of the Mazda, was recovered from Jenkins’s wallet after his

arrest in California. Later, Jenkins’s cellmate in the Alabama jail reported that

Jenkins told him “he had done the crime” and was worried that the couple from the

gas station would identify him or that the police would find his fingerprint on a

beer can at the scene. A St. Clair County grand jury indicted Jenkins for capital

murder.

                         B.     The Trial and Sentencing

      Jenkins was represented at trial in 1991 by attorneys Douglas Scofield and

Stan Downey. Scofield, the lead attorney, had been practicing criminal defense in

Birmingham since 1984 but had never before tried a capital murder case. Jenkins’s

landlord and his grandmother had arranged the referral and representation before

the court appointed him. Scofield agreed to the appointment on the condition that a

St. Clair County lawyer also be appointed. That lawyer was Downey, who had

more experience than Scofield but whose capital experience was limited to one

case that had not gone to trial. The two attorneys had agreed that Downey would

be responsible for jury selection, but Scofield eventually took over during the voir

dire. Per their agreement, Scofield was responsible for the guilt-phase trial,

although Downey participated by interviewing Jenkins several times. Scofield also

met with Jenkins around a dozen times. Jenkins had told him about his background


                                          7
and childhood, including the fact that he had had a difficult childhood and had

lived on the streets since age 11.

      Throughout the weeklong trial, Scofield pursued an outright acquittal. In

particular, he challenged Harris’s identification of Jenkins as the man who drove

away with Hogeland, and he challenged the medical examiner’s opinions about the

time and cause of Hogeland’s death. In his closing argument, Scofield took a wide-

ranging approach to undermining the State’s wholly circumstantial case against

Jenkins. He attacked the State’s timeline of the crime, questioning whether Jenkins

in his intoxicated state would have had the time and the ability to leave Nicholas’s

house, steal the Mazda, and abduct and kill Hogeland. He reminded the jury of the

weakness of Harris’s identification of Jenkins and the Coes’ identification of the

woman in the car. He pointed out that no physical evidence definitively linked

Jenkins to the Mazda, to Hogeland’s body, or to her jewelry, which was never

recovered. And he argued that the evidence provided no plausible motive for

Jenkins to have kidnapped, robbed, or killed Hogeland. In sum, he urged the jury

to find reasonable doubt and acquit Jenkins. At the very least, he argued, they

should find that the State failed to prove Jenkins’s intent to rob and kidnap

Hogeland, which were necessary to convict Jenkins of capital murder. He further

argued that, if the jury thought Jenkins killed Hogeland as a crime of passion, they

could convict him only of manslaughter. The jury deliberated for three hours and


                                          8
fifteen minutes before convicting Jenkins of capital murder, Ala. Code § 13A-5-

40(a)(1) & (2), i.e., murder committed in the course of kidnapping and robbery.

      The penalty phase took place that same afternoon. A week before trial,

Scofield and Downey had discussed the penalty phase, and Scofield understood

that Downey would be responsible for handling the penalty phase. Nonetheless, the

witness who was present to testify on Jenkins’s behalf during the penalty phase

was better acquainted with Scofield, so Downey suggested that afternoon that

Scofield conduct the direct examination. Scofield urged Downey to interview the

witness quickly and prepare to examine him, and Downey did so.

      Downey handled the penalty presentation to the jury. The State did not

present any additional aggravation evidence, resting on the evidence presented

during the guilt phase. One witness, Lonnie Seal, testified on Jenkins’s behalf in

order, in Downey’s words, to “reveal another side of Mark Jenkins to you that you

don’t know anything about.” Seal had met Jenkins in Fontana, California, in 1988

when they both worked at the same garage. Seal and his wife became friends with

Jenkins, and he visited in their home. When the Seals decided to move to Alabama

a few months later, Jenkins agreed to help with their move and to live with the

Seals in Alabama for a time. It took Lonnie Seal several weeks to find a job, but

Jenkins found a job in two days and contributed toward the family’s rent and




                                          9
groceries. Jenkins continued to visit the Seals after he moved into his own home,

and he would always bring a small gift for and play with the Seals’ infant son.

       Downey’s closing argument to the jury requested a sentence of life without

parole. Downey reminded the jurors that they had agreed during voir dire that

death was not always the appropriate punishment for homicide. Quoting the Bible,2

he reminded the jury that the Old Testament permitted capital punishment only

when supported by the testimony of two or three eyewitnesses, whereas in this case

there had been only circumstantial evidence. He asserted from Seal’s testimony

that “Mark had a side of him that was generous, that was giving, and that was

kind,” and argued that the deterrent and retributive purposes of capital punishment

would not be served in this case.

       The jury deliberated for 50 minutes before returning its nonbinding

recommendation of death by a vote of 10 to 2. See Ala. Code § 13A-5-46(e) (1981)

(amended 2017 to make jury’s verdict binding). After a separate hearing, the court

found the two statutory aggravating factors for which the State had argued: that the

murder was committed during the commission of a robbery, and that it was

committed during the commission of a kidnapping. See Ala. Code § 13A-5-49(4).




2
  “If anyone kills a person, the murderer shall be put to death on the evidence of witnesses. But
no person shall be put to death on the testimony of one witness.” Numbers 35:30 (ESV). Downey
also paraphrased Deuteronomy 17:6 as “On the evidence of two witnesses or three witnesses, he
is [sic] shall be put to death. He shall not be put to death on the evidence of one witness.”
                                               10
The court also found two statutory mitigating factors: that Jenkins had no

significant history of prior criminal activity, and his age at the time of the crime

(21). See 

(7). The court considered but rejected the statutory

mitigation that, due to his consumption of alcohol, Jenkins’s capacity to appreciate

the criminality of his conduct or to conform his conduct to the requirements of law

was substantially impaired. See 

The court found that the

aggravating circumstances outweighed the mitigating circumstances and, in

accordance with the jury’s recommendation, imposed a sentence of death.

             C.      The State and Federal Post-Conviction Proceedings

       On direct appeal, the Alabama Court of Criminal Appeals affirmed Jenkins’s

conviction and death sentence. Jenkins v. State, 

(Ala. Ct. Crim.

App. 1992), aff’d, 

(Ala. 1993), cert. denied, 

(1994). In 1995, Jenkins filed his first petition for state postconviction relief, Ala.

R. Crim. P. 32,3 alleging, among many other things, that he received ineffective

assistance of counsel during his penalty phase. The Rule 32 trial court conducted a

three-day hearing at which evidence was presented about the performance of

Jenkins’s attorneys.

  “Subject to the limitations of Rule 32.2, any defendant who has been convicted of a criminal
offense may institute a proceeding in the court of original conviction to secure appropriate relief
on the ground that . . . [t]he constitution of the United States or of the State of Alabama requires
a new trial, a new sentence proceeding, or other relief. . . .” Ala. R. Crim. P. 32.1.
                                                 11
      Scofield testified about the representation that he and Downey provided. In

relevant part, Scofield asserted that he and Downey had “decided that [developing

mitigation for the penalty phase] would be something that Stan [Downey] would

handle.” Downey later told Scofield that he hadn’t done any such investigation, but

Scofield admitted that, “[a]part from what he has told me, I don’t know what he

has done.” Scofield testified that Downey “didn’t appear prepared” for the penalty

phase, based on Downey’s last-minute suggestion that Scofield examine Seal since

he had talked with him before.

      In preparation for the penalty phase, Scofield himself did not interview any

member of Jenkins’s family, but he did not know whether Downey interviewed

any family members. Scofield did interview Jenkins’s landlord and some other

acquaintances but did not do so specifically for the purpose of developing

mitigation. He had met with Jenkins around a dozen times, and Jenkins had told

him his life story including his experience of abuse as a child. In hindsight,

Scofield said he had a “lack of appreciation of mitigating circumstances.” He

repeatedly denied in his Rule 32 testimony that his omissions during the penalty

phase were strategic: “I didn’t understand what I was doing. . . . I just didn’t

understand what I needed to do.”

      For reasons that remain unclear, Downey—who is since deceased—did not

testify or submit an affidavit in the Rule 32 proceeding. Scofield answered,


                                          12
“Obviously not,” when asked whether he had personal knowledge of everything

Downey may or may not have done to prepare for the penalty phase. The record of

the extent of Downey’s pretrial preparation is thus limited to Downey’s detailed

fee declaration, which he submitted to the State of Alabama in documentation of

the compensation due him as appointed counsel. See Ala. Code § 15-12-21. In it,

Downey reported that he spent 71 hours4 on out-of-court preparation for trial. The

report details 35 hours of interviews with Jenkins in 18 separate visits to the jail

over the course of 17 months, as well as one substantive conversation with

Jenkins’s grandmother.5

       The Rule 32 trial court also heard testimony from four family members and

one friend of Jenkins’s. The family members presented for the first time a stark

depiction of Jenkins as an unloved and abused child in California. Jenkins’s older

brother Michael Jenkins testified that all of his siblings have different fathers and

that his parents often used drugs and fought. Michael testified that Jenkins was

beaten frequently as a child by his stepfather, if not every day then every other day

  In Jenkins’s state postconviction appeal, the Alabama Court of Criminal Appeals erroneously
stated that Downey’s fee declaration reports 171 hours of pretrial preparation. See 

. We discuss the effect of this discrepancy infra note 7.

  The state appellate court also noted that Downey had moved for a continuance in October 1989
so that he could conduct “[f]urther discovery and investigation (including a possible trip to
California).” 

that Scofield had orally suggested to the trial court in September 1989
that more time might be needed with respect to “evidence about the defendant” and witnesses in
California, as well as possible psychological evaluation.

or every three days. Jenkins was beaten all over his body with a variety of

implements. Michael was beaten too. Jenkins’s stepfather would lock Jenkins in

his bedroom for a couple of hours at a time, sometimes without dinner. Some of

the beatings were prompted by Jenkins’s bedwetting or soiling. Michael testified

that Jenkins’s stepfather sometimes made Jenkins wear his soiled underwear on his

head and even forced him to eat his own feces a few times. Michael testified that

Jenkins’s bladder and bowel control problems began after a camping trip he took

with his stepfather and stepgrandfather.

      Michael testified that, as children, he and Jenkins were made to work on car

engines late into the night and to shovel horse manure daily. The family moved

frequently and the children attended many different schools as a result. Michael

testified that he was Jenkins’s only friend as a child and that Jenkins did poorly in

school. Jenkins began running away from home as a young teenager and lived with

various other family members or on the streets. Michael said that Jenkins was a

good brother to him and had asked him to testify at his trial, but he never heard

from his attorneys or found out when the trial was. Michael admitted to having

cognitive and memory problems due to a head injury years earlier.

      Jenkins’s cousin Tammy Pitts testified that, as an infant, Jenkins’s mother

beat and neglected him, leaving him dirty and in soiled diapers. His stepfather also

beat Jenkins daily until he left home at age 13, sometimes bruising him so badly


                                           14
that he was laid up in bed for days or weeks. Jenkins had problems with

bedwetting and soiling, and his stepfather made him wear soiled clothes to school.

Jenkins would be locked in his filthy bedroom around the clock except to attend

school and do chores. He was usually not allowed to eat dinner with the rest of the

family and subsisted on scraps and dog food. The entire family belittled Jenkins

because his biological father was Hispanic and his complexion was therefore

darker. Jenkins’s parents drank a lot and used drugs every day. Pitts knew these

things because she had daily contact with the family and lived with them off and

on, and Jenkins lived with her for a time after he ran away from home. No one had

contacted her about testifying at Jenkins’s trial.

      Jenkins’s second cousin Betty DeLavega testified that her relationship with

Jenkins was like that of an aunt. She lived with the Jenkins family for five months

when Jenkins was 10 or 11. She saw Jenkins’s stepfather slap Jenkins “[q]uite a

few times,” and once, he made Jenkins eat his own feces. DeLavega testified that

Jenkins’s parents used drugs nearly every day and withheld affection from Jenkins

and Michael. No one contacted her about Jenkins’s trial; Jenkins’s grandmother

had asked her to testify in the Rule 32 hearing about any abuse she had witnessed.

      Jenkins’s grandmother Doris Wagoner testified that while Jenkins’s mother

was pregnant with him, her husband was in prison and she drank and took drugs.

When Jenkins was born, his mother initially put him up for adoption, then changed


                                           15
her mind weeks later. Jenkins was a lethargic infant and his mother cared more

about partying than about her children. Wagoner testified that she heard of

Jenkins’s mistreatment as a child but didn’t see it. She could tell from the way that

Jenkins feared his stepfather that he was being abused, and she knew he slept in a

filthy bed. After Jenkins was arrested for murder, Wagoner spoke with Scofield,

who asked for money relating to his representation of Jenkins. She did not

remember whether she talked with Scofield about Jenkins’s background. She could

not remember why she didn’t testify at the trial; she might have been ill, but she

was probably busy.

      Sherry Seal, the wife of Lonnie Seal, who had testified in the penalty phase

of the trial, testified that Jenkins was respectful and generous and that she trusted

him with her children. She related how he supported her family after moving to

Alabama, giving them “pretty much” his entire paycheck. She said she would still

feel safe around Jenkins. Two jailers also testified that Jenkins was a respectful,

courteous, model inmate who never complained or caused any problems.

      Jenkins also introduced medical, school, and juvenile court records from his

childhood. The medical records document his premature birth and his mother’s

intention to give him up for adoption. The school records reflect a struggling

student who was repeatedly promoted to the next grade because of his age, despite

serious academic difficulties, chronic truancy, and frequent school changes. The


                                          16
juvenile court records document Jenkins’s placement in juvenile hall starting at age

14, following repeated acts of grand theft auto and running away.

      The Rule 32 hearing concluded with the testimony of two psychologists

about Jenkins’s history of psychological trauma stemming from his childhood

abuse. The defense expert, Dr. David Lisak, had met with Jenkins three times and

interviewed a dozen of his family members, family friends, and associates. Dr.

Lisak testified that the pervasive abuse and neglect in Jenkins’s childhood impaired

his ability to cope with trauma as an adult. He opined that Jenkins’s childhood

abuse adversely affected his cognitive and emotional development and other

abilities. He described how Jenkins had been neglected as an infant and sexually

abused by his grandfather at age four, which led to a lifetime of bladder and bowel

dysfunction. He also discussed the hypothesis that children who are abused are at

greater risk for perpetrating violence later in life, but he acknowledged there would

have been other causative factors in Jenkins’s case. Dr. Lisak described Jenkins’s

intellectual capacity as “somewhat borderline,” though he did not perform any

testing of his own.

      The State’s expert, Dr. Karl Kirkland, had met with Jenkins for several hours

and administered several tests. On the Wechsler Adult Intelligence Scale, Jenkins

“scored in the range of borderline intellectual functioning which is between mild

mental retardation and low average intellectual functioning” with an overall IQ of


                                         17
76. Dr. Kirkland agreed that Jenkins had been “reared in a chaotic dysfunctional

family” and generally agreed with Dr. Lisak’s assessment of the negative effects of

childhood trauma.

      The court considered all of this evidence before denying Rule 32 relief in

full. As relevant here, it found that some of the evidence about the severity of

abuse that Jenkins suffered as a child was not credible. It further found that Jenkins

suffered no prejudice from any deficient performance by his penalty-phase counsel

because the aggravating circumstances outweighed any additional mitigating

evidence Downey might have adduced.

      The Alabama Court of Criminal Appeals affirmed the denial of Rule 32

relief. Jenkins v. State, 

(Ala. Ct. Crim. App. 2004). In relevant part,

the appeals court rejected Jenkins’s ineffective assistance claim, finding that

counsel reasonably chose to pursue a penalty-phase strategy of residual doubt and

good character. 

It explained that the new evidence was self-

contradictory in that it asserted that childhood abuse would have made Jenkins a

violent adult yet also asserted that Jenkins was meek and mild. 

court also agreed with the lower court’s conclusion that Jenkins suffered no

prejudice from any error by his counsel because the aggravating circumstances still

outweighed any new mitigating ones. 

The court also noted that evidence




                                          18
about Jenkins’s good behavior in jail awaiting trial was “minimally mitigating” and

would not have affected the sentence. 

       Because the Supreme Court’s decision in Atkins v. Virginia6 had issued

during the pendency of the Rule 32 appeal, the Alabama appeals court ordered

supplemental briefing on the possible impact of Atkins upon Jenkins’s sentence.

Jenkins asked the court to stay the proceedings and conduct an evidentiary hearing

after the Alabama legislature enacted a statute about executing the mentally

retarded or, in the alternative, to vacate his sentence and remand after the Alabama

legislature acted. He later asserted that he is mentally retarded and therefore

ineligible for the death penalty. The appeals court proceeded to reject Jenkins’s

Atkins claim on the merits because the record established that his IQ was 76 and

that he maintained relationships and employment. 

The Alabama

Supreme Court summarily affirmed, in relevant part. Ex parte Jenkins, 

, 165 (Ala. 2005), remanded to 

(Ala. Ct. Crim. App. 2005)

(juror misconduct claim), cert. denied, 

(2008).

       In 2008, Jenkins filed his first petition for a writ of habeas corpus in federal

court pursuant to 28 U.S.C. § 2254. The federal proceedings were stayed for

courts, ultimately unsuccessfully. In the district court, Jenkins moved for an

evidentiary hearing on his Atkins claim. After reviewing the state court record,

with a focus on the Rule 32 testimony of Drs. Lisak and Kirkland, the district court

denied the motion in 2015. Noting that our Circuit has accepted the State of

Alabama’s definition of mental retardation following Atkins, the court found that

Jenkins is not intellectually disabled under that standard. In a 347-page order, the

district court also denied relief on all of Jenkins’s claims including ineffective

assistance of counsel during the penalty phase and affirmed as reasonable the state

court’s conclusion that Jenkins failed to establish prejudice from any error by his

counsel. The district court later denied reconsideration and a certificate of

appealability.

      Jenkins now appeals. Our Court granted Jenkins a certificate of

appealability, 28 U.S.C. § 2253(c), on two issues:

      1)     Whether the district court erred in denying Appellant’s claim
      that his trial counsel rendered ineffective assistance of counsel in the
      investigation and presentation of mitigating evidence during the
      penalty phase of Appellant’s 1991 trial; and

      2)     Whether the district court erred in denying Appellant’s claim
      that he is intellectually disabled and ineligible for the death penalty
      under Atkins v. Virginia, 

(2002).

                        II.    STANDARDS OF REVIEW

      We review the denial of a petition for a writ of habeas corpus de novo.

Morrow v. Warden, Ga. Diagnostic Prison, 

, 1146 (11th Cir. 2018).

                                          20
The Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA) instructs that

a writ of habeas corpus shall not be granted to a state prisoner unless the state

adjudication of a claim “resulted in a decision that was contrary to, or involved an

unreasonable application of, clearly established Federal law, as determined by the

Supreme Court of the United States.” 28 U.S.C. § 2254(d)(1). “[C]learly

established Federal law” means “the holdings, as opposed to the dicta, of [the

Supreme] Court’s decisions as of the time of the relevant state-court decision.”

Williams v. Taylor, 

, 412 (2000). “[W]hen the last state court to

decide a prisoner’s federal claim explains its decision on the merits in a reasoned

opinion . . . a federal habeas court simply reviews the specific reasons given by the

state court and defers to those reasons if they are reasonable.” Wilson v. Sellers,

, 1192 (2018). A state court’s decision is reasonable “so long as

‘fairminded jurists could disagree’ on the correctness of the state court’s decision.”

Harrington v. Richter, 

, 101 (2011) (quoting Yarborough v. Alvarado,

, 664 (2004)). “[E]ven a strong case for relief does not mean the state

court’s contrary conclusion was unreasonable.” 

Rather, a prisoner must

show that the state court’s ruling “was so lacking in justification that there was an

error well understood and comprehended in existing law beyond any possibility for

fairminded disagreement.” 

That ruling must have been “‘objectively

unreasonable,’ not merely wrong; even ‘clear error’ will not suffice.” White v.


                                          21
Woodall, 

, 419 (2014) (quoting Lockyer v. Andrade, 

, 75

(2003)).

      In addition, “a determination of a factual issue made by a State court shall be

presumed to be correct,” and the prisoner bears “the burden of rebutting the

presumption of correctness by clear and convincing evidence.” 28 U.S.C.

§ 2254(e)(1). AEDPA further instructs that a writ of habeas corpus may not be

granted unless the state court adjudication “resulted in a decision that was based on

an unreasonable determination of the facts in light of the evidence presented in the

State court proceeding.” 

When a federal habeas court makes a

factual finding as part of its habeas determination, we review for clear error, which

is a “highly deferential” standard of review. Thomas v. Allen, 

, 752

(11th Cir. 2010) (quoting Holton v. City of Thomasville Sch. Dist., 

,

1350 (11th Cir. 2005)). “A finding is ‘clearly erroneous’ when although there is

evidence to support it, the reviewing court on the entire evidence is left with the

definite and firm conviction that a mistake has been committed.” United States v.

U.S. Gypsum Co., 

, 395 (1948).

                                III.   DISCUSSION

                     A.     Ineffective Assistance of Counsel

      A prisoner alleging that he received ineffective assistance of counsel in

violation of the Sixth Amendment must establish two elements. Strickland v.


                                          22
Washington, 

, 687 (1984). “First, the defendant must show that

words, he must show “that

counsel made errors so serious that counsel was not functioning as the ‘counsel’

guaranteed the defendant by the Sixth Amendment.” 

defendant

must show that the deficient performance prejudiced the defense.” 

each of these elements in turn.

                            1.    Deficient Performance

      A “doubly” deferential lens sits before our eyes as we review the

performance of Jenkins’s counsel during the penalty phase. 

(quoting Knowles v. Mirzayance, 

, 123 (2009)). This redoubled

deference arises out of the tandem application of AEDPA’s “highly deferential”

review of a state court’s decision with Strickland’s “highly deferential” review of

an attorney’s performance. 

v. Murphy, 

, 333 n.7

(1997), and 

). Under the Strickland standard, “counsel

is strongly presumed to have rendered adequate assistance and made all significant

decisions in the exercise of reasonable professional judgment.” 

. And under AEPDA, we must deny habeas relief if “there is any

reasonable argument that counsel satisfied Strickland’s deferential standard.”

.




                                         23
      Jenkins argues that his counsel performed deficiently by failing to

“investigate compelling mitigating evidence or develop a penalty-phase theory.”

The state court disagreed. It quoted decisions of our Court that hold that “there is

no per se rule that evidence of a criminal defendant’s troubled childhood must

always be presented as mitigating evidence.” 

(quoting

Marek v. Singletary, 

, 1300 (11th Cir. 1995)). Noting that “Downey

was in charge of the penalty phase” but “we do not have the benefit of Downey’s

testimony as to what occurred and why,” it reviewed the trial record to find that

“counsel argued residual doubt and Jenkins’s good character at the penalty phase.”

It concluded that “Downey’s decision to concentrate on reasonable

doubt and to portray Jenkins as a good person was reasonable under the

circumstances.” 

      Jenkins insists, however, that counsel’s failure to develop mitigating

evidence about his childhood abuse was “not the product of strategy, but rather

arose from ingnorance and inexeperiance [sic].” The problem for Jenkins is that,

like the state courts, this Court also does not know what Downey did or why. The

record is silent as to his thoughts and intentions as he prepared for the penalty

phase. Given that Jenkins bore the burden of overcoming the strong presumption of

competence and of proving Downey’s deficient performance, we are perplexed

why Jenkins’s new counsel did not have Downey testify or submit an affidavit in


                                          24
the Rule 32 proceeding. See 

(“The defendant must

show that counsel’s performance was deficient.”). Nor did Jenkins testify to the

substance of his conversations with his counsel. “The reasonableness of a trial

counsel’s acts, including lack of investigation or excluding character witnesses

from the sentencing phase, depends ‘critically’ upon what information the client

communicated to counsel.” Chandler v. United States, 

, 1324 (11th

Cir. 2000) (en banc) (quoting 

). There is simply no

record evidence to support Jenkins’s central assertion that Downey made no

tactical choices in his preparation for the penalty phase.

      Jenkins instead relies on Scofield’s Rule 32 testimony about how he and

Downey prepared for the trial and sentencing. We acknowledge that Scofield

repeatedly testified that he did not really know what he was doing and that he

failed to make strategic choices with respect to mitigating circumstances and

sentencing. But Scofield was equally clear that Downey—the more experienced

lawyer—was in fact responsible for the penalty phase. And Scofield also

repeatedly testified that he did not know what Downey may or may not have done

to prepare. Furthermore, his lack of knowledge about Downey’s preparation was

understandable. He and Downey were not colleagues who shared an office and

might reasonably be expected to know what the other was doing much of the time.

Scofield and Downey did not even work in the same city.


                                          25
      This case is unlike those in which we have found deficient performance

where the record showed that counsel investigated insufficiently because he

“waited until the eleventh hour” to begin preparing for the penalty phase while

faced with “overwhelming evidence of guilt.” See, e.g., Johnson v. Sec’y, D.O.C.,

, 932 (11th Cir. 2011). The limited record that Jenkins developed

establishes that Downey spent at least 71 hours preparing for trial, spread out over

17 months. The state court interpreted this sparse record as reflecting a penalty-

phase strategy of residual doubt, the logical extension of Downey’s guilt-phase

investigation of the evidence and Scofield’s pursuit at trial of an acquittal based on

reasonable doubt. See 

. In such a situation, “[a] lawyer’s

time and effort in preparing to defend his client in the guilt phase of a capital case

continues to count at the sentencing phase.” Tarver v. Hopper, 

, 715

(11th Cir. 1999).

      We decline to dictate how many hours or how many sessions an attorney

must spend interviewing his counsel in order to provide effective assistance. “No

absolute rules dictate what is reasonable performance for lawyers.” 

(citing 

–89). But even this limited record

undermines Jenkins’s assertion that Downey prepared inadequately. Downey’s 71

hours of preparation included 35 hours of jailhouse conversations with Jenkins




                                          26
during 18 separate meetings.7 According to Downey’s notes, Scofield was present

for only five of those meetings (12 hours’ worth), leaving 23 hours over 13

meetings between Jenkins and Downey alone. Downey’s notes reveal little about

the content of those conversations beyond broad notations such as “evidence,

witnesses, general status,” and discussions with Jenkins of the evidence and

testimony against him were surely relevant to Downey’s penalty-phase strategy of

residual doubt.

       But the record does not reveal that Downey knew or should have known that

Jenkins’s childhood merited investigation beyond that which he may have done.

The record shows that Downey developed enough of a rapport with Jenkins that,

according to his fee declaration, he “g[ave a] Christmas gift [and] discuss[ed] how

much to tell his family.” But how much Downey knew about Jenkins’s family

background can only be guessed from Scofield’s Rule 32 hearing testimony.

Scofield testified that he discussed Jenkins’s background during his dozen or so

jailhouse meetings with him, and that Downey was present for some of those

meetings. Scofield—and possibly Downey—learned that Jenkins experienced

abuse as a child, that his stepfather was brutal, and that he lived on the streets and




7
  We note that the state court clearly erroneously stated that Downey’s fee declaration
documented 171 hours of pretrial preparation. See 

. However, the state
court accurately stated that “he spent over 25 hours talking with Jenkins in more than 10 visits to
the jail.” 

was not an unreasonable determination of the facts.
                                                27
in juvenile institutions because of his brutal home life. It is against this backdrop

that Downey’s presumptive “decision not to investigate must be directly assessed

for reasonableness in all the circumstances, applying a heavy measure of deference

to counsel’s judgments.” 

.

      That assessment depends a great deal on what Jenkins told his counsel about

his background. See 

do not know whether Downey was present when

Scofield learned about Jenkins’s childhood abuse, nor what else Downey may have

learned during his 13 solo discussions with Jenkins. Therefore, “given the absence

of evidence in the record, we must assume counsel carried out his professional

responsibility and discussed mitigation with his client.” 

. We will not “turn that presumption on its head by giving [Jenkins] the

benefit of the doubt where it is unclear what [Downey] did or did not do.” Williams

v. Head, 

, 1235 (11th Cir. 1999). We will not assume that Jenkins

told Downey more than he told Scofield, and Scofield denied remembering that

Jenkins told him about the severity or frequency of his stepfather’s physical abuse.

He denied remembering Jenkins telling him about being beaten daily, being locked

in his room 24/7, or being forced to eat his feces. And there is no suggestion in the

record that counsel knew or had reason to investigate the allegation of sexual abuse

by his stepgrandfather. The record simply does not reflect that Jenkins told either

of his lawyers about the severe abuse that some of the Rule 32 witnesses later


                                          28
described. We will not fault those lawyers for failing to present as mitigation this

limited evidence that they may have reasonably believed to be unremarkable. See

.

      To be sure, counsel’s failure “to discover all reasonably available mitigating

evidence” may constitute deficient performance in some cases. Wiggins v. Smith,

, 524 (2003) (quoting ABA Guidelines for the Appointment and

Performance of Counsel in Death Penalty Cases § 11.4.1(C) (1989)). Our Court

has identified deficient performance in several instances where counsel had good

reason to investigate the defendant’s background but failed to do so. See 

(collecting cases). But we assess “a particular decision not to

investigate . . . for reasonableness in all the circumstances, applying a heavy

measure of deference to counsel’s judgments.” 

. Thus,

we have rejected a hard rule that counsel’s “strategic decisions can be considered

reasonable only if they are preceded by a ‘thorough investigation.’” 

(quoting Rogers v. Zant, 

, 387 (11th Cir. 1994)). Because

we simply do not know why Downey chose not to investigate Jenkins’s childhood

more thoroughly, Downey is entitled to the presumption that this strategic decision

was reasonable.

      And though we have also rejected “a per se rule of ineffective assistance

where counsel does not consult family members,” Holladay v. Haley, 

1243, 1252 (11th Cir. 2000), we note that Downey did not fail altogether to consult

family members. Downey had at least one substantive conversation with Jenkins’s

grandmother, and we know from her Rule 32 hearing testimony that she never

witnessed Jenkins’s childhood abuse. Given the silence of the record and the strong

presumption of competence to which Downey is entitled, we decline to fault him

for not doing more when Jenkins and his grandmother did not and could not,

respectively, provide a basis for doing so. Cf. United States v. Pease, 

,

941–92 (11th Cir. 2001) (“we cannot say as a matter of law that reliance on a

client’s statements is per se deficient performance”). Nor did Jenkins’s counsel

have an absolute duty to put on abusive-childhood evidence, even if they knew of

it. See 

(“Counsel is not required to present every

nonfrivolous defense; nor is counsel required to present all mitigation evidence,

even if the additional mitigation evidence would not have been incompatible with

counsel’s strategy.”); Waters v. Thomas, 

, 1511 (11th Cir. 1995) (en

banc) (“Our decisions are inconsistent with any notion that counsel must present

all available mitigating circumstance evidence.”).

      Instead, we affirm as a reasonable application of Strickland the state court’s

conclusion that Downey’s strategic decision to emphasize residual doubt was

reasonable. See 

. As we have noted, “[a] lawyer’s time

and effort in preparing to defend his client in the guilt phase of a capital case


                                          30
continues to count at the sentencing phase.” 

. This

reasoning is especially applicable where, as here, counsel pursued the reasonable

strategy of arguing for acquittal at the guilt phase and for life at the sentencing

phase by highlighting doubt about the evidence. “[R]esidual doubt is perhaps the

most effective strategy to employ at sentencing.” 

n.28.

“[E]specially when—as in this case—the evidence of guilt was not overwhelming,

we expect that petitioners can rarely (if ever) prove a lawyer to be ineffective for

relying on this seemingly reasonable strategy to defend his client.” 

(footnote omitted); see also 

–16 (collecting law review

articles on the merits of residual-doubt strategy). Not only can such a strategy be

constitutionally adequate, in some cases it may be “the most effective performance

in defense to the death penalty.” 

.

       We cannot say that Downey’s manifest strategy of residual doubt was

objectively unreasonable under the circumstances. Jenkins’s case is precisely the

sort where reminding the jury of the misgivings it may have held about the State’s

case could have been effective. Scofield’s guilt-phase closing argument from that

very morning, which explicitly emphasized doubt and the weakness of the State’s

evidence, would have been fresh in the minds of the jury.8 Although we are not


8
 During the penalty phase of a capital case, “[e]vidence presented at the trial of the case may be
considered insofar as it is relevant to the aggravating and mitigating circumstances without the
necessity of re-introducing that evidence at the sentence hearing.” Ala. Code § 13A-5-45(c).
                                                31
questioning the jury’s guilty verdict or the sufficiency of the evidence, which are

beyond the scope of our habeas review, we acknowledge that the State’s case

against Jenkins was—as Downey reminded the jury during the penalty phase—

entirely circumstantial. Indeed, Scofield maintained post-conviction that the case

for reasonable doubt was “[v]ery strong.” No one saw Jenkins commit either the

murder or the robbery and kidnapping that elevated Hogeland’s murder to a capital

crime. Scofield’s guilt-phase closing argument challenged the inferential leaps the

State was asking the jury to make in finding that Jenkins committed these capital-

predicate offenses and that he formed the intent to kill. This situation was not one

where a guilt-phase strategy of acquittal—and therefore a penalty-phase strategy of

residual doubt—was unreasonable in light of the evidence. Cf. 

–33 (deficient sentencing investigation where defendant had confessed to

two murders).

      Thus, although Downey’s penalty-phase closing argument did not

specifically invoke lingering doubt, it clearly reminded the jury of the entirely

circumstantial nature of the State’s guilt-phase case. See 

& n.6 (a strategy of “focus[ing] on obtaining an acquittal and then, at

sentencing, on lingering doubt” is reasonable, even if counsel does not use the

words “lingering doubt” or “residual doubt”). Downey closed this reminder by

explaining to the jury how a foundational ancient legal system proscribed capital


                                          32
punishment in the absence of eyewitness testimony—the exact situation here. The

state court found that Downey’s penalty-phase closing argument reflected a

strategic “decision to concentrate on reasonable doubt,” see 

, a tactical choice entitled to a “strong presumption of correctness,” 

& n.3.

       Jenkins suggests other theories of mitigation that Downey might have more

effectively pursued,9 but our deferential review under Strickland does not ask

whether counsel could possibly or ideally have been more effective. “The test for

ineffectiveness is not whether counsel could have done more.” 

. We do not ask whether an attorney’s representation “deviated from best

practices or common custom,” and we should resist the temptation to second-guess

an attorney with the benefit of our hindsight. 

. We ask only

“whether, in light of all the circumstances, the identified acts or omissions were




9
  In particular, Jenkins argues that his counsel should have presented “model prisoner” evidence.
The state court noted, “Good conduct during pretrial incarceration is not necessarily a mitigating
circumstance,” before finding that Jenkins had not met his burden of establishing that his counsel
even had information about his conduct in jail. 

. We agree, and we
decline to impose a requirement of sua sponte investigation of this kind in every capital case. Cf.

(finding deficient performance based in part on not returning a call
from a prison ministry volunteer who offered to vouch for defendant’s good behavior in prison).
“Surely, counsel is not required to call a witness to testify to facts such as lack of violent nature
when the jury has rejected such an approach and has found that the defendant is guilty of
murder.” Griffin v. Wainwright, 

, 1512 (11th Cir. 1985), vacated on other grounds,

(1986), reaff’d, 

(11th Cir. 1989).
                                                 33
outside the range of professionally competent assistance.” 

.

       We conclude that the state court did not unreasonably determine that Jenkins

failed to establish objectively incompetent performance by his counsel during the

penalty phase of his trial. Our inquiry is not “what the best lawyers would have

done. Nor is the test even what most good lawyers would have done. We ask only

whether some reasonable lawyer at the trial could have acted, in the circumstances,

as defense counsel acted at trial. . . . We are not interested in grading lawyers’

performances.” White v. Singletary, 

, 1220–21 (11th Cir. 1992). And

“[i]f fairminded jurists could reasonably disagree” about the reasonableness of

counsel’s performance, “then habeas relief is due to be denied.” 

.

                                   2.     Prejudice

       Even if Jenkins had demonstrated that his counsel performed as no

reasonable lawyer could have, he must also demonstrate a “reasonable probability

that, but for counsel’s unprofessional errors, the result of the proceeding would

have been different.” 

. Given that the jury here

recommended a sentence of death by the narrowest possible vote, 10 to 2, Jenkins

need establish only “a reasonable probability that at least one juror would have

struck a different balance” between life and death. 

. “A


                                          34
reasonable probability is a probability sufficient to undermine confidence in the

outcome.” 

. In measuring that probability here, we will

“evaluate the totality of the available mitigation evidence—both that adduced at

trial, and the evidence adduced in the habeas proceeding in reweighing it against

the evidence in aggravation.” 

–98.

       We begin our analysis by clarifying what exactly Jenkins is arguing about

prejudice. We do not know precisely which aggravating and mitigating factors the

jury may have implicitly found before making its recommendation of death. The

trial court found at sentencing two statutory aggravating factors: the robbery and

the kidnapping of the victim. See Ala. Code § 13A-5-49(4). Because none of the

mitigation evidence offered in the Rule 32 hearing bears on those factors, we see

no reasonable probability that the aggravating factors would have been determined

differently by the jury or the court. The court also found at sentencing two

statutory mitigating factors: no significant history of prior criminal activity and

age. See 

(7). There was also strong evidence of Jenkins’s

intoxication, which was a key part of Jenkins’s guilt-phase defense and could have

supported a third mitigating factor, impaired capacity. See 

10


10
  The jury had heard evidence about all three of these statutory mitigators during the guilt phase
of the trial. Downey’s penalty-phase opening statement reviewed for the jury all seven of the
possible statutory mitigating factors, and the court also recited them in its jury instructions,
reminding the jury that they could consider guilt-phase evidence as well as non-statutory
mitigation. Jenkins has not established that there is a substantial probability that the jury’s
recommendation would have been different had it been more explicitly reminded of Jenkins’s
                                                35
Jenkins does not argue that the jury or the court would have found other statutory

mitigators in light of the Rule 32 evidence. Rather, he contends that the jury might

have found non-statutory mitigation based on Jenkins’s abusive childhood, low

intelligence, or mental health problems that would have outweighed the

aggravating factors.11

       The Rule 32 trial court found that Jenkins had not demonstrated prejudice

even assuming that counsel had performed deficiently. See 

. It concluded that he had not shown a reasonable probability that the sentencer

“would have concluded that a weighing of the aggravating and mitigating

circumstances did not warrant death” upon a reweighing of the evidence. See 

the depravity of the crime and the aggravating circumstances and

found that the mitigating witnesses were not credible for various reasons. See 

appellate court affirmed, declining to disturb the credibility

determinations of the trial court. 

Independently reweighing the


age, criminal history, and intoxication, given that the trial court, the Rule 32 trial court, and the
state appellate court all explicitly considered those mitigators and found them outweighed by the
aggravators.
11
    Alabama law lists seven statutory mitigating circumstances, but states that mitigation “shall
. . . not be limited to” those seven circumstances. Ala. Code § 13A-5-51. Further, “mitigating
circumstances shall include any aspect of a defendant’s character or record and any of the
circumstances of the offense that the defendant offers as a basis for a sentence of life
imprisonment without parole instead of death, and any other relevant mitigating circumstances
which the defendant offers as a basis for a sentence of life imprisonment without parole instead
of death.” 

A jury may recommend a sentence of death only if it finds that “one or
more aggravating circumstances . . . exist and that they outweigh the mitigating circumstances, if
any.” 

                                                 36
evidence, it concluded that, “[g]iven the aggravating circumstances that were

proven by the State and the facts surrounding Hogeland’s murder, we, like the

circuit court, are confident that death was the appropriate punishment for Jenkins’s

actions.” 

      Our review of this evidence does not show that it is likely that the jury

would have concluded that death was not the appropriate punishment if it had

heard the Rule 32 evidence. Much of the proffered mitigation evidence is, in our

view, much less mitigating than Jenkins asserts. In particular, the testimony of

Jenkins’s older brother Michael was likely to have been a double-edged sword. See

Evans v. Sec’y, Dep’t of Corr., 

, 1327 (11th Cir. 2013) (en banc) (“it

is reasonable to conclude that a defendant was not prejudiced when his mitigation

evidence was a two-edged sword” (quoting Ponticelli v. Sec’y, Fla. Dep’t of Corr.,

, 1296 (11th Cir. 2012)). Michael was the closest relative to testify at

the Rule 32 hearing and his testimony about the abuse Jenkins experienced should

have been the most reliable, since he experienced much of the same physical abuse

himself. The brothers shared the same filthy bedroom, received beatings from the

same paddle, and were frequently absent from school together. But Michael’s

testimony contained some discrepancies, and he admitted to cognitive and memory

problems. Perhaps Michael’s testimony would have made Jenkins appear more

sympathetic in the eyes of the jury—but perhaps not. While Jenkins ran away from


                                         37
home and eventually committed murder, Michael responded to the same

background by running away from home, graduating from high school, and

providing health care for both the terminally ill and people with substance use

disorders. It is possible that the jury could even have found Jenkins to be more

culpable for not overcoming his difficult upbringing and to pose more of a danger

of future violence.

      We also find reasonable the state court’s identification of other problems

with the mitigating evidence Jenkins argues should have been presented. Hearing

that evidence firsthand in the Rule 32 proceeding, the trial court found the

testimony of the cousins less credible in light of the lack of physical abuse

documented in the school health records. See 

(noting

that school records observed a rash and gingivitis). It faulted Pitts in particular for

purporting to have witnessed ongoing, severe abuse but taking only minimal,

ineffective steps to obtain outside help. See 

noted that DeLavega and

Wagoner actually testified that they never saw Jenkins beaten, and it noted all of

the witnesses’ interest in getting Jenkins off death row. All of these factors would

likely have caused a reasonable jury to discount their testimony. See 

We must accept the trial court’s views of the Rule 32 testimony. “In the absence of

clear and convincing evidence, we have no power on federal habeas review to

revisit the state court’s credibility determinations.” Bishop v. Warden, 

1243, 1259 (11th Cir. 2013) (citing Marshall v. Lonberger, 

, 434

(1983)).

      The state court also noted that Wagoner testified that she was not available

to testify at the trial, and it found that Seal’s testimony would have been

cumulative to that of her husband. Thus, counsel’s failure to call those two

witnesses could not have been prejudicial to Jenkins. See 

142. Neither of

these conclusions involves an unreasonable determination of the facts. We agree

that the Rule 32 testimony of Sherry Seal was substantially similar to the testimony

of her husband Lonnie Seal that the jury heard during the penalty phase. Both

testified about meeting Jenkins in California, Jenkins’s assistance with their move

to Alabama, and his residence with them in their Alabama home. Sherry added

only that Jenkins sometimes wet his bed. It was not unreasonable for the state court

to conclude that Sherry’s testimony was cumulative of her husband’s, and “a

petitioner cannot satisfy the prejudice prong of the Strickland test with evidence

that is merely cumulative of evidence already presented.” Rose v. McNeil, 

, 1243 (11th Cir. 2011).

      Further, the school, medical, and juvenile court records that Jenkins

introduced in the Rule 32 proceeding have their own problems. As noted, they do

not document or even corroborate the severe level of abuse alleged by some of the

witnesses. Though these documents tell a sad story, they do not create a substantial


                                          39
likelihood that the jury would have recommended life. Although they portray

Jenkins as a victim of truly unfortunate circumstances, they also show his unsavory

delinquent behavior. That delinquency included a history of stealing cars, and

given that the jury likely inferred that Jenkins stole the red Mazda, new

information about his history of theft may not have been especially mitigating.

Similarly, we agree with the state court that evidence of Jenkins’s compliant

conduct in pretrial detention is “minimally mitigating” where there had been no

evidence of jail misconduct as an aggravator. See 

; cf.

Skipper v. South Carolina, 

, 5 & n.1 (1986) (good jail behavior is

“potentially mitigating” especially “[w]here the prosecution specifically relies on a

prediction of future dangerousness in asking for the death penalty”).

      Jenkins argues that allowing the jury to see his experience of mental,

emotional, and cognitive difficulties, compounded by years of abuse and neglect

and considered alongside his mild character and good jail behavior as an adult,

would have convinced them that Hogeland’s murder was an “aberration” that

deserved a punishment less severe than death. That interpretation of Jenkins’s life

story may be conceivable. But more than mere conceivability is required to

establish prejudice: “The likelihood of a different result must be substantial, not

just conceivable.” 

(emphasis added). We do not find the

state court’s decision that a different result was not substantially likely to be an


                                           40
unreasonable application of Strickland. As we have noted, we think it equally

likely that the jury could have rejected this alternate narrative out of hand in light

of having just convicted him of the violent murder of a young mother. We also

think it possible that the jury could have viewed the murder as just one step in a

logical progression of degeneracy that began with behavioral problems at school,

continued through the juvenile court system, and escalated past grand theft auto

into kidnapping and murder. Taken separately as well as together, the proffered

evidence does not compel us to conclude that a verdict of life would have been

substantially likely. Because fairminded jurists could disagree about the state

court’s conclusion about Strickland prejudice, we affirm the denial of habeas relief

on this ground.

                               B.      Intellectual Disability

       Jenkins argues that the district court erred when it denied his claim that he is

intellectually disabled and ineligible for the death penalty under Atkins v. Virginia,

(2002). The Supreme Court held in Atkins that executing an offender

who has mental retardation12 violates the Eighth Amendment’s ban on excessive




12
  In 2002, the Atkins Court followed prevailing convention in referring to “mentally retarded”
offenders. We will use that now-disfavored term only when quoting or discussing older sources.
Since 2014, the Supreme Court has exclusively used the terms “intellectually disabled person”
and “person with intellectual disability.” See, e.g., Hall v. Florida, 

, 704 (2014);
Moore v. Texas, 

, 672 (2019).
                                               41
punishments. 

It defined mental retardation by quoting the American

Association on Mental Retardation:

       Mental retardation refers to substantial limitations in present
       functioning. It is characterized by significantly subaverage intellectual
       functioning, existing concurrently with related limitations in two or
       more of the following applicable adaptive skill areas: communication,
       self-care, home living, social skills, community use, self-direction,
       health and safety, functional academics, leisure, and work. Mental
       retardation manifests before age 18.

n.3. Alabama courts have followed that tripartite definition, adopting

what they consider the “broadest” definition of mental retardation for Atkins

purposes:

       [A] defendant, to be considered mentally retarded, must have
       significantly subaverage intellectual functioning (an IQ of 70 or
       below), and significant or substantial deficits in adaptive behavior.
       Additionally, these problems must have manifested themselves during
       the developmental period (i.e., before the defendant reached age 18).

Ex parte Perkins, 

, 456 (Ala. 2002).

       The clinical evidence adduced during the Rule 32 hearing with respect to

Jenkins’s intellectual ability was that his IQ was 76, reflecting “borderline

intellectual functioning.” The record also included the report of the Lunacy

Commission13 which found that Jenkins was competent to stand trial, as well as



13
   Alabama law requires a capital defendant to be “committed to the Department of Mental
Health and Mental Retardation for examination” if there is a question about his capacity to stand
trial or if there will be a mental-disease-or-defect defense. Ala. Code § 15-16-22(a). “The
assigned mental health professional(s) shall examine the defendant with respect to determining
the presence of any mental disease or defect which, if determined to be present, would affect the
                                               42
Jenkins’s school and juvenile court records. The court also considered all the

testimony it had heard about Jenkins and reviewed the transcript of his murder trial

before rejecting Jenkins’s claim of mental retardation.

       On appeal, after reciting the Perkins standard, the Alabama Court of

Criminal Appeals explained that Jenkins had not established mental retardation:

       Dr. Kirkland testified that he performed psychological tests on Jenkins
       and that Jenkins’s IQ was 76. There was evidence presented at
       Jenkins’s trial indicating that Jenkins maintained relationships with
       other individuals and that he had been employed by P.S. Edwards
       Landscaping Company, Cotton Lowe 76 Service Station, and
       Paramount Painting Company. The record fails to show that Jenkins
       meets the most liberal view of mental retardation adopted by the
       Alabama Supreme Court in Perkins.

. In this habeas appeal, Jenkins raises arguments about

all three components of the intellectual disability showing under Atkins and

Perkins, which we address in turn. He also appeals the denial of an evidentiary

hearing on this issue.

                                1.      Intellectual Function

       The first component of intellectual disability under Perkins is “significantly

subaverage intellectual functioning (an IQ of 70 or below).” 

. Jenkins argues that the use of a strict IQ cutoff of 70 was contrary to or an

unreasonable application of Atkins.


capacity of the defendant to proceed or continue to trial or which would affect the defendant’s
criminal responsibility at the time of the commission of the crime.” 

disagree. The state court’s decision that Jenkins failed to establish

mental retardation in this respect was a reasonable application of the record and of

Atkins. As a threshold matter, we note that the state court did not say it was

applying a strict cutoff of 70; it merely stated that Dr. Kirkland had measured

Jenkins’s IQ as 76. 

. Under our deferential review, the

question is whether the decision that Jenkins had not established the intellectual

functioning aspect of intellectual disability was an unreasonable application of

Atkins. The Supreme Court explained in Atkins that it was leaving “to the State[s]

the task of developing appropriate ways to enforce the constitutional restriction

upon [their] execution of sentences.” 

(quoting Ford v.

Wainwright, 

, 416–17 (1986)). In line with that invitation, our Circuit

has accepted Alabama’s judicial definition of intellectual disability as laid out in

Perkins.14 See 

–53. Jenkins objects, however, that the

Perkins standard, which he characterizes as articulating a “strict cutoff” of 70,

conflicts with more recent Supreme Court precedent that instead requires a

“clinical” definition that goes beyond a single IQ score.

       In particular, Jenkins points to Hall v. Florida, in which the Supreme Court

held that when an offender’s IQ is near but greater than 70, courts must take into



14
  Notwithstanding the urging of the Alabama Supreme Court, see 

n.1, the Alabama legislature has not enacted a statutory definition of intellectual disability.
                                                44
account the IQ test’s standard error of measurement as well as non-IQ evidence of

intellectual function. See Hall v. Florida, 

, 723 (2014) (“This Court

agrees with the medical experts that when a defendant’s IQ test score falls within

the test’s acknowledged and inherent margin of error, the defendant must be able

to present additional evidence of intellectual disability, including testimony

regarding adaptive deficits.”). But, as Jenkins concedes, our Circuit has

specifically held that Hall is not retroactive to cases on collateral review. See In re

Henry, 

, 1161 (11th Cir. 2014) (explaining that Hall does not supply

a new substantive rule but rather “merely provides new procedures for ensuring

that States do not execute members of an already protected group”). We also note

that Alabama courts have found the Perkins standard to comport with Hall in that

it does not prevent an offender from presenting the standard error of measurement

or non-IQ evidence of intellectual disability. See Reeves v. State, 

,

728–29 (Ala. Ct. Crim. App. 2016). Here, the state court did not unreasonably

apply Atkins when it analyzed the intellectual functioning component of

intellectual disability.

       Jenkins also argues that the state court’s decision on this component in his

Rule 32 proceeding resulted from an unreasonable determination of the facts. He

asserts that his IQ score of 76, when combined with the test’s standard error of

measurement and considered alongside the Flynn effect (which we discuss below),


                                          45
does show that he has significantly subaverage intellectual function. For the

reasons that follow, we disagree.

       Most fundamentally, neither of the clinicians who testified about Jenkins’s

intellectual ability in the Rule 32 hearing opined that he was mentally retarded.

The closest thing Jenkins can point to is the testimony of Dr. Kirkland that his IQ

is two standard deviations below the mean. But his entire testimony, in context, did

not establish intellectual disability. To the contrary: Dr. Kirkland testified that

Jenkins “scored in the range of borderline intellectual functioning which is

between mild mental retardation and low average intellectual functioning.”

Furthermore, Jenkins’s own expert Dr. Lisak fully reviewed Dr. Kirkland’s clinical

findings. He agreed with those findings, concluding that the IQ results show

“borderline intelligence.” It is tremendously significant that no clinical assessment

in the entire record of these proceedings has found that Jenkins has mental

retardation or intellectual disability.

       Jenkins nonetheless argues that his IQ score of 76 establishes the intellectual

component of intellectual ability when the standard error of measurement and the

Flynn effect are considered alongside that score. It was not unreasonable for the

state court to disagree. As we have discussed, Jenkins is not retroactively entitled

to have the state courts take into account the margin of error of the IQ test. That

statistical margin of error—5 points in this case—takes into account characteristics


                                           46
of the test and variations due to chance in order to state how confident the tester is

that the measured result accurately states Jenkins’s true, unknowable IQ. A result

of 76 with a standard error of measurement of 5 simply means that the tester is

68% confident that Jenkins’s true IQ falls between 71 and 81, and 95% confident

that his true IQ falls between 66 and 86. See David H. Kaye & David A. Freedman,

Reference Guide on Statistics, in Reference Manual on Scientific Evidence 211,

243–44 (3d ed. 2011); see also 

–39 (Alito, J., dissenting). Of

course, Jenkins would like us to consider only the possibility that the test result

overstated his IQ—but the standard error of measurement is a two-way street.

“[T]he standard error of measurement is a bi-directional concept that does not

carry with it a presumption that an individual’s IQ falls to the bottom of his IQ

range.” Ledford v. Warden, Ga. Diag. & Clas. Prison, 

, 641 (11th Cir.

2016).

      Even if Jenkins were somehow entitled to subtract the 5-point margin of

error from his score and thereby lower his “true” IQ to 71, he still would not satisfy

the clinical intellectual component of intellectual disability. Thus, he sought in the

district court to introduce evidence about the Flynn effect in order to bring his IQ

down to 70 or below. As our Court has explained, the Flynn effect “recognizes the

fact that IQ test scores have been increasing over time”:

      The Flynn effect acknowledges that as an intelligence test ages, or
      moves farther from the date on which it was standardized, or normed,
                                          47
      the mean score of the population as a whole on that assessment
      instrument increases, thereby artificially inflating the IQ scores of
      individual test subjects. Therefore, the IQ test scores must be
      recalibrated to keep all test subjects on a level playing field.

. We have said that “[a]n evaluator may also consider the

‘Flynn effect’” in assessing an offender’s possible intellectual disability, 

but neither we nor the Alabama Supreme Court nor the U.S.

Supreme Court have said that a court must consider it in order to reasonably apply

Atkins. See, e.g., 

(“This Court has repeatedly held that a

circuit court is not required to accept, consider, or apply the ‘Flynn Effect’ in

determining intellectual disability.”).

      More problematically, Jenkins did not raise the Flynn effect issue in the

Alabama state courts. Jenkins asserts that he implicitly raised it as part and parcel

of his Atkins claim during his Rule 32 appeal, but we do not agree that the

Alabama courts had a full and fair opportunity to consider this issue, because it

was not explicitly presented to them. See Kelley v. Sec’y for the Dep’t of Corr., 

, 1349–50 (11th Cir. 2004) (holding that one ineffective-assistance

argument was unexhausted despite the petitioner’s general presentation of a

Strickland claim in the state courts). Thus, under AEDPA, Jenkins is procedurally

barred from raising this unexhausted claim in his federal habeas petition. See 28

U.S.C. § 2254(b)(1)(A), (c); Mason v. Allen, 

, 1119 (11th Cir. 2010).

We will allow a prisoner to overcome a procedural bar if he establishes cause for
                                           48
his default and prejudice therefrom. See, e.g., Smith v. Jones, 

, 1138

(11th Cir. 2001). But Jenkins cannot establish prejudice from being barred from

asserting this claim now because the Supreme Court has not “clearly established”

that a court must consider the Flynn effect in assessing intellectual disability. Thus,

under AEDPA, it could not form the basis for a federal habeas claim. See 28

U.S.C. § 2254(d)(1). We therefore conclude that the state court did not

unreasonably determine the facts or unreasonably apply Atkins with respect to the

intellectual component of intellectual disability.

                              2.     Adaptive Function

      The second component of intellectual disability is “significant or substantial

deficits in adaptive behavior.” 

. Jenkins argues that the

state court, which mentioned only Jenkins’s successes in employment and social

skills, see 

, failed to consider his deficits. He adds that

even the mention of employment success does not tell the whole story. Jenkins

insists that his jobs were menial, his employers took advantage of him, and he held

the jobs for only a few months each.

      But the state court’s terse discussion of Jenkins’s adaptive behavior did not

involve an unreasonable determination of the facts or an unreasonable application

of Atkins. To the contrary, its decision on this issue was reasonable in light of both

the record and Atkins.


                                          49
      Atkins elaborated that the adaptive-skill component of intellectual disability

requires substantial present limitation in at least two of the following areas:

“communication, self-care, home living, social skills, community use, self-

direction, health and safety, functional academics, leisure, and work.” 

n.3 (quoting definition of American Association on Mental

Retardation). The record supports the state court’s judgment that Jenkins does not

have substantial deficits in at least two areas. To be sure, we will assume that

Jenkins may be substantially limited in functional academics; Dr. Kirkland

assessed his reading, spelling, and arithmetic skills at a third-grade level. But the

record does not compel a finding of substantial present deficits in the areas of

communication, self-care, home living, and work. Although Jenkins emphasizes

his transient employment, the record shows he was able to find work quickly, to

work hard to support the Seals’ household until Lonnie Seal found a job, and, later,

to move into his own home. That record evidence is inconsistent with a substantial

deficit in the area of work.

      As the State observes, the facts of the crime also fail to show significant

deficits in the areas of communication, self-care, community use, and self-

direction. Jenkins was able to communicate well enough to solicit an alibi and to

sell his car, including writing out a bill of sale. He then was able to arrange for his

flight from Alabama, including purchasing a bus ticket and hitchhiking across the


                                           50
country. Indeed, throughout his trial and postconviction proceedings, the people

who knew Jenkins as an adult consistently described a man who did not have

serious difficulties in communicating, forming relationships, working, and caring

for himself. No witness mentioned these kinds of difficulties in his or her

testimony about Jenkins. There was some evidence that Jenkins was “not

articulate” and that his house was messy, but that testimony does not rise to the

level of overwhelming evidence of substantial functional deficits that would

support a conclusion that the state court unreasonably determined the facts.

      Of course, the record also contains evidence of Jenkins’s childhood

academic and social deficits, attributable at least in part to his parents’ neglect, but

Jenkins’s childhood is not directly relevant to our consideration of his present

limitations. Although we acknowledge that the Supreme Court has noted that such

“risk factors” may support further exploration of the possibility of intellectual

disability, see Moore v. Texas, 

, 1051 (2017), the state court record

contains the results of that exploration. Overall, that record supports the state

court’s conclusion that Jenkins does not have substantial deficits in adaptive

behaviors.

                                3.     Juvenile Onset

      The third and final component of intellectual disability is manifestation of

the first and second components “before the defendant reached age 18.” Perkins,


                                           

. Jenkins asserts, the State assumes, and we agree that the state

court did not rule upon this issue, so there is nothing to which we must defer under

AEDPA. See, e.g., Brumfield v. Cain, 

, 2282 (2015). Thus, we will

review the district court’s legal conclusions on this issue de novo, and its factual

findings for clear error. See, e.g., Grossman v. McDonough, 

, 1335

(11th Cir. 2006). Jenkins argues that he has satisfied the age-of-onset component

by showing “a wide range of evidence of deficits in both intellectual and adaptive

functioning throughout Jenkins’s childhood.”

      In fact, the ample record of Jenkins’s childhood, as developed in the Rule 32

proceeding, does not point to intellectual disability before age 18. School

assessments at age 12 reported an IQ score of 83, an adaptive behavior rating of

“low,” and noted overall an intellectual capacity of “average,” a diagnosis of

dyslexia, and “poor functional skills.” The psychologist attributed Jenkins’s

difficulties to a combination of “[f]requent moves, changes in schools and family

instability” with “[l]ow ability coupled with a specific learning disability” and

“[l]ack of responsibility for self control and poor use of time.” Although Jenkins

failed several grades of school, teachers additionally attributed his difficulties to

his behavioral problems and his high number of absences from school.

      Similarly, IQ tests ordered by the juvenile court at age 14 gave scores of 81

and 86 on different tests, in the “[d]ull–[n]ormal” range and reflecting “a definite


                                           52
learning disability.” These records all show a child with serious academic deficits

and some intellectual and adaptive deficits, but they do not clearly show an

intellectually disabled child. In particular, Jenkins’s childhood IQ scores of 83, 81,

and 86 fail to point to intellectual disability or mental retardation. We are not left

with the definite and firm conviction that the district court erred when it found that

“Jenkins’s [childhood] intelligence scores and adaptive functioning skills were

attributable to his learning disability and other circumstances in his life, rather than

mental retardation.”

      In sum, we agree with the district court that the decision of the Alabama

Court of Criminal Appeals that Jenkins does not have intellectual disability was

not contrary to or an unreasonable application of Atkins v. Virginia.

                             4.     Evidentiary Hearing

      Finally, Jenkins argues that the district court erred when it denied his request

for an evidentiary hearing on his Atkins claim. If Jenkins diligently attempted to

present this claim in the state court, we review for abuse of discretion. Burgess v.

Comm’r, Ala. Dep’t of Corr., 

, 1320 (11th Cir. 2013). “The district

court abuses its discretion where ‘such a hearing could enable an applicant to prove

the petition’s factual allegations, which, if true, would entitle the applicant to

federal habeas relief.’” 

v. Landrigan, 

, 474

(2007)). If Jenkins did not diligently attempt to develop the factual basis for this


                                           53
claim in the state court, absent certain circumstances, he is not entitled to a hearing

and we will affirm the district court’s denial. 28 U.S.C. § 2254(e)(2).

      The parties strenuously dispute whether Jenkins diligently attempted to

present this issue in the state court. On the one hand, the State argues that Jenkins

failed to allege that he was mentally retarded even after the U.S. Supreme Court

decided Atkins in 2002. On the other hand, Jenkins asserts that he raised the

possibility of mental retardation as early as his original Rule 32 petition in 1995.

      As we have noted, shortly after the Supreme Court decided Atkins, the

Alabama Court of Criminal Appeals ordered supplemental briefing on the possible

impact of Atkins on Jenkins. Jenkins’s Rule 32 appeal was pending at that point,

having been fully briefed and orally argued in the state appellate court. Having

reviewed the state court records, we agree with the State that Jenkins did not

diligently attempt to present his Atkins claim in the state courts.

      “Diligence will require in the usual case that the prisoner, at a minimum,

seek an evidentiary hearing in state court.” 

. The record

clearly shows that Jenkins did not do so. In the initial supplemental brief on Atkins

he filed in 2002, Jenkins merely requested a future hearing after the Alabama

legislature’s enactment of a statute on executing the mentally retarded. Seventeen

years later, that contingency is still in the future. Only in his reply supplemental

brief did Jenkins then assert, for the first time ever, that he is mentally retarded.


                                           54
      We acknowledge that Jenkins’s initial Rule 32 petition included in its

allegations of ineffective assistance of counsel a list of unpresented mitigating

evidence including his “developmental[] impair[ment]” and “learning disabilities,

low intelligence, poor comprehension and retarded socialization skills.” We

conclude that these tangential Strickland references to his mental and social

abilities do not amount to diligence. Thus, because Jenkins did not diligently

attempt to develop the factual basis for his Atkins claim in the state courts, we

affirm the district court’s denial of his request for an evidentiary hearing.

      Even if Jenkins had diligently attempted to present this claim in the state

court, however, we conclude in the alternative that the district court did not abuse

its discretion when it denied a hearing. We agree, in light of the ample evidence

about intellectual ability that Jenkins adduced in support of his ineffective-

assistance claim, that such a hearing would not have enabled Jenkins to prove that

he is intellectually disabled. See 

.

                               IV.    CONCLUSION

      The denial of Jenkins’s petition for a writ of habeas corpus is

      AFFIRMED.




                                          55
WILSON, Circuit Judge, dissenting:

      Mark Jenkins must prove that the Alabama state courts acted unreasonably

in denying him post-conviction collateral relief. 28 U.S.C. § 2254(d)(1). Jenkins

has satisfied that burden as to his ineffective assistance of counsel claim. He has

also demonstrated that he is entitled to an evidentiary hearing regarding his Atkins

v. Virginia claim. Because the majority came to the opposite conclusions, I

dissent.

            I.     Ineffective Assistance of Counsel at Penalty Phase

      Jenkins first asserts that his trial counsel’s failure to investigate Jenkins’

abusive upbringing and to present any mitigating evidence at the penalty phase of

his trial constituted ineffective assistance of counsel. The majority rejects this

contention, concluding that the Alabama state courts did not act unreasonably in

denying Jenkins’ ineffective assistance of counsel claim on collateral review. I

disagree and maintain that Jenkins established both deficient performance and

prejudice, entitling him to habeas relief. See Strickland v. Washington, 

, 687 (1984).

   A. Deficient Performance

      The Alabama state courts concluded that Jenkins’ counsel, Stan Downey,

did not perform deficiently at the penalty phase. The majority finds that

conclusion reasonable primarily because Downey (1) was not obligated to
investigate Jenkins’ abusive childhood and (2) reasonably pursued a residual doubt

strategy at the penalty phase. But further review of the record requires me to part

company with the majority’s reasoning and, ultimately, persuades me that the

Alabama courts’ conclusion was indeed unreasonable. See 28 U.S.C. § 2254(d)(1)

(providing that a writ of habeas corpus should not be granted to a state prisoner

unless the state court adjudication involved “a decision that was contrary to, or

involved an unreasonable application of, clearly established Federal law, as

determined by the Supreme Court of the United States”).

      Jenkins offers numerous examples of how his counsel performed deficiently

at the penalty phase of trial. First, counsel failed to thoroughly investigate Jenkins’

abusive childhood—an error that constitutes deficient performance. In Williams v.

Allen, we held that counsel’s failure to investigate mitigating evidence at the

penalty stage constituted ineffective assistance of counsel because counsel drew

upon only three sources of information—a psychologist’s report, a presentence

investigation report, and an interview with the appellant’s mother. 

,

1340 (11th Cir. 2008); see also Debruce v. Comm’r, Ala. Dep’t of Corr., 

, 1270, 1273–74 (11th Cir. 2014) (finding counsel’s performance deficient

where counsel interviewed the petitioner and his mother, but failed to contact

expert witnesses or other family members). In that case, we concluded that




                                          57
counsel’s lack of investigation resulted in “an incomplete and misleading

understanding of Williams’s life history.” 

.

       Jenkins’ counsel did even less than the attorneys in Williams and Debruce.

That is, Jenkins’ counsel conducted no investigation. Downey did not consider

Jenkins’ poor school records, mention Jenkins’ juvenile history, produce

documentary evidence that Jenkins suffered from severe depression, or pursue

records demonstrating Jenkins’ significant deficits in cognitive functions. We have

previously found that a counsel’s failure to investigate these rudimentary examples

of mitigating evidence constitutes ineffective assistance of counsel. See Daniel v.

Comm’r, Ala. Dep’t of Corr., 

(2016) (reversing and remanding

district court’s dismissal of the ineffective assistance of counsel claim and noting

how counsel should have more thoroughly investigated Daniel’s history of

physical and sexual abuse, his poor school records, and evidence of a potential

intellectual disability).

       Given the lack of preparation, it is not surprising that Downey failed to call

any witnesses to testify at the penalty stage about Jenkins’ childhood, thus failing

to give a complete depiction of Jenkins’ “excruciating life history.” Wiggins v.

Smith, 

, 537 (2003) (finding deficient performance where counsel did

not adequately investigate petitioner’s life history for mitigating evidence); see

also 

, 1273–74; Johnson v. Sec’y, Dep’t of Corr., 643


                                          

, 932 (11th Cir. 2011) (“No reasonable attorney, after being told by his

client that he had an abusive upbringing, would fail to interview members of his

family who were readily available and could corroborate or refute the allegations

of abuse.”).1 If Downey had effectively investigated—or investigated at all—he

would have been aware of several available and informed witnesses. Ultimately,

only one witness testified at the penalty phase: Lonnie Seal.2 Downey met with

Seal for only fifteen minutes before the penalty phase began. That fifteen minutes

represents the extent of Downey’s preparation for the penalty phase—a wholly

inadequate amount of time under Supreme Court precedent. See Williams v.

Taylor, 

, 395 (2000) (finding mitigation investigation deficient where

“counsel did not begin to prepare for that phase of the proceeding until a week

before the trial”).

       Despite ample evidence of deficient performance, the Alabama Court of

Criminal Appeals (CCA) concluded that Downey performed reasonably. The

CCA’s decision rested on three explanations: (1) because Downey did not testify,

courts must presume he acted reasonably; (2) based on the record, Downey played


1
  The majority goes to great pains to maintain that Downey did not know about Jenkins’ abusive
childhood. This assertion is directly refuted by the record. Douglas Scofield, Jenkins’ lead
attorney, testified that Jenkins described his traumatic upbringing at meetings at which Downey
was present.
2
 It is unclear whether Downey contacted Seal and requested that he testify during the penalty
phase of trial. Given that Downey urged Scofield to conduct Seal’s direct examination because
Scofield was better acquainted with Seal, it is likely that Scofield made the arrangements.
                                              59
an active role investigating and preparing for the penalty phase of trial; and (3)

Downey’s decision to pursue a residual doubt strategy was reasonable.3 Because

each of these findings constituted an unreasonable determination of the facts or an

unreasonable application of clearly established federal law, Jenkins is entitled to

habeas relief. See 28 U.S.C. § 2254(d)(1).

         The CCA’s first rationale—presuming Downey acted reasonably because

Downey did not testify at the Rule 32 hearing—was based on both an unreasonable

determination of facts and an unreasonable application of clearly established law.

The CCA stated that “the record is virtually silent as to what actions were or were

not taken or what was or was not done by Mr. Downey at trial and why” and

therefore assumed that Downey’s actions “could have been reasonable and

strategic under the circumstances.” The majority likewise assumes Downey acted

reasonably. This conclusion is based, in large part, on Downey’s failure to testify

at the Rule 32 hearing. According to the majority, “[t]he problem for Jenkins is

that, like the state courts, this Court also does not know what Downey did or why.”

         But the record clearly illustrates Downey’s failure to investigate and overall

lack of preparation. First, Downey’s fee declarations—which the majority

concedes were “detailed”—showed no investigation of mitigating circumstances,

and no preparation for the penalty phase. Importantly, Downey’s fee declarations


3
    The majority opinion endorsed the CCA’s first and third explanations.
                                                 60
were exceptionally detailed, recounting his work in five-minute increments. The

single reference to the “mitigating” phase of trial in the declarations concerned a

meeting with Scofield that occurred only a week before trial. Other than that

vague entry, no notation indicates that Downey did anything to prepare for the

penalty phase of trial during the nearly two years he represented Jenkins.

      Second, and more persuasively, Douglas Scofield, Jenkins’ lead attorney,

explicitly testified that Downey told him that Downey had not investigated

potential mitigating evidence. Both the Alabama courts and the majority ignore

that fact and instead focus on Scofield’s testimony that, “[a]part from what he has

told me, I don’t know what he has done.” This statement, to which the majority

assigns great weight, is hardly illuminating. Of course Scofield knows only what

Downey told him. And what Downey told him was this: Downey did not

investigate potentially mitigating evidence before the penalty phase.

      In the face of this direct evidence of deficient performance, the Alabama

courts and the majority pivot to Downey’s failure to testify at the Rule 32 hearing.

Without his testimony, the majority reasons, we must assume that Downey’s

decision not to investigate was strategic and therefore his representation

reasonable. I disagree, and I have deep reservations about the practical effects of

the majority’s understanding of the law. The majority suggests (if not holds) that

the absence of testimony from an allegedly deficient attorney per se means that the


                                         61
attorney’s actions were reasonable. It is true that “counsel is strongly presumed to

have rendered adequate assistance,” 

. But a petitioner

may overcome that burden with evidence of inadequate assistance. And that

evidence may take various forms. To satisfy the burden, it is not necessary for the

allegedly deficient counsel to testify and admit wrongdoing. Nor is it necessary for

the record to reflect counsel’s “thoughts and intentions as he prepared for the

penalty phase,” as the majority seems to require. When evaluating whether a

counsel’s performance was deficient, we ask whether his performance “fell below

an objective standard of reasonableness.” Strickland, 

–88. We do not

contemplate what counsel thought or intended. We consider whether his

performance was objectively unreasonable. See 

Alabama courts

did not apply the proper standard, their conclusion was an unreasonable application

of clearly established law. See 

second reason for denying Jenkins relief was also based on an

unreasonable application of clearly established federal law. The CCA concluded

that Downey had adequately investigated and prepared for the penalty phase of

trial, emphasizing that Downey met with Jenkins on several occasions and spoke

with Jenkins’ grandmother. Based on these findings, the CCA determined that

Downey provided adequate assistance of counsel during the penalty phase. This is

an unreasonable application of clearly established law that “[a]n attorney has a


                                         62
duty to conduct a reasonable investigation, including an investigation of the

defendant’s background, for possible mitigating evidence.” Porter v. Singletary,

, 557 (11th Cir. 1994).

       As previously discussed, it is established in the record that Downey knew of

Jenkins’ horrible upbringing yet still failed to investigate potentially mitigating

evidence. “A reasonable investigation . . . should have included, at a minimum,

interviewing other family members who could corroborate the evidence of abuse

and speak to the resulting impact on [Jenkins].” 

. But

Downey did not conduct a single interview—of a family member or otherwise—in

preparation of the penalty phase.4 Because Downey did not conduct an

investigation, let alone a reasonable investigation, the CCA’s conclusion that

Downey adequately investigated potentially mitigating evidence was an

unreasonable application of clearly established law.

       The CCA’s third rationale for its decision—that Jenkins’ counsel reasonably

and strategically decided to focus on residual doubt—was both an unreasonable

application of clearly established law and an unreasonable determination of the

facts. In Williams v. Taylor, the Supreme Court held that otherwise reasonable

trial strategies cannot be justified unless counsel first conducted a constitutionally

Wagoner. But that call occurred 18 months before trial and, according to Wagoner, concerned a
request for money.

–96. And here, Downey conducted no

such investigation. It cannot be said, therefore, that Downey’s decision—if one

can even call it that—to pursue a residual doubt strategy was strategically

reasonable. See 

conclusion to the contrary was an unreasonable

application of clearly established law.

      The conclusion was likewise an unreasonable determination of the facts. On

direct appeal, the Alabama CCA noted that “[t]he evidence overwhelmingly

pointed to the guilt of the appellant.” Jenkins v. State, 

(Ala. Crim.

App. Feb. 27, 1992). Then, on appeal from Jenkins’ Rule 32 petition, the CCA

again acknowledged how “[t]he evidence establishing Jenkins’s guilt was

overwhelming.” Jenkins v. State, 

, 157 (Ala. Crim. App. Feb. 27,

2004); see also 

(“The amount of evidence incriminating Jenkins . . . was

overwhelming.”). Despite the “overwhelming” evidence of Jenkins’ guilt, the

CCA concluded that Jenkins’ counsel acted reasonably in presenting a residual

doubt defense during the penalty phase of trial. But no reasonable attorney would

employ a residual doubt strategy in the face of such overwhelming evidence. See

–33. The Alabama courts’ contrary conclusion, therefore,

was an unreasonable determination of the facts.




                                          64
   B. Prejudice

      Jenkins’ Rule 32 petition also pleaded sufficient facts to show that his

counsel’s deficient performance prejudiced his defense, satisfying the second

Strickland prong. To establish prejudice, a petitioner must show a “reasonable

probability that, but for counsel’s unprofessional errors, the result of the

proceeding would have been different.” 

. Here, the

jury voted in favor of the death penalty by the slimmest margin permitted under

Alabama law: ten votes in favor and two votes against. Jenkins need only

establish, then, “a reasonable probability that at least one juror would have struck

a different balance.” 

(emphasis added). In measuring

that probability, we “evaluate the totality of the available mitigation evidence—

both that adduced at trial, and the evidence adduced in the habeas proceeding in

reweighing it against the evidence in aggravation.” 

.

      The testimony elicited at the Rule 32 hearing was horrendous. Four family

members offered detailed, consistent testimony about Jenkins’ traumatic

childhood. The majority describes that testimony, highlighting some of the most

appalling facts elicited at the Rule 32 hearing. For example, Jenkins’ stepfather

would beat Jenkins on a semi-daily basis, would lock him in a room for hours

without food, and even made Jenkins eat his own feces. In addition to the

mitigating facts detailed by the majority, the following came to light during the


                                          65
Rule 32 hearing. Jenkins’ mother had an affair while her husband, Jenkins’

stepfather, was in prison. When Jenkins’ stepfather was released, he took out his

frustrations about the affair on Jenkins. Because Jenkins’ biological father was

Jenkins’ stepfather referred to Jenkins in demeaning names like “Mexican trash,”

and “Puerto Rican puke.” The stepfather also called him “piece of shit” and

“bastard.”

       The Rule 32 testimony also detailed the alcohol substance abuse, drug

addiction, and incessant domestic violence that surrounded Jenkins’ childhood.

And, most shockingly, the testimony described how Jenkins’ grandfather sexually

abused Jenkins when Jenkins was just four years old. As a result of that sexual

abuse, Jenkins, suffered bladder and bowel movement issues. Jenkins’

incontinence became a trigger for his stepfather: when Jenkins had an accident, his

stepfather would beat him or subject him to severe degradation. For example,

Jenkins’ stepfather would hang Jenkins’ soiled sheets in the front yard for all the

neighbors to see, make Jenkins wear his soiled clothes on his head, and, most

disturbingly, make Jenkins eat his own feces. The only way to escape the abuse

was by running away. So, by age twelve, Jenkins lived on the streets.5



5
  The CCA found parts of the family members’ testimony not credible, though it did not
explicitly discredit testimony describing some of the worst abuse. Given the grotesque nature of
the family members’ testimony, and the fact that their testimony was consistent, there is
reasonable probability that at least one more juror would have been compelled to vote against a
death sentence.
                                               66
      Jenkins also introduced medical, school, and juvenile court records from his

childhood, which shed further light on his difficult childhood and intellectual

deficiencies. Juvenile records show Jenkins as “an emotionally disturbed child”

with “psychological problems” and expressed “grave concerns for the emotional

will being of this adolescent”. Moreover, two psychologists testified about

Jenkins’ history of psychological trauma stemming from his childhood abuse—

weighty evidence that is not even considered in the majority’s discussion. Finally,

two prison guards testified that Jenkins was the ideal prisoner during pretrial

detention. One of the guards even described Jenkins as the best inmate he had

every supervised.

      Given this compelling mitigating evidence, it is not difficult to conclude that

Jenkins established “a reasonable probability that at least one juror would have

struck a different balance” between life and death. 

; see

also 

(listing several factors that support a prejudice

finding, including (1) evidence of impaired intellectual functioning; (2) evidence of

childhood sexual abuse; and (3) the fact that the jury voted only 10–2 in

recommending a death sentence).

                            I.     Evidentiary Hearing

      Jenkins also argues that he is entitled to habeas relief under Atkins v.

Virginia, 

(2002). He contends that he satisfies the three requirements


                                          67
necessary to establish intellectual disability—(1) subaverage intellectual

functioning; (2) deficits in adaptive behavior; and (3) onset before the age of 18,

see Ex parte Perkins, 

, 456 (Ala. 2002)—thus, exempting him from

implementation of the death penalty. Alternatively, Jenkins argues that we should

remand for an evidentiary hearing on the Atkins issue.

      The majority dismisses each argument. First, it concludes that the CCA did

not act unreasonably in concluding that Jenkins failed to satisfy any of the Perkins

prongs. Second, it determines that Jenkins is not entitled to an evidentiary hearing

because he “did not diligently attempt to develop the factual basis for this claim in

the state court.” I disagree.

      First, it is not possible to undergo a substantive Atkins analysis based on the

record before us. For one, the CCA’s evaluation of Jenkins’ Atkins claim was a

mere three sentences. And, more significantly, Jenkins never had an opportunity to

present evidence on his Atkins claim. To deny Jenkins’ claim, therefore, the

majority relies on evidence from unrelated parts of the record. Such an approach is

improper because, “[p]rior to Atkins, [the petitioner] could not have been expected

to necessarily present evidence sufficient to support an Atkins claim because such

evidence constituted a double edged sword.” Burgess v. Comm’r, Ala. Dep’t of

Corr., 

, 1320 (11th Cir. 2013) (internal citation omitted). The

evidence was a double-edged sword, we explained, because prior to Atkins,


                                          68
evidence of intellectual disability could suggest that a defendant would be

dangerous in the future; therefore, “a defendant could reasonably decide not to

highlight his mental retardation.” 

For that reason, courts should not

rely on pre-Atkins evidence—evidence that was presented in a wholly distinct

context—to support a finding that a petitioner is not intellectually disabled. So,

here, instead of attempting to make a medical diagnosis based on an insufficient

record, we should remand for an evidentiary hearing. The majority refuses to do

so, reasoning that “Jenkins did not diligently attempt to present his Atkins claim in

the state courts.” I disagree.

      “[I]f the petitioner was diligent in developing the record in the state habeas

proceedings, ‘a federal court may grant an evidentiary hearing without further

regard for the provisions of § 2254(3)(2).” 

(citation

omitted). “‘Diligence [for purposes of § 2254(d)] depends on whether the prisoner

made a reasonable attempt, in light of the information available at the time, to

investigate and pursue claims in state court,’ and ‘will require in the usual case that

prisoner, at a minimum, seek an evidentiary hearing in state court.’” 

, 529 U.S. at 435 (emphasis added)).

      The majority concludes that Jenkins failed to diligently pursue his Atkins

claim in state court. But again, based on binding precedent and the record, I must

part company with the majority. In conducting its analysis, the majority does not


                                          69
adequately consider whether Jenkins “made a reasonable attempt, in light of the

circumstances available at the time, to investigate and pursue claims in state

court.” 

(quoting 

). Specifically, the

majority did not consider the unusual procedural posture of Jenkins’ claim.

      The Supreme Court issued Atkins v. Virginia while Jenkins’ petition for

post-conviction collateral relief was pending before the CCA. The CCA, therefore,

requested supplemental briefing on the effect, if any, Atkins had on Jenkins’

petition. At that point, neither the Alabama Supreme Court nor the Alabama

legislature had interpreted the groundbreaking case, making Jenkins’ counsel’s

next step unclear. Jenkins’ counsel nonetheless made a reasonable attempt to

pursue Jenkins’ Atkins claim—he requested that the CCA “vacate his death

sentence and remand the case back to the lower court for further proceedings.”

The request appears even more reasonable when considered alongside procedurally

analogous cases decided around the same time.

      At the time Jenkins’ counsel was preparing the supplemental briefing, there

had been three other post-conviction petitions for relief that shared Jenkins’

unusual procedural posture. See Clemons v. State, 

(Ala. Crim. App.

Aug. 29, 2003); Wood v. State, 

(Ala. Crim. App. Apr. 25, 2003);

Tarver v. State, 

(Ala. Crim. App. Feb. 27, 2004). These three cases

are similar to Jenkins’ petition in that (1) the petitioners were sentenced to death,


                                          70
(2) the petitioners filed Rule 32 petitions, (3) their Rule 32 petitions were

dismissed at the trial court level, (4) while their appeals before the CCA were

pending, Atkins was decided, and (5) given the Atkins decision, each petitioner

submitted supplemental briefing. In their supplemental briefs, Clemons, Wood,

and Tarver each argued that he was intellectually disabled under Atkins and thus it

would be unconstitutional to execute him. None of the petitioners asked for an

evidentiary hearing on their Atkins claim or requested a remand for further

proceedings. Despite the lack of request for a hearing, the CCA remanded for an

evidentiary hearing in each case.

      With these cases in mind, it would have been reasonable for Jenkins to think

that broadly stating his Atkins claim would constitute “diligent” pursuit of his

claim. Nonetheless, Jenkins did more than these other petitioners: he specifically

requested that the CCA “vacate his death sentence and remand the case back to the

lower court for further proceedings.” Given “the information available at the

time,” Jenkins’ made a “reasonable attempt” to pursue his claims.

      I also cannot come to terms with the majority’s ultimate conclusion. The

majority determines that Jenkins did not act diligently in pursuing his Atkins claim

because “[t]he record clearly shows that Jenkins did not [seek an evidentiary

hearing].” But Jenkins did ask the CCA to “remand his case for further

proceedings.” And, in Alabama, post-conviction relief petitioners with factually


                                          71
sufficient claims are entitled to an evidentiary hearing. Ala. R. Crim. P. 32.9. So,

if the CCA had granted Jenkins’ request to remand “for further proceedings,”

Jenkins would have received an evidentiary hearing. Jenkins’ request that the

CCA “remand for further proceedings,” then, was effectively equivalent to a

request for an evidentiary hearing. The majority’s superficial conclusion to the

contrary misses the point.

                                 II.   Conclusion

      Jenkins’ Rule 32 evidentiary hearing spanned three days. Four family

members testified about his horrific upbringing. Two psychiatrists testified about

how that upbringing affected Jenkins as an adult. Two prison guards testified

about Jenkins’ exemplary behavior while in pretrial detention. And one friend

testified about Jenkins’ character. Evidence introduced also documented Jenkins’

academic failings and his juvenile record. In short, Jenkins presented an

abundance of compelling mitigating evidence. But the jury never heard any of that

evidence. Downey failed to introduce it at the penalty phase. In fact, Downey

failed to investigate any mitigating evidence whatsoever. Downey’s failures

cannot be attributed to strategic decisions. Nor can they be called reasonable. His

performance can only be described as deficient. And that deficient performance

was surely prejudicial—there is more than a reasonable probability that the

horrifying and detailed Rule 32 testimony would have persuaded one juror to vote


                                         72
against sentencing Jenkins to death. Jenkins is therefore entitled to habeas relief

on his ineffective assistance of counsel claim.

      Jenkins is also entitled to a hearing on his Atkins claim. Though Jenkins

presented ample mitigating evidence at the Rule 32 hearing, he never had an

opportunity to present evidence concerning (1) his intellectual functioning, (2) his

adaptive deficits, or (3) whether his potential intellectual disability manifested

before Jenkins reached 18—the three requirements necessary to establish

intellectual disability and thus exempt an individual from a death sentence. The

CCA nonetheless decided to evaluate Jenkins’ Atkins claim, apparently believing

that the record, which included no direct evidence concerning whether Jenkins was

intellectually disabled, was sufficient to resolve the complex medical issue. In just

three sentences, the CCA arrived at a diagnosis: not intellectually disabled.

      Despite the insufficient factual record, the majority declines to remand with

instructions to conduct an evidentiary hearing—what I view as the proper

recourse—because Jenkins did not use the phrase “evidentiary hearing” when

requesting further proceedings on his Atkins claim in the Alabama courts. Such a

rigid understanding of the standard should not bar a death row petitioner from

bringing a constitutional, and potentially lifesaving, claim. I therefore dissent.
