**384The defendant, Anthony Robertson, appeals from his convictions of murder in the first degree, armed robbery, and carrying a firearm without a license. He argues that he did not receive a fair trial because eyewitnesses improperly identified him in court; the prosecutor misstated evidence in closing argument; the judge erred in declining to question jurors about potential racial bias; the Commonwealth improperly excluded black men from the jury in violation of Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986), and Commonwealth v. Soares, 377 Mass. 461, 387 N.E.2d 499, cert. denied, 444 U.S. 881, 100 S.Ct. 170, 62 L.Ed.2d 110 (1979) ; cellular telephone (cell phone) records that should have been suppressed were introduced; hearsay testimony was improperly admitted; a police officer offered extensive irrelevant testimony about the condition of the apartment where the defendant was arrested; and voluntary manslaughter is the degree of guilt most consonant with justice. The defendant also submitted a separate brief, pursuant to Commonwealth v. Moffett, 383 Mass. 201, 418 N.E.2d 585 (1981), arguing that the jury instructions and the prosecutor's closing argument were erroneous and trial counsel was ineffective.1
*257Because the defendant's right to a fair trial as provided by Batson, supra, and Soares, supra, was violated, we vacate the verdicts and remand for a new trial. We address other claims of error that are likely to recur upon retrial.
Background.2 On June 26, 2011, the victim, Aaron Wornum, was with two friends, Erik Hicks and Jason Heard. The victim, who was wearing a necklace with a gold cross, was driving his friends to Hicks's home, through the Dorchester neighborhood in Boston. On the way, the victim said he had to meet a friend to pick up some money that the friend owed to him. The victim stopped the vehicle in a parking lot and spoke to the defendant on a cell phone about where to meet. The victim drove to a nearby **385street and spoke again to the defendant on the cell phone about where to find him. The defendant and his longtime friend, Emmitt Perry, walked around the corner from a nearby street. The victim then told the defendant on the cell phone that the victim saw him. The victim told Hicks and Heard that he saw the person he was meeting and got out of the vehicle.
The victim, the defendant, and Perry spoke briefly and then started arguing, and the defendant or Perry grabbed the victim's shirt. The victim backed away from the defendant and Perry. Hicks got out of the vehicle to help the victim. The defendant drew a gun. The victim then ran to other side of the vehicle, leaving Hicks closest to gun. While the defendant pointed the gun at Hicks, Perry searched Hicks's pockets, taking a pack of cigarettes and two cell phones. The victim asked the defendant what he was doing and to not do this, repeatedly calling the defendant "Ant."3 The defendant fired the gun in the direction of the victim. The defendant and Perry ran around the vehicle, toward the victim, and the defendant fired the gun again. The victim was on the ground when the gun was fired for a third time. At some point during this altercation, Heard ran from the vehicle. Emergency personnel quickly responded to the scene. The victim was pronounced dead at the hospital that evening.
The defendant and Perry fled and went to the house of Tinea Jones. Jones was the mother of one of Perry's children and a friend of the defendant since childhood. According to Jones, the defendant looked scared and paranoid. He took a shower and asked for a ride to a nearby public transit station. A friend of Jones picked up the defendant and drove him to the station.
Discussion. 1. Cell site location information evidence. The defendant argues that the judge erroneously denied his motion to suppress historical cell site location information (CSLI). He alleges that the warrant used to acquire this data lacked probable cause because the underlying affidavit was defective.
The affidavit included the following information. Boston police officers were called to the corner of Sumner Street and East Cottage Street at 9:20 P.M. on June 26, 2011. The victim was lying on the ground, bleeding from the neck and head, suffering from several gunshot wounds. He was pronounced dead twenty-five minutes later at a local hospital. Two witnesses -- identified as **386witnesses nos. 1 and 2 -- told officers that on the victim's way to drive them home, the victim made and received *258several cell phone calls making plans to meet someone. Both witnesses stated that as the victim drove down Sumner Street, two males came into view, and the victim said, "I see you now," stopped the vehicle, and got out. The witnesses provided descriptions of both men. After a very brief time, the men began pushing the victim back toward the vehicle, and both witnesses saw a gun in the hand of one of the men. Witness no. 1 got out of the vehicle to offer aid and saw the man with the gun shoot the victim. The defendant matched the initial descriptions provided by the two witnesses, and later, in a photographic array, witness no. 1 identified the defendant as the man with the gun. The victim's cell phone records revealed that a telephone number ending in 4076 (number 4076) appeared in incoming and outgoing calls seven times in the hours leading up to the shooting, and was the number from which the last call was made that was received by the victim moments before the shooting. During the investigation, a source identified number 4076 as the defendant's telephone number.
We have "applied the requirement of probable cause to the defendant's historical CSLI because ... where the information at issue covered a two-week period, analysis of this information was akin to tracking the defendant's movements for an extensive time period, and constituted a search under art. 14" of the Massachusetts Declaration of Rights. Commonwealth v. Augustine, 472 Mass. 448, 453-454, 35 N.E.3d 688 (2015) ( Augustine II ), citing Commonwealth v. Augustine, 467 Mass. 230, 254-255, 4 N.E.3d 846 (2014) ( Augustine I ), S.C., 470 Mass. 837, 26 N.E.3d 709 and 472 Mass. 448, 35 N.E.3d 688 (2015). See Carpenter v. United States, --- U.S. ----, 138 S.Ct. 2206, 2212, 2216-2217, 201 L.Ed.2d 507 (2018) (seven days of CSLI constituted search under Fourth Amendment to United States Constitution). When considering the sufficiency of a search warrant application, our review "begins and ends with the 'four corners of the affidavit' " (citation omitted). Commonwealth v. Cavitt, 460 Mass. 617, 626, 953 N.E.2d 216 (2011). "In determining whether an affidavit justifies a finding of probable cause, the affidavit is considered as a whole and in a commonsense and realistic fashion...." Id. The affidavit should not be "parsed, severed, and subjected to hypercritical analysis." Commonwealth v. Donahue, 430 Mass. 710, 712, 723 N.E.2d 25 (2000). We evaluate whether the affidavit underlying the warrant application satisfies the probable cause standard required by art. 14 de novo. Commonwealth v. Foster, 471 Mass. 236, 242, 28 N.E.3d 427 (2015).
**387When reviewing the sufficiency of a search warrant application for historical CSLI, we determine whether, based on the affidavit in support of the search warrant, (1) the magistrate had a substantial basis to conclude that a particularly described offense has been, is being, or is about to be committed; and (2) the CSLI being sought will produce evidence of such offense or will aid in the apprehension of a person who the applicant has probable cause to believe has committed, is committing, or is about to commit such offense. Commonwealth v. Estabrook, 472 Mass. 852, 870, 38 N.E.3d 231 (2015). Inferences drawn from the affidavit must be reasonable and possible, but no showing that the inferences are correct or more likely true than not true is required. See Commonwealth v. Matias, 440 Mass. 787, 794-795, 802 N.E.2d 546 (2004) (contraband found in trash of multiunit apartment building examined in whole supplied probable cause to conclude that contraband came from defendant's apartment).
*259The defendant argues that the affidavit was insufficient because it relied primarily on unsourced police information and misrepresented the quality of one of the eyewitnesses as having unequivocally identified the defendant from the photographic array. However, if the portions of the affidavit to which the defendant objects were redacted, the remaining facts nevertheless would satisfy the requirements of probable cause.
The affidavit provided two percipient witness accounts of the shooting and stated that police had found the victim suffering from gunshot wounds, thus satisfying the first requirement for the search warrant. See Augustine I, 467 Mass. at 256, 4 N.E.3d 846 (first requirement for search warrant is satisfied when affidavit demonstrates probable cause that "offense has been, is being, or is about to be committed").
The search warrant also fulfils the second requirement. The defendant does not contest the two witnesses' accounts of the victim meeting with the shooter through a cell phone call, nor that the victim's cell phone records identify number 4076 as the telephone number that the victim called just before his death. Had the affidavit only indicated that the victim was on his cell phone immediately before the murder, speaking with one of the individuals with whom he likely met, and that the last seven calls in his cell phone records were between his cell phone and number 4076, that evidence would be sufficient to establish probable cause to believe the CSLI of the cell phone associated with number 4076 number would provide evidence of the murder. For example, **388in Commonwealth v. Dorelas, 473 Mass. 496, 503, 43 N.E.3d 306 (2016), the search warrant affidavit stated that the defendant had been using his cell phone to argue with an individual in the hours leading up to and immediately prior to the shooting. We held that this information provided a nexus between the shooting and information on the defendant's cell phone, establishing probable cause that it likely contained "evidence of communications both received as well as initiated ... by the defendant that would link [the defendant] ... to that shooting." Id. Therefore, the motion to suppress was correctly denied. Id. at 505, 43 N.E.3d 306.
2. In-court identifications. The victim's friends who were present at the scene of the shooting, Hicks and Heard, each independently identified a photograph of the defendant as the man who shot the victim. Each witness signed his name to the back of the defendant's photograph and wrote "possibly." The defendant argues that the judge, over objection, erred in admitting Hicks's and Heard's in-court identifications because each witness did not make an unequivocal out-of-court identification of the defendant. The defendant relies on our decision in Commonwealth v. Collins, 470 Mass. 255, 261-262, 21 N.E.3d 528 (2014), which prohibits such identifications.4 Collins, however, by its own terms, applies prospectively only to trials beginning after the issuance of that opinion. Id. at 265, 21 N.E.3d 528. Collins was decided after the defendant's trial concluded; therefore, the defendant does not receive the benefit of that new rule in our assessment of his convictions.
*260However, upon any retrial, it will be the judge's task to determine the admissibility of the in-court identifications. See Commonwealth v. Dew, 478 Mass. 304, 315, 85 N.E.3d 22 (2017). All current case law, including our holding in Collins, may apply to that consideration.
3. Voir dire questioning. The defendant, an African-American man, requested that the judge ask potential jurors if the defendant's race would affect the juror's ability to be fair and impartial. The judge declined, stating that race was not an issue in the case because both the defendant and the victim are African-American. The defendant argues this was an abuse of discretion because, had **389the judge asked this question during voir dire, the defendant could have determined "whether a potential juror would be receptive to defense arguments that police prejudice against young African-American men involved in the drug trade negatively affected the quality of the investigation and the ultimate strength of the case."
The judge has "broad discretion" to determine what questions to ask during voir dire. Commonwealth v. Lao, 443 Mass. 770, 777, 824 N.E.2d 821 (2005). Unless "there exists a substantial risk of extraneous issues that might influence the jury," the judge is not required to ask any questions beyond those required by G. L. c. 234A, § 67.5 Id. We have held that such a risk exists as a matter of law in trials involving interracial murder, interracial rape, and sexual offenses against children. Commonwealth v. Lopes, 440 Mass. 731, 737, 802 N.E.2d 97 (2004). The defendant does not request that we expand that rule, nor do we elect to do so at this juncture. The facts of this case do not fall within those enunciated categories, and the defendant presents nothing to suggest that "extraneous issues" might have influenced the jury. Therefore, the judge did not abuse his discretion when he declined to ask a question about racial bias as **390requested by the defendant. However, we reiterate that "a motion to have jurors asked about racial prejudice should usually be granted." Commonwealth v. Ramirez, 407 Mass. 553, 555, 555 N.E.2d 208 (1990). Racial bias can, of course, have an impact on juror *261impartiality, even where the victim and the defendant are of the same race.
4. Batson - Soares challenge. Rule 20 (c) of the Massachusetts Rules of Criminal Procedure, 378 Mass. 889 (1979), permits the Commonwealth and the defendant to exercise peremptory challenges to prevent venire members, declared indifferent by the judge, from being seated on the jury. "The essential nature of the peremptory challenge is that it is one exercised without a reason stated, without inquiry and without being subject to the court's control." Swain v. Alabama, 380 U.S. 202, 220, 85 S.Ct. 824, 13 L.Ed.2d 759 (1965). However, the equal protection clause of the Fourteenth Amendment to the United States Constitution and art. 12 of the Massachusetts Declaration of Rights place limitations on the use of peremptory challenges. See Batson, 476 U.S. at 85-86, 106 S.Ct. 1712 ("Exclusion of black citizens from service as jurors constitutes a primary example of the evil the Fourteenth Amendment was designed to cure"); Soares, 377 Mass. at 486, 387 N.E.2d 499 (art. 12 proscribes "the use of peremptory challenges to exclude prospective jurors solely by virtue of their membership in, or affiliation with, particular, defined groupings in the community" in order to guarantee "the right to a jury drawn from a representative cross section of the community").
The defendant argues that the prosecutor impermissibly used peremptory challenges to exclude black men from the jury, in violation of the Fourteenth Amendment and art. 12. The judge did not find a discriminatory pattern in the prosecutor's peremptory challenges and, as a result, did not inquire about the prosecutor's reasoning. We review the judge's finding that there was no prima facie showing of a discriminatory pattern for an abuse of discretion.
A judge's evaluation of a Batson- Soares objection follows a three-step process.6 First, the burden is on the objecting *262party to make "a prima facie showing of impropriety" that overcomes the **391presumption of regularity afforded to peremptory challenges. Commonwealth v. LeClair, 429 Mass. 313, 319, 708 N.E.2d 107 (1999). Next, if the judge finds that the objecting party has established a prima facie case, the party attempting to exercise a peremptory challenge bears the burden of providing a "group-neutral" reason for the challenge. Commonwealth v. Scott, 463 Mass. 561, 570, 977 N.E.2d 490 (2012). Finally, the judge then evaluates whether the proffered reason is "adequate" and "genuine." Commonwealth v. Maldonado, 439 Mass. 460, 464, 788 N.E.2d 968 (2003). Only if it is both may the peremptory challenge be allowed.
A prima facie showing of impropriety is present when "(1) there is a pattern of excluding members of a discrete group and (2) it is likely that individuals are being excluded solely on the basis of their membership in that group" (quotation and citation omitted). Scott, 463 Mass. at 570, 977 N.E.2d 490. The trial judge evaluates "all of the relevant facts and circumstances" to determine if the objecting party has met that "relatively low bar." Commonwealth v. Jones, 477 Mass. 307, 322, 77 N.E.3d 278 (2017).
We have never established an exhaustive list of relevant factors, but have long considered concerns such as "the number and **392percentage of group members who have been excluded," id., and "whether the challenged jurors are members of the same constitutionally protected group as the defendant or the victim," Commonwealth v. Issa, 466 Mass. 1, 9, 992 N.E.2d 336 (2013). Recently, we noted that "the possibility of an objective group-neutral explanation for the strike or strikes," despite containing elements of the second and third steps of this analysis, "may play a role in the first-step analysis as well." Jones, supra at 322 & n.25, 77 N.E.3d 278. See Commonwealth v. Lopes, 478 Mass. 593, 601, 91 N.E.3d 1126 (2018) (judge did not err in finding no pattern of racial discrimination where prospective juror's "two significant experiences with the law provided a sufficient and obvious basis for the prosecutor's peremptory challenge").
The challenging party need not show much to satisfy this low burden. Maldonado, 439 Mass. at 463 n.4, 788 N.E.2d 968 (objecting party's burden "ought not be a terribly weighty one"). Indeed, "a single peremptory challenge may be sufficient to rebut the presumption, especially where the challenged juror is the only member of his or her protected class in the entire venire" (quotation and citation omitted). Issa, 466 Mass. at 9, 992 N.E.2d 336. The makeup of the venire can be difficult to assess from the bench given that a judge might not necessarily be able to discern the diversity of the jury pool by looking at the court room. Such difficulty, in part, informs why "we urge judges to think long and hard" before they decide not to require an explanation from the *263prosecutor for the challenge. Id. at 11 n.14, 992 N.E.2d 336.
The judge may consider whether some members of the group in question have already been seated on the jury, but that is not dispositive. "[T]o place undue weight on this factor not only would run counter to the mandate to consider all relevant circumstances, but also would send the unmistakable message that a[n] [attorney] can get away with discriminating against some [group members] so long as [that attorney] does not discriminate against all such individuals" (quotation and citation omitted). Jones, 477 Mass. at 325, 77 N.E.3d 278.
At trial, the defendant objected to two of the Commonwealth's peremptory challenges. Each time, the judge found that the defendant did not satisfy his burden in the first step of a Batson- Soares challenge and therefore did not inquire about the Commonwealth's reasons for the exercise of the challenge. When reviewing a judge's decision not to inquire about a party's reason for exercising a peremptory challenge, we may consider the absence of a neutral reason **393apparent in the record. See Jones, 477 Mass. at 324, 77 N.E.3d 278 ("the possibility that [the juror] was struck because of her race is heightened by the fact that the record reveals no race-neutral reason that might have justified the strike").
The Commonwealth used its second peremptory challenge on the first black man who was a potential juror.7 The defendant objected and defense counsel stated, "My client is a black male and this is the first black male to come before the court to be a potential juror." The judge found no prima facie evidence of impropriety, noting that several "people of color" had already been seated on the jury.
We have often noted that a single peremptory strike can be sufficient to support a prima facie case, especially where the juror is the only member of the venire of the particular group. Issa, 466 Mass. at 9, 992 N.E.2d 336. See Snyder v. Louisiana, 552 U.S. 472, 478, 128 S.Ct. 1203, 170 L.Ed.2d 175 (2008), quoting United States v. Vasquez-Lopez, 22 F.3d 900, 902 (9th Cir. 1994) ("[T]he Constitution forbids striking even a single prospective juror for a discriminatory purpose"). The judge's reasoning that there was not yet a pattern fails to consider this well-established principle that one peremptory strike can sustain the objecting party's prima facie case. We have also turned a keen eye toward the use of peremptory challenges on jurors who are members of the same protected class as the defendant. Issa, supra.
Here, the Commonwealth used the peremptory challenge on a juror who, after twenty-one other potential jurors came before the court, was the first of the same race and gender as the defendant. The record offers little insight into what potential neutral reason the Commonwealth might have offered. The juror did not answer any questions on his questionnaire that necessitated further discussion, and he affirmed that he could be fair and impartial. See Sanchez v. Roden, 753 F.3d 279, 303 (1st Cir. 2014) ("we do find it significant that the record fails to disclose any obvious infirmity in [the juror's] background or voir dire answers that would translate to an apparent reason for the Commonwealth's peremptory challenge"). The only additional information about the *264juror that can be gleaned from this record is that he had two children, ages five and eight. He did not indicate that child care problems would **394arise if he were seated. The judge's failure to inquire about the Commonwealth's reason for excluding this juror was, alone, insufficient to warrant a new trial.
The defendant raised a second objection to the Commonwealth's use of a peremptory challenge to exclude a man from the Dominican Republic. The defendant objected, and the parties disagreed about the potential juror's race. The Commonwealth argued that the potential juror was "Hispanic" and the defendant argued that he was black. This highlights the challenges of justly administering the mandates of Batson and Soares. "The usual tools we rely on to measure one's ethnicity, primarily name and appearance, are often deceptive." Commonwealth v. Calderon, 431 Mass. 21, 25 n.2, 725 N.E.2d 182 (2000) (dismissing Commonwealth's argument that peremptory challenge of African-American juror was proper because juror was likely not the only racial minority who could have been seated, simply because "other jurors on the panel 'had surnames which could have been Hispanic' "). See Commonwealth v. Garrey, 436 Mass. 422, 428, 765 N.E.2d 725 (2002) (when ruling on defendant's Soares challenge, judge "expressed doubt that the prospective juror was African-American," but nonetheless asked prosecutor to provide reason for her challenge, aiding in our assessment on appeal).
Discerning whether a juror is a member of a particular protected class is a decision that often must be made by the judge immediately during the jury selection. The judge does not have much information with which to make this determination, and there is often little information in the record for the reviewing court to consider. See Commonwealth v. Obi, 475 Mass. 541, 551, 58 N.E.3d 1014 (2016) (when analyzing claim defendant used peremptory challenge to improperly exclude Muslim juror, "the judge observed that the juror's headscarf was of a type traditionally worn by Muslim women" and was similar to headscarf worn by Muslim victim, thus providing sufficient evidence of prima facie showing that defense counsel improperly exercised challenge on basis of religion); Commonwealth v. Carleton, 36 Mass. App. Ct. 137, 141-145, 629 N.E.2d 321, S.C., 418 Mass. 773, 641 N.E.2d 1057 (1994) (juror surnames may be used as reliable indicia of national origin or ethnicity, but are insufficient to indicate juror's religion).
We confronted an analogous challenge in Commonwealth v. Bastaldo, 472 Mass. 16, 27, 32 N.E.3d 873 (2015), when considering when a judge should instruct the jury about cross-racial identifications. We said, "Because differences in race based on facial appearance **395lie in the eye of the beholder, we shall not ask judges to determine whether a reasonable juror would perceive the identification to be cross-racial." Id. Rather, we held "that a cross-racial instruction be given unless all parties agree that there was no cross-racial identification." Id. We now apply a similar approach to peremptory challenges. Consistent with our cautious jurisprudence when analyzing Batson and Soares challenges, where a juror's membership in a protected class is reasonably in dispute, trial judges, in performing the first step of the Batson- Soares analysis, ought to presume that the juror is a member of the protected class at issue.
The judge observed that the potential juror was "lighter skinned than [the defendant]," and without deciding how to consider the juror's race, the judge asked the Commonwealth to respond to the defendant's allegation of a pattern, but did not *265ask for a neutral explanation for the use of the peremptory challenge.8 The Commonwealth offered the following response:
"The court found there was no pattern up until now. This individual came in. He said there were incidents on his record that he didn't tell the court.[9 ]
"To be perfectly blunt and I'm going to keep my voice down, he didn't seem like the most intelligent guy. He's like a nice enough guy but he didn't seem all that intelligent.
"And, most importantly, I don't consider him African-American. Whether he has African blood in him or not, I have no **396idea. He was born in the Dominican, I consider him Hispanic.
"...
"His client is African-American and the victim in this case is African-American. Okay. That's what the law is. Not, I mean, is every person who was not born in Cambridge, Massachusetts subject to a Soares challenge?
"I mean, that's ridiculous. So, if the court's finding a pattern, I think I've given it a neutral reason for the pattern.
"I'd ask the [c]ourt not to find a pattern at this point."
After the Commonwealth concluded its argument, the judge reiterated that he was "careful not even to inquire" about the Commonwealth's reasons, stating that if he did not find a pattern, he did not have any right to ask for the Commonwealth's reasons.10 The judge ruled that he did not find a pattern so he did not "reach the issue of the truthfulness or the genuineness and the nonracial basis for the challenge."11
*266The judge explained that he did not see a pattern because, in **397part, there were two black women on the jury. This reasoning fails for two reasons. First, the defendant was not challenging the exclusion of all black people from the jury, but specifically black men. "[A]rticle 12 proscribes the use of peremptory challenges to exclude prospective jurors solely by virtue of their membership in a group delineated by race and gender." Commonwealth v. Jordan, 439 Mass. 47, 62, 785 N.E.2d 368 (2003) (no abuse of discretion or error of law where judge found prima facie evidence of pattern of discrimination in defendant's use of peremptory challenges to strike white males). Second, the mere presence on the jury of members of the group at issue is not dispositive whether there is a pattern; the totality of the circumstances must be taken into account. See Sanchez, 753 F.3d at 303 (seating of five African-Americans on jury when juror at issue was challenged did not preclude Batson- Soares challenge).
"Consideration of all relevant circumstances compels the conclusion that the defendant made the limited showing necessary to make out a prima facie showing of discrimination." Jones, 477 Mass. at 326, 77 N.E.3d 278. We conclude therefore that the judge abused his discretion in finding no pattern after the defendant's second objection to the Commonwealth's use of peremptory challenges on black men. Because such an error is structural, carrying the presumption of prejudice, we vacate the convictions and remand the case for a new trial. Id. at 325-326, 77 N.E.3d 278.
So ordered.
