WIGGINS, Justice.

A juvenile offender convicted of first-degree murder appeals his resentencing to life in prison without the possibility of parole. In this appeal, we determine the factors a court must use when it sentences a juvenile offender for first-degree murder. Because the district court did not have the benefit of this decision when it sentenced the juvenile, we vacate the sentence and remand for resentencing. We do not reach the issue as to whether a sentence of life in prison without parole categorically violates the Iowa Constitution's prohibition against cruel and unusual punishment, because we are remanding the case for resentencing.

I. Background Facts and Proceedings.

On August 23, 2008, Damion Seats, who was seventeen years old at the time, went to a party at a friend's house in Mason City. While at the party, Seats's friend, Andre Wells revealed he had a handgun in his pocket. In the early morning hours of August 24, Seats and Wells convinced another friend, Jamie McFarland, to give them and two acquaintances a ride from the party to Reuben Ramirez's house.

Earlier that month, Seats initiated a fight with Ramirez at Ramirez's house. During the fight, Seats hit Ramirez on the head with a brick. On the evening of the party, Seats was concerned that Ramirez would report the brick incident to the police. Before leaving for Ramirez's house, Seats and Wells placed the loaded gun in the trunk of the car.

When the vehicle arrived at Ramirez's house, Seats instructed McFarland to park in the alley. Seats and Wells then tied t-shirts around their faces, retrieved the loaded handgun from the trunk, and entered the residence through a back door. When Seats and Wells entered the house Ramirez was not home, but Isidoro Cervantes Erreguin, who stayed with Ramirez at times, and Cervantes's brother were. Both were in the living room, asleep on different couches. Seats approached the living room couch where Cervantes was sleeping and shot him five times. Four of the bullets entered Cervantes's back and the fifth entered his chest. After Seats and Wells fled, paramedics arrived at Ramirez's house and attempted to perform CPR on Cervantes. The paramedics declared Cervantes dead at the scene.

Seats and Wells returned to McFarland's waiting car. After the group left Ramirez's house, Seats wrapped the handgun in a shirt and hid it under some bushes near his brother's apartment.

On the afternoon of August 24, Seats came to the police department and asked to speak with investigators. Seats met with the case agent assigned to lead the murder investigation, Division of Criminal Investigation Special Agent Chris Callaway. Seats had reportedly heard from his friends that the police mentioned his name as a possible suspect in Cervantes's murder. Seats stated he had come to the police station voluntarily in order to clear his name. Special Agent Callaway interviewed Seats for about two hours.

Seats recounted being at a friend's party on the night of the 23rd and said he stayed there until about 3:00 a.m. on the 24th. Seats acknowledged that after the party, he, Wells, and two acquaintances got a ride from McFarland. However, according to Seats, McFarland took the two acquaintances home, then dropped off Wells in a Walmart parking lot where Wells planned to meet up with another acquaintance. Seats told Special Agent Callaway that McFarland then drove him to another friend's house where he stayed the night. Seats stated he arrived at this friend's house around 4:00 a.m. on August 24 and slept there until about 11:00 a.m. He denied any involvement in the murder. The police permitted Seats to leave the station after the interview, but they continued to conduct surveillance on Seats.

While Special Agent Callaway was interviewing Seats, Wells came to the police department and turned over the gun Seats had hidden in the bushes. Based on Wells's version of events, the police arrested Seats that evening. The police brought Seats back to the station for another interview, this time Special Agent Callaway and Special Agent in Charge Jeff Jacobson were present and recorded the interview.

After Mirandizing Seats, the agents informed him they had recovered the gun and asked for his version of events. Seats initially continued to deny any involvement in the murder, but then told investigators he would tell them anything they wanted to know if he could speak to his girlfriend. The police allowed Seats to speak to both his girlfriend and his mother during the interview. When his mother asked him why he had shot Cervantes, he stated that he had intended to kill Ramirez to keep him from pressing charges. He went on to say, "I wasn't thinking of anybody this would've hurt if I got caught; I didn't think I was gonna get caught...." After the phone call to his mother, Seats drew a diagram of Ramirez's house and indicated where he entered the house, where the occupants were sleeping, and where he stood when he shot Cervantes. Seats also told investigators he felt remorse for shooting an innocent man.

On September 9, the county attorney filed a trial information charging Seats, Wells, and McFarland jointly with first-degree murder and first-degree burglary. See Iowa Code §§ 707.1, .2; id. §§ 713.1,.3 (2009).

Notwithstanding his confession, Seats pled not guilty and went to trial separately from the other defendants. The jury found Seats guilty of both first-degree murder and first-degree burglary.

On October 26, 2009, as required by Iowa law, the court sentenced Seats to life without parole on the murder charge. See Iowa Code § 902.1 ("Upon a ... verdict of guilty, ... the court shall enter a judgment of conviction and shall commit the defendant into the custody of the director of the Iowa department of corrections for the rest of the defendant's life.... [A] person convicted of a class `A' felony shall not be released on parole unless the governor commutes the sentence to a term of years."). It also sentenced Seats concurrently to twenty-five years imprisonment on the burglary conviction. See id. § 902.9(2). The court of appeals affirmed his convictions.

On August 17, 2011, Seats filed a motion to correct an illegal sentence. At that time, Miller v. Alabama, 567 U.S. ___, 132 S.Ct. 2455, 183 L.Ed.2d 407 (2012), was pending before the United States Supreme Court. The district court continued the hearing on Seats's motion until the Supreme Court rendered a decision. Shortly after Miller was decided, but before the trial court heard Seats's motion, Iowa's Governor commuted the sentences of all juveniles previously convicted of first-degree murder to a life sentence with the possibility of parole after sixty years. Seats requested and the district court granted a further postponement until we had decided a number of pending cases concerning this commutation and other aspects of juvenile sentencing.

On August 16, 2013, in State v. Ragland, we held the Governor's blanket commutation of the juveniles' life without parole sentences to life with eligibility for parole after sixty years did not affect the constitutional requirement that the district court proceed with an individualized hearing as required by Miller. See State v. Ragland, 836 N.W.2d 107, 121-22 (Iowa 2013). The district court scheduled an individualized resentencing hearing for Seats after the filing of the Ragland opinion.

In 2013, the court ordered a new presentence investigation report, which Barbara Brandt, a Mason City parole officer, prepared and filed. The report noted Seats had a difficult childhood, including a lack of adult supervision and exposure to gang violence at a very early age. It also indicated Seats had a history of homelessness and alcohol and drug abuse. The report indicated Seats had not graduated high school or completed his GED, but he had completed a literacy program while incarcerated. The report detailed Seats's juvenile criminal history. Seats told the parole officer that the majority of the people in his life had been negative influences, although some friends and associates in Mason City were positive influences. According to the report, Seats told the parole officer "[t]he difference between defendant and his co-defendants was that they had supportive family members and that wasn't the case for him."

Additionally, the report noted the prison had disciplined Seats ten times, including for fighting, for possession of intoxicants, and twice for theft and unauthorized possession. Finally, the report indicated Seats held a job during his time in prison, but as of October 29, 2013, he was not employed due to his status. However, the report stated his case manager anticipated Seats would be eligible to work again in November 2013. The report did not make a sentencing recommendation because the court had previously sentenced Seats.

The court held a resentencing hearing on November 22. The court described the purpose of the proceeding as follows:

Seats testified at the hearing about his childhood. He explained his father stopped living with the family when Seats was four years old and Seats had little contact with his father growing up. Seats's father was a drug addict and used drugs when he was around Seats and his siblings. At this time, Seats has no relationship with his father.

Seats told the court as a young boy he considered his uncle a role model, even though his uncle had been in prison for drugs and attempted murder. Gang members murdered Seats's uncle in front of Seats when he was seven years old.

Seats's mother has lived in Chicago since 2006, when she returned to take care of Seats's brother who was shot in a gang incident. Prior to her return to Chicago, Seats lived with his mother, moving abruptly between Virginia, Illinois, Wisconsin, and Iowa.

After his father left, Seats's mother began a relationship with Greg, a gang member in Chicago. Greg physically abused his mother in front of Seats and his siblings. Seats remembered Greg hitting his mother in the head with a hammer.

By the time Seats was ten years old, Seats's mother had a new boyfriend, Keith, who was abusive to Seats's mother and all of the children. Keith was physically, verbally, and emotionally abusive, using household items to hit the children. Seats recalled all the children sleeping under their beds to avoid Keith's beatings. Further, while she was with Keith, Seats's mother also became abusive towards the children and at one point Seats's grandmother removed the children from their home for a few months to keep them safe. Seats reported he stayed out all night in Chicago to avoid the violence while Keith was in the home.

Seats has two brothers and one sister. Both of Seats's brothers have been imprisoned at one time for drugs and violent crimes. Seats's sister also has a history of drug use and criminal charges.

Seats was involved in gangs since the age of thirteen. When his mother moved back to Chicago in 2006 Seats stayed in Mason City, living with his brother who was approximately twenty years old. His brother allowed Seats to use cocaine, ecstasy, marijuana, and alcohol. By fifteen years old Seats was essentially homeless, staying with friends and gang members. At the age of sixteen, a rival gang shot Seats three times to get back at Seats's brother, who was in prison at the time. Seats also sold drugs as a teenager.

Seats stated he had received counseling and treatment through the juvenile court system but continued to commit the offenses noted in his juvenile record. Seats testified that some time before Cervantes's murder he had worked for two weeks at a grocery store but decided he did not want to do that and quit. Seats also continued to deny murdering Cervantes. As he put it, "[I]t didn't happen." Seats informed the court he was taking steps to better himself, such as being more patient and trying to control his drug and alcohol addictions. He testified he would take full advantage of opportunities to finish his GED and learn a job if they were made available to him.

At the sentencing hearing, Seats asked for immediate parole eligibility and for the court to "rely on the parole board to determine when [he] or anybody in his position has developed to the point where he is no longer a threat to society and would be a productive member of society." He also urged the court to impose a term-of-years sentence, rather than a life term, because it would allow Seats to earn good time on his sentence and "the good time is an incentive for him to accomplish the very things that we are talking about right now... to get the parole that he would be seeking."

The State argued Seats's case warranted a sentence of life without parole. It urged the concern for juvenile brain development is less in a case where the offender, like Seats, was just months away from his eighteenth birthday. It maintained that the nature of Seats's crime and the surrounding circumstances did not support a finding that it was the result of youthful incompetency. Finally, the State pointed to Seats's extensive juvenile record, his disciplinary violations in prison, and the fact that he still denied responsibility for the murder as evidence that he was not amenable to rehabilitation.

At the conclusion of the hearing, the district court indicated it would take the weekend to consider the testimony and evidence before rendering a decision on Seats's resentencing. Four days later, the court issued its decision on the record. The court stated it was conducting a resentencing based on statutory factors and the factors set forth in Miller:

Applying these considerations, the court stated this was one of the "unusual" cases warranting life without parole. The court addressed Seats's personal characteristics and potential for reform, using his childhood circumstances, the negative family influences in his life, and his lack of a stable support system as a factor against him:

The court went on to discuss the nature of Seats's crime. The court acknowledged Seats's troubled youth, but concluded it did not outweigh the serious nature of Seats's crime and behavior:

Ultimately, the court granted Seats's motion to correct the illegal sentence "[t]o the extent the previous sentence was imposed without individualized consideration of the circumstances." It otherwise denied the motion and upheld Seats's sentence of life with parole eligibility after sixty years as commuted by the governor.

Seats appealed, and we retained the appeal.

II. Issues.

The defendant raises three issues on appeal. First, whether the district court's imposition of life in prison without the possibility of parole categorically violates article I, section 17 of the Iowa Constitution, which prohibits cruel and unusual punishment. Next, if it does not, does the sentence imposed by the court upholding the Governor's commutation of his original sentence to sixty years before he is eligible for parole violate article I, section 17 of the Iowa Constitution. Third, whether the sentence of life without the possibility of parole, even after discarding the Governor's commutation, as applied to the facts of this case constitute cruel and unusual punishment. We can resolve this appeal by addressing the last issue.

III. Standard of Review.

We have expressed three different standards of review when a defendant challenges his or her sentence on appeal. We use the abuse of discretion standard if the sentence is within the statutory limits. When reviewing a sentence for an abuse of discretion, we have said:

State v. Formaro, 638 N.W.2d 720, 724-25 (Iowa 2002) (citations omitted). In other words, a district court did not abuse its discretion if the evidence supports the sentence. State v. Valin, 724 N.W.2d 440, 445 (Iowa 2006).

We also review sentences for correction of errors at law. We do so when the defendant challenges the legality of a sentence on nonconstitutional grounds. Id. at 443-44. We use the correction of errors at law standard when the statute does not authorize the sentence. State v. Freeman, 705 N.W.2d 286, 287 (Iowa 2005).

More recently, we have begun to decide cases involving constitutional attacks on the validity of a sentence. See Ragland, 836 N.W.2d at 109-10 (examining whether a defendant's sentence amounts to cruel and unusual punishment under the Iowa Constitution); State v. Pearson, 836 N.W.2d 88, 89 (Iowa 2013) (same); State v. Null, 836 N.W.2d 41, 45 (Iowa 2013) (same); State v. Bruegger, 773 N.W.2d 862, 866, 886 n. 9 (Iowa 2009) (same). When a defendant attacks the constitutionality of a sentence, our review is de novo. Ragland, 836 N.W.2d at 113; Pearson, 836 N.W.2d at 94; Null, 836 N.W.2d at 48; Bruegger, 773 N.W.2d at 869.

Therefore, we apply the de novo standard to this appeal because Seats is attacking his sentence on constitutional grounds.

IV. Analysis.

The United States Supreme Court decided that although a sentencing court has the discretion to sentence a juvenile offender who commits murder to the harshest penalty possible — life in prison without the possibility of parole — such a sentence should be uncommon. Miller, 567 U.S. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 424. Here, the district court sentenced Seats to the harshest sentence. Seats argues this is not the uncommon circumstance to do so. To analyze Seats's argument, we review the Supreme Court cases dealing with juvenile sentencing as well as recent cases under the Iowa Constitution dealing with cruel and unusual punishment in the juvenile context.

A. United States Supreme Court Jurisprudence. Miller is the most recent Supreme Court opinion dealing with the sentencing of juvenile offenders to life in prison without parole when the juvenile commits a murder. Before Miller, the Court decided Roper v. Simmons, 543 U.S. 551, 125 S.Ct. 1183, 161 L.Ed.2d 1 (2005) and Graham v. Florida, 560 U.S. 48, 130 S.Ct. 2011, 176 L.Ed.2d 825 (2010).

In Roper, the Supreme Court held executing juveniles who had committed capital crimes violated the Eighth and Fourteenth Amendments of the United States Constitution. 543 U.S. at 578, 125 S.Ct. at 1200, 161 L.Ed.2d at 28. The seventeen-year-old defendant in Roper took a woman from her home, tied her up — with duct tape covering her head and wire binding her extremities — and threw her into a river to drown. Id. at 556-57, 125 S.Ct. at 1187-88, 161 L.Ed.2d at 13.

In support of its holding, the Court recognized three general differences between juveniles and adults that "render suspect any conclusion that a juvenile falls among the worst offenders." Id. at 569-70, 125 S.Ct. at 1195, 161 L.Ed.2d at 21-22. First, juveniles have "`[a] lack of maturity and an underdeveloped sense of responsibility.'" Id. at 569, 125 S.Ct. at 1195, 161 L.Ed.2d at 21 (quoting Johnson v. Texas, 509 U.S. 350, 367, 113 S.Ct. 2658, 2668, 125 L.Ed.2d 290, 306 (1993)). The Court recognized these characteristics "`often result in impetuous and ill-considered actions and decisions.'" Id. (quoting Johnson, 509 U.S. at 367, 113 S.Ct. at 2668, 125 L.Ed.2d at 306). Second, juveniles are more susceptible than adults are to "negative influences and outside pressures" and "juveniles have less control, or less experience with control, over their own environment." Id. at 569, 125 S.Ct. at 1195, 161 L.Ed.2d at 22. Third, a juvenile's personality and character traits are still forming, and are not as fixed as an adult's personality and character traits are. Id. at 570, 125 S.Ct. at 1195, 161 L.Ed.2d at 22. As a result of these differences, there is a greater possibility "that a minor's character deficiencies will be reformed" and "`the impetuousness and recklessness that may dominate in younger years can subside.'" Id. at 570, 125 S.Ct. at 1195-96, 161 L.Ed.2d at 22 (quoting Johnson, 509 U.S. at 368, 113 S.Ct. at 2668, 125 L.Ed.2d at 306).

Next, in Graham, the Court held the Eighth Amendment prohibits states from sentencing juveniles who did not commit homicide to life in prison without parole, and the states sentencing these juveniles to a life sentence must provide a "realistic opportunity to obtain release before the end of that term." 560 U.S. at 82, 130 S.Ct. at 2034, 176 L.Ed.2d at 850. The defendant in Graham committed a number of criminal offenses including armed burglary, armed robbery, and fleeing from police. Id. at 53-55, 130 S.Ct. at 2018-19, 176 L.Ed.2d at 832-33.

The Court relied upon the reasoning articulated in Roper regarding juveniles' underdeveloped sense of responsibility and lack of maturity to demonstrate that "[a] juvenile is not absolved of responsibility for his actions, but his transgression `is not as morally reprehensible as that of an adult.'" Id. at 68, 130 S.Ct. at 2026, 176 L.Ed.2d at 841 (quoting Thompson v. Oklahoma, 487 U.S. 815, 835, 108 S.Ct. 2687, 2699, 101 L.Ed.2d 702, 719 (1988) (plurality opinion)). The Court went on to recognize "developments in psychology and brain science continue to show fundamental differences between juvenile and adult minds ... [and the] parts of the brain involved in behavior control continue to mature through late adolescence." Id. The Court also identified that juveniles are more capable of changing their character and reforming than adults are. Id. at 68, 130 S.Ct. at 2026-27, 176 L.Ed.2d at 841-42. The Court noted for juveniles a life sentence without parole

Id. at 70, 130 S.Ct. at 2027, 176 L.Ed.2d at 842 (internal quotation marks omitted). Further, the Court in both Graham and Roper determined none of the penological justifications for sentencing — retribution, deterrence, incapacitation, or rehabilitation — are served when imposing either of these sentences on juveniles. Graham, 560 U.S. at 71-74, 130 S.Ct. at 2028-30, 176 L.Ed.2d at 843-45; Roper, 543 U.S. at 571-72, 125 S.Ct. at 1196-97, 161 L.Ed.2d at 23.

In Miller, the Court decided it did not have to reach a categorical challenge to a sentence of life in prison without parole for a juvenile who commits murder as it did in Roper and Graham. Miller, 567 U.S. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 424. The Court did not reach the categorical challenge because its holding was sufficient to decide the cases before the Court in Miller. Id. In not addressing the categorical challenge, the Court made it clear that the "appropriate occasions for sentencing juveniles to this harshest possible penalty, [life in prison without the possibility of parole,] will be uncommon." Id. The Miller Court required judges or juries "must have the opportunity to consider mitigating circumstances before imposing the harshest possible penalty for juveniles." Id. at ___, 132 S.Ct. at 2475, 183 L.Ed.2d at 430.

In reaching this decision, the Court built on its jurisprudence espoused in Roper and Graham. In Miller, the court reiterated there is a significant constitutional difference between children and adults that "diminish the penological justifications for imposing the harshest sentences on juvenile offenders, even when they commit terrible crimes." Id. at ___, 132 S.Ct. at 2465, 183 L.Ed.2d at 419. This is

Id. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 424 (quoting Roper, 543 U.S. at 573, 125 S.Ct. at 1197, 161 L.Ed.2d at 24).

B. Application of Supreme Court Jurisprudence to Juveniles in Iowa. We have previously discussed the role Roper, Graham, and Miller play in sentencing a juvenile subject to a mandatory minimum sentence for a nonhomicide crime. Null, 836 N.W.2d at 74-75. In a case in which the court has discretion to sentence a juvenile to life in prison without the possibility of parole, Miller and Null require the sentencing judge to consider the following factors before sentencing a juvenile to life in prison without the possibility of parole.

First, the court must start with the Supreme Court's pronouncement that sentencing a juvenile to life in prison without the possibility of parole should be rare and uncommon. Miller, 567 U.S. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 424; Null, 836 N.W.2d at 75. Thus, the presumption for any sentencing judge is that the judge should sentence juveniles to life in prison with the possibility of parole for murder unless the other factors require a different sentence.

Second, the sentencing judge must recognize that "children are constitutionally different from adults." Miller, 567 U.S. at ___, 132 S.Ct. at 2464, 183 L.Ed.2d at 418. We have explained, "The constitutional difference arises from a juvenile's lack of maturity, underdeveloped sense of responsibility, vulnerability to peer pressure, and the less fixed nature of the juvenile's character." Null, 836 N.W.2d at 74; see also Miller, 567 U.S. at ___, 132 S.Ct. at 2464, 183 L.Ed.2d at 418.

In sentencing the juvenile offender, the court must take in account any information in the record regarding "the family and home environment that surrounds him — and from which he cannot usually extricate himself — no matter how brutal or dysfunctional." Miller, 567 U.S. at ___, 132 S.Ct. at 2468, 183 L.Ed.2d at 423. In examining the "family and home environment," the judge shall consider any information regarding childhood abuse, parental neglect, personal and family drug or alcohol abuse, prior exposure to violence, lack of parental supervision, lack of an adequate education, and the juvenile's susceptibility to psychological or emotional damage. People v. Gutierrez, 58 Cal.4th 1354, 171 Cal.Rptr.3d 421, 324 P.3d 245, 268-69 (2014). The sentencing judge should consider these family and home environment vulnerabilities together with the juvenile's lack of maturity, underdeveloped sense of responsibility, vulnerability to peer pressure as mitigating, not aggravating factors. Miller, 567 U.S. at ___, 132 S.Ct. at 2467-69, 183 L.Ed.2d at 422-24; Null, 836 N.W.2d at 74-75.

Third, the sentencing judge must consider "the circumstances of the homicide offense, including the extent of [the juvenile's] participation in the conduct and the way familial and peer pressures may have affected him." Miller, 567 U.S. at ___, 132 S.Ct. at 2468, 183 L.Ed.2d at 423. One of the circumstances the sentencing judge needs to consider is whether substance abuse played a role in the juvenile's commission of the crime. Id. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 423.

Finally, the sentencing judge must take into consideration that "[j]uveniles are more capable of change than are adults" and that as a result, "their actions are less likely to be evidence of `irretrievably depraved character.'" Graham, 560 U.S. at 68, 130 S.Ct. at 2026, 176 L.Ed.2d at 841 (quoting Roper, 543 U.S. at 570, 125 S.Ct. at 1195, 161 L.Ed.2d at 22). "[M]ost juveniles who engage in criminal activity are not destined to become lifelong criminals." Null, 836 N.W.2d at 75; see also Graham, 560 U.S. at 68, 130 S.Ct. at 2026, 176 L.Ed.2d at 841; Roper, 543 U.S. at 570, 125 S.Ct. at 1195-96, 161 L.Ed.2d at 22. As we said in Null, a case decided under the Iowa Constitution, "incorrigibility is inconsistent with youth, care should be taken to avoid an irrevocable judgment about [an offender's] value and place in society." Null, 836 N.W.2d at 75 (internal quotation marks omitted). It is very difficult for a judge to distinguish between "`the juvenile offender whose crime reflects unfortunate yet transient immaturity, and the rare juvenile offender whose crime reflects irreparable corruption.'" Miller, 567 U.S. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 424 (quoting Roper, 543 U.S. at 573, 125 S.Ct. at 1193, 161 L.Ed.2d at 24). The sentencing judge should only sentence those juveniles to life in prison without the possibility of parole whose crime reflects irreparable corruption.

We note the district court emphasized that Seats was a seventeen-year-old at the time the crime was committed. We recognize that in Roper, the line between being a juvenile and an adult was drawn for cruel and unusual punishment purposes at eighteen years of age. See Roper, 543 U.S. at 574, 125 S.Ct. at 1197-98, 161 L.Ed.2d at 24-25. Yet, as we stated in Null, current science demonstrates that the human brain continues to develop into the early twenties. 836 N.W.2d at 55. As stated by two leading scholars in adolescent development and the law, "[t]he research clarifies that substantial psychological maturation takes place in middle and late adolescence and even into early adulthood." Elizabeth S. Scott & Lawrence Steinberg, Rethinking Juvenile Justice 60 (2008). Thus, Scott and Steinberg emphasize that "adolescents, even at age sixteen and seventeen, are immature in their psychosocial and emotional development, and this likely affects their decisions about involvement in crime in ways that distinguish them from adults." Id. at 131. In light of the science, the fact that a defendant is nearing the age of eighteen does not undermine the teachings of Miller and Null.

We must be cognizant of the fact that a sentence of life in prison without the possibility of parole for a juvenile is the equivalent of the death penalty for juveniles. As Graham so aptly observed,

Graham, 560 U.S. at 79, 130 S.Ct. at 2032, 176 L.Ed.2d at 848.

Even if the judge sentences the juvenile to life in prison with parole, it does not mean the parole board will release the juvenile from prison. Once the court sentences a juvenile to life in prison with the possibility of parole, the decision to release the juvenile is up to the parole board. Iowa Code § 904A.4 (2015). If the parole board does not find the juvenile is a candidate for release, the juvenile may well end up serving his or her entire life in prison.

In Null, we found when a judge sentences a juvenile to a mandatory minimum sentence, the judge must state his or her reasons on the record for imposing such a sentence. Null, 836 N.W.2d at 71, 74. Likewise, if the sentencing judge believes the information in the record rebuts the presumption to sentence a juvenile to life in prison with the possibility of parole and the case is the rare and uncommon case requiring the judge to sentence the juvenile to life in prison without the possibility of parole, the judge must make specific findings of fact discussing why the record rebuts the presumption. "In making such findings, the district court must go beyond a mere recitation of the nature of the crime, which the Supreme Court has cautioned cannot overwhelm the analysis in the context of juvenile sentencing." Id. at 74-75.

C. Application of Supreme Court Jurisprudence to Seats. On our de novo review, we note the district did not consider the factors a court must consider before sentencing a juvenile to life in prison without the possibility of parole. Factually, the district court appeared to use Seats's family and home environment vulnerabilities together with his lack of maturity, underdeveloped sense of responsibility, and vulnerability to peer pressure as aggravating, not mitigating factors.

At the time of sentencing, the district court did not have the benefit of this decision setting forth the factors the court must use and the requirements the court needs to sentence a juvenile convicted of first-degree murder. When this happens, the proper remedy is to remand the case back to the district court to consider the matter consistent with our holding in this opinion. State v. Hildebrand, 280 N.W.2d 393, 397 (Iowa 1979).

Additionally, we need not reach the issue as to whether sentencing a juvenile to life in prison without the possibility of parole categorically violates the Iowa Constitution's prohibition on cruel and unusual punishment because we are sending this case back to the district court for resentencing. Upon resentencing, if the district court finds this is the rare and uncommon case requiring it to sentence Seats to life in prison without the possibility of parole, Seats can appeal his sentence as contrary to Miller. In that appeal, he can make the additional claim that his sentence of life in prison without the possibility of parole categorically violates the Iowa Constitution's prohibition on cruel and unusual punishment.

V. Summary and Disposition.

There is no question that juveniles who commit vicious murders deserve severe punishment. However, we cannot lose sight of the fact that juveniles are different from adults due to a juvenile's lack of maturity, underdeveloped sense of responsibility, vulnerability to peer pressure, and the less fixed nature of the juvenile's character. The question the court must answer at the time of sentencing is whether the juvenile is irreparably corrupt, beyond rehabilitation, and thus unfit ever to reenter society, notwithstanding the juvenile's diminished responsibility and greater capacity for reform that ordinarily distinguishes juveniles from adults. Therefore, we must remand this case for resentencing consistent with this opinion.

DISTRICT COURT SENTENCE VACATED AND CASE REMANDED WITH INSTRUCTIONS.

CADY, C.J., and HECHT and APPEL, JJ., join this opinion. HECHT, J., files a separate concurring opinion. MANSFIELD, J., files a dissenting opinion in which WATERMAN and ZAGER, JJ., join.

HECHT, Justice (concurring specially).

"[C]hildren are constitutionally different from adults...." Miller v. Alabama, 567 U.S. ___, ___, 132 S.Ct. 2455, 2464, 183 L.Ed.2d 407, 418 (2012); see also State v. Lyle, 854 N.W.2d 378, 390, 402 & n. 8 (Iowa 2014); State v. Ragland, 836 N.W.2d 107, 119, 121 (Iowa 2013); Laurence Steinberg, Adolescent Development and Juvenile Justice, 5 Ann. Rev. Clinical Psychol. 459, 481 (2009) [hereinafter Steinberg] ("[A]s a class, adolescents are inherently less blameworthy than adults."). I join today's opinion because it recognizes this principle. However, I also write separately because in my view, children are so different that article I, section 17 of the Iowa Constitution categorically prohibits sentencing them to life without parole.

As the United States Supreme Court recognized in Roper v. Simmons, there are significant differences between juveniles and adults that "render suspect any conclusion that a juvenile falls among the worst offenders." Roper v. Simmons, 543 U.S. 551, 570, 125 S.Ct. 1183, 1195, 161 L.Ed.2d 1, 22 (2005). Juveniles are impetuous; they lack maturity; and they possess an underdeveloped sense of responsibility. See id. at 569, 125 S.Ct. at 1195, 161 L.Ed.2d at 22. Their incomplete maturation makes juveniles especially vulnerable to "negative influences and outside pressures." Id. This vulnerability is attributable in part to juveniles' character and personality traits which "are more transitory [and] less fixed" than those of adults. Id. at 570, 125 S.Ct. at 1195, 161 L.Ed.2d at 22. "[Y]outh is more than a chronological fact." Eddings v. Oklahoma, 455 U.S. 104, 115, 102 S.Ct. 869, 877, 71 L.Ed.2d 1, 11 (1982). "It is a time of immaturity, irresponsibility, `impetuousness[,] and recklessness.'" Miller, 567 U.S. at ___, 132 S.Ct. at 2467, 183 L.Ed.2d at 422 (alteration in original) (quoting Johnson v. Texas, 509 U.S. 350, 368, 113 S.Ct. 2658, 2669, 125 L.Ed.2d 290, 306 (1993)).

For these reasons and others, we recognize that children are constitutionally different because it is impossible to know when they are beyond rehabilitation. See Roper, 543 U.S. at 570, 125 S.Ct. at 1195, 161 L.Ed.2d at 22 ("The reality that juveniles... struggle to define their identity means it is less supportable to conclude that even a heinous crime committed by a juvenile is evidence of irretrievably depraved character."); see also Miller, 567 U.S. at ___, 132 S.Ct. at 2465, 183 L.Ed.2d at 419 ("[T]he distinctive attributes of youth diminish the penological justifications for imposing the harshest sentences on juvenile offenders, even when they commit terrible crimes."). "[W]e cannot claim that adolescents `ought to know better' if, in fact, the evidence indicates that they do not know better, or more accurately, cannot know better, because they lack the abilities needed to exercise mature judgment." Steinberg, 5 Ann. Rev. Clinical Psychol. at 471.

Although the Supreme Court initially considered these differences in deciding a case involving the death penalty, it later noted their significance in reviewing sentences of life without parole (LWOP) challenged under the Eighth Amendment. See Graham v. Florida, 560 U.S. 48, 68, 130 S.Ct. 2011, 2026, 176 L.Ed.2d 825, 841 (2010) ("[D]evelopments in psychology and brain science continue to show fundamental differences between juvenile and adult minds. For example, parts of the brain involved in behavior control continue to mature through late adolescence."). More recently, the Court considered the importance of the characteristics of youth in reviewing an LWOP sentence imposed on a juvenile offender convicted of homicide. See Miller, 567 U.S. at ___, 132 S.Ct. at 2464, 183 L.Ed.2d at 418-19. In Miller, the court struck down as unconstitutional under the Eighth Amendment a mandatory LWOP sentence that was imposed without consideration of the defendant's "chronological age and its hallmark features — among them, immaturity, impetuosity, and failure to appreciate risks and consequences." Id. at ___, 132 S.Ct. at 2468, 183 L.Ed.2d at 423. The Court also struck down the sentence because it failed to take account of "the family and home environment that surround[ed the defendant] ... no matter how brutal or dysfunctional." Id. "And finally, th[e] mandatory punishment disregards the possibility of rehabilitation even when the circumstances most suggest it." Id.

We have concluded juvenile offenders are also different for purposes of sentencing under article I, section 17 of the Iowa Constitution. See State v. Null, 836 N.W.2d 41, 54-56, 70 (Iowa 2013). The majority recognizes as much, but stops short of concluding an LWOP sentence is categorically unconstitutional for offenses committed by juvenile offenders. I am prepared to go there now because I do not believe we can develop or identify a principled standard for predicting which juvenile offenders are capable of maturation and rehabilitation and which ones are not.

My conclusion that article I, section 17 mandates a categorical ban of LWOP sentences for juvenile offenders is based on several considerations. I first note that an LWOP sentence for a juvenile offender is tantamount to a death penalty in the sense that both sentences are based on a conclusive determination that the offender will never be rehabilitated and able to contribute meaningfully to society. See Graham, 560 U.S. at 69, 130 S.Ct. at 2027, 176 L.Ed.2d at 842 (noting either type of sentence "alters the offender's life by a forfeiture that is irrevocable"); Diatchenko v. Dist. Att'y, 466 Mass. 655, 1 N.E.3d 270, 284 (2013) ("When considered in the context of the offender's age and the wholesale forfeiture of all liberties, the imposition of [LWOP] on a juvenile homicide offender is strikingly similar, in many respects, to the death penalty ...."). Any sentencing scheme that permits such a conclusive determination before the juvenile's potential for maturation and rehabilitation can be reliably known or predicted is in my view intrinsically disproportionate and therefore cruel and unusual.

I acknowledge the Supreme Court has not yet adopted my position that a categorical ban on LWOP sentences for homicide offenses is constitutionally required.1 In Miller, the Court only held unconstitutional mandatory LWOP sentences that are imposed without individualized consideration of an offender's youthful characteristics. Miller, 567 U.S. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 424 ("[T]he Eighth Amendment forbids a sentencing scheme that mandates life in prison without possibility of parole for juvenile offenders.... [W]e do not consider [the] alternative argument that the Eighth Amendment requires a categorical bar on [LWOP] for juveniles...."). The Supreme Court left open the possibility that a juvenile could, consistent with the Eighth Amendment, be sentenced to LWOP, but noted "appropriate occasions for sentencing juveniles to this harshest possible penalty will be uncommon." Id. I would reach a different conclusion under article I, section 17 of the Iowa Constitution because I have no confidence that a principled standard can be developed to distinguish an "uncommon occasion" justifying an irrevocable determination of LWOP from other occasions in which a possibility of parole is required.

Other jurists have shared my lack of confidence in our ability to conceive — or in sentencing courts' ability to apply consistently — a principled standard for identifying the uncommon or rare circumstances justifying LWOP for a juvenile offender. See Graham, 560 U.S. at 77, 130 S.Ct. at 2032, 176 L.Ed.2d at 847 (doubting "that courts taking a case-by-case ... approach could with sufficient accuracy distinguish the few incorrigible juvenile offenders from the many that have the capacity for change"); Roper, 543 U.S. at 573, 125 S.Ct. at 1197, 161 L.Ed.2d at 24 ("It is difficult even for expert psychologists to differentiate between the juvenile offender whose crime reflects unfortunate yet transient immaturity, and the rare juvenile offender whose crime reflects irreparable corruption."); Diatchenko, 1 N.E.3d at 284 (noting that when sentencing juveniles, "the judge cannot ascertain, with any reasonable degree of certainty, whether imposition of th[e] most severe punishment is warranted"). "[E]ven for juveniles who commit murder, their moral culpability compared to adults remains diminished by their age ..., and they, therefore, are still less deserving, as a categorical matter, of the most severe punishments." Mary Berkheiser, Developmental Detour: How the Minimalism of Miller v. Alabama Led the Court's "Kids Are Different" Eighth Amendment Jurisprudence Down a Blind Alley, 46 Akron L. Rev. 489, 501-02 (2013) [hereinafter Berkheiser]; see also Aryn Seiler, Note, Buried Alive: The Constitutional Question of Life Without Parole for Juvenile Offenders Convicted of Homicide, 17 Lewis & Clark L. Rev. 293, 321 (2013) ("[T]he culpability of the juvenile offender is diminished in the homicide case just as it is diminished in the non-homicide case. Culpability belongs to the offender, not the offense.").

Let us suppose that any standard for identifying an "uncommon" case justifying LWOP might call for consideration of the heinous nature of the juvenile offender's crime. This factor is problematic for multiple reasons. First, as the Supreme Court has noted, "[a]n unacceptable likelihood exists that the brutality or cold-blooded nature of any particular crime would overpower mitigating arguments based on youth as a matter of course." Roper, 543 U.S. at 573, 125 S.Ct. at 1197, 161 L.Ed.2d at 24. But even more problematic in my view is the fact that the heinousness of a juvenile's crime is likely to be causally connected with the very attributes and disabilities of youth which cause some folks to cringe at the prospect of LWOP sentences for juvenile offenders. As this court has previously noted, juveniles often fail to appreciate risks and are susceptible to peer pressure; they tend to act impetuously without contemplating the consequences of their behavior. See Null, 836 N.W.2d at 54-56. Thus, the very attributes and disabilities making youth constitutionally different are causal factors increasing the likelihood of heinous behavior. Accordingly, I think it cannot be sensible to suggest that a principled standard for identifying the uncommon case deserving an LWOP should include the heinousness of a juvenile offender's crime.

Other potential factors that might be considered in any standard for identifying the uncommon case suitable for an LWOP sentence are similarly problematic. Consider, for example, the juvenile offender's age. Do we really believe a sentencing court can make a principled distinction between an offender who is fifteen years old and another who is seventeen years old in assessing relative capacities for maturation and rehabilitation? Given what we now know about the incompleteness of brain development during adolescence, I believe the court's ability to predict such capacities of juvenile offenders is largely based on sheer speculation at either age.

Another sentencing consideration commonly included in the analysis of whether an LWOP might be appropriate for a juvenile offender convicted of homicide is whether the offender experienced severe abuse or neglect as a child. But should a juvenile offender's history of horrific abuse or neglect augur in favor of or against LWOP when he or she is sentenced for a homicide? The juvenile offender with such a history of deprivation might be viewed as less culpable than another who was raised in a stable home with caring parents. Yet, the horrifically deprived and abused juvenile offender might have been so deeply scarred by the circumstances of his or her young life that rehabilitation might be a very doubtful and distant prospect.

I suggest the picture is no clearer in the case of the juvenile offender who was raised in a stable home with caring parents. Should the sentencing court conclude this offender found guilty of homicide is more culpable than the child whose family life was characterized by chaos and deprivation? Perhaps; but even if the sentencing court views him as morally more blameworthy, might he nonetheless have better prospects for maturation and rehabilitation because he does not carry the deep scars of deprivation — and might he therefore be a better candidate for parole than our less fortunate hypothetical offender? No matter how the sentencing court might answer these extremely challenging questions, it cannot predict with reasonable certainty which juvenile offender will in fact mature and develop the capacity to become a contributing member of society. Only time will tell.

History shows us that some juvenile offenders convicted of homicide make remarkable progress toward maturity and rehabilitation over time during incarceration. To illustrate this phenomenon, one need only look to State v. Louisell, 865 N.W.2d 590, 2015 WL 3930172 (Iowa 2015), also decided today. Louisell endured a difficult and chaotic childhood before attending college in Iowa beginning in 1987. Id. at 593. She was convicted of first-degree murder after befriending an older, physically handicapped art student, stabbing him in his home, and stealing his wallet. Id. at 593. A jury found she committed a premeditated and deliberate crime. Id. at 584; see Iowa Code § 707.2(1) (1987). Yet, during her time in prison, Louisell earned an associate's degree and a bachelor's degree, learned a trade, became a published author, and became a mentor and tutor for other incarcerated women. Louisell, 865 N.W.2d at 594. In 1988, when Louisell was sentenced to LWOP, few if any participants in the proceedings would have predicted Louisell would shed the disabilities of youth given the nature of her crime. Yet, her accomplishments since then demonstrate that an LWOP determination should not focus on missed opportunities to mature during childhood and adolescence, but on the possibility that a juvenile offender convicted of the most serious of offenses might capitalize on future ones while in prison. Because an irrevocable LWOP determination by a sentencing court is fraught with so much uncertainty attending the juvenile offender's potential for maturation and rehabilitation, I conclude article I, section 17 mandates prohibition of LWOP sentences for all juveniles convicted of homicide offenses.

Some have contended LWOP should remain available as a sentencing option for juvenile offenders convicted of homicides committed after thinking and planning. See People v. Carp, 496 Mich. 440, 852 N.W.2d 801, 843 (2014) ("Because some juvenile offenders ... form an unequivocal premeditated intent to kill in the face of the consequences, it is not categorically disproportionate to punish at least some juvenile offenders the same as adults."). To be sure, the circumstances of Seats's crime suggest he engaged in some deliberation before committing the offense in this case. He knew his friend had a gun, arranged transportation to the victim's residence, and acted at night when the victim would likely be sleeping. These facts are certainly chilling, just like the facts in Roper. See Roper, 543 U.S. at 556-57, 125 S.Ct. at 1187-88, 161 L.Ed.2d at 13 (noting the defendant instigated a plan to commit burglary and murder, acted at night, and threw the victim off a bridge after wrapping her face in duct tape). "But the Constitution does not permit subjective gut reactions to define the sentencing of our young." Berkheiser, 46 Akron L. Rev. at 508.

Furthermore, the circumstances of Seats's crime also highlight the frailty of juvenile reasoning and the undeveloped juvenile capacity to understand the horrible and permanent consequences of behavior. See Steinberg, 5 Ann. Rev. Clinical Psychol. at 467 ("[D]espite the fact that in many ways adolescents may appear to be as intelligent as adults ..., their ability to regulate their behavior in accord with these advanced intellectual abilities is more limited."). Seats worried that he would be reported for committing a crime, so he decided to commit another, more serious crime. He acted so impetuously that he did not even verify he had encountered his intended victim before firing multiple shots. He contacted a police investigator because he "had heard" he was a suspect in the murder and wanted to clear his name, apparently believing his friendly outreach would remove any suspicion the police otherwise had. I recognize there is no assurance that these traits will resolve as Seats ages and matures. Nonetheless, I believe no sentencing court should be able to deprive him of an opportunity, at some point in the future, to demonstrate that they have. See Graham, 560 U.S. at 79, 130 S.Ct. at 2032, 176 L.Ed.2d at 848 ("Maturity can lead to that considered reflection which is the foundation for remorse, renewal, and rehabilitation.").

One other state — Massachusetts — has already determined that juvenile LWOP sentences are categorically prohibited under its state constitution. Diatchenko, 1 N.E.3d at 284-85 ("[W]e conclude that the discretionary imposition of [LWOP] on juveniles who are under the age of eighteen when they commit murder in the first degree violates the [constitutional] prohibition against `cruel or unusual punishment'...."). In doing so, the Supreme Judicial Court of Massachusetts relied on two analytical pillars I would adopt here: first, that the "back end" parole board mechanism better accommodates juveniles' capacity for change than a "front end" irrevocable LWOP determination; and second, that juveniles have diminished culpability no matter the offense they commit. See id. at 282-85. Iowa should join Massachusetts on the path it has forged.2

Juvenile justice evolves in incremental steps. See State v. Pearson, 836 N.W.2d 88, 99 (Iowa 2013) (Cady, C.J., concurring specially). Given the foundation of diminished juvenile culpability and the reasoning set forth in Roper, Graham, Miller, Diatchenko, and our decisions based on article I, section 17 of the Iowa Constitution, the categorical rule I propose in this case is merely the final increment. Because children are constitutionally different, I believe a sentence of life without parole "may not be imposed on [them] ... no matter how heinous the crime." Roper, 543 U.S. at 568, 125 S.Ct. at 1195, 161 L.Ed.2d at 21. Accordingly, I concur in my colleagues' determination that Seats must be resentenced.

MANSFIELD, Justice (dissenting).

This is a difficult case presenting two important issues: First, are life-without-parole sentences for juvenile murderers categorically unconstitutional? Second, even if such sentences are not categorically unconstitutional, do the facts of this case permit such a sentence?

Unfortunately, the court decides neither issue. Instead, it remands the case for an unneeded procedural do-over in which the district court is directed to reapply caselaw it has already applied. This remand not only leaves the present case unresolved, but also provides no helpful guidance to our district courts in other juvenile sentencing cases.

I would not avoid the hard issues this case presents. I would hold, consistent with the decisions of federal appellate courts and all but one state appellate court, that life-without-parole sentences in juvenile homicide cases are not always unconstitutional. I would also hold that under the facts of this case, the district court could constitutionally exercise its discretion to impose a life-without-parole sentence.

Reasonable people can disagree on these matters. But whatever our views may be, I think we ought to come to a decision. We should not leave district courts, defendants, victims, prosecutors, defense attorneys, legislators, and the public in the lurch.

Deciding the appellant's categorical challenge takes on added importance here because the legislature has recently passed a law that retains life without parole as a sentencing option for juveniles who commit first-degree murder. Is that law constitutional? We should say yes or no today, in a case where the issue is squarely presented by the parties.

The court justifies its failure to reach a decision by maintaining that when there are alternative grounds raised on appeal, it only needs to reach one of them. That position has a problem here, however. The relief granted by the majority (a remand for a do-over) is less than the full relief requested by the appellant (vacating the LWOP sentence with no possibility of its being reinstated). Normally, appellate courts do not decline to reach an argument on appeal just because they have reached other arguments that grant lesser relief.

Otherwise stated, it would not be dictum for the court to decide whether Seats can be sentenced to LWOP at all. Rather, it is an abdication of our responsibility not to reach this issue.

I. Additional Relevant Facts.

I will try to avoid repeating facts stated in the majority opinion, but will discuss some additional facts that are relevant to the appellant's as-applied challenge to his sentence.

Damion Seats was just a few months shy of eighteen years old on August 23, 2008, when he went to a party at a friend's trailer in Mason City. Although other people at the party were drinking alcohol and smoking marijuana, Seats was not under the influence of any substances. At the party, Seats and his friend, Andre Wells, handled Wells's handgun and its bullets and discussed robbing "R[e]uben [Ramirez] and the Mexicans." Seats asked Wells for assurance that the clip was not going to jam. Wells responded that it shouldn't.

Before leaving the party, Seats and Wells convinced another friend, Jamie McFarland, to give them a ride to Ramirez's house. When McFarland warned Seats the two of them would get caught, Seats replied, "[D]ead people don't talk."

As explained by the majority, upon entering Ramirez's house, Seats mistook the sleeping victim, Isidoro Cervantes Erreguin, for Ramirez. Seats shot Cervantes five times from a distance of a few feet. Cervantes died as a result of his wounds.

Seats and Wells then returned to the waiting car. Seats stated he had "just shot two Mexicans" and "emptied the whole clip." Seats later returned to the party and indicated that if the cops inquired, the guests should say that Seats and Wells had been at the party all evening.

During his time at the police station on the evening of August 24, where he ultimately confessed to the murder, Seats made the following statements among others:

The agents asked how the victim reacted after Seats shot him and Seats said, "To tell you the truth, I just shot five times and turned my back and walked off."

By the time of trial a year later, Seats was eighteen years and seven months old. McFarland was one of the State's main witnesses, having entered into a plea agreement with the State. McFarland had agreed to plead guilty to aiding and abetting first-degree burglary and to testify at Seats's trial. See Iowa Code §§ 713.1, .3 (2009).3

During the defense case, Seats took the stand. Seats testified he had grown up in Chicago, Illinois, but moved to Charles City with his mother and oldest brother when he was twelve. After a year, he moved with his mother to Mason City. He lived there with his mother and sister for two years, attending the Mason City schools. During Seats's freshman year, his mother moved back to Chicago, but Seats accompanied her for less than a year, returning to Mason City where he attended school through the eleventh grade and played sports. Seats lived with his older brother in Mason City until the brother went to prison. After that, Seats had no regular home; in August 2008 he was "homeless" in his own words, with clothing scattered around several houses, although he often stayed at the house of his best friend, whose mother took care of him.

Seats also testified he had a good relationship with his own mother who was sending him money from Chicago every week. He had just begun to attend the alternative school in Mason City for twelfth grade at the time of the murder. Seats also claimed that he had been planning to start a part-time job the Monday after the shooting.

At trial, Seats recanted his earlier confession. He testified that a man several years older than him named Brandon Crawford had committed the murder. Seats claimed his girlfriend had recently told him she was pregnant. Seats, believing he was going to become a father, testified he was concerned about supporting a child and therefore contacted Crawford to ask if he (Seats) could sell drugs for Crawford to make money. According to Seats, on the night of the shooting, he planned to meet Crawford and pick up drugs. It so happened that the meeting was to occur near Ramirez's house.

Seats thus testified that McFarland was actually driving Seats and Wells so they could meet Crawford, not so they could enter Ramirez's house. Seats testified that when they stopped, Wells got the gun out of the trunk for protection, while Seats urged Wells to "leave the gun" because "[t]here's no reason for it." Thereafter, according to Seats, he entered Crawford's SUV. While inside Crawford's vehicle, Seats allegedly received a bag from Crawford. Seats testified that after he exited Crawford's vehicle and while he was walking back to McFarland's car, Crawford, Wells, and a third person who had been in Crawford's vehicle began to huddle together and have a conversation that Seats could not hear. Wells then supposedly asked for the shirt off Seats's back and proceeded to tie it on his head to cover his face. Seats allegedly continued to walk toward McFarland's car. Seats claimed he did not see where the other three went, but gunshots rang out a short while later. Upon hearing the shots, Seats claimed he ran the rest of the way to McFarland's car. Wells also allegedly reentered McFarland's car soon thereafter. Once they were both in McFarland's car, Wells reportedly handed Seats the gun, wrapped in the t-shirt Seats had previously given him.

Seats denied ever entering Ramirez's house that evening. He admitted hiding the gun under the bushes. In short, Seats told a story consistent with much of McFarland's testimony that nonetheless would have exonerated him of the murder.

Seats went on to testify that the story he had told police during his initial afternoon interview was correct in that he had nothing to do with the shooting. Seats admitted lying during that interview about not being anywhere near the area when the shooting occurred. According to Seats, after he left the first interview, he ran into Crawford. Crawford supposedly slammed Seats to the ground and threatened to harm Seats's family if Seats did not lie to protect Crawford. Seats stated Crawford instructed him to tell the police that only Seats and Wells had been in the house and that one of them shot Ramirez. Seats testified he was scared of Crawford and that was the reason he falsely confessed to the murder during the evening interview. Seats explained he was able to draw a diagram of the murder scene during the second interview because he had previously seen the layout of the house during the night of the fight involving the brick.

The State called Crawford as a rebuttal witness. Crawford testified he was at home from approximately 11:30 p.m. onward on the night of August 23. He denied speaking to Seats on the night of August 23 and claimed he never met with Seats to deliver drugs to him near Ramirez's house. He also denied that he saw or threatened Seats on August 24. Crawford's girlfriend corroborated Crawford's testimony about his being at home on the night of the shooting.

A jury found Seats guilty of both first-degree murder and first-degree burglary. As statutorily required, he was sentenced to life without parole on the first-degree murder conviction.

Four years later, in November 2013, Seats received a resentencing based on the United Supreme Court decision in Miller v. Alabama, 567 U.S. ___, 132 S.Ct. 2455, 183 L.Ed.2d 407 (2012), and our decisions in State v. Ragland, 836 N.W.2d 107 (Iowa 2013), State v. Null, 836 N.W.2d 41 (Iowa 2013), and State v. Pearson, 836 N.W.2d 88 (Iowa 2013).

As pointed out by the majority, the PSI that was prepared for Seats's resentencing covered not only the first eighteen years of Seats's life but also the subsequent four years he had spent in prison. Thus, the PSI noted Seats's difficult childhood, including a lack of adult supervision and an early exposure to gang violence. It also reported Seats had an extensive juvenile criminal history, including assault, going armed with a knife, possession of a controlled substance, and third-degree burglary. And it noted Seats — while imprisoned — had been disciplined ten times. Seats had dropped out of a GED program and was not permitted to hold a job in prison because of his disciplinary status. The majority raises no question about the comprehensiveness of the PSI.

The State presented one witness at the resentencing hearing — a relative of the victim. She testified that Cervantes's fiancée had been pregnant in Mexico with Cervantes's child at the time of the murder and was now raising the child in an impoverished area of Mexico.

Seats, now almost twenty-three years old, also testified at the hearing. His direct testimony, covered in great detail by the majority, described the very serious challenges Seats had to confront while growing up. The State cross-examined Seats only briefly, ending with the following exchange:

As the quotations recited in the majority opinion indicate, the district court clearly understood its role in resentencing Seats. In particular, its job was to follow Miller, Ragland, Null, and Pearson. This meant, as the court put it, that it "must take into account how children are different, and how those differences counsel against irrevocably sentencing them to a lifetime in prison." (Internal quotation marks omitted.) The court said on the record that this was one of the "unusual" cases in which life without parole was warranted, and then explained why. The court specifically acknowledged Seats's troubled youth, but explained that other circumstances carried greater weight. Although the majority has quoted from the district court's explanations and reasoning, the following statement also bears quotation:

I will now address Seats's argument that the Eighth Amendment to the United States Constitution and article I, section 17 of the Iowa Constitution categorically prohibit the sentence of life without parole for persons who commit first-degree murder when under the age of eighteen.4 I will then turn to Seats's alternative, as-applied challenge to his life-without-parole sentence.5

II. Seats's Categorical Challenge to Life-Without-Parole Sentences for Juveniles Convicted of First-Degree Murder.

A. Recent United States Supreme Court Precedent. In Roper v. Simmons, 543 U.S. 551, 575, 125 S.Ct. 1183, 1198, 161 L.Ed.2d 1, 25, (2005), the United States Supreme Court held that the Eighth Amendment categorically prohibits the execution of juveniles who commit murder. "[T]he death penalty is disproportionate punishment for offenders under 18," the Court stated. Id.

The Roper Court initially noted a "national consensus against the death penalty for juveniles" — marked by "the rejection of the juvenile death penalty in the majority of States; the infrequency of its use even where it remains on the books; and the consistency in the trend toward abolition of the practice." Id. at 564, 567, 125 S.Ct. at 1192, 1194, 161 L.Ed.2d at 18, 20. Also, the Court found that due to differences between juveniles and adults, "juvenile offenders cannot with reliability be classified among the worst offenders." Id. at 569, 125 S.Ct. at 1195, 161 L.Ed.2d at 21. "[A] greater possibility exists that a minor's character deficiencies will be reformed." Id. at 570, 125 S.Ct. at 1195-96, 161 L.Ed.2d at 22. Furthermore, the Roper Court observed that juveniles, on the whole, have "diminished culpability," and therefore "the penological justifications for the death penalty apply to them with lesser force than to adults." Id. at 571, 125 S.Ct. at 1196, 161 L.Ed.2d at 23. "Retribution is not proportional if the law's most severe penalty is imposed on one whose culpability or blameworthiness is diminished, to a substantial degree, by reason of youth and immaturity." Id.

Five years later, in Graham v. Florida, 560 U.S. 48, 82, 130 S.Ct. 2011, 2034, 176 L.Ed.2d 825, 850 (2010), the Supreme Court held the Eighth Amendment categorically prohibits a juvenile offender from being sentenced to life without parole for a nonhomicide crime. The Court relied on several considerations.

First, it noted that this sentencing practice is "exceedingly rare." Id. at 67, 130 S.Ct. at 2026, 176 L.Ed.2d at 841. "[O]nly 11 jurisdictions nationwide in fact impose life without parole sentences on juvenile nonhomicide offenders — and most of these do so quite rarely...." Id. at 64, 130 S.Ct. at 2024, 176 L.Ed.2d at 839.

Second, the Graham Court considered culpability and severity. It observed that persons, especially juveniles, "who do not kill, intend to kill, or foresee that life will be taken are categorically less deserving of the most serious forms of punishment than are murderers." Id. at 69, 130 S.Ct. at 2027, 176 L.Ed.2d at 842.

Id. The Court emphasized that LWOP is "the second most severe penalty permitted by law." Id. (internal quotation marks omitted).

After discussing the penological justifications, the Graham Court held the Eighth Amendment requires states to give all juvenile nonhomicide offenders "some meaningful opportunity to obtain release based on demonstrated maturity and rehabilitation." Id. at 75, 130 S.Ct. at 2030, 176 L.Ed.2d at 846.

In Miller v. Alabama, 567 U.S. ___, ___, 132 S.Ct. 2455, 2467, 183 L.Ed.2d 407, 422 (2012), the Supreme Court confronted the constitutionality of LWOP sentences for juvenile offenders convicted of murder. It found that a mandatory life-without-parole sentence was unconstitutional because the Eighth Amendment required individualized sentencing accounting for the offender's youth. Id. As the Court put it,

Id. at ___, 132 S.Ct. at 2467-68, 183 L.Ed.2d at 422. The Miller holding thus had two components. First, a mandatory — as opposed to a discretionary — LWOP sentence for a juvenile murderer is impermissible. Second, in exercising the required discretion, the sentencing authority has to consider the offender's youth and matters relevant to that youth.

Although the Miller Court did not foreclose an LWOP sentence for a juvenile who commits murder, it did state as follows:

Id. at ___, 132 S.Ct. at 2469, 183 L.Ed.2d at 424 (citation omitted) (internal quotation marks omitted).

In short, Miller left open LWOP as a potential sentencing option. Still, it did establish that no juvenile could be sentenced to LWOP unless the sentencing court first conducted a hearing that considered the characteristics of youth and their mitigating effects. And it indicated that appropriate occasions for such sentences would be uncommon. As the Court stated later in the opinion, "[A] judge or jury must have the opportunity to consider mitigating circumstances before imposing the harshest possible penalty for juveniles." Id. at ___, 132 S.Ct. at 2475, 183 L.Ed.2d at 430. The Miller Court condemned mandatory sentencing laws because they "prohibit a sentencing authority from assessing whether the law's harshest term of imprisonment proportionately punishes a juvenile offender." Id. at ___, 132 S.Ct. at 2466, 183 L.Ed.2d at 420-21 (emphasis added).

B. Our Recent Precedent. In the wake of Miller, we have decided several cases on juvenile sentencing. See generally Elisabeth A. Archer, Note, Establishing Principled Interpretation Standards in Iowa's Cruel and Unusual Punishment Jurisprudence, 100 Iowa L. Rev. 323, 337-44 (2014) (discussing the Iowa Supreme Court's recent caselaw under article I, section 17 of the Iowa Constitution). Two years ago, in Ragland, 836 N.W.2d at 122, we held the Governor's blanket commutation of LWOP sentences to life without parole for sixty years resulted in sentencing that did not comply with Miller. We said, "[T]he unconstitutional imposition of a mandatory life-without-parole sentence is not fixed by substituting it with a sentence with parole that is the practical equivalent of a life sentence without parole." Id. at 121. We also summarized five factors that a court must consider at the individualized hearing required by Miller:

Id. at 115 n. 6 (alterations in original) (quoting Miller, 567 U.S. at ___, 132 S.Ct. at 2468, 183 L.Ed.2d at 423).

At the same time, in State v. Null, 836 N.W.2d at 76, we held under the Iowa Constitution that the Miller ruling applies to a mandatory sentence of 52.5 years before parole eligibility. We stated that before imposing this kind of sentence, the trial court must (1) "recognize that because children are constitutionally different from adults, they ordinarily cannot be held to the same standard of culpability as adults in criminal sentencing"; (2) make findings to justify an exception to this general rule; (3) "recognize that [j]uveniles are more capable of change than are adults" and "most juveniles who engage in criminal activity are not destined to become lifelong criminals"; and (4) "recognize that a lengthy prison sentence without the possibility of parole ... is appropriate, if at all, only in rare or uncommon cases." Id. at 74-75 (alteration in original) (internal quotation marks omitted).

Also on the same day, in State v. Pearson, 836 N.W.2d at 96-97, we held under the Iowa Constitution that Miller applies to a sentence of thirty-five years before parole eligibility, comprised of two consecutive mandatory periods of incarceration. We condemned as insufficient a sentencing hearing that "emphasized the nature of the crimes to the exclusion of the mitigating features of youth, which are required to be considered under Miller and Null." Id. at 97. We therefore vacated Pearson's sentence and remanded for "application of the Miller standards as described in Null and this opinion." Id.

Finally, last year, in State v. Lyle, 854 N.W.2d 378, 400 (Iowa 2014), we found all mandatory minimum prison sentences for juveniles unconstitutional under article I, section 17. We concluded that "the sentencing of juveniles according to statutorily required mandatory minimums does not adequately serve the legitimate penological objectives in light of the child's categorically diminished culpability." Id. at 398. We said that "juveniles can still be sentenced to long terms of imprisonment, but not mandatorily." Id. at 401. However, we reserved and did not decide the question whether an LWOP sentence could be imposed on any juvenile who commits murder. Id. n. 7. That question was not before us in Lyle, but is before us today, although the majority declines to decide it.

C. Recent Legislative Action in Iowa and Elsewhere. Following Graham, our general assembly eliminated life without parole as a possible sentence for class "A" felonies committed by juveniles other than first-degree murder. See 2011 Iowa Acts ch. 131, § 147 (codified at Iowa Code § 902.1(2) (2013)). Additionally, during the 2015 legislative session, the general assembly enacted a law that provides three alternatives for juveniles convicted of first-degree murder:

2015 Iowa Legis. Serv. no. 76 (S.F. 448) (West 2015) (to be codified at Iowa Code § 902.1).

This law by its terms applies to "a person who was convicted of a class `A' felony prior to, on, or after the effective date of this Act and who was under the age of eighteen at the time the offense was committed." Id. § 5. It passed the senate by a vote of forty-seven to three, passed the house by a vote of eighty to eighteen, and was signed by the Governor on April 24, 2015. S. Journal, 86th G.A., 1st Reg. Sess., at 626, 932 (Iowa 2015); H. Journal 86th G.A., 1st Reg. Sess., at 803-04 (Iowa 2015). Thus, the Iowa legislature has decided to provide sentencing discretion to the district courts in juvenile homicide cases, as required by Miller, while retaining life without parole as a sentencing option.

In contrast to Iowa, six state legislatures and the District of Columbia have responded to Miller by eliminating LWOP for juveniles convicted of first-degree murder.6 These states join six jurisdictions that already prohibited life without parole for juveniles prior to the Miller decision.7

However, a total of twenty-four jurisdictions in addition to Iowa have retained life without parole as a sentencing option for juveniles who commit murder following Miller.8

Lastly, eleven states that had statutory schemes imposing mandatory life without parole on certain juvenile homicide offenders have yet to pass new legislation conforming their respective statutory schemes to Miller.9

D. Does the Eighth Amendment Categorically Prohibit Life Without Parole for Juveniles Who Commit Murder? To my knowledge, no appellate court has determined that the Eighth Amendment, in light of Miller, categorically prohibits LWOP sentences for juvenile homicide offenders. To the contrary, numerous appellate courts have affirmed LWOP sentences for juvenile murderers post-Miller.10 Miller itself said,

567 U.S. at ___, 132 S.Ct. at 2471, 183 L.Ed.2d at 426.

I would read Miller as every other appellate court has. Miller allows states to impose LWOP sentences on some juveniles who commit murder without violating the Eighth Amendment. Seats would invert the foregoing quotation from Miller (i.e., "does not categorically bar"). He asks us to hold that Miller does categorically bar a penalty for a class of offenders or type of crime. That is not what Miller says.

E. Does Article I, Section 17 of the Iowa Constitution Categorically Prohibit Life-Without-Parole Sentences for Juveniles Who Commit Murder? In considering Seats's categorical challenge under the Iowa Constitution, I believe it is valuable to draw on two additional sources of authority — pre-2013 Iowa caselaw and decisions from other states addressing categorical challenges to juvenile homicide LWOP sentences under their state constitutions. After examining these authorities, I turn to the question whether the Iowa Constitution prohibits all LWOP sentences for juvenile murderers.

1. Additional Iowa caselaw. This court has been dealing with the difficult questions raised by both juvenile sentencing and LWOP sentences for some time. That effort did not begin with the Ragland/Null/Pearson trilogy in 2013.

Thus, our court has held that a mandatory LWOP sentence for an adult who commits first-degree kidnapping does not violate article I, section 17. See State v. Nims, 357 N.W.2d 608, 610-11 (Iowa 1984). We have also upheld against state constitutional challenge a mandatory sentence of 42.5 years' imprisonment before parole eligibility for an adult who commits second-degree murder. See State v. Cronkhite, 613 N.W.2d 664, 669-70 (Iowa 2000).

More recently, we held an LWOP sentence for an adult who committed third-degree sexual abuse for the second time did not violate article I, section 17. See State v. Oliver, 812 N.W.2d 636, 649-53 (Iowa 2012). As a twenty-four-year-old, the defendant had sexual relations with a girl who was fourteen or fifteen, and later as a thirty-three-year-old, he had sexual relations with a girl who was thirteen. Id. at 651. We concluded that no inference of gross disproportionality arose and ended the analysis there. Id. at 653.

We have also said, "We seek to interpret our constitution consistent with the object sought to be obtained at the time of adoption as disclosed by the circumstances." Chiodo v. Section 43.24 Panel, 846 N.W.2d 845, 851 (Iowa 2014); see also Homan v. Branstad, 812 N.W.2d 623, 629 (Iowa 2012) (indicating that in construing a provision of the Iowa Constitution, "our mission `is to ascertain the intent of the framers.'" (quoting Rants v. Vilsack, 684 N.W.2d 193, 199 (Iowa 2004))). Yet when our present constitution was adopted, our laws mandated capital punishment for first-degree murder. See Iowa Code § 2569 (1851). During that time period, juveniles over fourteen were presumed to have the capacity to commit criminal acts, and when tried, were tried as adults. See Lyle, 854 N.W.2d at 390.

In an early case, decided when our constitution was of relatively recent vintage, we upheld the conviction and death sentence of juvenile James Dooley for the murder of his aunt and cousin. See State v. Dooley, 89 Iowa 584, 594, 57 N.W. 414, 417 (1894). Dooley was sixteen when he committed his crimes, and at the time, our laws authorized the jury to determine either death or imprisonment for life at hard labor as the punishment for first-degree murder. Id. at 586-87, 57 N.W. at 415. The jury chose death. Id. at 594, 57 N.W. at 417. We described the facts of the case and also made a number of observations concerning the defendant:

Id. at 591-94, 57 N.W. at 416-17. Dooley was seventeen years old when we affirmed his conviction and sentence and was executed on the grounds of the Iowa State Penitentiary later the same year after he had turned eighteen. See N.N. Jones, Biennial Report of the Warden of the Penitentiary at Fort Madison to the Governor of Iowa 40-41 (1895).

Of course, originalism is not the only available tool in constitutional interpretation. See, e.g., Lyle, 854 N.W.2d at 384 (referring to "evolving standards of decency" (internal quotation marks omitted)); Chiodo, 846 N.W.2d at 854 (same). In this area of law in particular, this court has said that "punishments once thought just and constitutional may later come to be seen as fundamentally repugnant to the core values contained in our State and Federal Constitutions as we grow in our understanding over time." Lyle, 854 N.W.2d at 385. My point here is simply that originalism would not support a categorical ban on the death penalty for juveniles who commit murder, let alone a ban on life without parole.

Additionally, we have long recognized that discretion in sentencing can alleviate possible constitutional problems under article I, section 17. In State v. Teeters, 97 Iowa 458, 462-63, 66 N.W. 754, 756 (1896), we rejected a constitutional challenge to a law permitting a sentence of up to five years in prison or up to a $500 fine for obstructing a public highway, emphasizing that this was simply a maximum. As we put it, "If the law fixed arbitrarily the excessive punishment, the claim of the law being unconstitutional because of it would be more tenable." Id. at 463, 66 N.W. at 756.

2. State constitutional rulings in other jurisdictions. In the aftermath of Miller, a number of state appellate courts have addressed under their respective state constitutions categorical challenges to life-without-parole sentences for juvenile murderers. In all but one instance, they have overruled those challenges. See, e.g., People v. Palafox, 231 Cal.App.4th 68, 179 Cal.Rptr.3d 789, 805 (2014) (disagreeing with the proposition that "an LWOP term cannot properly be imposed under California law or the Eighth Amendment" (emphasis added)); Bun v. State, 296 Ga. 549, 769 S.E.2d 381, 383-84 (2015) (rejecting the defendant's argument that imposition of an LWOP sentence violated the Georgia Constitution); State v. Fletcher, 149 So.3d 934, 944, 950 (La.Ct.App.2014) (rejecting a claim that the district court's imposition of a life-without-parole sentence following a post-Miller resentencing violated the Louisiana Constitution); State v. Ali, 855 N.W.2d 235, 258-59 (Minn.2014) (rejecting the argument that the discretionary imposition of consecutive life sentences that are the practical equivalent of life without parole violated the Minnesota Constitution); State v. Houston, ___ P.3d ___, ___, 2015 WL 773718, at *14-15 (Utah Mar. 13, 2015) (rejecting the argument that LWOP is a categorically impermissible sentence under the Utah Constitution for a juvenile convicted of murder and noting that "a majority of our sister states as well as the federal system permit LWOP for juveniles convicted of the most heinous crimes").

In one case, the Michigan Supreme Court took note that Michigan's constitution, unlike the United States Constitution and the Iowa Constitution, contains disjunctive wording and prohibits punishments that are either "cruel or unusual." People v. Carp, 496 Mich. 440, 852 N.W.2d 801, 844 (2014) (emphasis in original) (internal quotation marks omitted), petitions for cert. filed sub nom. Carp v. Michigan (U.S. Jan. 13, 2015) (No. 14-824), Davis v. Michigan (U.S. Jan. 23, 2015) (No. 14-8106). The court went on,

Id. (emphasis in original) (internal quotation marks omitted). Yet despite this textual difference, the court was unwilling to conclude that LWOP was so disproportionate a punishment for a juvenile homicide offender as to be unconstitutional in all cases. Id. at 845-46.

In another case, the Pennsylvania Supreme Court similarly denied a categorical challenge to an LWOP sentence for a juvenile homicide offender, even though Pennsylvania's constitutional language differs from the Eighth Amendment. See Commonwealth v. Batts, 620 Pa. 115, 66 A.3d 286, 299 (2013). The Pennsylvania Constitution prohibits "cruel punishment" — whether unusual or not. Id. at 298 (internal quotation marks omitted). Nonetheless, the Batts court concluded,

Id. at 298-99.

Lastly, the Indiana Supreme Court also upheld a post-Miller LWOP sentence for a juvenile over a state constitutional challenge. Conley v. State, 972 N.E.2d 864, 879-80 (Ind.2012). Under Indiana law, an LWOP sentence may be imposed only after the sentencing court identifies all aggravating and mitigating circumstances, includes the facts and reasons that support those findings, balances those circumstances, and determines the sentence is appropriate. Id. at 873. The court must also find at least one aggravating circumstance and that the aggravating circumstances outweigh the mitigating circumstances. Id.

The Indiana Supreme Court acknowledged that the Indiana Constitution "can provide more protections than the United States Constitution provides" and its "language is not the same." Id. at 879. In particular, the Indiana Constitution states, "`The penal code shall be founded on the principles of reformation, and not of vindictive justice.'" Id. (quoting Ind. Const. art. 1, § 18). Still, the court found no constitutional violation, noting that the defendant was "only the fourth juvenile sentenced to a life-without-parole sentence" in Indiana. Id. at 880. The court observed that in Indiana, "[l]ife without parole is reserved for use in only the most heinous of crimes that so shock our conscience as a community." Id.

One state constitutional decision is to the contrary. In Diatchenko v. District Attorney, 466 Mass. 655, 1 N.E.3d 270, 276, 282-85 (2013), the Massachusetts Supreme Judicial Court acknowledged that Miller foreclosed only mandatory life-without-parole sentences for juvenile homicide offenders under the Eighth Amendment, yet invalidated all life-without-parole sentences for juveniles in Massachusetts under Article 26 of the declaration of rights in that state's constitution. The relevant provision of that article bars courts from inflicting "cruel or unusual punishments." Mass. Const., pt. 1, art. 26.11

The Massachusetts court based its reasoning on two points — first, the inability of courts to determine with a high degree of confidence whether a juvenile offender can or cannot be rehabilitated, and second, the similarity between life without parole and the death penalty (the latter of which the Massachusetts Supreme Judicial Court had previously found to be unconstitutional in all circumstances). See Diatchenko, 1 N.E.3d at 283-84. Thus, the court explained,

Id. (footnote omitted) (citations omitted). The court then added,

Id. at 284. It further observed,

Id. at 284 (citations omitted).

The views of the Diatchenko court need to be considered carefully because they distill the case for a categorical ban on life-without-parole sentences for juvenile homicide offenders. The first argument asserts that with juveniles, a sentencer cannot confidently say whether or not a juvenile can be rehabilitated, so the only constitutional outcome is always to allow the possibility of parole. Id. at 283-84. The second argument holds that life without parole is simply too harsh and disproportionate a sentence to impose on any juvenile. Id. at 284. I will examine these arguments in turn.

3. Does Iowa's constitution categorically prohibit life without parole for juvenile murderers? As noted, the Massachusetts Supreme Judicial Court gave two reasons in Diatchenko for imposing a categorical ban under the Massachusetts Constitution on life-without-parole sentences for juveniles who commit murder — the inability of courts to determine with confidence whether a juvenile can be rehabilitated, and the overall harshness of the life-without-parole sentence for juveniles. Id. at 283-84.

One possible answer to the first argument is that the judicial process is always subject to error. Predicting when or whether a person can be rehabilitated is far from a science. Divining when or whether a juvenile can be rehabilitated is even more difficult, as we have previously noted. Yet we have made clear that sentencing courts may impose lengthy periods of required incarceration on juveniles if they do so after considering the mitigating attributes of youth. In Lyle, we expressed confidence in our trial judges:

854 N.W.2d at 403-04.

Also, Miller and its progeny rely heavily on parole boards as the backstop to the process; yet a parole board's determination that someone has or has not been rehabilitated is likewise subject to error.

Furthermore, focusing exclusively on the difficulty of determining at the time of sentencing whether a juvenile can be rehabilitated overstates the scope of Miller and our cases. Rehabilitation is not the only legitimate goal served by imprisonment, even for juveniles. Rather, our criminal justice system takes into account retribution, deterrence, and incapacitation as well. See Oliver, 812 N.W.2d at 646. If rehabilitation were the sole proper goal, it would follow that all sentences for juveniles should come with immediate parole eligibility. Miller does not go that far and does not hold that rehabilitation is the only consideration that may govern sentencing of juvenile homicide offenders. It simply holds that because of the capacity of juveniles to reform, and their diminished culpability, the factors of youth must be considered in a discretionary sentencing process.

Nor does Lyle go that far. As we put it in Lyle,

854 N.W.2d at 401 (footnote omitted) (citations omitted). We observed in Lyle that "justice requires us to consider the culpability of the offender in addition to [not exclusive of] the harm the offender caused." Id. at 398 (emphasis added). Thus, both Miller and our cases allow the sentencing court to consider the nature of the crime, so long as the court also considers all relevant attributes of youth.12

I therefore turn to the Massachusetts Supreme Judicial Court's second point. This, I believe, is the heart of Seats's categorical argument — namely, that an LWOP sentence violates article I, section 17 because it is simply too harsh and disproportionate ever to be imposed on a person who commits first-degree murder while under the age of eighteen.

To be sure, in recent years, both the United States Supreme Court and this court have recognized "a fundamental and virtually inexorable difference between juveniles and adults for the purposes of punishment." Id. at 393. This difference is presently reflected in Iowa law, which mandates LWOP for adults who commit first-degree murder but provides no mandatory minimum period of incarceration at all for a juvenile who commits the same crime. Compare Iowa Code § 902.1(1) (2009), with 2015 Iowa Legis. Serv. no. 76 (S.F. 448) (West 2015).

The question is whether this difference between adults and juveniles is so vast that an LWOP sentence for a juvenile who commits murder has become "off the charts" in all situations. See State v. Bruegger, 773 N.W.2d 862, 867, 886 (Iowa 2009) (internal quotation marks omitted) (holding that a mandatory sentence of 21.25 years for an adult who committed statutory rape and had been previously adjudicated a delinquent for two counts of criminal sexual conduct in the first degree was "off the charts" such that a hearing was required to determine the constitutionality of the sentence (internal quotation marks omitted)). I believe it is not.

To begin with, we do not have a situation as in Roper where there is a "national consensus" against the punishment. 543 U.S. at 564, 125 S.Ct. at 1192, 161 L.Ed.2d at 18; see also Oliver, 812 N.W.2d at 641-46 (emphasizing the importance of a national consensus). The sentence is not "exceedingly rare" as in Graham, 560 U.S. at 67, 130 S.Ct. at 2026, 176 L.Ed.2d at 841. To the contrary, even in the wake of Miller, LWOP remains a statutorily available sentence for juvenile homicide offenders in thirty-six jurisdictions, including Iowa. Legislatively speaking, "Iowa is not an outlier." Oliver, 812 N.W.2d at 641.

Also, turning to judicial decisions in other states-another consideration we deemed relevant in Oliver, see id. at 643-it is noteworthy that almost all post-Miller state appellate courts to rule (Massachusetts being the only exception) have upheld as constitutional discretionary life-without-parole sentences for juvenile homicide offenders.

Nor do we have a Roper/Graham scenario where the sentence may exist more in theory than in practice. Miller was decided less than three years ago, yet there at least fifteen cases in which juvenile homicide offenders have already been sentenced or resentenced, post-Miller, to life without parole and the sentences have been upheld on appeal.13

A statewide consensus against this punishment cannot be discerned either. As I've mentioned above, during the recently adjourned legislative session the general assembly by large bipartisan majorities approved a Miller fix that leaves life without parole as a sentencing option for juveniles who commit first-degree murder.

Of course, this court must also make an independent judgment whether a sentence violates the constitution. Lyle, 854 N.W.2d at 398; Oliver, 812 N.W.2d at 646. A fundamental consideration here is whether the sentence serves legitimate penological goals. Lyle, 854 N.W.2d at 398; Oliver, 812 N.W.2d at 646. Clearly, an LWOP sentence serves no rehabilitative goal. Oliver, 812 N.W.2d at 646. And while retribution is certainly a permissible goal of punishment, there must be a relationship between the punishment and the defendant's culpability. Id.

Juveniles do not have "adult-like culpability." Lyle, 854 N.W.2d at 398. Still, the intentional, premeditated taking of another person's life is the most serious offense a person can commit, and society is entitled to recognize this point, even when the person committing the crime was under the age of eighteen. I cannot say that life without parole falls so far short of serving legitimate penological goals in all cases involving juvenile homicide offenders as to be "cruel and unusual" within the meaning of article I, section 17.

"[W]e owe substantial deference to the penalties the legislature has established for various crimes." Oliver, 812 N.W.2d at 650. The issue for me is not whether I agree with this particular sentence, any more than that was the issue when my predecessors decided Dooley over a century ago. See 89 Iowa at 594, 57 N.W. at 417. The issue is whether the Iowa Constitution imposes a total ban on life-without-parole sentences for juvenile murderers. I am unable to say that LWOP is such a disproportionate penalty in all instances for a person who commits a murder before reaching the age of eighteen that it violates the Iowa Constitution.

F. The Court's Failure to Reach Seats's Categorical Challenge. Unfortunately, the court does not reach the question whether article I, section 17 prohibits LWOP sentences for juvenile murderers in all cases. That means the issue will have to continue to be litigated in Iowa. I do not understand or agree with the court's refusal to reach this issue.

For one thing, there is precedent for our upholding a law against a facial challenge while at the same time finding the law unconstitutional as applied. Glowacki v. State Bd. of Med. Exam'rs, 501 N.W.2d 539, 541-42 (Iowa 1993); cf. State v. Hernandez-Lopez, 639 N.W.2d 226, 235, 242 (Iowa 2002) (upholding material witness law against facial challenge because it raised "issues of public importance" even while dismissing the as-applied challenge as moot).

Even more importantly, the categorical challenge and the as-applied challenge do not afford Seats the same relief. If Seats prevailed on his categorical challenge, he could not be sentenced to LWOP. However, the court's ruling leaves Seats subject to an LWOP sentence on remand. Thus, it grants Seats less relief than a successful categorical challenge to the Iowa statute would provide. It is not fair or logical for an appellate court to say it is unnecessary to reach an appellant's first ground for appeal just because the court is reaching another ground that provides more limited relief. This is like remanding a case for new trial based on an instructional error while ignoring the appellant's initial argument that he or she should have received a directed verdict.

Texas has a well-developed and well-reasoned body of law on this issue. "Generally, when a party presents multiple grounds for reversal of a judgment on appeal, the appellate court should first address those points that would afford the party the greatest relief." Bradleys' Elec., Inc. v. Cigna Lloyds Ins. Co., 995 S.W.2d 675, 677 (Tex.1999); cf. Boykins v. Shinseki, No. 13-0942, 2014 WL 840096, at *5 (Vet.App. Mar. 5, 2014) ("Given that the Court is remanding the appellant's claim, and because none of the appellant's other allegations of error could result in greater relief, the Court need not address the appellant's remaining arguments."); Tischhauser v. Little, 179 Kan. 551, 296 P.2d 1118, 1119 (1956) (reversing and remanding for a new trial because of an evidentiary error, finding that it was not error to overrule the appellant's directed verdict motion, and declining to reach the appellant's other appellate arguments because they were also arguments for a new trial and "could afford appellant no greater relief than that already granted"). There is no juridical or practical reason to avoid reaching the question whether the Iowa Constitution categorically forbids the imposition of an LWOP sentence on a juvenile who commits murder.

III. Seats's As-Applied Challenge to His Life-Without-Parole Sentence.

Seats's other ground for appeal is his as-applied challenge to his sentence. He maintains that even if LWOP (or its functional equivalent) for juveniles who commit murder does not categorically violate the Iowa Constitution, his particular LWOP sentence did not comply with the requirements of Miller, Ragland, and Null.14

A. The Majority's Criticisms of the District Court. Although the district court clearly tried to follow Miller and our caselaw, my colleagues fault the court for not doing the job well enough. They therefore send the case back for more work — or, I would argue, the same work. The majority identifies four Miller/Ragland/Null "factors" the court allegedly did not consider: (1) "the presumption" in favor of a sentence less than life without parole; (2) the juvenile offender's "`family and home environment'"; (3) the "`circumstances of the homicide offense'"; and (4) the "consideration that `[j]uveniles are more capable of change than adults.'" (Alteration in original.) (Internal quotation marks omitted.).

Additionally, the court offers three further criticisms of the district court:

(5) The court should not have "emphasized that Seats was a seventeen-year-old at the time the crime was committed."

(6) The court needed to "make specific findings of fact discussing why the record rebuts the presumption" against life without parole.

(7) The court "appeared to use Seats's family and home environment vulnerabilities together with his lack of maturity, under developed sense of responsibility, and vulnerability to peer pressure as aggravating, not mitigating factors."

I do not agree with any of these seven criticisms. In fact, I think these criticisms are quite unfair. Let's compare what the majority claims the district court didn't do and what the district court actually did:

1. Alleged failure to apply the presumption against LWOP. The district court did not overlook this factor. To the contrary, the court acknowledged that it must "take into account how children are different, and how those differences counsel against irrevocably sentencing them to a lifetime in prison." (Internal quotation marks omitted.). The district court also accepted that "only in the unusual case should a juvenile life sentence without the possibility for parole be imposed." It then expressly determined that "this case is one of those unusual cases," following this determination with several paragraphs of findings.

2. Alleged failure to consider the juvenile offender's family and home environment. The district court did not disregard Seats's family and home environment. It said,

3. Alleged failure to consider the circumstances of the offense. Again, this criticism is misplaced. Here is what the district court stated:

4. Alleged failure to consider that juveniles are more capable of change than adults. The district court did not miss this factor, either. As noted above, it acknowledged Miller's teaching regarding "the `attendant characteristics' of youth." Yet it also observed that Seats had not changed in over four years as an adult, had incurred ten major disciplinary reports in prison, and continued to deny his guilt and showed no remorse for the crime committed.

5. Alleged emphasis on Seats being nearly eighteen years old when the crime was committed. It is true that a single sentence of the district court's order said, "When he killed [Cervantes], Mr. Seats was only months away from being an adult." I would not consider one sentence to be emphasis. Furthermore, Miller and Ragland instruct sentencing courts that they should consider the juvenile's "chronological age." Miller, 567 U.S. at ___, 132 S.Ct. at 2468, 183 L.Ed.2d at 423; Ragland, 836 N.W.2d at 115 n. 6 (internal quotation marks omitted). Miller even characterized its holding as "requir[ing] factfinders ... to take into account the differences among defendants and crimes," including the distinction between seventeen year olds and fourteen year olds. Miller, 567 U.S. at ___ n. 8, 132 S.Ct. at 2469 n. 8, 183 L.Ed.2d at 424 n. 8. So it was entirely appropriate for the district court to make reference to Seats's age at the time of the murder.

6. Alleged failure to make specific findings to overcome the presumption against LWOP. I do not understand this criticism. The district court made a specific finding that this was "one of those unusual cases [where LWOP could be imposed]," and then gave several paragraphs' worth of findings and reasons.

7. Alleged use of Seats's family and home environment vulnerabilities together with his lack of maturity, underdeveloped sense of responsibility, and vulnerability to peer pressure against him. I do not follow this criticism either. The district court expressly found that this murder did not arise out of peer pressure; rather, Seats was "a primary actor." The district court also acknowledged Seats's "unfortunate background," "the difficulties he faced in his youth," and "the bleakness and desperation of [Seats's] life" as mitigating factors, but found them outweighed by other considerations it identified.

Miller does not require that we take the general characteristics of hardened criminals — such as their inability to acknowledge wrongdoing, their lack of remorse, their continuing illegal activity, and their failure to respond to interventions and attempts at rehabilitation — and treat them as items to be placed on the defendant's side of the ledger.

For all these reasons, in contrast to the majority, I do not believe a remand is necessary for more fact-finding.

B. Seats's Argument that His Case Was Not Heinous Enough. Seats's as-applied challenge also has a substantive dimension not addressed by the majority. Thus, apart from the question whether the district court followed the proper procedure in resentencing him, Seats maintains that "his case does not rise to the heinous level" where Miller permits an LWOP sentence.

To date, other jurisdictions have been divided on whether Miller's sentencing requirements are basically procedural or whether there is also a substantive component. Under the former approach, the appellate court's duty is to determine whether the sentencing court took the youth-related factors into account, not to analyze whether the court's findings and ultimate conclusion are actually supported by the evidence. See, e.g., United States v. Guerrero, 560 Fed.Appx. 110, 112 (2d Cir. 2014) (affirming the defendant's resentencing to life without parole because "[t]he district court properly considered all of the Miller factors"); Copeland v. State, 129 So.3d 508, 511 (Fla.Dist.Ct.App.2014) ("[T]he sentencing court conducted an individualized mitigation inquiry, considering several potential mitigating factors before finding that life without the possibility of parole was, nevertheless, appropriate in this case. Accordingly, we AFFIRM Copeland's judgment and sentence."); Commonwealth v. Seagraves, 103 A.3d 839, 850 (Pa.Super.Ct.2014) ("Because our review of the record readily reveals that the trial court considered these factors before re-imposing the sentence, we affirm Appellant's life sentence without the possibility of parole.").

But another group of appellate courts have undertaken to review the record to determine not only whether the sentencing court considered the correct factors, but also whether its findings are supported by the evidence such that the case is truly an "uncommon" one. Hence, in Palafox, the California Court of Appeal performed its own "independent review." 231 Cal.App.4th 68, 179 Cal.Rptr.3d at 806. The court elaborated,

Id. (footnote omitted) (citations omitted). In a footnote, the court referred to the defendant's "chaotic and unfortunate upbringing and environment," but noted the same report "did not address any potential for rehabilitation." Id. n. 17, 179 Cal.Rptr.3d 789.

Likewise, the North Carolina Court of Appeals examined for itself whether the trial court's findings of fact were supported by substantial evidence and whether they supported the trial court's ultimate conclusion. See State v. Lovette, ___ N.C.App. ___, 758 S.E.2d 399, 407-10 (2014). Upon its review, the court found the facts did support an LWOP sentence: "[T]his case is uncommon." Id. at 410. In its opinion, the appellate court recited some of the pertinent facts, including the "defendant's active planning and participation in a particularly senseless murder," the fact that the defendant was seventeen years old and "of a typical maturity level for his age," the fact that the defendant had a stable upbringing, and his extensive juvenile record despite the rehabilitative programs offered by the juvenile court. Id.

Similarly, in Fletcher, the Louisiana court conducted its own "complete and thorough review of the entire record of all of the proceedings, including all of the testimony and evidence adduced at the trial and the Miller hearing, and all of the exhibits introduced in these proceedings." 149 So.3d at 944. Convinced that the trial court had considered "the relevant factors," and fortified by its own "careful review of the entire record," the court upheld the trial court's resentencing of the defendant to life without parole. Id. at 950; see also State v. Brooks, 139 So.3d 571, 576 (La.Ct.App.2014) (sharing the trial court's conclusion "that the facts of this case should preclude parole eligibility for this remorseless killer").

I agree with the approach taken by the latter group of courts. Miller — especially as amplified by our holdings under the Iowa Constitution — requires us to perform a substantive as well as a procedural review of any juvenile LWOP sentence. Thus, when reviewing any such sentence, I would consider whether the district court's findings on the Miller/Ragland/Null factors are supported by substantial evidence, and also independently decide whether the record supports a determination that the case is sufficiently uncommon — based on those same factors — that an LWOP sentence can be constitutionally imposed.

This leads to the question of what the standard of review should be. The State urges abuse of discretion — our traditional deferential standard for reviewing criminal sentences. I disagree. Abuse of discretion might be the right standard if the only question were whether the district court considered the appropriate factors — the typical inquiry in sentencing appeals. See State v. Valin, 724 N.W.2d 440, 444 (Iowa 2006) (stating that the standard of review for sentencing appeals is abuse of discretion when a sentence falls within statutory limits). However, if the review is to go beyond procedure, a less deferential standard of review is required.

Accordingly, I think this court should examine whether the district court's findings on any Miller/Ragland/Null factors are supported by substantial evidence, and perform a de novo review to determine whether a case is sufficiently uncommon, based upon consideration of those factors, that a sentencer could constitutionally impose a life-without-parole sentence. The issue, again, would not be whether the appellate court would have imposed the same sentence, but whether there are sufficient indicia the case is out of the mainstream of juvenile homicide cases that an LWOP sentence is a constitutional option.15

I believe the district court's findings of fact at the resentencing are supported by substantial evidence; indeed, Seats does not challenge any of them on appeal. I would also conclude from an independent review that this is the kind of rare case where a district court, exercising its discretion and after considering all the circumstances of youth presented, could constitutionally impose an LWOP sentence.

First, the defendant's chronological age was just a few months short of eighteen. He did not act impetuously. A murder — really an execution — was planned; Seats's purpose was to kill someone he was worried would go to the police and report him.

Second, as to the circumstances of the murder, Seats was the gunman, and he "emptied the whole clip" into a man who was sleeping a few feet away. Seats was not under the influence of any substances. He was not provoked; he did not act in self-defense or the heat of passion; he planned the killing under his own initiative without any peer pressure.

Third, there is no indication Seats's youth had any bearing on his ability to defend himself in the legal system. In fact, Seats was no longer a juvenile at the time of trial. Nothing in the record suggests that any plea offer was made to Seats before trial, let alone turned down by him because of his youth. At trial, Seats took the stand and testified for most of a day, presenting a detailed, if ultimately unconvincing, defense that was designed to conveniently explain away a good deal of the prosecution's evidence.

Fourth, while most young people change and mature as they get older, the district court accurately summarized this record as not showing any discernible prospects for rehabilitation. All rehabilitation efforts failed when Seats was a juvenile.16 In prison, Seats had only made what the district court accurately termed a "half-hearted effort at obtaining his GED."17 Further, as noted by the district court, Seats failed to show remorse up to the day of his resentencing. Four years after the crime, at the age of twenty-two, Seats continued to deny that he killed Cervantes. Even when he briefly admitted the crime to police, his only regret was that he had shot Cervantes rather than Ramirez.

It is true that one factor weighs quite significantly in Seats's favor — his seriously troubled family and home environment. The district court acknowledged and considered this point, as it had to. I believe this factor alone, though, does not render an LWOP sentence unconstitutional under the circumstances of this case. Other courts have reached similar conclusions.18

The present case stands a considerable distance from the botched robberies committed by fourteen year olds that were involved in Miller, 567 U.S. at ___, 132 S.Ct. at 2465, 183 L.Ed.2d at 420, the impulsive stabbing of a client committed by a teenage model who later became an exemplary inmate, State v. Louisell, 865 N.W.2d 590, 591, 2015 WL 3930172 (Iowa 2015), and the fatal blow with the tire iron that was struck in a fight by someone other than the defendant, Ragland, 836 N.W.2d at 110.

Given the deference we must afford on the one hand to the legislature's determination of sentencing options and on the other hand to the trial court's exercise of sentencing discretion, I would not find this sentence violates either the Eighth Amendment or article I, section 17 of the Iowa Constitution.

IV. Conclusion.

For the foregoing reasons, I respectfully dissent and would affirm the resentencing below.19
