JORDAN, Circuit Judge.

       The government appeals from an order of the United States District Court for the

District of Delaware granting Marquis Lopez a new trial after his conviction for

possession with intent to distribute 100 grams or more of heroin and for two related

firearm offenses. Before trial, the District Court had granted the government’s in limine

motion authorizing the admission into evidence of Lopez’s 2001 state conviction for a

similar offense, namely possession with intent to deliver heroin. In granting the

government’s multi-part motion, however, the Court focused on a different aspect of the

motion – the question of whether certain surveillance evidence was admissible – and it

provided no rationale for admitting the 2001 conviction. Thus, when it considered

Lopez’s request for a new trial, the Court concluded that the absence of any justification

for the admission of the prior conviction warranted a new trial. We agree with the

District Court’s thoughtful analysis and will affirm.

I.     BACKGROUND

       On July 6, 2010, Lopez was charged in a three-count indictment with possession

with intent to distribute 100 grams or more of heroin, possession of a firearm in

furtherance of a drug trafficking crime, and being a felon in possession of a firearm. The

charges stemmed from a traffic stop on Interstate 95, during which police officers found

over 100 grams of heroin and a firearm in a hidden compartment under a rear seat in the

car Lopez was driving. On March 14, 2014, following a five-day trial, a jury convicted

Lopez of all three counts of the indictment. A central issue at trial was Lopez’s

knowledge that the drugs and gun were in the vehicle’s hidden compartment at the time

of arrest.

       In the four years between charge and trial, a number of issues were litigated.

Lopez filed multiple motions to suppress, all generally involving evidence about the

                                             2
vehicle’s whereabouts obtained using Global Positioning System (“GPS”) technology.

The government filed motions in limine dealing chiefly with the same issues. Due to the

changing legal landscape related to GPS technology during that time, see United States v.

Jones, 

(2012), the District Court issued multiple decisions on those

motions.

       In one of its in limine motions related to the GPS data, the government also

sought, under Federal Rule of Evidence 404(b), to admit evidence of Lopez’s 2001

Delaware Superior Court conviction for possession with intent to deliver heroin, as proof

of knowledge and intent. The government argued that admission of the prior drug

conviction would demonstrate Lopez’s “familiarity with the subterfuge and concealment

inherent in drug trafficking,” making it less likely that he would be ignorant of the illicit

contents of the hidden compartment in the car he was driving. (App. at 103.)

       The District Court granted the government’s motion in its entirety, but in its

written opinion it addressed only the issues related to electronic surveillance and GPS

technology. Later, noting the development of further case law on the subject, the Court

ordered additional briefing and issued a second opinion granting the government’s

motion without any discussion of Lopez’s 2001 conviction.1 In short, the Court allowed

the admission of Lopez’s prior conviction but did not provide any rationale for doing so.



       1
        The prior conviction was referenced in the concluding sentence of the District
Court’s first of the two orders granting the government’s motion: “For the foregoing
reasons, the court hereby denies Lopez’s Second Motion to Suppress Evidence (D.I. 90)
and grants the government’s First Motion in Limine to Admit Evidence of Other Acts
Pursuant to Federal Rule of Evidence 404(b) (D.I. 82).” (App. at 130.) In its second
                                              3
       Given the Court’s ruling, the following stipulation was read into evidence at the

conclusion of the government’s case:

       The United States, by and through its attorneys, Charles M. Oberly, III,
       United States Attorney for the District of Delaware; and Shawn A. Weede,
       Assistant United States Attorney; John S. Malik, Esquire, attorney for the
       defendant; Marquis A. Lopez, and the defendant, Marquis A. Lopez, hereby
       stipulate and agree that, prior to the date alleged in Count 3 of the
       indictment (on or about June 3, 2010), the defendant, Marquis A. Lopez,
       was convicted of possession with intent to deliver a narcotic Schedule 1
       controlled substance, to wit, heroin, on July 2nd, 2001, in Superior Court in
       and for New Castle County, Delaware, in ID No. IN0103007453, and
       Criminal Action No. 01-03-1534. This is a felony crime punishable by
       imprisonment for a term exceeding one year.

(App. at 411.)

       At a sidebar conference immediately after the stipulation was read to the jury, the

District Court indicated it was “shocked” at the nature of the stipulation. (App. at 412.)

After a brief recess, the District Court again summoned counsel to sidebar and expressed

its concern that the evidence could be seen as “propensity evidence” and that they have to

“keep the playing field level here.” (App. at 412.) After the government’s attorney

described the Court’s prior ruling, the District Court asked him to “[r]emind me of the

motion and the Court’s ruling on that.” (App. at 412.) The Court stated that it was

“ex[e]rcised about it” and did not remember the ruling. (App. at 412.) The Court further

indicated that it was “not sure that that was the correct ruling.” (App. at 412.) In the

Court’s words: “I just cannot imagine what would be more vivid evidence of propensity,

which is certainly not what you want this jury to base its conviction on.” (App. at 412.)


order, the District Court used a verbatim concluding sentence in “reaffirm[ing]” its prior
decision. (App. at 148.)
                                             4
After further discussion, the Court noted that “there are legitimate reasons for the

conviction to come in as articulated in the previous ruling,” though, as stated, the

previous ruling contained no such reasoning. (App. at 413.)

       After the guilty verdict, Lopez filed a motion for new trial pursuant to Federal

Rule of Criminal Procedure 33(a). He submitted that it was error for the Court to admit

the evidence of his conviction without some indication in the record that the prior crime

and the charged crime were “in any way factually similar.” (App. at 39.) He argued that

he “was unfairly prejudiced and denied his right to a fair trial” because of the admission

of the conviction, “since it was likely that the jury used this evidence to conclude that he

was a bad person with a propensity to commit crimes.” (App. at 39.) In a supporting

memorandum of law, Lopez discussed the District Court’s failure to justify the admission

of the conviction in either of its written opinions.

       The District Court granted the motion. Setting aside the merits of whether the

prior conviction should have been admitted into evidence, the Court acknowledged that it

had “not provide[d] any supportive reasoning on the record for its [earlier] decision.”

(App. at 15.) It concluded that it had erred in assessing only the GPS evidence and

ignoring the additional issues included in the government’s motion in limine. The Court

said that, “[i]n light of the lack of a record to support the court’s Orders granting the

government’s motions it is necessary in the interest of justice that Lopez be granted a

new trial.” (App. at 15.) The Court elaborated on that reasoning in a later order

addressing the government’s motion for reconsideration. Responding to the

government’s contention that it need do nothing more than “adopt[] a provided rationale

                                               5
offered by the government” (App. at 8), the Court concluded that, while that may be true,

it simply had not done so. At no point had it actually indicated that it agreed with and

adopted the government’s rationale. (App. at 10.) After a “painstakingly comprehensive

review” of the case file, the District Court concluded that it should grant Lopez a new

trial. (App. at 7.)

       The government then filed this timely appeal.

II.    DISCUSSION2

       Upon a defendant’s motion, “the court may vacate any judgment and grant a new

trial if the interest of justice so requires.” Fed. R. Crim. P. 33(a). The determination of

whether to grant a new trial is left to the discretion of the district court. United States v.

Cimera, 

, 458 (3d Cir. 2006). Therefore, we generally review a ruling on a

motion for a new trial under the deferential “abuse of discretion” standard. United States

v. Brown, 

, 511 (3d Cir. 2010). “We have explained that a district court

abuses its discretion if its decision rests upon a clearly erroneous finding of fact, an errant

conclusion of law or an improper application of law to fact.” 

marks omitted). “[T]he district court’s latitude on a new trial motion is broad when the

reason for interfering with the jury verdict is a ruling on a matter that initially rested

within the discretion of the court, e.g. evidentiary rulings … .” Klein v. Hollings, 

, 1289-90 (3d Cir. 1993).




       2
         The District Court had jurisdiction under 18 U.S.C. § 3231. We exercise
jurisdiction pursuant to 18 U.S.C. § 3731.
                                               6
       Federal Rule of Evidence 404(b) provides a general prohibition on character

evidence and limits the permissible uses of such evidence:

       Evidence of a crime, wrong, or other act is not admissible to prove a
       person’s character in order to show that on a particular occasion the person
       acted in accordance with the character. … This evidence may be admissible
       for another purpose, such as proving motive, opportunity, intent,
       preparation, plan, knowledge, identity, absence of mistake, or lack of
       accident.

In recognition of the fact that a jury might place undue weight on evidence of past

wrongs, American courts have long excluded it. United States v. Davis, 

,

440 (3d Cir. 2013). “The risk is that jurors will focus on evidence of prior acts, believing

that someone with a criminal record cannot change and discounting any evidence to the

contrary.” 

“The government knows this, and we do too. Although the

government will hardly admit it, the reasons proffered to admit prior bad act evidence

may often be potemkin village, because the motive, we suspect, is often mixed between

an urge to show some other consequential fact as well as to impugn the defendant’s

character.” United States v. Sampson, 

, 886 (3d Cir. 1992).

       In light of the potential for prejudice that inheres in such evidence, and the mixed

motives that can accompany a request for its admission, “we also require care and

precision by the district court in ruling on the admission of prior act evidence for a non-

propensity purpose.” United States v. Caldwell, 

, 277 (3d Cir. 2014). As

relevant here, a district court must engage in a two-step analysis when considering

whether to admit prior convictions under Rule 404(b). 

. First,

it must assess whether the conviction is logically relevant to one of the permissible


                                              7
purposes identified by the rule. 

if the prior conviction is relevant to

such a purpose, a district court must then apply Federal Rule of Evidence 403 and assess

whether “the probative value of the evidence outweighs its prejudicial effect.” Id.3

       At the first step of the analysis, the government must proffer some “logical chain

of inferences” through which the prior conviction is relevant to one of Rule 404(b)’s

permitted purposes. 

The reasoning must come before, not after, the decision

to admit the evidence. “The district court, if it admits the evidence, must in the first

instance, rather than the appellate court in retrospect, articulate reasons why the evidence

also goes to show something other than character. … The district court must put a chain

of inferences into the record, none of which is the inference that the defendant has a

propensity to commit this crime.” 

repeatedly emphasized the necessity of

the district court placing its reasoning on the record, independent of the government’s

proffer. United States v. Brown, 

, 294 (3d Cir. 2014); United States v.

Lopez, 

, 173 (3d Cir. 2003). “The reasoning should be detailed and on the

record; a mere recitation of the purposes in Rule 404(b)(2) is insufficient.” 

.

       We need go no further. To state the governing rule is to resolve this case. As the

District Court itself recognized, it did not articulate any reason why Lopez’s prior

conviction was admissible under Rule 404(b), nor did it in any way adopt the

       3
        The district court also “must charge the jury to consider the other crimes
evidence only for the limited purpose for which it is admitted.” United States v. Kellogg,

, 199 n.10 (3d Cir. 2007). Here, the Court did provide a limiting instruction,
admonishing the jury to consider the conviction only for the permissible purposes present
in Rule 404(b) and not as propensity evidence.
                                              8
government’s proffered reasoning. It is not our role to supply a post hoc rationale for the

admission of evidence where one is wanting. “[O]ur decisions are … emphatic in

requiring the proponent and the trial judge to articulate, with precision, a chain of

inferences that does not contain a propensity link.” 

(emphasis

added). To its credit, the District Court recognized its error in failing to address the

important issues presented by the admission of Lopez’s prior conviction and acted well

within its discretion in granting a new trial.

       The government’s argument to the contrary is primarily focused on the merits –

that is, the contention that the 2001 conviction is admissible under Rule 404(b). See

United States v. Givan, 

, 461 (3d Cir. 2003) (discussing the relevance under

Rule 404(b) of prior drug distribution offenses). That may be true, and the grant of a new

trial does not foreclose that possibility. But we will not pass on that question before the

District Court conducts its own analysis and places its reasoning on the record. We

express no opinion as to the government’s arguments on the merits of its in limine

motion, which are properly addressed to the District Court in the first instance.4


       4
         The government also argues that the District Court was without authority to grant
a new trial because the issue was “not raised by the defendant” in his motion for new
trial. (Opening Br. at 21.) That contention is unpersuasive. Lopez’s motion for a new
trial addressed a single issue – the admission of his 2001 conviction. Although he
focused his argument on the merits of the decision to admit the conviction rather than the
District Court’s failure to justify its decision, he repeatedly referred to the Court’s lack of
support for its decision and cited our precedent establishing the proper two-step
procedure for the admission of prior convictions under Rule 404(b). In his motion, Lopez
emphasized that the Court had “generally granted” the government’s in limine motion
(App. at 37), and in a supporting memorandum of law, Lopez noted that the Court “did
not provide analysis of the Court’s decision granting the government’s January 20, 2012
motion in limine.” (App. at 46.) In his memorandum, Lopez further noted that the
                                                 9
III.   CONCLUSION

       For the foregoing reasons, we will affirm the District Court’s order granting

Lopez’s motion for a new trial.




Court’s second opinion also “ordered the admission of Mr. Lopez’s 2001 Delaware state
felony drug conviction in conclusory fashion without a detailed analysis or specific
rationale for the decision.” (App. at 47.)
