    Indictments found and returned in the Superior Court
    Department on February 18, 2010.
    A motion to dismiss was heard by Richard J. Carey, J.; a
    renewed motion to dismiss was considered by Cornelius J.
    Moriarity, II, J.; and the cases were tried before Constance M.
    Sweeney, J.
    Donald A. Harwood for the defendant.
    Jane Davidson Montori, Assistant District Attorney, for the
    Commonwealth.
    SPINA, J.     The defendant was convicted of deliberately
    premeditated murder and possession of a class B substance.      On
    2
    appeal he asserts error in (1) the denial of his motion for a
    required finding of not guilty; (2) the denial of his motion to
    dismiss based on Mass. R. Crim. P. 36, as amended, 
    422 Mass. 1503
    (1996) (rule 36); (3) the denial of his motion to dismiss
    for delayed disclosure; (4) the judge's failure to declare, sua
    sponte, a mistrial based on alleged jury tampering; and (5) the
    judge's instruction pursuant to Commonwealth v. Ciampa, 
    406 Mass. 257
    (1989).    The defendant also seeks relief under G. L.
    c. 278, § 33E.   We affirm the convictions and decline to
    exercise our authority under G. L. c. 278, § 33E, to reduce the
    conviction of murder to a lesser degree of guilt or order a new
    trial.
    1.     Background.   The jury could have found the following
    facts.   Shortly before midnight on January 28, 2010, Angel
    Gonzalez (Angel) called the defendant on his cellular telephone
    to arrange a purchase of cocaine.    Angel and Luis Soto then
    drove to a night club in Holyoke where the defendant sold them
    cocaine.    They traveled in a grey four-door 2006 Nissan Altima
    owned by Soto's girl friend.    They then drove to a bar in
    Holyoke, ingesting the cocaine en route.
    At about 12:56 A.M. on January 29, Angel's mother called
    Angel on his cellular telephone and told him that the victim was
    at the Holyoke Medical Center and needed a ride.    Soto, Angel,
    and Angel's brother Felipe left the bar in the Altima.     They
    3
    drove to the hospital and went inside to get the victim.       The
    four men then returned to the bar.     After about one hour they
    all left together.    Angel called the defendant on his cellular
    telephone to arrange another purchase of cocaine.    Angel's
    cellular telephone records showed three calls that connected
    with the defendant's cellular telephone between 1:30 A.M. and
    1:52 A.M.    They drove to the night club to meet the defendant.
    Angel and the victim got out of the car and went inside the
    club.   When they returned, the defendant was with them and the
    three men entered the Altima.
    Soto was driving; Angel was in the front passenger seat;
    the defendant sat behind Soto; Felipe was behind Angel; and the
    victim sat between the defendant and Felipe.    The defendant told
    Soto to drive.    They proceeded down High Street.   The defendant
    directed Soto to turn right onto Essex Street.    The defendant
    pulled out a handgun and shot the victim twice in the left rear
    side of his head.    Soto stopped the car and shifted into the
    "park" position.     Felipe got out of the car and ran toward High
    Street.     Angel got out of the car and stood nearby for a short
    time before running toward High Street.     Soto was the third to
    get out of the car.     He hesitated because he was concerned about
    abandoning his girl friend's car, but then he left and ran
    toward High Street.
    4
    The defendant was the last person to get out of the Altima.
    He walked around the rear of the car, opened the rear
    passenger's side door and fired a third shot into the victim's
    right temple.   He then got into the driver's seat of the Altima
    and sped off.   The defendant turned onto Newton Street where he
    stopped and dumped the victim's body in the road.    In the
    meantime, Felipe, Angel, and Soto made their way to Sam's Food,
    a nearby store on High Street.    The defendant called Angel's
    cellular telephone at 2:04:07 A.M.    The call connected for
    forty-four seconds.   The Altima, driven by the defendant,
    arrived at Sam's Food store shortly thereafter.    The defendant
    left the car there, and left the scene himself.    The others then
    drove away in the Altima.   Soto turned himself in to police the
    next day.
    2.   Motion for required finding of not guilty.    The
    defendant argues that the evidence was not sufficient to convict
    him and that the judge erred in denying his motion for a
    required finding of not guilty.    He contends that Felipe and
    Soto, who testified pursuant to cooperation agreements1 and whose
    1
    Angel Gonzales invoked his privilege against self-
    incrimination in the presence of the jury, at the request of the
    defendant, and did not testify. Without question, the
    prosecutor could not have called Angel to invoke his privilege
    against self-incrimination in the presence of the jury. The
    defendant had no right to proceed in this manner. See
    Commonwealth v. Rosario, 
    444 Mass. 550
    , 557-560 (2005);
    Commonwealth v. Fisher, 
    433 Mass. 340
    , 350 (2001); Commonwealth
    v. Hesketh, 
    386 Mass. 153
    , 157 (1982). There was no perceptible
    5
    murder indictments had been nolle prossed before the defendant's
    trial, gave "perjurious" and "uncorroborated" testimony that was
    legally insufficient to support a conviction.
    He further contends that the evidence "conclusively
    demonstrate[d]" that Felipe was the only person in the car
    positioned to fire a bullet into the right temple of the victim,
    who was sitting immediately to his left.   In this regard he
    cites the testimony of Soto, who heard only one shot fired in
    the car, then turned and saw the victim falling forward.     The
    defendant reasons that this single shot, the only shot Soto
    heard in the car, must have been the one fired into the victim's
    right temple.   He further cites the testimony of Barbara St.
    Amand, a witness who looked out of her apartment window on
    Newton Street after hearing a car come to a screeching stop.
    She saw one man wearing a black hooded jacket, the same type of
    clothing worn by Felipe, go to the rear passenger's side of the
    car and pull something out.   The man then entered the car
    through the door behind the driver, and the car sped away.      The
    defendant contends that St. Amand's testimony establishes that
    two people were involved in the killing -- the driver of the
    car, Soto, and his rear driver's side passenger, Felipe.
    prejudice to the defendant. Indeed this evidence allowed the
    defendant to buttress his theory that Luis Soto and Felipe
    Gonzales killed the victim.
    6
    The defendant asserts that there was no evidence that he
    had a motive to kill the victim and, by contrast, that Angel and
    Felipe went to see the victim about one week before the killing
    to settle a dispute over a large sum of money that the victim
    owed Felipe and Angel.    The victim was not at his apartment but
    a brother of Angel and Felipe took a valuable necklace from the
    victim's girl friend as payment.    When the victim learned what
    had happened he telephoned Angel and told him he was "going to
    kill him and fuck him up."
    When reviewing the denial of a motion for a required
    finding of not guilty at the close of the Commonwealth's case,
    "the critical inquiry . . . must be . . . to determine whether
    the record evidence could reasonably support a finding of guilt
    beyond a reasonable doubt. . . .   [The] question is whether,
    after viewing the evidence in the light most favorable to the
    prosecution, any rational trier of fact could have found the
    essential elements of the crime beyond a reasonable doubt"
    (emphasis in original).    Commonwealth v. Latimore, 
    378 Mass. 671
    , 677 (1979), quoting Jackson v. Virginia, 
    443 U.S. 307
    , 318-
    319 (1979).   In developing his argument, the defendant largely
    has marshaled the evidence in the light most favorable to
    himself.   We reject the defendant's approach.   The jury were not
    required to accept all the testimony of a witness, for example,
    St. Amand; nor are we.    When deciding the denial of a motion for
    7
    a required finding of not guilty, we consider the evidence in
    the light most favorable to the Commonwealth.    In addition, the
    absence of evidence of motive is not material to our inquiry.
    The Commonwealth is not required to prove motive.    See
    Commonwealth v. Brooks, 
    422 Mass. 574
    , 581 (1996).
    Soto testified that as they were driving he heard a
    "detonation" and stopped the car.   He turned around and saw the
    victim falling forward, and he saw the defendant holding a small
    black gun pointed at the victim's head.     There was evidence from
    which the jury could infer that Soto heard only one shot because
    he experienced ringing in his ears after the detonation.
    Video recordings from security cameras located at Essex and
    High Streets, Newton and Cabot Streets, Sam's Food store, and
    Holyoke Medical Center were admitted in evidence and shown to
    the jury.   The video recording from the Holyoke Medical Center
    showed Soto, Felipe, and Angel inside the hospital between
    12:56:47 A.M. and 12:57:42 A.M. on January 29, where they
    earlier had picked up the victim.     It also showed the Altima in
    the parking lot.
    The video recording from the security camera at Essex and
    High Streets showed the Altima stopped in the road.     A person in
    the rear passenger's side seat could be seen getting out of the
    car and running toward High Street.    That person was followed by
    a person in the front passenger's side seat, and then the
    8
    driver.   Those three people could be seen running toward High
    Street.   The next person to step out of the car was a person in
    the rear driver's side seat.   He walked around the rear of the
    car to the rear passenger's side door, opened it, and leaned
    inside for about thirteen seconds.   That person then backed away
    from the car and walked around the rear of the car toward the
    driver's side.   The person entered the car through the driver's
    door and drove away.   The video tape indicated this took place
    between about 2:02:22 A.M. and 2:02:56 A.M. on January 29, 2010.
    Soto's testimony that he, Felipe, and Angel met outside
    Sam's Food store shortly after they fled from the Altima was
    corroborated by the video recording from the security cameras
    outside and inside Sam's Food store.   The video recording from
    the front door area showed the three men as they arrived at the
    store, variously between 2:04:02 A.M. and 2:04:17 A.M. on
    January 29.   The video recording from inside the store showed
    Angel and Soto inside the store, and it later showed Angel and
    Felipe talking at the front door.    These video recordings
    corroborated Soto's testimony that he, Felipe, and Angel had
    made their way on foot to Sam's Food store.
    The video recordings from the security cameras outside the
    front and at the rear parking lot at Sam's Food store showed the
    Altima turning right onto High Street from Cabot Street and then
    approach the front door area of the store at 2:04:18 A.M.     The
    9
    front door video recording showed Angel talking on his cellular
    telephone.    Cellular telephone records of Angel and the
    defendant indicate that at this same time the defendant called
    Angel's cellular telephone, and their cellular telephones were
    connected for forty-four seconds, beginning at 2:04:07 A.M. on
    January 29.   The jury could have inferred from this evidence
    that Angel was talking to the defendant on his cellular
    telephone and told him that Soto, Felipe, and Angel were at
    Sam's Food store and that the defendant should return the Altima
    to them at that location.
    The period that elapsed from the time the Altima stopped on
    Essex Street, 2:02:22 A.M., until the Altima arrived at Sam's
    Food store where Soto, Angel, and Felipe were waiting, at
    2:04:18 A.M., was one minute and fifty-six seconds.    The
    inference that Soto, Angel, and Felipe were the three figures
    who fled from the Altima on Essex Street, and the corresponding
    inference that the defendant drove the Altima from Essex Street
    to Sam's Food store, given the brief time span involved, was
    extremely powerful.   There would only have been enough time for
    the convergence of Soto, Angel, Felipe, and the Altima at Sam's
    Food store by 2:04:18 A.M. if events had occurred as Soto and
    Felipe had testified.   The defendant drove the Altima down two
    streets of a single city block (Newton and Cabot) to Sam's Food
    10
    store, while Soto, Angel, and Felipe ran along the other two
    streets of the same city block (Essex and High) to the store.
    Although the identity of the various occupants of the car
    could not be ascertained from the Essex and High Streets video
    camera images, the video recording (in tandem with the Sam's
    Food video recording) corroborated Soto's testimony concerning
    their movement based on where they sat in the Altima.   Based on
    this evidence the jury could have found that Soto was the
    driver, that Angel was the front passenger, and that Felipe was
    the right rear passenger, all of whom fled, and that the
    defendant was the left rear passenger who walked over to the
    rear passenger's side door, opened it and leaned inside, and
    then drove the car away.
    Deoxyribonucleic acid (DNA) evidence indicated that the
    victim's DNA matched the single-source DNA profile obtained from
    a blood stain on the defendant's right boot,2 and the major-
    source DNA profile obtained from the edge of the defendant's
    right jacket pocket.3   The victim's DNA also matched the major
    2
    The probability of a deoxyribonucleic acid (DNA) profile
    match here from a randomly selected unrelated individual is
    about one in 136.8 trillion in the Caucasian population, one in
    10.27 quadrillion in the African-American population, one in
    1.036 quadrillion in the Hispanic population, and one in 1.647
    quadrillion in the Asian population.
    3
    The probability of a DNA profile match here from a
    randomly selected unrelated individual is about one in 9.881
    billion in the Caucasian population, one in 238.5 billion in the
    African-American population, one in 48.26 billion in the
    11
    profile of a blood stain on the Altima's headliner (roof
    interior).4
    In addition, transfer stains of human blood were found on
    the driver's door, the gear shift, the steering wheel, the rear
    view mirror, and the emergency brake of the Altima.   From this
    evidence the jury could infer that the defendant transferred the
    victim's blood from his hands when he closed the driver's door,
    held the steering wheel, adjusted the rear view mirror, and
    moved the gear shift into drive.   The jury also could infer that
    the defendant stepped in the victim's blood when he removed his
    body from the Altima.   Human blood stains were found on the back
    side of the fourth and fifth fingers of the right-hand glove
    recovered from the defendant.   None of these blood stains was
    tested for DNA.   The jury could have inferred that the blood was
    the victim's, which sprayed back onto only two fingers of the
    glove exposed at the time the defendant fired two shots into the
    back of the victim's head at close range.
    The defendant made a statement to police in which he denied
    knowing the victim and denied being in the Altima in the early
    Hispanic population, and one in 115.7 billion in the Asian
    population.

    The probability of a DNA match here from a randomly

    Hispanic population, and one in 1.647 quadrillion in the Asian
    population.
    12
    morning hours of January 29.   He also denied owning a gun.
    However, police recovered a gun cleaning kit from the
    defendant's apartment.
    A medical examiner testified that the victim had sustained
    three gunshot wounds to the head.   Two were on the left rear
    side, almost on top of each other; a third was on the right
    temple.    She opined that at least one of the left rear wounds
    and the right temple wound were fatal.
    Soto and Felipe heard one gunshot while inside the Altima,
    and they heard a second gunshot as they were making their way to
    Sam's Food store.   St. Amand also thought that she heard two
    shots.    A shell casing was found in the vicinity where the
    Altima stopped on Essex Street.   Although the murder weapon was
    not found, a ballistics expert opined that the gun used to kill
    the victim was a Jennings Bryco model J22 semiautomatic pistol.
    This is a .22 caliber firearm similar to the gun Soto testified
    that he saw the defendant holding after he heard the first shot.
    This type of gun is very loud and is capable of firing shots in
    rapid succession, thus explaining how two projectiles could be
    nearly on top of one another, and why Soto and Felipe
    experienced ringing in their ears, and were unable to discern
    that two shots had been fired when they were inside the car.      It
    also is consistent with a shell casing being ejected from the
    gun where it was recovered on Essex Street after the defendant
    13
    opened the right rear door of the Altima and fired one shot into
    the victim's right temple.
    The evidence, taken in the light most favorable to the
    Commonwealth, was sufficient to support a conviction of
    deliberately premeditated murder.    The defendant fired two shots
    at close range into the back of the head of the victim, which
    alone, is sufficient to support a conviction of deliberately
    premeditated murder.     See Commonwealth v. Coleman, 
    434 Mass. 165
    , 168-169 (2001).   He then went around the other side of the
    car, opened the rear passenger's side door, and fired a third
    shot into the right temple of the victim.    There was no error in
    the denial of the defendant's motion for a required finding of
    not guilty.
    3.   Speedy trial.    On September 20, 2011, the defendant
    filed a motion to dismiss, pursuant to Mass. R. Crim. P. 36 (b),
    alleging the denial of his right to a speedy trial.     The motion
    was denied on October 31, 2011, by a judge who was not the trial
    judge.   "Under rule 36, if a defendant is not 'tried within
    twelve months after the return day,' he . . . is entitled upon
    motion to a dismissal of the charges."     Commonwealth v. Denehy,
    
    466 Mass. 723
    , 729 (2014), quoting Mass. R. Crim. P. 36 (b) (1)
    (C), (D).   Because the return day in this case was March 2,
    14
    2010, the day of arraignment,5 and more than one year had passed
    before he filed his motion to dismiss under rule 36, on
    September 20, 2011, the defendant established a prima facie
    violation of the rule.   See 
    Denehy, supra
    .    The burden shifts to
    the Commonwealth to justify the delay, which it may do by
    showing that a certain portion of the delay falls within one of
    the excluded periods provided by rule 36 (b) (2), or by a
    showing that the defendant acquiesced in the delay, or that he
    benefited from the delay.   
    Id. A failure
    to object to a
    continuance or other delay constitutes acquiescence.
    Commonwealth v. Tanner, 
    417 Mass. 1
    , 3 (1994).     The filing of a
    rule 36 motion tolls the running of the time within which a
    defendant must be brought to trial.     Barry v. Commonwealth, 
    390 Mass. 285
    , 294 (1983).   For purposes of a rule 36 calculation of
    excludable periods, the docket and the clerk's log are prima
    facie evidence of the facts recorded therein.     
    Id. at 289.
      The
    period from March 2, 2010, to September 20, 2011, is 567 days.
    The Commonwealth was required to account for at least 202 days.
    The original pretrial hearing date, August 24, 2010, was
    continued to November 16, 2010, by agreement of the parties, as
    reflected in the clerk's log.     This period, eighty-four days, is
    excludable by reason of the defendant's acquiescence in the
    5
    See Mass. R. Crim. P. 2 (b) (15), as amended, 
    397 Mass. 1226
    (1986).
    15
    delay.    See Commonwealth v. Spaulding, 
    411 Mass. 503
    , 504
    (1992).
    The pretrial hearing was continued again from November 16,
    2010, to December 13, 2010; then to January 11, 2011; and then
    to February 16, 2011.    The defendant voiced no objection or
    opposition to these continuances and thus is deemed to have
    acquiesced in them, regardless whether the continuances were
    ordered by the court or the subject of an agreement of the
    parties.   See 
    Denehy, supra
    at 731.   The periods involved
    comprise ninety-two days that are excludable.
    On February 16, 2011, the defendant expressly agreed to a
    trial date of September 12, 2011, thus acquiescing in a period
    of 208 days.    This amount is excludable.
    The Commonwealth filed a motion on July 20, 2011, to
    continue the trial date.    The motion was allowed, and the trial
    was continued to October 14, over the defendant's objection.
    The defendant's original acquiescence in the setting of the
    original trial date of September 12, 2011, is unaffected by the
    continuance over his objection.    However, the time between
    September 12 and September 20, 2011, is chargeable to the
    Commonwealth.   The total amount of excludable time between
    March 2, 2010, and September 20, 2011, was 384 days, leaving 183
    days chargeable to the Commonwealth.    This was well within the
    16
    one-year requirement of rule 36.   The motion properly was
    denied.
    4.    Renewed motion to dismiss.   The defendant filed a
    renewed motion to dismiss on December 2, 2011, alleging both a
    violation of rule 36 and a claim of prosecutorial misconduct in
    the delayed production of discovery.   Circumstances that
    occurred between September 20, 2011, the date the defendant
    filed his first motion to dismiss and December 2, 2011, the date
    he filed his renewed motion are relevant to our discussion.
    The defendant's first motion to dismiss was heard on
    September 28, 2011, by a judge who was not the trial judge.      It
    was taken under advisement and denied on October 31, 2011.      In
    the meantime, the defendant filed a motion to continue the
    October 14 trial date because his rule 36 motion was under
    advisement.   The trial was continued to November 17, 2011.     On
    November 15, after the rule 36 motion was denied, the
    Commonwealth served on the defendant about 300 pages of
    additional discovery, plus four "CDs" containing the videos from
    the various security cameras.   On November 16, the defendant
    orally moved to continue the trial because time was needed to
    review the additional discovery.   A second judge, not the trial
    judge, continued the trial to December 15, 2011, and charged the
    time from November 16 to December 15 to the Commonwealth.      The
    defendant filed his renewed motion to dismiss on December 2.
    17
    The motion was denied by the second judge on December 13.    The
    defendant asserts error in the denial of his renewed motion to
    dismiss.
    We first address the rule 36 claim.    The period from
    September 20, 2011, to September 28, 2011, is a reasonable time
    in which to schedule a hearing on the rule 36 motion, and is
    excludable for that reason.    Moreover, the rule 36 clock was
    tolled by reason of the filing of the motion.   See 
    Barry, 390 Mass. at 294
    ; Mass. R. Crim. P. 36 (b) (2) (A) (v) (period
    between request for hearing and conclusion of hearing is
    excludable).   In addition, a period of not more than thirty days
    during which the motion was taken under advisement by the first
    judge is excludable.   See rule 36 (b) (2) (A) (vii).   Thus, the
    period from September 20 to October 28, or thirty-eight days, is
    excludable.    The three additional days taken by the first judge
    in deciding the first rule 36 motion are not excludable.
    The period from November 1 to November 16, 2011, is
    excludable because the defendant had moved to continue the trial
    from October 14 to November 17.   On November 16 the second judge
    continued the trial to December 15, 2011, and charged the time
    to the Commonwealth.   Thus, sixteen days are excludable from the
    period between November 1 and December 15.
    The period of time from September 20 to December 2, 2011,
    the date the renewed motion to dismiss was filed, was seventy-
    18
    three days, of which fifty-four days are excludable.      The total
    time from arraignment to December 2, 2011, was 640 days, of
    which the Commonwealth had to account for 275 days.    A total of
    438 days are excludable.   There was no violation of rule 36.
    We turn to the claim of prosecutorial misconduct.      Rule 36
    (c) provides that
    "[n]otwithstanding the fact that a defendant is not
    entitled to a dismissal under subdivision (b) of this rule,
    a defendant shall upon motion be entitled to a dismissal
    where the judge after an examination and consideration of
    all attendant circumstances determines that: (1) the
    conduct of the prosecuting attorney in bringing the
    defendant to trial has been unreasonably lacking in
    diligence and (2) this conduct on the part of the
    prosecuting attorney has resulted in prejudice to the
    defendant."
    Rule 36 (c) is consistent with constitutional principles.     See
    generally Barker v. Wingo, 
    407 U.S. 514
    (1972).
    There was evidence that the delays were caused in part by
    the laboratory assigned to perform the DNA tests, by failure of
    the police to deliver reports and witness statements to the
    district attorney in a timely manner, and by the failure of the
    district attorney's office to provide timely disclosure of
    certain cellular telephone records.   Some of this came to light
    at the July 20, 2011, hearing on the Commonwealth's motion to
    continue the September 12 trial date.   Counsel for all
    defendants were present, and at one point counsel for Soto
    stated, without objection or opposition or expression of
    disassociation from other counsel, including trial counsel for
    19
    the defendant (who is not appellate counsel), "[W]e should have
    acted sooner. . . .    But having said that, the Government also
    bears some of the brunt of the responsibility here.    And the
    laboratory as well.    So I think all of us are culpable in equal
    degrees."   The second judge rejected the claim of prosecutorial
    misconduct.   He found that the belated discovery disclosure was
    "not intentional but rather the result of oversight," and that
    the defendant had not shown prejudice.    Accordingly, the
    defendant has not shown that the second judge erred.    The
    renewed motion to dismiss properly was denied.
    5.   Mistrial.    The defendant urges us to invoke our powers
    under G. L. c. 278, § 33E, and conclude that the trial judge
    should have declared a mistrial sua sponte with respect to
    alleged jury tampering by members of the victim's family.
    Juror no. 14 approached a court officer on the seventh day
    of trial and informed him of troublesome conduct by certain
    individuals who had been in the court room.    As a result, the
    judge conducted an individual voir dire of the jury at the
    beginning of the seventh day of the trial.    The judge asked each
    juror if he or she had heard any comments from members of the
    audience, whether the juror had had any contact with members of
    the audience, and whether the juror had heard other jurors
    express any concerns about members of the audience.    Her final
    question to each juror asked whether the juror could remain fair
    20
    and impartial.   All jurors indicated that they could remain fair
    and impartial.   Three jurors heard comments or observed conduct
    from members of the audience, as summarized below.
    While waiting for an elevator juror no. 3 heard a young,
    brown-haired woman (later identified as the defendant's aunt)
    who had been in the audience say to a group of people with whom
    she was talking, "If they send him upstate, he'll be dead."
    Juror no. 3 indicated that this did not affect his ability to
    remain fair and impartial.
    While walking down a corridor in the court house, juror no.
    14 heard a woman who had been a member of the audience say to a
    group of nonjurors, "Every one of those fucking jurors . . . ,"
    and then abruptly stop speaking when she saw juror no. 14
    approaching.   Juror no. 14 saw this same woman (later identified
    as the same aunt) look at a group of jurors in the parking lot,
    and then spit on the ground.   Juror no. 14 found this person's
    conduct "atrocious" and "vulgar," but the juror assured the
    judge that she could remain "fair and impartial."    Juror no. 14
    spoke to other jurors.   She and other jurors speculated whether
    their license plates could be used to locate them, but this
    speculation was not based on anything that a member of the
    audience said or did.    She expressed concerns that at the end of
    each day jurors and spectators left the court house at the same
    time.
    21
    Juror no. 16 was in an elevator with a group of people when
    one woman who had not been in the audience asked, "What's going
    on with the trial?"   A blonde-haired woman who had been in the
    audience (later identified as the defendant's mother) said,
    "None of her fucking business what's going on with the trial."
    Juror no. 16 was not affected by the incident.
    The judge asked the prosecutor to identify the women
    described by jurors nos. 3, 14, and 16.    The blonde-haired woman
    was identified as the victim's mother; the woman referenced by
    jurors nos. 3 and 14 was identified as an aunt of the victim.
    The judge excluded them from the court room for the balance of
    the trial.   The judge characterized the conduct of the victim's
    aunt as "potential juror tampering" and said she would refer the
    matter to the Attorney General.
    The prosecutor requested that juror no. 14 be excused.     The
    defendant objected, and the judge denied the prosecutor's
    request.   The judge determined that based on the voir dire,
    juror no. 14 remained "fair and impartial."
    "If, during trial or jury deliberations, the judge is
    advised of a claim of an extraneous influence on the jury, he or
    she is to first 'determine whether the material . . . raises a
    serious question of possible prejudice.'    Commonwealth v.
    Jackson, 
    376 Mass. 790
    , 800 (1978).   If 'a juror indicates
    exposure to the extraneous material in question, an individual
    22
    voir dire is required to determine the extent of that exposure
    and its prejudicial effect.'    Commonwealth v. Tennison, 
    440 Mass. 553
    , 557 (2003).    Because the judge 'is in the best
    position to observe and assess the demeanor of the juror[s] on
    voir dire . . . [t]he determination that [a] juror was
    unaffected by extraneous information is within the sound
    discretion of the trial judge.'     (Citation omitted.)   
    Id. at 560."
       Commonwealth v. Meas, 
    467 Mass. 434
    , 451 (2014), cert.
    denied, U.S. Supreme Ct., No. 13-10630 (Oct. 6, 2014).      Here,
    the judge followed the correct procedure and was entitled to
    rely on the jurors' assertions of impartiality, and on her
    observations of them during voir dire in assessing whether they
    could remain fair and impartial.     We also are mindful that
    experienced trial counsel voiced no objection.     The defendant
    has failed to demonstrate any "solid evidence of a distinct
    bias," Commonwealth v. Bryant, 
    447 Mass. 494
    , 500 (2006),
    quoting Commonwealth v. Leahy, 
    445 Mass. 481
    , 499 (2005), or
    that the judge otherwise abused her discretion.     There was no
    error.
    6.    The Ciampa instruction.    The defendant contends that
    the judge's instruction concerning the manner in which the jury
    should consider the testimony of a cooperating witness was
    error.    In particular, he argues that the judge did not
    "adequately focus the jury's attention on the incentives that
    23
    could have influenced [Soto's and Felipe's] testimony."     
    Ciampa, 406 Mass. at 263-264
    .   In addition, he argues, the judge failed
    to instruct the jury that "the government did not know whether
    [Soto and Felipe] were telling the truth]."   
    Id. at 264.
        See
    Commonwealth v. Meuse, 
    423 Mass. 831
    , 832 (1996).   There was no
    objection to the jury instruction.   We review to determine if
    there was error, and, if so, whether it created a substantial
    likelihood of a miscarriage of justice.   Commonwealth v. Wright,
    
    411 Mass. 678
    , 682 (1992), S.C., 
    469 Mass. 447
    (2014).
    Trial counsel began his cross-examination of both Soto and
    Felipe with a discussion of the unredacted terms of their
    cooperation agreements and the nolle prosse filed in the murder
    case against each witness.   Both Soto and Felipe still had
    outstanding indictments for accessory after the fact of murder.
    He elicited from both witnesses that they had spent twenty-one
    months in custody in lieu of bail, that conditions of their
    incarceration were stressful, and that the Commonwealth was
    "totally in charge" of whether their testimony was in breach of
    their cooperation agreements.   The decision to cooperate with
    the Commonwealth was not difficult for either man, even though
    for Felipe it meant he might have to testify against his brother
    Angel.   Trial counsel also stressed the fact that prior to their
    being held, police interrogators repeatedly told them they did
    not believe their early statements, implying that the
    24
    Commonwealth was looking for specific testimony and until it was
    forthcoming they would remain in jail.
    Toward the end of his closing argument trial counsel
    forcefully argued that Soto and Felipe had made what were
    essentially the deals of a lifetime.   He argued that the case
    came down to whether the jury believed Soto and Felipe.    He
    mocked the cooperation agreements, claiming,
    "the Commonwealth controls what [I] would argue to you is a
    puppet. [The Commonwealth] control[s] the strings . . . .
    The agreement that they signed to get out of jail . . .
    says, all the rights are with the government to determine
    what we really think about your testimony. . . . Read it
    in detail. Did [they] have any choice? Did either one of
    them have any choice? They were walking away from murder
    in the first degree, they were walking out of jail after 21
    months. . . . I think I recorded that [they] said I'm just
    here to tell the truth. I think I recorded that [they]
    said I'm just here to tell the truth 32 times. I guess
    that's for you ladies and gentlemen of the jury to decide
    whether or not [they were] there to tell the truth, or to
    fulfill the obligations of [their] cooperation agreement. .
    . . Well, the cooperating individuals are cooperating for
    only one reason. They're cooperating because they're
    afraid that they'll go back to being charged with murder in
    the first degree." (Emphasis added.)
    The prosecutor never mentioned the cooperation agreements
    in his closing argument.   His argument carefully and
    methodically focused upon the importance of the security camera
    video recordings and the forensic evidence, and how they
    corroborated the testimony of Soto and Felipe.   His argument
    rested on painstaking attention to detail.   He never suggested
    that the Commonwealth had superior knowledge that the witnesses
    25
    were telling the truth; rather, he stated that it was the jury's
    function to determine the truth.
    The trial judge focused upon the fact that trial counsel
    wanted to offer the cooperation agreements with nothing
    redacted.   Counsel made it clear that he wanted nothing
    redacted.   After Soto's cooperation agreement was admitted in
    evidence the judge instructed the jury, "[N]o matter what
    agreement[s] exist or do not exist between the Commonwealth and
    any witness in the case, you are the only ones who determine[]
    the truth in the case.   Period.   You are the only ones, no one
    else, who determine the truth and the facts in the case
    consistent with the burden of proof and presumption of innocence
    as discussed before."    After Felipe's cooperation agreement was
    admitted in evidence the judge instructed the jury, "I told you
    this yesterday when we had the same issue with another witness,
    Mr. Soto.   The instruction remains the same, but now with
    respect to this witness.   Any reference in any agreement to an
    agreement being based on a person telling the truth, I
    underscore to you the Commonwealth does not determine what the
    truth is.   The jury determines what the truth is, based on the
    evidence that they determine to be credible."
    In her final general instructions, the judge told the jury
    that when assessing a witness's credibility they could consider
    whether the witness has an interest in the outcome of the case,
    26
    any motive or reason they may have in testifying, and the
    witness's appearance and demeanor.    She later instructed the
    jury that with respect to the testimony of Soto and Felipe, who
    were alleged accomplices, they must bring "heightened scrutiny
    and care in evaluating and analyzing the testimony of those
    witnesses."   She further instructed, if a witness "has a
    cooperation agreement with the Commonwealth . . . you must
    scrutinize that witness's testimony with that high, high degree
    of scrutiny. . . .   [W]ith respect to those so-called
    cooperation agreements, I remind you that promises to tell the
    truth within cooperation agreements are irrelevant.    The jury
    determines what the truth of the matter is in the case, no one
    else."
    In Ciampa, we pointed to specific deficiencies in the
    judge's instructions.   We said that language in a cooperation
    agreement to the effect that the agreement was "contingent upon
    the truthfulness of [the cooperating witness]" should be
    redacted "on request" by a defendant (emphasis added).      
    Ciampa, 406 Mass. at 262
    .    See Mass. G. Evid. § 1104(c) (2014).   Here,
    not only was there no request for such redaction, but also trial
    counsel specifically indicated he did not want anything
    redacted.   This language went to the heart of the defense.
    Trial counsel wanted the jury to understand that the
    Commonwealth brought tremendous pressure to bear on Soto and
    27
    Felipe until they came forward with a story that the
    Commonwealth wanted them to tell -- and that truth played no
    part in it.
    We also said in Ciampa that a judge should warn the jury
    that "the government did not know whether [the cooperating
    witness] was telling the 
    truth." 406 Mass. at 264
    .   However,
    failure to so instruct, standing alone, is not reversible error.
    See 
    Meuse, 423 Mass. at 832
    .     It is only where the prosecutor
    has vouched for the witness or suggested having special
    knowledge by which he or she can verify the witness's testimony
    that such an instruction must be given to avert reversible
    error.   See id.; 
    Ciampa, 406 Mass. at 266
    .    Here, the prosecutor
    never vouched for Soto or Felipe.     Nor did he suggest that he
    had special knowledge by which to determine that they were
    telling the truth.     There was no error in the failure to give
    such an instruction.
    Finally, in Ciampa we said that a judge should "focus the
    jury's attention on the particular care they must give in
    evaluating testimony given pursuant to a plea agreement that is
    contingent on the witness's telling the 
    truth." 406 Mass. at 266
    .   We also said that "[w]e do not prescribe particular words
    that a judge should use" in this regard.      
    Id. The judge
    did
    what minimally was required under Ciampa given the circumstances
    presented at the defendant's trial.     See Mass. G. Evid.
    28
    § 1104(f) (2014).    She also reinforced the importance of such
    inquiry by instructing the jury that they should scrutinize the
    testimony of Soto and Felipe with great care by virtue of their
    being alleged accomplices, something we encourage but do not
    require.    See Commonwealth v. Thomas, 
    439 Mass. 362
    , 372 (2003).
    There was no error.
    7.     Review under G. L. c. 278, § 33E.   We have reviewed the
    transcripts, the briefs, and the entire record, and we discern
    no reason to exercise our power under G. L. c. 278, § 33E, to
    reduce the conviction of murder to a lesser degree of guilt or
    order a new trial.    The manner in which this case was
    prosecuted, defended, and judged was exemplary.    In the final
    analysis, this case is a testament to the power of
    circumstantial evidence.
    Judgments affirmed.
