Appellant Maurice W. Morris appeals his convictions 1 by a jury on the grounds that *1119 (1) the trial judge erred in allowing an improper missing witness argument and improper comment on appellant’s post-arrest silence during cross-examination and closing argument, (2) the trial judge erred in refusing to admit evidence of other crimes committed by a third person, and (3) appellant’s conviction for assault with a dangerous weapon merged with the conviction for attempted robbery while armed. We hold that the government did not make a missing witness argument, and we find no reversible error under the circumstances as a result of the prosecutor’s reference to appellant’s post-indictment failure to tell others who were present at the shooting to speak with law enforcement authorities. We also hold that the trial judge did not abuse his discretion in excluding certain evidence of the other crimes of a third person. Accordingly, except for a remand to address the merger of certain convictions, we affirm.
I.
The grand jury returned a nine-count indictment charging appellant with crimes occurring on July 15, 1989. At trial, appellant presented a misidentification defense, admitting that he was at the crime scene but maintaining that the crimes were committed by Maurice Glenmore, who resembled appellant.
Vincent Flythe, the victim of the attempted robbery, testified that on July 15, 1989, he was standing on the corner of 12th and Hamlin Streets, N.E., when three or four masked “boys” ran around the corner, shooting in the air. One of the masked men ran up to Flythe, put a gun to Flythe’s stomach, and pulled the trigger three times. Flythe saw sparks and heard a loud popping noise, but was not shot. Someone said, “give us your money.” Flythe, claiming they were shooting blanks, told Tony Reed, who was using a public telephone nearby, to run. Flythe ran in one direction and Tony Reed ran in another. Flythe heard Tony Reed scream, ran back, and saw Tony Reed lying on the ground. Tony Reed died later that night of four gunshot wounds.
An eyewitness, Octavia Brown, testified that on July 15, 1989, around 9:30 p.m., she was at 3006 12th Street, N.E. She heard gunshots coming from the direction of the corner of 12th and Hamlin. She looked out the window and saw Tony Reed and Antonio Brox running in one direction while Vincent Flythe ran in another. Three “boys” were shooting at the fleeing men. The “boys” were wearing ski masks, and Ms. Brown could see that two of them had guns and that the third held his hands as if he had a gun, although she could not see his gun. One of the masked men stopped in the middle of the street and “kept shooting” at Tony Reed and Antonio Brox, Tony Reed’s cousin. Tony Reed fell to the ground as the shooter continued shooting at Tony Reed’s brother, Randy Reed.
Ms. Brown explained that she was able to see the profiles of the two robbers when they removed their masks for about five seconds as Tony Reed was falling, that the masks were still off when Tony Reed’s brother Randy arrived on the scene, and that the two men pulled their masks down again immediately when Randy Reed arrived. 2 She stated that “[i]t was light enough, [bejcause the streetlights were on,” although the assailants were not standing under a streetlight. She described the shooter as having “[bjrown skin,” with “big ears” and “big lips.” The two assailants in the street were “shortish.” One of the two assailants in the street pulled on the other one’s shoulder, to signal him to leave. The third masked man, whom Ms. Brown described as the tallest of the three, was already running away.
*1120 Ms. Brown identified appellant in a photograph array about two days after the shooting and in a videotape of a lineup about two months thereafter. She also identified appellant in court as the shooter who had been standing in the middle of the street. In court, Ms. Brown was also shown photographs of appellant and Maurice Glenmore, who died in January 1990 and who appellant later argued was the real shooter. Ms. Brown admitted that the men in the two photographs looked similar, with big ears and prominent noses and lower lips. She claimed, however, that she could tell the two apart because one man had a darker complexion than the other. 3
A second eyewitness, Randy Reed, was the brother of the deceased. He testified that while he was running an errand shortly before the shooting, he saw an old brown and yellow car on 10th Street, N.E., and that upon returning from his errand, he saw the same car again on the corner of 12th and Hamlin. While the car was stopped at a stop sign, Randy Reed saw five black males in the car, and he recognized three of them: Eric Forbes was driving the car, and Cary Jackson (“Mac”) and appellant (“Mo Mo”) were seated in the backseat. Reed left to run another errand, and when he returned, he was told that there was shooting going on. Randy Reed ran towards his brother Tony as Tony ran towards him.
Randy Reed saw someone standing in the middle of the street, almost directly in front of 3006 12th Street, shooting at his brother Tony Reed. He saw the shooter’s face for approximately ten seconds, while standing about four or five car lengths aWay. He recognized the shooter as appellant, whom he knew as Mo Mo and had seen in the back seat of the brownish-yellow car. Randy Reed was positive that Mo Mo was the shooter; he had seen appellant approximately thirty to fifty times over the preceding year on the street and in clubs. Although he did not remember the robbers putting on or taking off masks, there was something on top of the shooter’s head that the shooter pulled down over his face as he ran away. He identified appellant in court and from a videotaped lineup as the shooter. When shown a photograph of Maurice Glenmore, Randy Reed said that Glenmore did not look like appellant because of the former’s “facial structures” and smaller head.
Appellant, whose nickname was Mo Mo and who was sixteen at the time of the shooting, testified that on the evening of July 15, 1989, two groups of friends switched cars and he drove off with one group in a tan car, intending to go to a club. Eric Forbes was driving the car, Rico Thomas was the front seat passenger, and appellant, Maurice Glenmore (“Mo”), and Cary Jackson were on the left, center, and right portions of the back seat, respectively. According to appellant, as they passed the corner of 12th and Hamlin Streets, N.E., Glenmore said, “[t]here's Vincent,” and that he was going to rob Vincent Flythe to get money for the club’s entrance fee. Forbes pulled the car into an alley, and everyone except Forbes got out of the car. Appellant testified that Glen-more, Jackson, and Thomas all had guns and that they put on black ski masks. Appellant saw Glenmore, Jackson, and Thomas walk toward the corner of 12th and Hamlin Streets, as appellant and Forbes waited with the car. Appellant heard shots, saw two people running, and saw Glenmore standing in the street, shooting at one of the running men. Glenmore, Jackson, and Thomas returned to the car and removed their masks. Appellant testified that he never intended to commit a robbery.
William Welch, a defense expert witness, testified that if the cartridge shells and the bullets found on the scene came from the same gun, the gun used was probably either a Stoeger Lueger or a Hi-Standard Sport King. However, he did not know whether the cartridge shells and bullets belonged together, and if not, he opined *1121 that approximately thirty-six types of guns could have fired the bullets. 4
Appellant also called several friends who testified that they had seen Glenmore with a German Lueger on several occasions in June and July 1989. Indeed, Andy Williams testified that he had not only seen Glenmore with a German Lueger on several occasions in June and July of 1989, but he had actually seen Glenmore shoot someone with the gun. Nathanial Matthews testified that he, too, had seen Glenmore with a Lueger in June 1989, had seen him use the gun to shoot someone, and knew of robberies that Glenmore had committed. Matthews further testified that although he never had any trouble telling them apart because he knew them, appellant and Glen-more “looked just alike”: they were the same size, and “the only difference” was that one had darker skin than the other. Appellant’s sister also testified that she and appellant’s mother had once mistaken Glenmore for appellant for a few seconds. 5
In rebuttal, Maurice Glenmore’s aunt testified that appellant looked “nothing like” Glenmore because appellant was shorter and his “ears came outward,” while Glen-more’s did not.
II.
Appellant contends that the trial judge erred in not intervening sua sponte when the prosecutor made a missing witness argument and commented on appellant’s post-arrest silence while cross-examining appellant, and in overruling defense counsel’s objection to a similar missing witness argument and comment on appellant’s post-arrest silence during the prosecutor’s closing argument. 6 After the prosecutor com *1122 pleted his initial closing argument, defense counsel explained to the judge that her objection was based on the prosecutor’s use of a missing witness argument (where the witnesses had a Fifth Amendment privilege) and on his comment on appellant’s post-Miranda, 7 silence in that appellant had failed, after he had acquired counsel, to contact witnesses and mount a defense. The judge ruled that he did not interpret the prosecutor’s argument to be a missing witness argument but rather to be a comment on appellant’s claims that Maurice Glenmore had threatened appellant when appellant was in jail. 8 The judge did not explicitly address defense counsel’s claim that the prosecutor had impermissibly commented on appellant’s silence. Appellant’s motion for a mistrial was denied.
A.
It is clear under our recent case law that the prosecutor’s cross-examination of appellant and comments during closing argument did not present a missing witness argument.
9
In
(Claude) Allen v. United States,
We need not decide whether the prosecutor should have sought the trial judge’s approval before asking these questions and presenting his argument to the jury if the prosecutor sought to draw an inference of consciousness of guilt from appellant’s inaction.
12
Even if the prosecutor should have sought prior approval, we find no reversible error.
See Allen, supra,
B.
More problematic are the prosecutor’s references during cross-examination and closing argument to appellant’s post-arrest failure to reveal defense evidence to the authorities.
14
The cross-examination
*1124
concerned appellant’s conduct after his arrest, unlike the cross-examination concerning pre-arrest conduct in
Allen, supra,
The prosecutor’s comments during closing argument were an impermissible reference to appellant’s failure to reveal defense theories to the police or the prosecutor. In
Hunter, supra,
The same rationale that forbids comments on a defendant’s failure to “lay bare [her or his] defense for the prosecutor or the police,”
Hunter, supra,
The court has held that a prosecutor may cross-examine a defense witness concerning that witness’ failure to bring information to the police or prosecutor where such questioning addresses the witness’ credibility.
See Cain v. United States,
The question remains whether the trial judge’s error in overruling the defense objection to the government’s closing argument was harmless.
20
See Hunter, supra,
III.
Appellant also contends that the trial judge erred in refusing to admit evidence of other crimes committed by Maurice Glenmore.
Defense counsel proffered that the testimony of three witnesses would show that Glenmore had committed armed robberies with a Lueger in neighborhoods with which he was familiar, that Glenmore had shot someone from about the same distance that the shooter hit Tony Reed, and that Glen-more had shot Eric Forbes with a Lueger within three weeks after Tony Reed’s murder. This evidence was designed to show that at the time Glenmore had committed the other crimes, he had the type of gun that killed Tony Reed, that Glenmore’s motive on July 15,1989, was robbery, and that Glenmore could hit a target from the distance that Tony Reed was shot. Evidence that Glenmore had shot Eric Forbes was designed to show Glenmore’s consciousness of guilt; because Forbes was present at the scene of the shooting but he did not participate in it, he was a possible witness against Glenmore.
After each proffer the trial judge refused to admit the evidence, reasoning that
Drew v. United States,
The court has not yet decided whether
Drew
may be used defensively, i.e, that it applies to defense evidence regarding third parties’ crimes.
24
See Gates v. United States,
Appellant’s proffered evidence failed to show the necessary clear link between Glenmore’s previous crimes and the crimes with which appellant was charged. Evidence that Glenmore had committed other armed robberies, even robberies in neighborhoods in which Glenmore was well-known, did not tend to show that Glen-more had committed the attempted robbery, murder, and related crimes that occurred on July 15, 1989. Mere opportunity is insufficient.
See Johnson, supra,
The only proffered evidence suggesting that Glenmore’s other crimes were possibly linked to the charges against appellant was the proffered evidence that Glenmore had subsequently shot Eric Forbes, the driver of the car on the night of the shooting. Arguably, this might have shown consciousness of guilt: if Glenmore was the shooter, he may have been trying to remove a potential witness.
But cf. Parks, supra,
But, even if the judge erred, the defense suffered little, if any, prejudice.
See (Larry) Lee v. United States,
Therefore, we agree with the government’s evaluation that, under these circumstances, admission of further “attenuated evidence of Glenmore’s ‘other crimes’ would not have bolstered appellant’s case or diminished the strong case submitted by the government.”
IV.
Finally, appellant contends, and the government agrees, that his conviction for assault with a dangerous weapon, D.C.Code § 22-502 (Repl.1989), merges with his conviction for attempted armed robbery, D.C.Code §§ 22-2901 (Repl.1989), -3202 (Supp.1992).
30
The court has held that armed robbery and assault with a dangerous weapon merge where both offenses are committed against the same victim as part of the same criminal incident.
See, e.g., Harling v. United States,
On appeal, neither appellant nor the government addresses the question of whether, once the conviction for assault with a dangerous weapon merges with the conviction for attempted armed robbery, appellant’s conviction for possession of a firearm during a crime of violence or dangerous offense (assault with a dangerous weapon) merges with his conviction for possession of a firearm during a crime of violence or dangerous offense (attempted armed robbery).
31
Nevertheless, we hold that these two convictions merge because they concern violations of the same statute, D.C.Code § 22-3204(b), by the same actions (placing a gun against Mr. Flythe’s stomach and demanding his money), and there is no indication that the legislature intended to allow multiple sentences in such circumstances.
See Bean v. United States,
Although the court has rejected the use of a fact-based test for merger where a defendant is convicted under two or more statutes and adopted the
Block-burger
test,
32
Byrd v. United States,
598
*1130
A.2d 386, 389-90 (D.C.1991) (en banc), a fact-based approach remains appropriate where a defendant is convicted of two violations of the same statute.
See Joiner v. United States,
Accordingly, we remand the case to the trial court to vacate appellant’s convictions for assault with a dangerous weapon and the single count of possession of a firearm during commission of the assault with a dangerous weapon, and we otherwise affirm.
Notes
. Appellant was indicted for attempted robbery while armed, D.C.Code §§ 22-2902 (Repl.1989), -3202 (Supp.1992), first degree murder while armed, id. §§ 22-2401 (Repl.1989), -3202 (Supp.1992), carrying a pistol without a license, id. § 22-3204(a), assault with intent to murder while armed (two counts), id. §§ 22-503, -2403 (Repl.1989), -3202 (Supp. 1992), and possession of a firearm during a crime of violence or dangerous offense, id. § 22-3204(b). The jury acquitted appellant of first degree murder while armed and assault *1119 with intent to murder Vincent Flythe, but found him guilty of second degree murder while armed, assault with a dangerous weapon (of Vincent Flythe), attempted robbery while armed (against Flythe), carrying a pistol without a license, and three counts of possession of a firearm during a crime of violence (murder, assault on Flythe, and attempted robbery while armed).
. During this time, the third masked man was further away from Ms. Brown, standing near the telephone booth close to the corner of 12th and Hamlin Streets.
. Detective Randall testified that during the photograph array Ms. Brown had identified as the second robber a man who was deceased at the time of the shooting and attempted robbery. The detective also testified that he had never heard Glenmore mentioned as a suspect.
. Mr. Welch also testified that he had visited the crime scene at about 9 p.m. one night, almost two years later, and found that he could not easily discern the features of persons he knew from a distance of more than twenty-five feet.
. To show that Randy Reed could not have seen the shooter’s face — because the shooter turned and ran before Randy Reed arrived on the scene — the defense also called David Brox. Brox was Tony Reed's cousin and was at 3006 12th Street on the night of the shooting. Brox testified that he never saw the shooter remove his mask. (He described the mask as a light brown stocking cap which had a knot on top and was the type of mask which flattens facial features but still leaves the face visible.) When the shooter turned and ran, Brox could hear Randy Reed but he could not yet see him. Brox admitted, however, that he may have missed something while he was running up or down stairs.
. During the prosecutor’s cross-examination of appellant, the following exchange occurred:
[THE PROSECUTOR:] After you got arrested did you ever talk to Eric Forbes?
[APPELLANT:] No.
[THE PROSECUTOR:] You never did?
[APPELLANT:] No.
[THE PROSECUTOR:] Did you ever try and get in touch with him?
[APPELLANT:] No.
[THE PROSECUTOR:] When you knew you were charged with the murder you didn’t commit, right?
[APPELLANT:] Yes.
[THE PROSECUTOR:] And you knew Eric Forbes could tell the police you didn't do it, correct?
[APPELLANT:] Yes.
[THE PROSECUTOR:] You never tried to call Eric Forbes?.
[APPELLANT:] No.
[THE PROSECUTOR:] Rico Thomas, did you ever try to talk to him about it?
[APPELLANT:] No.
[THE PROSECUTOR:] Mac? [Cary Jackson]
[APPELLANT:] No.
In closing argument, the prosecutor told the jury:
Then he’s arrested, he’s an innocent man and he’s arrested. Now put yourself in his shoes. You didn’t commit a crime, what are you going to do? Aren’t you going to call up, does it take any great mind to figure out I’m going to call up Eric Forbes, my friend, Eric Forbes, I’m going to say, Eric, you were there, how about getting me out of this jam. See, I’m being charged with first degree murder and I don’t like being in jail. It’s not fun. How about calling — how about telling the police who really did the murder? How about calling up the prosecutor, Mr. Delaplaine, or the U.S. Attorney’s office or anybody—
Defense counsel objected, and asked to approach the bench, but the trial judge overruled the objection. The prosecutor continued:
Does he do that, ladies and gentlemen? Does he call anybody up? He told you no, he didn't ask Eric Forbes to make any call for me. I didn't ask Carey Jackson, I didn't ask Rinko [sic] Thomas, I didn't ask any of those guys to say I didn’t do it. That was his testimony, ladies and gentlemen.
And is that what you would have done if you were an innocent man in his situation?
.
Miranda v. Arizona,
. The judge explained that the prosecutor “was rather commenting on the proposition that with all these guns, with all these other matters that [appellant] testified to, he chose to just merely be threatened by Glenmore.... [This was] a comment on the evidence."
.
See generally Graves v. United States,
.In Allen, supra,
[djuring cross-examination, the prosecutor sought to show that if Allen had killed Manning justifiably in self-defense, then it would have been logical for him to do what he could to enable the authorities to find out what really happened. Specifically, the prosecutor suggested that an innocent man would have ... requested Gerard to stay in touch.
Id.
. In any event, appellant could have brought out on re-direct examination, and thereafter during closing argument, that the people in the car with him were either deceased or unlikely to contact authorities for fear of incriminating themselves.
See Allen, supra,
. In
Allen, supra,
. Even though an improper missing witness inference that addresses the defendant’s credibility, "where the defendant's credibility is a key issue, ... will ordinarily require reversal,"
Thomas v. United States,
. Neither appellant nor the government cites
(William) Hill v. United States,
. The prosecutor’s reference to appellant’s failure to call the police immediately after the shooting was a comment on appellant’s pre-arrest, pre-indictment silence, and appellant does not claim on appeal that those questions were erroneously allowed by the trial judge.
. In
Hunter,
the prosecutor stated during closing .argument: “Here’s somebody charged in an indictment ..., which normally you would not take lightly.... And yet, he doesn’t tell the Government, didn’t tell the police, doesn’t tell anybody, hey, you don’t understand how this all came about.”
. We agree with the government’s reading of the prosecutor’s statements in closing argument to mean that appellant did not ask Eric Forbes to call the police or prosecutor, not that appellant did not himself call the authorities. After defense counsel’s objection was overruled, the prosecutor moved on in closing argument to ask the jury: “why doesn’t he [appellant] tell anybody who really did the crime?" Appellant does not challenge this statement on appeal. Appellant contends, however, that the argument that appellant should have had acquaintances contact the police suggested that appellant had a burden of proof. We disagree.
See Gray v. United States,
. The government’s attempts to distinguish
Hunter
are unpersuasive. It is inaccurate to suggest that the prosecutor simply "focused on appellant’s silence vis-a-vis his friends.” The government’s reliance on
Grancorvitz v. Franklin,
. The court observed in Cain, however, that "in certain contexts, a prosecutor is precluded from commenting upon or inquiring into the reasons underlying a witness’ delay in coming forward with exculpatory evidence.” Id. at 1006 (citation omitted).
.The government argues that a plain error standard applies because the relevant portion of the prosecutor’s closing argument was based on his cross-examination of appellant, and defense counsel failed to object to the questions on cross-examination. In fact, the closing argument went beyond the cross-examination by expanding on the idea that appellant also did not ask Eric Forbes to contact the authorities on appellant’s behalf. The defense objected to the relevant part of the closing argument.
The government also mistakenly maintains that the plain error standard applies to the closing argument because defense counsel did not object on the grounds that the prosecutor had commented on appellant's failure to give defense information to the prosecutor. In fact, defense counsel stated that her objection to the closing argument rested on two grounds: use of an impermissible missing witness argument and use of an "argument that my client, at a time when he had counsel, could have called, contacted people, and at that time put forward a defense.” Accordingly, we apply the harmless error standard.
. In
Hunter,
however, defense counsel did not object at trial to the prosecutor’s closing argument, implying that counsel had not perceived any prejudice arising from the argument.
Hunter, supra,
. In
Singleton,
the improper cross-examination concerning the defendant’s post-arrest silence arose where the defendant claimed self-defense and the case was essentially a credibility contest between the defendant and the complainant; other witnesses had not observed the entire incident.
.
See Easton v. United States,
. In its brief the government submits that “there is no principled difference between the government’s attempt to introduce other crimes evidence against a defendant, and a defendant’s attempt to introduce other crimes evidence against a third person.”
.
See Beale, supra,
.See Shepard, supra,
. Appellant’s suggestion that the evidence that Glenmore shot Forbes was admissible under the common plan or scheme exception is meritless.
See Easton, supra,
. When asked when he had seen Glenmore with the Lueger, Mr. Matthews answered, ”[h]e [Glenmore] shot at somebody with it [the gun], and I seen him." When asked "July 15, 1989, did you see Maurice Glenmore with that Lueger?’’, the witness answered, "When Eric Forbes got shot.” Matthews also testified that Glen-more and Rico Thomas once borrowed a car from Matthews and others “and they robbed somebody in our car, and we got shot at.” The prosecutor’s cross-examination of Matthews reemphasized the information about Glenmore’s other crimes. The prosecutor asked, ”[a] moment ago you said it was something about a day Eric Forbes was shot ... Is that one of the times ... in June of 1989?” Matthews did not clearly answer this question. The prosecutor asked whether Rico Thomas had told the witness that Glenmore still possessed the Lueger on July 15, 1989. The witness answered "Yes, because they had just robbed somebody." In addition, Andy Williams testified that he saw Glenmore shoot someone with a Lueger.
The judge also allowed defense evidence concerning Glenmore’s possession of a Lueger. The judge noted that the evidence had passed the threshold of
Johnson, supra,
.A reasonable jury could reasonably find appellant guilty as an aider and abettor even if it believed that Glenmore was the actual shooter. The jury could have believed that appellant was one of the three masked robbers, but not the shooter, or, possibly, that appellant stayed in the car but assisted in the robbery by serving as a lookout.
Cf. Parks, supra,
. At sentencing, the judge stated that he was "not going to handle the merger problems,” but was going to give concurrent sentences for assault with a deadly weapon and attempted armed robbery partly because he believed that those convictions might merge.
. At sentencing, the prosecutor stated that ”[i]t’s the Government's position that the only charges which merge for which the Defendant cannot be given consecutive time for would be the three counts of Possession with [sic] a Firearm During the Crime of Violence.”
. The Blockburger test provides that:
[w]here the same act or transaction constitutes a violation of two distinct statutory pro *1130 visions, the test to be applied to determine whether there are two offenses or only one is whether each provision requires proof of a fact which the other does not.
Id.
. A conviction of possession of a firearm during a crime of violence or dangerous offense will not merge with a conviction for the relevant dangerous offense.
See e.g., Freeman v. U.S.,
