A jury convicted appellant Edward L. Robinson of two first-degree felony and premeditated murders while armed, along with armed robbery, armed kidnaping, and related offenses. The trial judge sentenced Robinson to life imprisonment without parole for the murders and lesser prison terms for the other crimes. The main issue in this appeal is whether Robinson made a prima facie showing of unconstitutional discrimination in the selection of his jury, necessitating further judicial inquiry, when he objected to the prosecutor’s peremptory challenge of a,young black male juror who had answered no questions during the voir dire. While we agree with Robinson that a peremptory challenge motivated even in part by considerations of race or gender is contrary to the principles of equal protection enunciated in
Batson v. Kentucky,
I.
A. The Batson Challenge and the Trial Judge’s Ruling
Following a lengthy voir dire of the prospective jurors, as the parties readied themselves to exercise their peremptory challenges, the trial judge called counsel for both sides to approach the bench. There the judge cautioned counsel to be mindful of their obligations under Batson and subsequent Supreme Court decisions not to strike jurors on account of their race or gender. If a pattern or other indicia of discrimination emerged, the judge warned, he would intervenе and take appropriate measures. Midway through the process, the judge did just that. Remarking that “six' of the government’s *678 eight strikes have been against blacks and six of the defendant’s eight strikes have been against whites,” the judge expressed his concern that white jurors were being struck disproportionately and would be entirely excluded from the jury if the pattern continued. (It appears that out of the first thirty-two jurors, eleven were white (and the rest were black), meaning that only three white jurors were left when the judge spoke up.) In response, Robinson’s trial counsel 2 disclaimed any intent to discriminate and cоmplained that the prosecutor appeared to be aiming his strikes at “young blacks.” Observing that age is not a prohibited consideration in jury selection, the judge discounted this charge. With a warning that he would scrutinize the remaining strikes “very carefully,” the judge then permitted jury selection to proceed.
All told, the government used its initial ten peremptory challenges to strike six black female, two white female and two black male jurors. For the alternate juror seats, the government exercised an additional strike against a white male. The defense peremptorily struck two black females, four white females, three white males, and one black male, and did not exercise any of its allotted additional strikes.
At the end of the process, the prosecutor offered to make a record of the reasons for each of the government’s peremptory strikes, even though the defense had not yet made an express
Batson
challenge. In response, the judge noted that this court had held in
Baxter v. United States,
Robinson’s counsel then decided to make the Batson challenge that is at issue in this appeal. While “we have blacks and whites on the jury 3 [and] mostly females, 4 ” counsel stated, “we have nobody who is in my client’s demographic group, we have no young black males.” Charging that the prosecutor had struck “the only people who could possibly be considered to be in my client’s circle,” counsel “ask[ed] for an explanation of that.” Pressed to be more specific, defense counsel identified two young black male jurors whom the prosecutor had struck, Juror 754 and Juror 627. Robinson’s counsel admitted that he could not credibly contest the strike of Juror 754, who during the voir dire had expressed the belief that police in Illinois had murdered his brother. But counsel demanded an explanation for the prosecutor’s strike of Juror 627, an 18-year-old black male who worked as a salesperson and lived in Northwest D.C. (not in the vicinity of the charged crimes). Because this juror had answered no questions during the voir dire, counsel emphasized, the prosecutоr knew nothing else about him on which to base his strike. Moreover, counsel added, “there was a pattern,” in that eight out of the government’s first ten strikes were against black jurors.
*679 Finding these arguments unpersuasive, the trial judge ruled that defense counsel had not made a prima facie showing of intentional discrimination. The judge discounted the significance of the “pattern” that counsel identified, noting that any suggestion that the prosecutor attempted to exclude blacks from the jury was not borne out in light of the jury’s ultimate makeup — that is, the judge stated, “you still have 10 black jurors.” The judge accordingly declined to accept the prosecutor’s repeated offer to take just a few minutes to state the reasons for his strikes on the record. 5 Instead, the judge suggested, the government was free to submit an affidavit or other written statement memorializing those reasons, in case the court of appeals disagreed with his ruling. Three weeks later, as the trial was nearing its end, the government submitted a “Memorandum Regarding Peremptory Strikes,” in which it set forth the reasons for each of its strikes. Regarding Juror 627, the Memorandum explained that “[h]e was struck because of his young age. The government was looking for an older and more experienced juror.” 6 Upon receiving the Memorandum, Robinson did not renew his Batson challenge, and the trial judge did not return to the issue.
B. Discussion
1. Mixed Motives and Batson
The Constitution prohibits purposeful discrimination on the basis of race or gender in the exercise of peremptory challenges to prospective jurors.
Batson,
Robinson charged the prosecution with striking Juror 627 for a combination of three reasons: the juror’s race, his gender and his age. Although Robinson does not dispute that “age-based peremptory strikes are constitutionally permissible,”
Baxter,
Past
Batson
cases in this court mostly have presented uncomplicated, single-motivation claims that potential jurors were excluded
solely
on account of their race or their gender. Recently, in
(Leon) Robinson,
we confronted a mixed motivation claim that black female jurors specifically were targeted for exclusion because of their race and their gender. Neither race nor gender alone was sufficient to explain the strikes in
(Leon) Robinson,
but the two factors in combinatiоn did appear sufficient to do so. We held that, just like peremptory strikes motivated by racial or gender bias alone, strikes motivated by those two impermissible reasons in combination are unconstitutional and subject to
Batson
challenge.
The mixed motivation issue that this court has not previously decided is whether a peremptory strike that is only partially motivated by impermissible bias (racial and/or gender in nature) is also subject to
Batson
challenge.
9
But if, for this court, that precise issue is one of first impression, then logic, common sense, and the decisions of numerous other courts leave us in little doubt as to its proper resolutiоn. As a matter of logic and common sense, who would deny that a policy of, say, striking young black jurors while permitting young white jurors to serve would be racially discriminatory? To justify such strikes as solely age-based would be transparently pretextual, even if the strikes were age-based in part. And “[i]n the realm of constitutional law, whenever challenged action would be unlawful if improperly motivated, the Supreme Court has made it clear that the challenged action is invalid if motivated in part by an impermissible reason.... ”
Howard v. Senkowski,
a defendant need not show that a prosecutor’s strikes were motivated solely by racial or gender bias, to the exclusion of all other considerations. Such a requirement would render Batson a virtual nullity and divorce it from the real world of jury selection, for the motivations behind peremptory strikes are seldom so crystallized and singular. Mixed motives are the norm. However, even if the prosecutor acted from mixed motives, some of which were non-discriminatory, his actions deny equal protection and violate Batson if race or gender influenced his decision. A peremptory challenge may not be based even partially on an unlawful discriminatory reason.
We now hold that even where the exclusiоn of a potential juror is motivated in substantial part by constitutionally permissible factors (such as the juror’s age), the exclusion is a denial of equal protection and a Batson violation if it is partially motivated as well by the juror’s race or gender. Accordingly, we hold that appellant Robinson raised a cognizable Batson challenge when he charged the prosecutor with purposefully striking Juror 627 because he was a “young black male.” If the prosecutor in fact was influenced by Juror 627’s race or gender, the strike was unlawful even if the juror’s youth, a legitimate consideration under current law, was the predominant factor in the prosecutor’s calculus. 12
*682 2. Prima Facie Case
The Supreme Court has outlined a three-step procedure for trial courts to follow in evaluating a defendant’s (or other party’s) claims of unconstitutional discrimination in the exercise of peremptory challenges.
See (Leon) Robinson,
The trial judge in this case rejected Robinson’s
Batson
claim on the ground that Robinson did not succeed at the first step in making a prima facie showing of racial or gender discrimination. In asking us to remand for a full hearing on his claim, i.e., performance of step three, Robinson argues that whether he made the requisite prima facie showing at step one is now a moot point because the government proceeded anyway to step two by proffering non-discriminatory reasons for its strikes in a written filing. That action was not enough to render the first step moot, however. It is true that “[o]nce a prosecutor has offered a race-neutral [and gender-neutral] explanation for the peremptory challenges
and the trial court has ruled on the ultimate question of intentional discrimination,
the preliminary issue of whether the defendant had made a prima facie showing becomes moot.”
Hernandez, supra
footnote 7,
Turning, now, to the merits, our review of the trial judge’s ruling is
de novo,
for whether a defendant has made out a prima facie case “is a question of law, namely, whether the voir dire record of the government’s peremptory strikes, as shown by the defendant, raised ‘the necessary inference of purposeful discrimination.’ ”
Little, supra
footnote 5,
According to Robinson, his prima facie case of mixed motive discrimination in the prosecutor’s peremptory removal of Juror 627 rests on just two facts: (1) Juror 627 was the only person on the panel who was, like Robinson himself, a young black malе (other than Juror 754, who Robinson conceded was struck for valid reasons); and (2) Juror 627 answered no questions during voir dire, so the prosecutor presumably *684 knew nothing about him other than his race, gender, age, place of employment, and residential address. 14 This is a bare bones showing; in our view it is too meager a showing, even by the lenient and flexible standard that we apply, to give rise to an inference that the prosecutor struck Juror 627 for reasons, in part, of race and/or gender.
By itself, the exercise of a single strike against the only prospective juror who was simultaneously young, black and mаle has little probative value; the numbers involved are too small to have statistical significance.
Cf. Nelson v. United States,
In other respects, Robinson’s showing plainly was insufficient. He points us to no pattern of strikes suggestive of racial or gender bias — no sign, for example, that the prosecutor exercised a disproportionate number of strikes against black male jurors generally, or that the prosecutor failed to strike similarly situated young jurors who were not black or male.
16
At
*685
trial, Robinson cited the fact that eight of the prosecutor’s ten initial strikes were against potential jurors who were black, but that statistic signifies nothing unless it is compared to the proportionate representation of black jurors in the entire panel.
Jefferson,
From the preceding discussion, we conclude as a mаtter of law that Robinson did not make out a prima facie case of purposeful discrimination against young black male jurors. Not much more would have been needed for a prima facie case to have been made, for the requirements of a pri-ma facie case are comparatively modest. But on the facts presented to the trial judge, we hold that he committed no legal eiTor in rejecting Robinson’s Batson challenge at the threshold.
II.
Although we uphold Robinson’s convictions, we remand for re-sentencing. Pursuant to D.C.Code § 22-2404.1(b), (c) (1981),
18
the trial judge imposed enhanced sentences on each of thе murder counts of life imprisonment without parole (LWOP) on the basis of aggravating circumstances, some of which were neither found by the jury nor coextensive with its verdicts. As the government concedes, re-sentencing therefore is required by our decision in
Keels v. United States,
Additionally, while the trial judge properly imposed a sentence on each count of which Robinson was found guilty, the felony murder convictions should be vacated on rеmand because they merge with their corresponding premeditated murder convictions.
See Thacker v. United States,
So ordered.
Notes
. Robinson's only other claim of trial error relates to the judge’s refusal to give the so-called "missing evidence” instruction,
see
CRIMINAL JURY INSTRUCTIONS FOR THE DISTRICT OF COLUMBIA No. 2.41 (4th ed.1993), based on the government’s failure to produce the shirt worn by the victim whom Robinson was accused of shooting and then robbing. Even if we assume for the sake of argument that the condition of the shirt (specifically, Robinson argues, the absence of a pocket or of blood stains on the pocket) would have been relevant and material to the dispute over whether Robinson robbed the victim, the testimony did not show that the missing shirt was peculiarly available (or, indeed, available at all) to the government.
See Thomas
v.
United States,
. Robinson is represented by different counsel on appeal.
. The judge later stated for the record that ten out of the twelve "regular jurors" (i.e., not counting the alternates) were black.
.Neither the parties nor the judge undertook to state more precisely the gender make-up of the jury selected or of the venire as a whole.
. In the interest of efficiency (and protecting against the possibility of a reversal on appeal), the judge could have accepted the prosecutor’s offer to state his reason for striking Juror 627 and then could have made ruling on whether the stated reason was genuine or pretextual.
See Johnson v. California,
— U.S. -, -,
. As to Juror 754, the other black male juror identified by defense counsel, the govern-merit’s Memorandum provided the following explanation:
This juror stated that the police had apparently arrested his brother for no reason in Illinois. A few weeks later, while the brother was in jail, he was beaten to death. The juror believed that the police were responsible for the beating. The government struck this juror out of concerns that the juror may have been unable to put aside his feelings about his brother’s death during the trial.
. Discrimination on the basis of ethnicity is likewise prohibited.
Hernandez v. New York,
. In this opinion, we employ the terms "Bat-son challenge” and "Batson violation” as convenient shorthand applicable to any unconstitutional discrimination in jury selection, whether or not the discrimination was based on race.
. As the trial judge in this case correctly noted, we did not reach the mixed motivation claim in
Baxter.
In that
pre-J.E.B.
case, the appellant arguеd that the prosecutor had violated his constitutional rights by striking potential jurors on the basis of age and sex. We concluded that neither claim had been preserved.
Baxter,
. See, e.g.,
Gattis v. Snyder,
. As this court also explained in (Leon) Robinson, mixed motivation analysis should not be confused with the recognition of new and narrowly defined "suspect categories” or "cognizable groups” for equal protection purposes. Id. at 1284. Thus, the рresent case does not require us to decide whether "young black males” constitute a unique "cognizable group,” and we do not do so. The critical question under Batson is not that, but simply whether the purposeful exclusion of young black males from jury service involves racial and/or gender discrimination.
. In accordance with mixed motivation principles followed in other contexts, most courts have held it possible for a prosecutor to overcome a
Batson
challenge and save peremptory strikes tainted by racial or gender bias by proving that the same strikes would have been еxercised for race-and gender-neutral reasons in the absence of the improper motive.
Howard,
. Robinson cites our statement in
Epps
that "when, in the absence of. a prima facie showing, a party nonetheless defends against a
Batson
allegation and proffers race-neutral reasons for having removed a juror and does everything that would be required if the opposing party had in fact presented a prima facie case, the question of whether a prima facie showing has been made ‘is no longer relevant.’ ”
. Robinson notes that he also "is entitled to rely on the fact, as to which there can be no dispute, that peremptory challenges constitute a jury selection practice that permits those to discriminate who are of a mind to discriminate.”
Batson,
. We do not retreat from our stаtement that even one purposefully discriminatory strike is unconstitutional and, if proven, entitles the defendant to relief. It is a separate question whether the inference of purposeful discrimination can be drawn with respect to a single strike.
.According to the government's Memorandum Regarding Peremptory Strikes, there was at least one young juror (a black female whose precise age was not stated) whom the government did not strike. Robinson might have strengthened his prima facie showing by pointing this fact out to the trial judge. (In its Memorandum, the government said it allowed this juror to remain on the jury for sеveral reasons: "she was forthright when she answered questions at the bench and she appeared to be very thoughtful,” "her godfather was a homicide detective and ... her mother was a police officer,” and "[gjiven these relationships, the government felt that it was unlikely that she would bring to the jury any *685 preconceived negative views about police officers.”)
.This would be a different case had Robinson’s trial counsel not conceded the propriety of the prosecutor’s strike of Juror 754 and instead pointed out that the prosecutor had used 20% of his strikes (2 of 10) disproportionately to exclude young black males who constituted only 6% (2 of 32) of the potential jurors.
See (Leon) Robinson,
. Section 2404.1 is codified now at D.C.Code § 22-2104.01 (2001).
. The trial judge complied with the law as it stood at the time of Robinson's sentencing; the decisions in both Keels and Apprendi were issued subsequently.
