    A pretrial motion to suppress evidence was heard by E.
    Susan Garsh, J., and the case was tried before Robert J. Kane,
    J.
    Jeanne M. Kempthorne for the defendant.
    Mary O'Neil, Assistant District Attorney, for the
    Commonwealth.
    HINES, J.     On November 3, 2009, Chad Fleming (victim) was
    killed during a robbery (or attempted robbery) of drugs that he
    2
    had planned to sell to the defendant, Nelson Melo.    The
    defendant and Aaron Morin were charged with murder in the first
    degree in the death of the victim.    The Commonwealth contended
    that the defendant acted as a joint venturer with Morin, who was
    tried separately.    In November, 2012, a jury convicted the
    defendant of murder in the first degree on the theory of felony-
    murder.1,2   Represented by new counsel on appeal, the defendant
    argues (1) error in the partial denial of his motion to suppress
    statements he made to police; (2) error in the denial of defense
    counsel's motion to withdraw from the case two days before
    trial; and (3) ineffective assistance of trial counsel.     We
    conclude that the defendant's motion to suppress statements made
    after being taken involuntarily to the police station should
    have been allowed in its entirety because these statements were
    the inadmissible fruits of an unlawful arrest.    Because the
    defendant did not seek suppression on this ground, however, we
    review to determine if the error created a substantial
    likelihood of a miscarriage of justice, and conclude that it did
    1
    The jury did not indicate the predicate felony on which
    the verdict was based. The possible predicate felonies were
    armed or unarmed robbery, or the attempt to commit armed or
    unarmed robbery.
    2
    The Commonwealth argued also that the murder was
    deliberately premeditated and committed with extreme atrocity or
    cruelty, but the jury did not find the defendant guilty under
    these theories.
    3
    not.       We reject as well the other claims of error and,
    therefore, affirm the order denying defense counsel's motion to
    withdraw and affirm the defendant's conviction.
    Background.     We recite the facts the jury could have found.
    The victim, who was twenty-five years of age, lived in Florida
    and regularly supplied the defendant with Percocet for the
    defendant's drug dealing business.       On November 3, 2009, the
    victim flew to Providence, Rhode Island, rented an automobile,
    and drove to Massachusetts to meet with the defendant to supply
    him with Percocet.      He telephoned his girl friend to let her
    know that he had safely landed.      She never heard from him again.
    The defendant and his wife3 were both involved in the sale
    of Percocet and both developed a dependency on the drug.      The
    defendant supplied pills to his friend Morin, and also to
    Michael Stenstream4 and Stenstream's friend Brandon George.5
    About one week prior to the murder on November 3, the
    defendant's wife and George drove to Florida to purchase pills
    from the victim.      The defendant's wife gave the victim $42,000
    in cash.      The victim telephoned the defendant because the amount

    4
    was short of what he had expected.   Nevertheless, the victim
    supplied the defendant's wife with about 4,000 Percocet pills
    that she brought home to the defendant.
    Before this trip to Florida, Morin told the defendant that
    the victim was dealing to other people in Massachusetts.     The
    defendant expressed disbelief, so Morin, in the defendant's
    presence, telephoned a man and put him on speakerphone.     The man
    confirmed what Morin had stated.
    On the morning of November 2, the day before the murder,
    Morin visited the defendant at the defendant's wife's home,
    where they were then living.   The defendant's wife had been
    sleeping.    She woke up and heard Morin whisper something about
    "hitting" someone and something about a black hat.   She also
    overheard Morin say, "I'll take care of the other two" or "They
    will take care of the other two."
    During the late afternoon of November 2, Morin met with his
    friend Michael Matteson.    Matteson owed Morin money, and Morin
    offered him an opportunity to repay the debt.   Morin told
    Matteson that he was going "to rob his connect's connect and
    make some money."   Morin's "connect," or drug supplier, was the
    defendant.   Morin explained that the defendant's "connect" would
    be arriving to sell Percocet and they were going to rob him;
    "they" included Morin, a person named Walter Babcock, and the
    defendant.   Morin explained further that the defendant's
    5
    "connect" would be at an apartment owned by the defendant,6 and
    Morin would receive a telephone call when he arrived.    The
    "robbers" would go through the back door, Matteson would take
    the money and drugs, Babcock would grab the defendant's
    "connect," and Morin would make it look like he was holding down
    the defendant.   Matteson said he would think about it, but
    ultimately decided not to participate.
    On November 3, the defendant and his wife expected the
    victim to visit them at their apartment.   The defendant had his
    wife help package between $42,000 and $58,000 in cash.     The
    defendant's wife heard him ask someone over the telephone
    whether he was "going to get it back."   Shortly after 8 P.M.,
    the defendant left the apartment wearing a black hat.7    He took
    the money with him.   Approximately thirty minutes later, the
    defendant's wife was speaking with the defendant on the house
    telephone when the victim telephoned her on her cellular
    telephone.   After communicating with her husband, the
    6
    The defendant became a part owner of his parents' two-
    family home on Bay Street in Taunton. The defendant's sister,
    Lucia Rodriguez, and her husband, Gabriel Rodriguez, lived in
    the first-floor apartment of the home. The defendant, in
    October, 2009, rented the second-floor apartment to Stenstream.
    7
    Stenstream had seen the defendant earlier outside his
    (Stenstream's) apartment, between 6:30 and 7 P.M. Stenstream
    told the defendant that he had dinner plans later with his girl
    friend. The defendant remarked, "You should go out to dinner."
    Stenstream and his girl friend left for dinner sometime between
    8:30 and 8:45 P.M.
    6
    defendant's wife told the victim that the defendant wanted him
    to go to Stenstream's apartment.   See note 
    6, supra
    .
    At the Bay Street residence, the defendant's sister, Lucia
    Rodriguez, and her husband, Gabriel Rodriguez,8 were in the
    living room of the first-floor apartment.    See note 
    6, supra
    .
    After Gabriel had settled in to watch a television program that
    commenced at 9 P.M., the defendant came into the apartment and
    spoke with Lucia.    The defendant told her that he was going
    upstairs to speak with the victim.
    Soon thereafter Lucia heard the footsteps of multiple
    people heading upstairs.    Gabriel heard more than one set of
    footsteps coming from above.    The defendant came down from the
    second-floor apartment and went into the kitchen with Lucia.      He
    told her to stay downstairs then "bolted" back upstairs.     While
    the defendant was speaking to her, Lucia heard a "big rumbling."
    Gabriel then heard what sounded like multiple people
    running down the back stairs of the second-floor apartment.
    Looking outside a window, he saw an automobile leave his home
    quickly.   Lucia heard people run out and saw a gray automobile
    departing with two people in the front and one person in the
    back.    She heard the voice of another person that she did not
    recognize upstairs with her brother.
    8
    Because the defendant's sister and her husband share the
    same last name, we shall refer to them by their first names.
    7
    The defendant came downstairs, took some ice packs from the
    refrigerator, told Lucia he would be "right back," and returned
    upstairs.    After a few minutes the defendant asked Lucia to
    check on the victim because he was not responding.    From the
    kitchen, Gabriel heard something about a fight and heard the
    defendant say, "I think he got hurt."
    Upstairs, Lucia discovered the victim lying on his back on
    a bed in the spare bedroom.   There were ice packs on his neck.
    She tried to see whether he was breathing.    The victim was not
    moving, and she told the defendant to telephone 911.    The
    defendant insisted that he wanted his wife.
    At about 8:45 or 9 P.M., Morin, out of breath, telephoned
    the defendant's wife, asking for the defendant.    Morin asked
    her, "Do you know what happened?"   He added, "Man, that kid was
    tough."   The defendant's wife told Morin that the defendant was
    not there.   The defendant's wife asked, "What's going on?" and
    Morin replied, "I've got to call [Lucia]."    The defendant's wife
    then telephoned Lucia, who stated that she did not know where
    the defendant was.   Soon thereafter Lucia arrived and insisted
    that the defendant's wife and their daughter accompany Lucia
    back to the Bay Street apartment.    The defendant's wife agreed.
    Stenstream and his girl friend returned to his apartment at
    approximately 9:45 P.M.    He sent a text message to the defendant
    to confirm whether the defendant was still there.    The defendant
    8
    did not respond.    There was an unfamiliar automobile in the
    driveway (the victim's rental vehicle).       Stenstream's girl
    friend waited in his automobile.    He then went up to his
    apartment and shortly thereafter returned to the automobile.
    Stenstream brought his girl friend upstairs to his apartment and
    instructed her to go straight to his bedroom, to keep her head
    down, and not to look around.    As she made her way through the
    apartment, she observed blood on the floor and on the couch.
    Stenstream found the defendant and the victim in a spare
    bedroom.    The victim was lying on his back, his eyes and mouth
    were open, and he was not moving.    The defendant was holding a
    package of peas or ice to the victim's head and was telling the
    victim to "wake up."    Stenstream asked what was going on.       The
    defendant replied, "Don't worry about it.      Close the door."
    Stenstream left, but returned shortly thereafter suggesting that
    the defendant telephone an ambulance.9    Stenstream asked again
    what was going on.    The defendant said, "Fucking Ace."10
    Stenstream again asked the defendant to arrange for an
    9
    Stenstream noticed blood on the sofa and carpet in the
    living room. He also picked up some zip ties on the living room
    floor, one of which appeared to have blood on it, and threw them
    in the garbage. He disposed of some clothing in a dumpster
    outside. He attempted to use "cleaning solution" to clean the
    apartment.

    9
    ambulance.   The defendant said, "I'll take care of it.     We
    should get him to the hospital."
    The defendant lifted the victim and started carrying him
    down the stairs.   The defendant was struggling and asked
    Stenstream for help.   Stenstream was reluctant, but agreed.
    Gabriel came out of his apartment.   He could not find a pulse
    and noted that the victim was not moving.    Stenstream observed
    that the victim's chest was blue and his legs were stiff.
    Gabriel opened the door to the back seat of the victim's rental
    vehicle, and the defendant and Stenstream put the victim inside.
    The defendant went to Lucia's apartment, where he spoke
    with his wife, who by then had arrived.   After inquiring about
    the victim, the defendant's wife went out to the victim's rented
    automobile where she saw him in the back seat.    She observed
    that the victim's eyes were open and he was not moving; his
    wrist was by his forehead in a fixed position.    She started
    crying and screaming, and yelled at the defendant, "He's dead!"
    The defendant drove off with the victim.11
    The defendant's wife went inside Stenstream's apartment,
    and he gave her the victim's jacket, shoes, and wallet.     She saw
    blood "everywhere" in the living room, including on the walls
    11
    Stenstream testified that after they moved the victim to
    the automobile, the defendant waited twenty to twenty-five
    minutes before leaving.
    10
    and on the floor.   After about five to ten minutes, she went to
    Morton Hospital in Taunton, where the defendant had taken the
    victim.
    While in the entrance area to the emergency room, the
    defendant attempted to perform chest compressions on the victim.
    Medical personnel took over and brought the victim into an
    examination room.   It became immediately clear to the staff that
    the victim was in a state of rigor mortis and was dead.     A
    physician pronounced the victim dead at 11:05 P.M.   The
    physician then spoke with the defendant, who provided the
    victim's name and stated that he was his friend from Florida.
    The defendant also told the doctor that the victim had gone out
    for a cigarette and that, when he did not return about fifteen
    minutes later, the defendant went to check on him, finding him
    outside on the ground.   In response to questions posed by the
    doctor, the defendant stated that he did not think that the
    victim had ingested any drugs.   The defendant was visibly upset.
    Police arrived shortly thereafter and, after speaking with
    the emergency room physician, talked with the defendant in the
    family room.12   In summary, the defendant gave two different
    accounts of how the victim came to be injured.   In his original
    12
    The details of the defendant's statements to police at
    the hospital and subsequently at the police station are set
    forth later in this opinion in the discussion of the motion to
    suppress.
    11
    version of events, the defendant stated that the victim had
    taken a handful of pills and then went outside to make some
    telephone calls.    The defendant stated that, when the victim had
    not returned thirty minutes later, he went to check on the
    victim and found him outside, lying on the ground and bleeding
    from the head.   The defendant carried the victim upstairs; tried
    to revive him with ice cubes; and when that did not work,
    decided about ninety minutes later to bring him to the hospital.
    In the subsequent version of events, the defendant stated that
    he and the victim were visiting in Stenstream's apartment when
    three males arrived to make a drug deal.    The men pulled out
    guns.   The defendant escaped downstairs.   After the men left,
    the defendant returned upstairs and found the victim with zip
    ties around his legs.   The victim was alive and stated that he
    did not want to go to the hospital, but the defendant brought
    him anyway.
    Police transported the defendant from the hospital to the
    police station, where he was interviewed after being given
    Miranda warnings.   In keeping with the motion judge's ruling on
    the defendant's motion to suppress, a redacted version of the
    recorded interview was admitted in evidence and played for the
    jury.   During that portion of the interview, the defendant did
    12
    not admit to killing the victim himself or to being involved in
    the killing, or robbing (or attempting to rob) the victim.13
    The medical examiner who conducted the victim's autopsy
    opined that he died as a result of asphyxia by strangulation.
    She testified that he suffered multiple blunt force injuries to
    his head, neck, and extremities.   He had a gaping laceration to
    his scalp hidden in his hairline and rib fractures that
    perforated his lungs.   Toxicology screen results revealed that
    the victim did not have any drugs or alcohol in his system.
    On November 4, the defendant's wife went to Morin's home.
    Morin told her that he owed the defendant money and gave her
    $5,000.   Morin also said he had done a lot for the defendant.
    On November 5, Morin asked Matteson to meet him.    Morin told him
    that he should say "nothing to anybody."
    After speaking to the defendant, the police secured
    Stenstream's apartment, where they recovered zip ties from the
    kitchen trash and various items in a dumpster in the rear of the
    building.   They took samples of various red-brown stains from
    within the apartment, including in the living room and back
    stairwell, which tested positive for human blood.
    13
    The defendant did admit that there was a "drug
    transaction" going on in Stenstream's apartment and that the
    victim had given the defendant $1,000 for "using the spot." He
    stated that the victim was alive, talking and mumbling, after
    the three men had departed.
    13
    Deoxyribonucleic acid (DNA) testing revealed that the victim's
    DNA was present on one of the zip ties recovered.   Further,
    testing showed that the victim's DNA was recovered from a stain
    on the defendant's shirt and a stain on the upper right arm of
    the defendant.14
    Telephone records admitted in evidence at trial established
    that, on the afternoon of November 3, the telephones of the
    defendant and the victim were in communication with each other.
    In addition, between noon and midnight on that day, there were
    thirty-six contacts between the telephones of the defendant and
    Morin, including several calls made between 8:45 and 11:30 P.M.
    The defendant did not testify.   His trial counsel argued
    that the Commonwealth's witnesses were not to be believed for
    various reasons, including the fact that most had entered into
    agreements with the Commonwealth providing for their immunity.
    Defense counsel also argued that the defendant's statements were
    not voluntarily made and that the police investigation had been
    inadequate.   Defense counsel argued that the defendant had not
    been involved and did not share Morin's intent to rob or to kill
    the victim.
    14
    The statistical significance of the deoxyribonucleic acid
    (DNA) testing was presented to the jury. See Commonwealth v.
    Ortiz, 
    463 Mass. 402
    , 408 & n.10 (2012); Commonwealth v.
    Lanigan, 
    419 Mass. 15
    , 20 (1994).
    14
    Discussion.   1.   Motion to suppress statements.   a.
    Background.   The defendant filed a motion to suppress statements
    he made on November 3 and 4 at the hospital and at the police
    station, claiming, on State and Federal constitutional grounds,
    that his statements should be suppressed because they were not
    preceded by an adequate recitation of the Miranda warnings.      He
    also argued that he did not make a knowing, intelligent, and
    voluntary waiver of the Miranda rights and that his statements
    were not voluntary because of his state of exhaustion, drug
    ingestion, and drug withdrawal.   Last, the defendant asserted
    that police failed to honor his invocation of his right to
    counsel.   After an evidentiary hearing, the motion judge, who
    was not the trial judge, made the following relevant findings of
    fact, which we supplement where necessary with evidence in the
    record that is uncontroverted and that was implicitly credited
    by the motion judge, see Commonwealth v. Isaiah I., 
    448 Mass. 334
    , 337 (2007), S.C., 450 Mass 818 (2008), and with the video
    recording of the interview of the defendant, which was admitted
    in evidence at the motion hearing.15
    15
    When a defendant's interview is video recorded, we are
    "in the same position as the motion judge in viewing the
    videotape," Commonwealth v. Hoyt, 
    461 Mass. 143
    , 148-149 (2011),
    quoting Commonwealth v. Prater, 
    420 Mass. 569
    , 578 n.7 (1995),
    to determine what occurred therein and therefore independently
    make that determination. We have reviewed the video recording
    that forms the basis of this appeal.
    15
    In the late evening of November 3, 2009, Dr. Peter Bosco,
    an emergency room physician at Morton Hospital, encountered the
    defendant and the victim, who was slumped over in a wheelchair.
    The defendant was attempting to perform chest compressions on
    the victim.   The defendant told Dr. Bosco that he had been at
    the same residence with the victim; that the victim went outside
    to smoke; and that, when the victim had not returned after
    fifteen minutes, the defendant went to check on him, finding him
    there.   The defendant did not tell the doctor that he had
    brought the victim upstairs after finding him.    The defendant
    was agitated and upset, which the doctor construed as
    appropriate for someone who cared about another.
    After examining the victim, Dr. Bosco spoke with the
    defendant in the family room.    He informed the defendant that
    his friend was dead and that something did not "add up" because
    rigor mortis already had set in, suggesting that the victim had
    been dead for several hours.    The defendant appeared to be in
    disbelief; he was distraught and upset.    His speech was clear,
    but he was agitated.   As the defendant spoke with Dr. Bosco, he
    recovered his composure and pleaded with the doctor to do
    something to resuscitate the victim.    Dr. Bosco brought the
    defendant into the examination room to see the victim.    Around
    this time, shortly after 11 P.M., Taunton police Officer Ralph
    Schlageter and Detective Robert Schwartz separately arrived in
    16
    uniform at the examination room in response to a dispatch of a
    report that someone had brought a deceased person to the
    hospital's emergency room.
    Dr. Bosco escorted the defendant to the family room.       He
    explained to the defendant that, because the victim's death was
    suspicious, it would need to be investigated by the police and a
    medical examiner would take over custody of the body.    He asked
    the defendant to stay so police could speak with him.    The
    defendant was agreeable.   No police officers were in the family
    room at this time.   Dr. Bosco had not been asked by police to
    speak to the defendant.
    Dr. Bosco left the family room and informed Schlageter that
    the victim had a head wound and was in state of rigor mortis
    when he arrived, and that the defendant was the person who had
    brought the victim to the hospital.    Dr. Bosco did not suspect
    the defendant of any involvement in the death and did not
    communicate any such suspicion to Schlageter or to any other
    officer.
    Schlageter then spoke with the defendant in the family
    room.   No one else was present.   The defendant was disheveled
    and visibly upset.   He was crying, was almost hysterical, and
    put his head in his hands.   When Schlageter spoke with the
    defendant, Schlageter viewed him as a concerned friend, not as
    someone who had been involved in the victim's death.    The
    17
    defendant did not appear to have been drinking, but seemed to be
    "on something."
    After a couple of minutes, the defendant calmed down so
    that Schlageter could understand him.    They spoke for
    approximately five minutes.    The defendant was coherent and
    clear.   He identified himself and provided his date of birth as
    well as the victim's full name.     The defendant gave Schlageter
    the following account.    Around 9:30 P.M., the victim had visited
    the defendant in Stenstream's apartment.    Sometime later, the
    victim announced that he wanted to go outside to smoke and to
    make telephone calls.    About twenty to thirty minutes later, the
    defendant went downstairs to check on the victim and found him
    on the ground beaten up.    The defendant carried the victim
    upstairs back to the apartment.    Because the defendant knew that
    the victim had a history of drug use, the defendant thought that
    he may be overdosing, so he laid him on a bed and tried to
    revive him with ice.    The defendant became concerned when he saw
    the victim's skin turn blue.    Schlageter did not question the
    defendant further.     Schlageter left the room, leaving the
    defendant alone inside.     Schlageter did not give any Miranda
    warnings to the defendant before or during their conversation.
    Taunton police Detectives Susan Dykas and Shawn Mulhern
    arrived at the hospital.    They were not in uniform.     They viewed
    the victim, observing the large cut on his head, and learned
    18
    that he had been dead for a significant period of time.
    Schlageter informed the detectives that the defendant had
    brought the victim's dead body to the hospital and was in the
    family room.    Schlageter also told the detectives the substance
    of his conversation with the defendant.
    The detectives entered the family room, where they found
    the defendant alone and crying.   The detectives did not give any
    Miranda warnings to the defendant before speaking with him, or
    at any time while they spoke with him at the hospital.
    Mulhern recognized the defendant from the defendant's
    previous employment as a bouncer at a nightclub and asked what
    was going on.    The defendant gave the following account of what
    had occurred earlier that day.    The defendant had been
    "chilling" at a second-floor apartment with the victim, who was
    a friend visiting from Florida.   The victim went downstairs to
    make a telephone call, and when he did not return, the defendant
    went downstairs and found him unconscious and bleeding from the
    head.   The defendant dragged the victim back upstairs and tried
    to revive him with ice packs.    The defendant took the victim to
    the hospital when he was not doing well.
    Mulhern was the primary questioner and expressed disbelief
    that the defendant had dragged the victim upstairs.   The
    defendant then gave a different account of what had occurred.
    In this version, the defendant stated that the victim came from
    19
    Florida to use the apartment for a drug deal.   Two white males
    and one black male entered the apartment and argued with the
    victim and brandished guns, at which point the defendant went
    downstairs to his sister's apartment.   When the commotion was
    over, the defendant returned upstairs, where he discovered that
    the victim had been beaten up, his legs bound with zip ties, and
    his mouth gagged.   The victim initially was conscious, but when
    he lost consciousness, the defendant carried him downstairs with
    the help of the defendant's sister and brother-in-law, and drove
    him to the hospital.   The defendant did not make any statements
    that suggested in any way that he was responsible for the
    victim's death.
    The detectives were aware of the defendant's and the
    victim's prior involvement with drugs, and suspected that the
    defendant had more information, but not that he was responsible
    for causing the victim's death.   With the defendant's
    permission, they searched his cellular telephone and noticed
    numerous calls to a single number (Morin's).
    The detectives spent thirty to forty minutes with the
    defendant in the family room.   During this time, he squirmed
    quite a bit and appeared visibly nervous and upset.   He
    alternated between calmness and lucidity, and incoherency.      The
    defendant's eyes were somewhat bloodshot, and he appeared to be
    under the influence of drugs.
    20
    After they finished speaking with the defendant, Mulhern
    told the defendant, "We're going to go back to [the] police
    station and finish this interview because we have to sort
    through this."    Mulhern directed Schlageter to drive the
    defendant to the police station.    Schlageter escorted the
    defendant to the back seat of a marked police cruiser, which
    locked and could not be opened from the inside.   He did not
    handcuff the defendant.   He did not give Miranda warnings prior
    to or during the transport to the station, he did not ask the
    defendant any questions on the way there, and the defendant did
    not make any statements along the way or on his arrival at the
    police station.
    On arrival, at about 12:45 A.M., Schlageter brought the
    defendant into the station through the front lobby and to an
    interview room.    There, Mulhern and State police Trooper Anthony
    Spencer spoke with him.   The interview was audio and video
    recorded, and the defendant was aware that the interview was
    being recorded.    The interview lasted about two hours and forty-
    five minutes, excluding a one-hour break after two and one-half
    hours into the interview.
    At the beginning of the interview Mulhern read the
    defendant the Miranda warnings from a preprinted form.   The
    defendant nodded that he understood.   After, at 12:55 A.M., the
    defendant signed a waiver of rights from a notification of
    21
    rights form, which he did not read.   Under the signature line on
    the form, the form stated:    "Person in Custody."
    After signing the form, the following exchange between the
    defendant and Mulhern occurred.
    Defendant:       "I would feel more comfortable if I had a
    lawyer right now talking, but if you want to
    show me pictures and names, I'll give it to
    you. Because, honestly, like obviously I do
    not want to get more in a jam than this. I
    will show you who did it and everything. I
    just want out."
    Mulhern:         "Okay. So, why do you -- you feel like you
    want to -- if you don't want to talk, that's
    your right --"
    Defendant:       "The thing is I don't know."
    Mulhern:         "-- but if you feel like you need a lawyer,
    you know --"
    Defendant:       "I don't know what to do. Like, honestly,
    I'll help you but it seems like what do I
    say."
    Mulhern:         "Okay.   Why don't we ask you questions --"
    Defendant:       "Alright."
    Mulhern:         "-- and we can go from there.   We can find
    out the story first."
    Defendant:       "Alright."
    For the first hour of the interview, the defendant did not
    appear to be particularly tired, but he was experiencing some
    pain in his groin.   He told the officers that he had stopped
    dealing drugs and went "cold turkey" two or three months earlier
    because his marriage and job were being affected.    He admitted
    22
    that if he could "make a quick buck here and there," he would
    sell drugs, but that he did not "touch anything."
    After about one hour of questioning, the defendant appeared
    nervous and jumpy.    As Mulhern began to convey a high degree of
    skepticism of the defendant's statements, the defendant
    increasingly slouched.   The defendant remained alert and
    consistently resisted suggestions from the officers and
    confrontational harangues from Mulhern.   He insisted that he was
    not part of the drug deal and that he did not personally
    struggle with the victim.
    Around this time, the tenor of the interview changed.
    Mulhern frequently interrupted the defendant and, for a period
    of about twenty minutes, screamed at him in an accusatory tone.
    The defendant hung his head, but did not buckle.    At this point,
    now about ninety minutes into the interview, the defendant
    appeared to be tired and started answering some questions with
    his head down.   He adamantly insisted that he did not push or
    "tussle" with the victim or put his hands on him accidentally or
    during an argument.   The defendant was not easily led by the
    officers and spontaneously clarified several matters.
    At one point the officers left the defendant alone for
    several minutes, during which time he sniffled and his legs were
    shaking.   The defendant rubbed his eyes and looked exhausted.
    When the officers returned, the defendant continued to give
    23
    coherent, exculpatory responses although visibly tired.    For
    example, when confronted with the fact that bedding (from the
    apartment) had been stripped and left in a dumpster, the
    defendant denied having done that.    He stated that he had not
    touched the bedding and that cameras at the location would show
    that he "didn't do shit."    He also did not let himself be
    trapped by Mulhern's mischaracterizations of what he had said.
    After about one hour and fifty minutes of questioning had
    elapsed, the defendant reiterated his statement that he had
    bolted from the apartment.    Although his legs were shaking and
    he was tired, the defendant was sufficiently alert after two
    hours of interrogation to divulge the password on his cellular
    telephone and to go through photographs shown to him by police,
    indicating what persons he did and did not recognize.    He was
    also careful to identify one person as "looking like" one of the
    men who had been in the apartment fighting with the victim.
    The defendant had self-protective explanations for, among
    other things, the pain in his groin, the money found in his
    pocket ($1,600), the injury to his upper lip, a fresh scratch,
    the blood on his clothes, the time discrepancies in his
    statements, and his delay in taking the victim to the hospital.
    From the defendant's responses, it was clear that he understood
    what the officers were asking him and saying to him.    He showed
    himself to be quick-witted and consistently self-protective.
    24
    While he added details as the interview proceeded, the defendant
    did not at any point admit any involvement in the victim's
    death.
    After viewing the photographs, the defendant's exhaustion
    began to overcome his ability to speak in a fashion such that
    his statements could be considered the product of a rational
    intellect and free will.   The defendant's physical state,
    compounded by Mulhern's shouting, made it unlikely that the
    defendant's statements from this point onward were the result of
    his free and willing act.16   When left alone for two minutes, the
    defendant moaned and mumbled.   His legs shook badly, and his
    head lolled back and forth.   When the officers returned, about
    two and one-half hours into the interview, the defendant
    continued speaking, but his head was usually facing down and
    leaning to the side.   His legs were constantly shaking.   He did
    not make much eye contact with the officers, and his responses
    were often too inaudible to be coherent.   His demeanor was so
    indicative of someone who had lost his ability to focus that
    Mulhern commented, "I mean you're falling apart . . . doing
    drugs and dealing drugs . . . ."   The defendant was half-asleep,
    and he rubbed his eyes often, yawned, and barely was able to
    16
    The judge specified the page of the transcript of the
    video recording, which had been admitted in two parts at the
    evidentiary hearing, and would have been approximately two hours
    and six minutes into the first recording.
    25
    keep his eyes open.   The questioning, however, did not stop.
    When a few minutes later the defendant asked if they could
    finish the interview the next day, he was rebuffed.    As the
    defendant continued to insist that he was "exhausted out of
    [his] mind," Mulhern started to scream at him again.
    After about two hours and thirty-six minutes of
    questioning, the defendant twice asked for a lawyer, which
    Mulhern and Spencer simply ignored.    Spencer finally ended the
    interview, at which point the defendant was arrested for
    misleading a police officer under the witness intimidation
    statute.   He later was charged with murder in the first degree.
    The motion judge concluded that the defendant had not been
    in "custody" for purposes of the requirements of Miranda v.
    Arizona, 
    384 U.S. 436
    , 444 (1966), until Mulhern instructed that
    the interview at the hospital would continue at the police
    station and directed a uniformed officer to take the defendant
    there.17   The judge further determined that the defendant was in
    custody at the station when he was given Miranda warnings.      The
    judge concluded that after the defendant was given the Miranda
    warnings, he voluntarily, knowingly, and intelligently waived
    17
    Although the defendant did not receive Miranda warnings
    before being escorted to the police cruiser, the judge noted
    that he was not asked any questions and did not make any
    statements during the ride or before the Miranda warnings were
    given to him at the police station.
    26
    them.    She did not consider his initial statement that he would
    "feel more comfortable" with a lawyer as an unambiguous
    invocation of the right to counsel.
    Noting that the defendant's initial waiver of the Miranda
    rights does not irretrievably bind him, the judge pointed out
    that the Commonwealth conceded that the defendant unambiguously
    invoked his right to counsel when he stated after two hours and
    thirty-six minutes of questioning that he needed a lawyer.
    While the judge agreed that the defendant had invoked his right
    to counsel at this point, she determined that somewhat earlier
    in the interrogation (see note 1
    6, supra
    ), the defendant's
    statements were no longer voluntary.    The judge based her
    conclusion on the circumstances of Mulhern's shouting at the
    defendant, the defendant's state of exhaustion, and the after-
    effects of whatever substance the defendant had ingested during
    the day.    Suppression of the defendant's statements from that
    point of the interview and onward therefore was necessary.
    Based on these findings, the motion judge denied in part and
    allowed in part the defendant's motion to suppress.
    b.     Standard of review.   "We review de novo any findings of
    the motion judge that were based entirely on the documentary
    evidence, i.e., the recorded interviews of the defendant."
    Commonwealth v. Thomas, 
    469 Mass. 531
    , 539 (2014).     "We accept
    other findings that were based on testimony at the evidentiary
    27
    hearing and do not disturb them where they are not clearly
    erroneous."   
    Id. "However, we
    'make an independent
    determination as to the correctness of the judge's application
    of constitutional principles to the facts as found.'"      
    Id., quoting Commonwealth
    v. Tremblay, 
    460 Mass. 199
    , 205 (2011).
    c.    Validity of waiver of Miranda rights.    The defendant
    argues that his waiver of Miranda rights was invalid because it
    was not knowingly and voluntarily made.    Because the defendant
    was advised of, and waived, the Miranda rights, the issue
    becomes whether the Commonwealth has proved "the validity of a
    Miranda waiver beyond a reasonable doubt."      Commonwealth v.
    Edwards, 
    420 Mass. 666
    , 669 (1995).    See Commonwealth v. LeBeau,
    
    451 Mass. 244
    , 254-255 (2008).    "To be valid the waiver must be
    made voluntarily, knowingly, and intelligently."     Edwards, supra
    at 670.   "In determining whether a waiver was made voluntarily,
    the court must examine the totality of the circumstances
    surrounding the making of the waiver."    
    Id. "Relevant factors
    to consider include, but are not limited to, 'promises or other
    inducements, conduct of the defendant, the defendant's age,
    education, intelligence, and emotional stability, experience
    with and in the criminal justice system, physical and mental
    condition, the initiator of a deal or leniency (whether the
    defendant or police), and the details of the interrogation,
    including the recitation of Miranda warnings.'"     Commonwealth v.
    28
    Jackson, 
    432 Mass. 82
    , 86 (2000), quoting Commonwealth v.
    Mandile, 
    397 Mass. 410
    , 413 (1986).
    The defendant challenges the judge's conclusion that his
    waiver was valid for several factual reasons, including that he
    had not been asked whether he wished to waive his rights; he had
    not been asked whether he wished to speak with police; and the
    fact that his signature on the notification of rights form
    indicated only that he was advised of the Miranda warnings, not
    that he had waived them.   The defendant also argues that he
    "obviously" was undergoing drug withdrawal.   We conclude that
    the judge's findings and conclusions are supported by the
    evidence.
    The defendant signed the notification of rights form, which
    expressly indicates that the person signing understands the
    Miranda rights and "knowingly waive[s]" those rights; heard the
    recitation of the Miranda warnings; and nodded, which reasonably
    could be inferred as indicating that he understood them.
    Thereafter, he engaged in discussion with the officers.     "This
    conduct hardly expressed an unwillingness to continue speaking
    with police that could be 'considered tantamount to the exercise
    of the right to remain silent.'"   Commonwealth v. Garcia, 
    443 Mass. 824
    , 833 (2005), quoting Commonwealth v. Selby, 
    420 Mass. 656
    , 662 (1995).   Further, during the admitted portion of the
    interview, the defendant appeared alert, coherent, calm for the
    29
    most part, and appropriately responsive, and appeared to
    understand the situation and what was asked of him.    He was
    drinking a beverage, and the interview was conducted in an
    interview room as opposed to a cell.     Although the defendant
    very well may have been under the influence of drugs, there was
    no evidence that the defendant's resulting physical condition
    was so disabling as to render his waiver invalid.     The judge
    thoroughly considered the evidence concerning the defendant's
    likely drug use, which does not compel a conclusion that his
    Miranda waiver was invalid.   See Commonwealth v. Howard, 
    469 Mass. 721
    , 728 n.7 (2014), and cases cited; Commonwealth v.
    Walker, 
    466 Mass. 268
    , 274-275 (2013).    See also Commonwealth v.
    Brown, 
    462 Mass. 620
    , 625-627 (2012).    The evidence supports the
    judge's conclusion that the defendant's Miranda waiver was
    valid.18
    d.    Invocation of right to counsel.   The defendant contends
    that the motion judge erred in concluding that his statement,
    made after he was given the Miranda warnings, "I would feel more
    comfortable if I had a lawyer right now talking, but if you want
    18
    Based on our independent review of the video recording of
    the interview, the judge was warranted in concluding beyond a
    reasonable doubt that the defendant's statements, made up until
    the point where she suppressed them, were made voluntarily. See
    Commonwealth v. Medeiros, 
    395 Mass. 336
    , 343 (1985) (although
    voluntariness and Miranda waiver and voluntariness of statement
    are distinct inquiries, totality of circumstances test under
    each analysis is same).
    30
    to show me pictures and names, I'll give it to you," was an
    ambiguous and therefore ineffective invocation of the right to
    counsel.    We reject the defendant's contention.
    During a custodial interrogation, "[i]f the accused
    indicates that he wishes to remain silent, 'the interrogation
    must cease.'    If he requests counsel, the interrogation must
    cease until an attorney is present."     Commonwealth v. Santos,
    
    463 Mass. 273
    , 285 (2012), quoting Edwards v. Arizona, 
    451 U.S. 477
    , 481 (1981).    The request or invocation of counsel must be
    "a sufficiently clear statement such 'that a reasonable police
    officer in the circumstances would understand the statement to
    be a request for an attorney.'"     Commonwealth v. Hoyt, 
    461 Mass. 143
    , 150 (2011), quoting Davis v. United States, 
    512 U.S. 452
    ,
    459 (1994).
    Here, the defendant's statement, when viewed in context,
    was not an unambiguous request for counsel and reflected a
    desire ultimately to go forward with questioning without an
    attorney.     "When a suspect's statement . . . simply reflects his
    musing about the possibility of stopping the questioning until
    he has spoken with an attorney, we have consistently found the
    statement to be too ambiguous to constitute an unequivocal
    invocation of the right to counsel."     Commonwealth v. Morganti,
    
    455 Mass. 388
    , 398 (2009), S.C., 
    467 Mass. 96
    , cert. denied, 135
    
    31 S. Ct. 356
    (2014).    We conclude that the defendant's statement
    falls into this category.
    The defendant further argues that, even if his invocation
    of the right to counsel had been ambiguous, the police were
    required under art. 12 of the Massachusetts Declaration of
    Rights to clarify the defendant's intent before proceeding with
    questioning.   In support of this contention, he cites to
    Commonwealth v. Clarke, 
    461 Mass. 336
    , 349 (2012), and 
    Santos, 463 Mass. at 286
    .    Those cases, however, do not support the
    defendant's argument that such a clarification was required
    here.   In Santos, supra at 285-286, we suggested clarification
    as the better practice because the defendant initially had
    unequivocally invoked his right to counsel but then continued,
    without any intervening comment or question by police, to speak.
    We concluded that, in those circumstances, the police could have
    been uncertain concerning the nature and scope of the
    defendant's invocation, and before recommencing questioning
    would be "entitled to ask a question to clarify the defendant's
    intent."   
    Id. at 286.
      In Clarke, supra at 343, we dealt with a
    defendant's unequivocal invocation of his right to remain
    silent, not an invocation of a right to counsel.   No
    clarification is required where, as the judge found here, the
    defendant equivocated, stating only that he would "feel more
    comfortable with an attorney."
    32
    e.   Statutory right to a telephone call.    We reject the
    defendant's argument that his statements during the interview
    should be suppressed because the police did not afford him his
    statutory right under G. L. c. 276, § 33A, to use the telephone
    when he arrived at the police station or after questioning had
    exceeded one hour.    This right "did not accrue until he was
    formally arrested."    Commonwealth v. Hampton, 
    457 Mass. 152
    , 159
    (2010).   See Commonwealth v. Dagley, 
    442 Mass. 713
    , 719 (2004),
    cert. denied, 
    544 U.S. 930
    (2005); Commonwealth v. Rivera, 
    441 Mass. 358
    , 374-375 (2004).
    f.   Detention of the defendant.    For the first time on
    appeal the defendant argues that his involuntary transport to
    the police station for questioning amounted to an unlawful
    arrest under the Fourth and Fourteenth Amendments to the United
    States Constitution and art. 14 of the Massachusetts Declaration
    of Rights because it was not supported by probable cause.19       He
    asserts that the entirety of his interview with police therefore
    should be suppressed as the fruit of the illegal arrest.    Last,
    the recitation of the Miranda warnings, he contends, did not
    purge the taint of the illegal arrest.    Because the defendant
    did not raise this claim below, we review for error and, if so,
    19
    The defendant does not argue that art. 14 of the
    Massachusetts Declaration of Rights affords him any greater
    protection than that afforded by the Fourth and Fourteenth
    Amendments to the United States Constitution.
    33
    whether the error caused a substantial likelihood of a
    miscarriage of justice.   See Commonwealth v. Tu Trinh, 
    458 Mass. 776
    , 782-783 (2011).
    Generally speaking, there are three categories of police-
    citizen encounters:    "(1) consensual encounters which do not
    implicate the Fourth Amendment;[20] (2) investigative detentions
    which are Fourth Amendment seizures of limited scope and
    duration which must be supported by a reasonable suspicion of
    criminal activity[,21 Terry v. Ohio, 
    392 U.S. 1
    (1968);] and (3)
    arrests, the most intrusive of Fourth Amendment seizures and
    reasonable only if supported by probable cause."     United States
    v. Madden, 
    682 F.3d 920
    , 925 (10th Cir. 2012).     Here, the
    judge's decision did not address the issue (because the
    20
    Submission to a claim of authority is not synonymous with
    voluntary consent. See Kaupp v. Texas, 
    538 U.S. 626
    , 631
    (2003); United States v. Perez-Montanez, 
    202 F.3d 434
    , 438 (1st
    Cir.), cert. denied, 
    531 U.S. 886
    (2000). There was no evidence
    that the officers told the defendant that he was free not to
    enter the cruiser to go to the police station.
    21
    The parameter of an investigatory stop is exceeded if it
    "continues indefinitely[;] at some point it can no longer be
    justified as an investigative stop." United States v. Sharpe,
    
    470 U.S. 675
    , 685 (1985). While "the brevity of the invasion of
    the individual's Fourth Amendment interests is an important
    factor in determining whether the seizure is so minimally
    intrusive as to be justifiable on reasonable suspicion," United
    States v. Place, 
    462 U.S. 696
    , 709 (1983), the Supreme Court has
    emphasized "the need to consider the law enforcement purposes to
    be served by the stop as well as the time reasonably needed to
    effectuate those purposes," 
    Sharpe, supra
    .
    34
    defendant did not make the argument below), but her findings
    instruct our conclusion.
    The judge found that once Mulhern determined that further
    questioning would continue at the police station and directed an
    officer to transport the defendant there, the defendant was in
    custody, albeit for purposes of Miranda.    She further found,
    based on the notification of rights form designating the
    defendant as a "person in custody," and statements made by the
    interviewing officers, that a reasonable person in the
    defendant's position would not have felt free to leave.    We
    agree with the defendant that, in these circumstances, his
    involuntary transport and detention for interrogation purposes
    amounted to a "seizure" for Fourth Amendment purposes and became
    the functional equivalent of an arrest.22
    In Kaupp v. Texas, 
    538 U.S. 626
    , 629 (2003), the United
    States Supreme Court stated the settled rule that "involuntary
    22
    The judge expressly discredited Taunton police Detective
    Shawn Mulhern's testimony that the defendant acquiesced or
    actually agreed to go to the police station for questioning.
    Cf. Commonwealth v. Cruz, 
    373 Mass. 676
    , 683 (1977) (no illegal
    detention of defendant where defendant consented to enter police
    cruiser and go to station for questioning). We add that there
    was no evidence that Mulhern sought to relocate the defendant to
    the police station for safety or security issues. Cf. Florida
    v. Royer, 
    460 U.S. 491
    , 504-505 (1983) ("there are undoubtedly
    reasons of safety and security that would justify moving a
    suspect from one location to another during an investigatory
    detention, such as from an airport concourse to a more private
    area").

    transport to a police station for questioning is 'sufficiently
    like arres[t] to invoke the traditional rule that arrests may
    constitutionally be made only on probable cause.'"

    v. Royer, 
    460 U.S. 491
    , 503 (1983) (concluding that airport
    detention exceeded limits of investigatory stop and amounted to
    de facto arrest); Dunaway v. New York, 
    442 U.S. 200
    , 212 (1979)
    (concluding that where petitioner was taken from neighbor's home
    to police vehicle, transported to police station, and placed in
    interrogation room, detention was "indistinguishable" from
    traditional arrest and required probable cause or judicial
    authorization); United States v. Ryan,

    , 487
    (D. Mass. 2010) (stating that limitation on valid investigatory
    stop is that suspect may not be removed to police station
    without his or her consent).   Indeed, "the line is crossed when
    the police, without probable cause or a warrant, forcibly remove
    a person from his home or other place in which he is entitled to
    be and transport him to the police station, where he is
    detained, although briefly, for investigative purposes."

    .   "In the name of investigating a person who is no more
    than suspected of criminal activity, the police may not . . .

    conditions of an arrest."

    .   "Nothing is
    more clear than that the Fourth Amendment was meant to prevent
    36
    wholesale intrusions upon the personal security of our
    citizenry, whether these intrusions be termed 'arrests' or

    station house questioning, such custodial detention requires
    probable cause as it is equivalent to formal arrest;
    investigatory detentions not requiring probable cause must be

    probable cause).   Many United Stated Circuit Courts of Appeals
    have followed this precedent.23

    Because there was no probable cause to arrest the
    defendant24 or judicial authorization to do so, "well-established
    precedent requires suppression of the [statement] unless that
    [statement] was 'an act of free will [sufficient] to purge the
    primary taint of the unlawful invasion.'"

    , quoting Wong Sun v. United States, 
    371 U.S. 471
    , 486
    (1963).   See Commonwealth v. Damiano, 
    444 Mass. 444
    , 453 (2005).
    Demonstrating that the underlying illegality is purged from
    taint falls on the Commonwealth.   See Kaupp, supra at 633;
    Damiano, supra at 454.   Relevant considerations include "(1) the
    temporal proximity of the admission to the arrest; (2) the
    presence of intervening circumstances between the arrest and the
    admission; (3) the observance of the Miranda rule subsequent to
    the unlawful arrest; and (4) the purpose and flagrancy of the
    official misconduct."    Damiano, supra at 455.   The observance of
    the Miranda rule standing alone is insufficient to remove the
    taint of an unlawful detention.    See Kaupp, supra; Commonwealth
    v. Bradshaw, 
    385 Mass. 244
    , 258 (1982).
    Although the officers recited the Miranda warnings to the
    defendant, consideration of the remaining factors reveals little
    to no attenuation between the arrest and interrogation.    The
    defendant was questioned within ten minutes of arriving at the
    24
    The Commonwealth concedes this point, and the judge's
    findings warrant it, as the officers testified that the
    defendant had not yet become a suspect in the victim's killing.
    38
    police station, and no intervening circumstances occurred before
    the interview commenced.   Further, in transporting the defendant
    to the police station for interrogation, the police sought
    expediently to confirm or to dispel whether the defendant had
    involvement in the victim's death.    On balance of the factors,
    we conclude that the Commonwealth has not satisfied its burden
    here.
    Our conclusion that the defendant's statement resulted from
    an unlawful arrest does not end our inquiry.   We must determine,
    under the circumstances, whether the erroneous admission of the
    defendant's interview with police (the portion that the motion
    judge did not suppress) created a substantial likelihood of a
    miscarriage of justice.    See Commonwealth v. Gonzalez, 
    469 Mass. 410
    , 417 (2014).    The relevant inquiry is whether the jury's
    verdict finding that the defendant was guilty of felony-murder
    would likely have been the same had the interview been
    suppressed.   
    Id. The defendant
    argues that his recorded interview was the
    "clearest and least equivocal evidence that any robbery or
    attempted robbery actually took place in the apartment."    We
    disagree.   The evidence, apart from the defendant's statements
    to the police during the recorded interview, was strongly
    supportive of the Commonwealth's theory that the defendant had
    participated in a joint venture to rob the victim on the night
    39
    of the murder.   We recount the relevant evidence below to
    illustrate the point.
    The defendant had already told police at the hospital that
    the victim was at the apartment for a drug deal; that three men
    entered, some of whom had guns; that the defendant escaped
    downstairs to his sister's apartment; and that, after the men
    left, the defendant found the victim alive, but badly beaten.
    Thus, the purpose of the encounter with the victim did not
    derive solely from the defendant's recorded interview.
    Although the defendant denied any involvement in the crime,
    it was the defendant's wife who firmly placed the defendant in
    the midst of the scheme to rob the victim.   Her testimony that
    the defendant instructed the victim to meet at Stenstream's
    apartment instead of his wife's apartment as originally planned;
    that the defendant packaged between $42,000 and $58,000 in cash
    and took it with him when he left to meet the victim; and that
    the defendant questioned someone on the telephone before he left
    for Stenstream's apartment as to whether he was "going to get it
    back" established the defendant as a willing and necessary
    participant in the plot to rob the victim.   Also, Matteson's
    testimony that Morin, the day before the killing, had informed
    him of a plot involving Morin, the defendant, and others to rob
    the victim at an apartment owned by the defendant further
    corroborated the defendant's wife's extremely damaging
    40
    testimony.   From this testimony, the jury reasonably could have
    inferred that the defendant was involved in a robbery or
    attempted robbery of the victim.
    To be sure, some of the defendant's statements in his
    recorded interview added information that the jury did not hear
    or learn elsewhere at trial.    For instance, in the recorded
    interview the defendant stated that the victim told the three
    men that they owed him money and that the victim had a large
    plastic bag in his pocket that contained drugs.    This
    information, however, did not implicate the defendant in the
    robbery or attempted robbery.
    While the defendant's recorded interrogation added for the
    first time that one of the men hit the victim with a gun, that
    detail did not add anything of significant value, as the
    defendant kept to his story that he "bolted" as soon as he had
    the opportunity and that he did not have any involvement with
    the three men and the incident that occurred.
    Also, the defendant's admission in his recorded interview
    that $1,000, from the $1,600 discovered on his person that
    night, was payment from the victim for use of the apartment was
    not relevant to the defendant's participation in a robbery or
    attempted robbery of the victim.    Rather, the admission
    concerning the money only strengthened the Commonwealth's
    existing evidence that the defendant was at that time, contrary
    41
    to his statements, still involved in drug dealing and perhaps
    even this particular drug deal.   None of the defendant's
    statements suggested that the drug deal was a ruse for a robbery
    or attempted robbery.   That suggestion came from Matteson during
    his trial testimony.
    We turn now to the information obtained from the
    defendant's cellular telephone, which the defendant argues
    derived from the illegal interrogation.   While at the hospital
    when he was not in custody, the defendant granted permission to
    police to look at his cellular telephone.   From this
    examination, police learned that the defendant's cellular
    telephone recently had been in communication with Morin's
    telephone numerous times.   Further, as we have already noted,
    the defendant's wife testified about communications between
    Morin and the defendant on the day before the victim's death,
    and a telephone call from Morin looking for the defendant after
    something had "happened" with "that kid" who was "tough."    Also,
    telephone records of Morin's cellular telephone independently
    supported the prosecutor's suggestion that the telephones of the
    two men had been in frequent communication before and after the
    victim's death.   The defendant's telephone records were
    cumulative of Morin's records and other evidence, and any effect
    on the jury from their admission thus was minimal.
    42
    A close examination of the defendant's statements in the
    recording shows that his statements strengthened the
    Commonwealth's claim that the defendant was involved in drugs
    and drug dealing, but not in a robbery or attempted robbery of
    the victim.   Concerning the robbery or attempted robbery, the
    interview bore little on the jury's determination that the
    defendant was a joint venturer in the robbery or attempted
    robbery of the victim.   The significant evidence, which the
    defendant overlooks, was the testimony of his sister and her
    husband regarding what they heard that night above them; his
    wife's testimony regarding the events of the night; and
    Matteson's testimony that Morin had revealed to Matteson what
    had been planned and who was involved the day before the
    victim's death.   In these circumstances, we conclude that no
    substantial likelihood of a miscarriage occurred by the
    erroneous admission of the defendant's statements made during
    his interview with police.
    2.   Motion to withdraw.   The defendant argues that the
    judge erred in "forcing" him to trial with defense counsel who
    unsuccessfully had sought to withdraw his representation of the
    defendant just two days before trial.   He further contends that
    he was deprived of the effective assistance of trial counsel
    because he was forced to stand trial with defense counsel who
    43
    did not want to represent him and who purportedly had admitted
    to preparing his defense at a "low level."
    On October 29, 2012, which was two days prior to trial,
    defense counsel, who was retained by the defendant and his
    family, filed a motion to withdraw.   In support of that motion,
    defense counsel filed an affidavit stating the following.
    Communication between defense counsel and the defendant had
    "broken down."   Defense counsel had learned that the defendant
    recently had accused him of "jamming him up," not preparing his
    case, and forcing him to accept a plea to murder in the second
    degree.   The defendant had telephoned his office on October 25
    and had told an associate that he was dissatisfied with defense
    counsel's representation and no longer wished for him to serve
    as his trial counsel.   Defense counsel indicated that the
    defendant felt that counsel was not acting in the defendant's
    best interests; that he had not properly prepared the
    defendant's case; and that, by advising the defendant to take a
    plea, he had abandoned the defendant's case.    Defense counsel
    stated that the defendant wanted to be heard by the court and
    that he had advised the defendant and his family that they
    needed to arrange for successor counsel.     Defense counsel went
    on to state that, notwithstanding the defendant's position, he
    was continuing to prepare the case for trial.    Defense counsel
    also represented that, with several exceptions regarding some
    44
    specific pretrial preparation (preparing a witness list, for
    example), he had been fully prepared for trial prior to the
    defendant's telephone call on October 25.
    The judge, who was also the trial judge, held a hearing on
    October 29.   The defendant explained:
    "I no longer trust [defense counsel], I lost all my
    faith in him. I feel [that he] hasn't taken my best
    interest, fifteen to life, when I'm one hundred per cent
    innocent. He also told me he'll put no more effort into my
    case. I'm indigent. And I have lawyers that state that,
    your Honor. On top of that, writing letters that you're
    going to proceed on my trial at a low level."
    The defendant added that he was dissatisfied because he
    requested, but was not afforded, either an expert to review the
    medical examiner's autopsy report or a private investigator to
    speak with "a few people."   The defendant also wanted "some
    motions in" after he "lost" the suppression motion.
    The letters to which the defendant referred included one
    dated October 15, 2012, from defense counsel to the defendant,
    which the defendant submitted to the judge.    In the one-page
    letter, defense counsel expressed concern regarding the large
    amount owed for his services and expenditures.     Defense counsel
    also wrote, "Much work remains on your case although I am ready
    on a low level.   I feel however you want additional work and I
    am willing to provide it subject to me getting paid."
    Defense counsel confirmed at the hearing that he had sent
    the defendant the October 15 letter.     He explained what he meant
    45
    by the phrase "low level," which included preparing indexes for
    every police report, every grand jury hearing, and every other
    hearing, including the extensive suppression hearing.    "Low
    level" preparation, according to defense counsel, did not
    constitute extensive trial preparation, which involves working
    "day and night" and weekends in order to try the case when the
    trial date is firm.    When defense counsel authored the letter,
    he was not yet conducting actual trial preparation.
    Defense counsel told the judge that communication between
    him and the defendant deteriorated for several reasons,
    including that the defendant refused to accept the impact of our
    decision in Commonwealth v. Zanetti, 
    454 Mass. 449
    , 466-468
    (2009), which effectively erased the distinction between
    principal and joint liability with regard to joint venture
    liability.   In addition, defense counsel informed the judge that
    he had consulted at least two doctors to review the autopsy
    report, and the defendant did not want to accept their opinions
    that there was no basis to dispute the victim's cause of death.
    The defendant also "reject[ed] entirely" the fact that his wife,
    who apparently was not going to testify against him, had changed
    her mind and would be testifying "to some major things that are
    very problematic."    Another damaging fact that the defendant
    refused to accept was his sister Lucia's expected testimony
    that, on the night of the killing, after the group had run out
    46
    of Stenstream's apartment, she heard the defendant and another
    voice from Stenstream's apartment, which was significant because
    the testimony supported an inference that the victim had been
    alive and alone with the defendant.   Defense counsel stated that
    his plea recommendation had nothing to do with "the payment of
    fees, but an evaluation of the evidence."25
    Defense counsel sought to withdraw, but stated he would "do
    [his] best" were the judge to order him to proceed.   The judge
    ruled that the defendant had the right to bring in new counsel
    "provided new counsel is prepared to impanel this case [in two
    days]."   The judge noted that the case commenced in "the early
    portion of 2010" and that the Commonwealth "can be prejudiced by
    the denial of a speedy trial as its witnesses' memories may dull
    and wane by the passage of time."   The judge added that the
    motion judge had actually agreed with defense counsel regarding
    a portion of the motion to suppress, so that it was not fair to
    25
    Without citation to any authority, the defendant's
    appellate counsel suggests that the defendant's trial counsel
    revealed communications that were protected by the attorney-
    client privilege. We have stated, however, where a defendant
    "essentially accuse[s] trial counsel of incompetence in
    circumstances covered by the attorney-client privilege and to
    which the only witnesses were the defendant and trial counsel,
    the privilege must be deemed waived, in part, to permit counsel
    to disclose only those confidences necessary and relevant to the
    defense of the charge of ineffective assistance of counsel."
    Commonwealth v. Silva, 
    455 Mass. 503
    , 529 (2009), and cases
    cited. Here, defense counsel acted appropriately, revealing
    communications that were responsive and relevant to the
    defendant's claims of ineffective assistance.
    47
    state that the motion had been lost.    The judge stated that an
    attorney is not to "operate simply as an accommodating party"
    and is required to be effective in plea negotiations in addition
    to a trial.   He validated the challenges defense counsel faced
    based on the circumstances and facts of the case.    Last, the
    judge rejected the accusation that defense counsel had abandoned
    the defendant, pointing to his voir dire questions and motions
    in limine that had been filed.
    The judge declined to continue the case to permit the
    defendant to obtain new counsel.    The defendant stated that he
    did not see how it could be possible to try the case in two days
    with new counsel.   The judge denied the motion to withdraw.
    We review the denial of a motion to withdraw counsel for
    abuse of discretion.     Commonwealth v. Rice, 
    441 Mass. 291
    , 297
    (2004).   We also review the denial of a request for a
    continuance for abuse of discretion.     Commonwealth v. Ray, 
    467 Mass. 115
    , 128 (2014).
    "The Sixth Amendment [to the United States Constitution]
    guarantees the right to effective assistance of counsel, but it
    'does not invariably require a "meaningful attorney-client
    relationship."'"    Commonwealth v. Britto, 
    433 Mass. 596
    , 600
    (2001), quoting Commonwealth v. Tuitt, 
    393 Mass. 801
    , 806
    (1985).   "Freedom to change counsel . . . is restricted on the
    commencement of trial."    Commonwealth v. Chavis, 
    415 Mass. 703
    ,
    48
    711 (1993).   "A motion to discharge counsel, when made on the
    eve of trial, or on the day on which trial is scheduled to
    begin, 'is a matter left to the sound discretion of the trial
    judge.'"   Tuitt, supra at 804, quoting Commonwealth v. Moran,
    
    388 Mass. 655
    , 659 (1983).    There is no "mechanical test" that
    applies.   
    Chavis, supra
    .    A trial judge is to "balance the
    movant's need for additional time against the possible
    inconvenience, increased costs, and prejudice which may be
    incurred by the opposing party if the motion is granted.     He
    must also give due weight to the interest in the judicial system
    in avoiding delays which would not measurably contribute to the
    resolution of a particular controversy."     
    Id., quoting Commonwealth
    v. Cavanaugh, 
    371 Mass. 46
    , 51 (1976).
    Turning to requests for continuances, we have explained
    that "there is no 'mechanical test' for determining whether the
    denial of a continuance constitutes an abuse of discretion
    because we must examine the unique circumstances of each case,
    particularly the reasons underlying the request."     Commonwealth
    v. Pena, 
    462 Mass. 183
    , 190 (2012).    "A judge should grant a
    continuance only when justice so requires, balancing the
    requesting party's need for additional time against concerns
    about inconvenience, cost, potential prejudice, and the burden
    of the delay on both the parties and the judicial system."        
    Ray, 467 Mass. at 128
    .   "[C]ognizant of a criminal defendant's
    49
    constitutional entitlement to assistance of counsel, who 'must
    be afforded "a reasonable opportunity to prepare and to present
    the defence,"'" 
    id. at 128-129,
    quoting 
    Cavanaugh, 371 Mass. at 50
    , we have cautioned that "a trial judge may not exercise his
    discretion in such a way as to impair" this right.   Ray, supra
    at 129, quoting Commonwealth v. Miles, 
    420 Mass. 67
    , 85 (1995).
    Here, the judge gave the defendant the opportunity to
    explain his reasons for his dissatisfaction with defense counsel
    and acted within his discretion in denying both the motion to
    withdraw and the request for a continuance.   See 
    Chavis, 415 Mass. at 712
    (judge gave defendant "fair opportunity to explain
    the reasons for his dissatisfaction with trial counsel").    The
    judge appropriately gave consideration to the facts that the
    case was scheduled for trial in two days, the defendant had been
    indicted some two years earlier, and he had not engaged
    successor counsel.   The judge did not misstate the law
    concerning a defendant's right to a speedy trial, but rather, in
    context, properly considered the defendant's needs against the
    legitimate needs of judicial administration, including the need
    for witness testimony to be unhindered due to the passage of
    time.   See Commonwealth v. Gilchrest, 
    364 Mass. 272
    , 276 (1973).
    The judge could properly take such matters into account even in
    the absence of evidence of a calculated effort made by the
    defendant to postpone the trial.
    50
    The judge considered the nature and seriousness of the
    conflict between the defendant and his counsel.   See 
    Rice, 441 Mass. at 297
    .   Implicit in the judge's conclusion was that he
    credited defense counsel's explanation of what he meant by using
    the phrase "low level."   Further, the judge credited defense
    counsel's statements that he was prepared for trial, noting his
    extensive trial preparation efforts, namely the motions he had
    filed on the defendant's behalf and the filings submitted in
    preparation of jury empanelment.   Cf. 
    Cavanaugh, 371 Mass. at 48
    , 57 (error to deny continuance where defense counsel stated
    he was not prepared).   The judge explored the allegations that
    defense counsel had not met all of the defendant's demands,
    finding them unreasonable or unsupported in the circumstances.
    For these reasons, there is no basis for the defendant's
    argument that the judge abused his discretion in failing to
    reach a different conclusion, namely, that defense counsel had
    "washed his hands" of the defendant and was willing to put in
    only minimal effort for trial.   See 
    Britto, 433 Mass. at 601
    (stating that counsel's failure to meet all of defendant's
    demands does not equate with "an irreconcilable breakdown of
    communication").
    Last, concerning the defendant's claim that he was deprived
    of the effective assistance of trial counsel because he was
    forced to stand trial with defense counsel who did not want to
    51
    represent him and who purportedly had admitted to preparing his
    defense at a "low level," the "ultimate question is whether the
    defendant likely would be denied the effective assistance of
    counsel if counsel is not removed."     
    Id. Based on
    the record
    before us, we conclude that the defendant has failed to make the
    requisite showing.
    3.   Ineffective assistance of counsel.      The defendant's
    ineffective assistance of counsel argument is predicated on the
    claims of error we have already addressed and, thus, lacks
    merit.
    4.   Relief pursuant to G. L. c. 278, § 33E.       Pursuant to
    our statutory duty, we discern no basis to reduce the verdict or
    to order a new trial pursuant to G. L. c. 278, § 33E.
    Conclusion.   We reverse the order denying in part the
    defendant's motion to suppress statements.     We affirm the order
    denying defense counsel's motion to withdraw.       We affirm the
    defendant's conviction.
    So ordered.
