    GAZIANO, J.   In this case, we consider whether police
    officers were required to provide Miranda warnings prior to
    questioning two individuals who had been detained in a
    restaurant parking lot as part of a threshold inquiry into a
    street-level drug transaction.   A Middlesex County grand jury
    indicted the defendants, Keith Cawthron and Craig Flodstrom, on
    charges of trafficking in Oxycodone, in violation of G. L.
    c. 94C, § 32E (c) (1), and conspiracy to traffic Oxycodone, in
    violation of G. L. c. 94C, § 40.   The defendants filed motions
    to suppress statements made to detectives and pills found in one
    of the defendants’ vehicles, arguing that they had been subject
    to custodial interrogation without adequate Miranda warnings,
    and the seizure of the pills was a result of custodial
    statements given absent such warnings.   A Superior Court judge
    concluded that the defendants had been subject to custodial
    interrogation without, in Cawthron's case, any warnings and, in
    3
    Flodstrom's case, an inadequate warning, and allowed the motions
    to suppress.2
    The Commonwealth filed a timely notice of appeal.      A single
    justice of this court allowed the Commonwealth's application for
    leave to pursue an interlocutory appeal and reported the matter
    to the Appeals Court.     The Appeals Court issued an opinion
    reversing the judgment of the Superior Court.      See Commonwealth
    v. Cawthron, 
    90 Mass. App. Ct. 828
    (2017).      We allowed the
    defendants' petitions for further appellate review.
    Applying the factors set out in Commonwealth v. Groome, 
    435 Mass. 201
    , 211–212 (2001), we conclude that the defendants were
    not subject to custodial interrogation.      Therefore, the Superior
    Court judge's decision allowing the motions to suppress must be
    reversed.
    1.     Background.   We summarize the facts as found by the
    motion judge following an evidentiary hearing.      We indicate
    explicitly those few facts the judge found that are not
    supported by the record.
    On April 12, 2013, Detective Michael Donovan of the
    Tewksbury police department stopped at a convenience store on
    2 The judge denied Flodstrom's motion to suppress statements
    that he made when officers first approached him, before they had
    asked any questions, but allowed the motion to suppress all
    statements made after the officers began asking questions.
    4
    Route 133 in Tewksbury.     Donovan was dressed in plain clothes
    and was driving an unmarked vehicle.     As he was walking across
    the parking lot toward the store, Donovan overheard a man, later
    identified as Cawthron, speaking on a cellular telephone outside
    the store.    Cawthron said that he was "going to pick them up
    now," and asked, "How many do you want" and, "Do you want ten?"
    Donovan suspected that Cawthron was arranging a narcotics
    transaction.     After purchasing a beverage in the store, Donovan
    returned to his vehicle and waited for Cawthron to leave the
    store.   Donovan then followed Cawthron's vehicle as it left the
    parking lot.
    Cawthron traveled a short distance on Route 133, and then
    turned into the parking lot of a fast food restaurant.     After
    briefly losing sight of the defendant's vehicle, Donovan located
    it in a nearby steakhouse parking lot; Cawthron was standing
    outside his vehicle, speaking on his cellular telephone.
    Donovan parked his vehicle fifteen or twenty yards from
    Cawthron's.
    Donovan contacted Detective Lieutenant Ryan Columbus of the
    Tewksbury police department and informed him of the
    investigation.    Columbus arrived, also in an unmarked vehicle,
    and established surveillance from a nearby parking lot.
    Approximately five minutes later, a black vehicle entered
    the steakhouse parking lot and parked next to Cawthron's
    5
    vehicle.   Flodstrom got out of this vehicle and approached
    Cawthron; the men shook hands and exchanged items that Donovan
    could not see.    Based on these actions, the statement he had
    overheard in the convenience store parking lot, and his
    knowledge that the parking lots along Route 133 were often used
    for illegal drug transactions, Donovan believed this to be a
    hand-to-hand drug transaction.
    Donovan got out of his unmarked vehicle, walked quickly to
    where the two men were standing, and identified himself as a
    police officer.   He ordered the men not to move.   At that point,
    Flodstrom said, "[T]his is how I feed my family."    Columbus
    arrived at the scene shortly after Donovan had reached the
    defendants.   He and Donovan decided to separate the two men and
    question them individually, before they had an opportunity to
    construct a shared response.3    Donovan directed Flodstrom to the
    far side of Flodstrom's vehicle; Cawthron was directed to go
    with Columbus on the far side of Cawthron's vehicle.    Each man
    moved approximately five yards from where he stood before the
    detectives arrived.
    3 At the hearing on the motion to suppress, both detectives
    testified that separating individuals for questioning is a
    standard police tactic, to reduce the possibility that the
    individuals would be able to coordinate their responses.
    6
    Once Donovan and Flodstrom were separated from Cawthron and
    Columbus, Donovan gave Flodstrom an oral Miranda warning.4
    Donovan then asked Flodstrom what had happened.   Flodstrom
    responded that he had sold 300 Oxycodone pills to his uncle,
    Cawthron, for two dollars per pill.   Flodstrom reiterated that
    this was how he fed his children, and pulled $600 from his
    pocket.   After Flodstrom produced the money, Donovan placed him
    in handcuffs and told him that he was under arrest.
    While this interaction was taking place, Columbus spoke
    with Cawthron in front of Cawthron's vehicle.   Columbus
    identified himself as a police officer and asked Cawthron what
    he had purchased.   Cawthron said that he had purchased pills for
    two dollars each.   Columbus asked where the pills were, and
    Cawthron told him the pills were under the seat in his vehicle.
    Columbus looked under the driver's seat and found a full pill
    bottle.   After retrieving the bottle, Columbus handcuffed
    Cawthron, placed him under arrest, and read him his Miranda
    rights.   In response to the detective's further questions,
    Cawthron said that he was acting as the middle man for a friend.
    4 Rather than reading the warnings from a printed card,
    Donovan gave them to the best of his ability from memory. At
    the hearing on the motion to suppress, Donovan was unable to
    recall exactly what he told Flodstrom.
    7
    After handcuffing Cawthron, Columbus took the pill bottle
    to Donovan, who was standing with Flodstrom.5
    Cawthron and Flodstrom were indicted by a Middlesex County
    grand jury on charges of trafficking in over eighteen grams of
    Oxycodone, G. L. c. 94C, § 32E (c) (1), and conspiracy to
    traffic in Oxycodone, G. L. c. 94C, § 40.
    Cawthron and Flodstrom filed motions to suppress their
    statements and the evidence seized.   After an evidentiary
    hearing, the judge found that the detectives had reasonable
    suspicion to stop the defendants and to conduct a threshold
    inquiry; that the defendants were subjected to custodial
    interrogation; and that the Commonwealth failed to prove that
    either Flodstrom or Cawthron received adequate Miranda warnings.
    Accordingly, the judge suppressed all of Cawthron's statements
    and the pill bottle found in his vehicle, and ordered
    Flodstrom's statements suppressed apart from his initial remark
    upon the first detective's arrival that "this is how I feed my
    family."6
    5 The judge found that Columbus showed Donovan and Flodstrom
    the pills before Flodstrom finished making his statements to
    Donovan. As discussed infra, this finding is not supported by
    the record.
    6 The judge also found that Flodstrom had automatic standing
    to challenge the search of Cawthron's vehicle, and thus
    suppressed the pills found in that vehicle with respect to the
    trafficking charge against Flodstrom, but not with respect to
    8
    The Commonwealth's motion to reconsider was denied.     The
    Commonwealth then filed an application in the county court for
    leave to pursue an interlocutory appeal.   A single justice of
    this court allowed the Commonwealth to pursue an interlocutory
    appeal in the Appeals Court.   After the Appeals Court reversed
    the allowance of the motions to suppress, see Cawthron, 90 Mass.
    App. Ct. at 839, we allowed the defendants' petitions for
    further appellate review.
    The Commonwealth argues that the judge committed legal
    error when he determined that the defendants were subjected to
    custodial interrogation that necessitated Miranda warnings.     For
    the reasons that follow, we agree.
    2.   Discussion.   "In reviewing a ruling on a motion to
    suppress, we accept the judge's subsidiary findings of fact
    absent clear error 'but conduct an independent review of his
    ultimate findings and conclusions of law.'"   Commonwealth v.
    Scott, 
    440 Mass. 642
    , 646 (2004), quoting Commonwealth v.
    Jimenez, 
    438 Mass. 213
    , 218 (2002).
    The encounter between the officers and the defendants began
    as a valid Terry-type stop, with an initial, brief inquiry into
    the suspicious transactions that a police officer believed he
    the conspiracy charge. The Commonwealth challenges the
    determination of automatic standing. Because of the result we
    reach, we need not decide this issue.

    had seen.    See Terry v. Ohio, 
    392 U.S. 1
    , 28-29 (1968).   Such
    stops are permissible where an officer has a reasonable
    suspicion that a crime has been, is being, or is about to be
    committed.   See 
    id. At that
    point, the interaction is casual,
    and generally no Miranda warnings are necessary.    See
    Commonwealth v. Borodine, 
    371 Mass. 1
    , 4 (1976).
    At some point, however, the nature of the interaction may
    change, as officers begin to focus on a particular suspect.
    Miranda warnings seek to protect an individual's "fundamental"
    right under the Fifth Amendment to the United States
    Constitution that "[n]o person . . . shall be compelled in any
    criminal case to be a witness against himself."    See Miranda v.
    Arizona, 
    384 U.S. 436
    , 468 (1966).   Miranda warnings require
    that police officers inform suspects of their "right[s] to
    remain silent, that any statement [they] do[] make may be used
    as evidence against [them], and that [they have] a right to the
    presence of an attorney, either retained or appointed," before a
    custodial interrogation.    
    Id. at 444.
      An interview is custodial
    where "a reasonable person in the suspect's shoes would
    experience the environment in which the interrogation took place
    as coercive."   Commonwealth v. Larkin, 
    429 Mass. 426
    , 432
    (1999).   Miranda warnings protect suspects from police-dominated
    environments that were "created for no purpose other than to
    subjugate the individual to the will of his examiner."      See
    10
    Miranda, supra at 457; 
    id. at 474
    ("Without the right to cut off
    questioning, the setting of in-custody interrogation operates on
    the individual to overcome free choice in producing a
    statement)."
    Even where a suspect is temporarily seized, "[n]ot every
    Terry-type investigative stop results in a custodial
    interrogation."   Commonwealth v. DePeiza, 
    449 Mass. 367
    , 375
    (2007), citing Berkemer v. McCarty, 
    468 U.S. 420
    , 440 (1984).
    See 
    Miranda, 384 U.S. at 477
    ("General on-the-scene questioning
    as to facts surrounding a crime or other general questioning of
    citizens in the fact-finding process is not affected by our
    holding"); Commonwealth v. Kirwan, 
    448 Mass. 304
    , 312 (2007)
    (defendant was not in custody, despite not being free to leave,
    where "[the] interrogation was brief and in the nature of a
    preliminary investigation, and the defendant's detention was
    minimal").   "the fact that the defendant was not free to leave
    (at least until the performance of the field sobriety tests) did
    not render the interrogation custodial."   Commonwealth v. Ayre,
    
    31 Mass. App. Ct. 17
    , 20 (1991).   "A person is in custody
    whenever [the person] is deprived of his [or her] freedom of
    action in any significant way" (quotation and citation omitted).
    
    Groome, 435 Mass. at 211
    .   See Commonwealth v. Morse, 
    427 Mass. 117
    , 123 (1998), quoting United States v. Ventura, 
    85 F.3d 708
    ,
    712 (1st Cir. 1996) (custody is "a formal arrest or restraint on
    11
    freedom of movement of the degree associated with a formal
    arrest").     See generally Grasso & McEvoy, Suppression Matters
    under Massachusetts Law § 18-3[b] (2017).
    To determine if a defendant was subjected to custodial
    interrogation, "the court considers several factors:     (1) the
    place of the interrogation; (2) whether the officers have
    conveyed to the person being questioned any belief or opinion
    that that person is a suspect; (3) the nature of the
    interrogation, including whether the interview was aggressive
    or, instead, informal and influenced in its contours by the
    person being interviewed; and (4) whether, at the time the
    incriminating statement was made, the person was free to end the
    interview by leaving the locus of the interrogation or by asking
    the interrogator to leave, as evidenced by whether the interview
    terminated with an arrest."     Commonwealth v. 
    Groome, 435 Mass. at 211
    –212.    "Rarely is any single factor conclusive."
    Commonwealth v. Bryant, 
    390 Mass. 729
    , 737 (1984).
    Applying the Groome factors to the circumstances here, we
    conclude that the defendants have not met their burden of
    showing that they were in custody when they made the
    incriminating statements.    See 
    Larkin, 429 Mass. at 432
    .
    a.   Location of interviews.     To determine if the location
    of an interrogation contributed to a coercive environment, we
    consider the circumstances "from the point of view of the
    12
    defendant."   See Commonwealth v. Conkey, 
    430 Mass. 139
    , 144
    (1999), S.C., 
    443 Mass. 60
    (2004) and 
    452 Mass. 1022
    (2008).
    The detectives questioned the defendants in a public parking
    lot, during the day, and the defendants were neither handcuffed
    nor otherwise physically restrained.   This environment is not
    police-dominated.   See Vanhouton v. Commonwealth, 
    424 Mass. 327
    ,
    331-332 & n.7, cert. denied, 
    522 U.S. 834
    (1997), quoting
    Pennsylvania v. Bruder, 
    488 U.S. 9
    , 11 n.3 (1988) (suspect
    stopped on suspicion of operating motor vehicle while under
    influence of alcohol and subject to field sobriety tests on side
    of road was not in custody, because, in part, "traffic stops
    commonly occur in the 'public view,' in an atmosphere far 'less
    "police dominated" than that surrounding the kinds of
    interrogation at issue in Miranda itself'").   Cf. United States
    v. Jones, 
    187 F.3d 210
    , 218 (1st Cir. 1999) ("a public highway
    is a neutral setting that police officers are not in a position
    to dominate").
    In this case, the detectives instructed the defendants to
    move approximately five yards from where they had been
    conversing in the restaurant parking lot, so that each detective
    would be able to speak with one of the defendants individually.7
    7 Flodstrom argues that the defendants' compliance with this
    instruction demonstrates that they did not believe they had any
    choice but to obey the detectives' orders. Even assuming that
    13
    This movement did not result in a coercive atmosphere.8    See
    
    Vanhouton, 424 Mass. at 331-332
    (officer's instruction to driver
    to get out of vehicle and perform field sobriety tests did not
    create coercive atmosphere).
    Other courts likewise have concluded that moving
    individuals a short distance, so as to interview them
    separately, does not constitute custodial interrogation.      In
    United States v. Campbell, 
    741 F.3d 251
    , 267 (1st Cir. 2013),
    for example, three individuals were traveling in a vehicle that
    was stopped by police.   Approximately five police officers
    "split up and questioned the defendants separately, such that
    each defendant was questioned by at most two officers."    
    Id. The United
    States Court of Appeals for the First Circuit held
    that the officers' decision to separate the defendants, even
    where some were interrogated by multiple police officers, did
    not create an "overwhelming" environment that was custodial and
    the movement was forced, however, does not necessarily result in
    a conclusion that the defendants were in custody for purposes of
    Miranda. See 
    Larkin, 429 Mass. at 432
    (defendants have burden
    to establish that they were subject to custodial interrogation;
    restriction on freedom of movement does not necessarily amount
    to custody).
    8 Flodstrom also argues that his difficulty walking added to
    the coercive nature of the situation. The judge did not make
    any findings about Flodstrom's physical condition, although
    Donovan testified that Flodstrom had a limp and appeared to have
    some difficulty moving. No evidence in the record indicates
    that the short distance involved placed a significant burden on
    Flodstrom, such that his detention was custodial.
    14
    necessitated Miranda warnings.   See 
    id. We agree;
    the act of
    separating defendants briefly for individual questioning does
    not create an inherently coercive environment.
    b.   Whether the detectives conveyed a belief that the
    defendants were suspects.   If the detectives had conveyed to the
    defendants that they were suspects, that might support a
    determination that the defendants were in custody before they
    made the incriminating statements.    See Commonwealth v. Simon,
    
    456 Mass. 280
    , 287-288, cert. denied, 
    562 U.S. 874
    (2010).     When
    they approached the defendants, one of the detectives asked one
    of the defendants what he had just purchased, a question the
    defendants maintain indicates that the detectives believed the
    defendants had been involved in a public drug transaction.     We
    do not agree.   The interview occurred as part of the detectives'
    "brief, preliminary effort to confirm or dispel a suspicion"
    that the defendants had purchased and sold drugs.   See 
    Kirwan, 448 Mass. at 311
    .
    We conclude that, in their initial questioning, the
    detectives did not convey a suggestion that the defendants were
    suspects; the question could have referred to many types of
    innocent activities.   At most, it was a vague and unformed
    suspicion of some illicit activity.    In Commonwealth v.
    Callahan, 
    401 Mass. 627
    , 630 (1988), officers also asked a
    defendant "what happened," after they discovered him near a dead
    15
    body; the court concluded that he was not in custody, albeit
    that he was not free to leave.   In Commonwealth v. Shine, 
    398 Mass. 641
    , 648–649 (1986), the court concluded that a defendant
    was not in custody when he made a statement to police,
    notwithstanding the interrogating officer's uncommunicated
    intent to arrest the defendant, where the officer asked only
    "natural preliminary questions designed to determine the
    defendant's identity and what he knew about the crime."    In
    Simon, 456 Mass at 287, the court determined that a defendant
    was in custody because, inter alia, police officers began a
    conversation with the defendant by informing him that he was
    suspected of shooting the victim.   In this case, by contrast,
    the evidence does not clearly establish that the detectives told
    the defendants they were suspected of a crime.
    Although Columbus apparently suspected that Cawthron had
    purchased drugs, based on the conversation that Donovan
    overheard in the convenience store parking lot, this
    "unarticulated suspicion[] contribute[d] nothing to the
    objective circumstances of the encounter."   See 
    Groome, 435 Mass. at 212
    n.13; Commonwealth v. Gendraw, 
    55 Mass. App. Ct. 677
    , 683 (2002) ("although the officers may have believed that
    the defendant was a suspect . . . the detectives did not convey
    any such belief to the defendant").   Columbus's question to
    Cawthron, "What did you just buy?" may suggest the topic of his
    16
    preliminary investigation.   In determining whether a suspect was
    in custody at the time a statement was made, however, police
    officers' questions are relevant if they "affected how a
    reasonable person in that position would perceive his or her
    freedom to leave."   See Stansbury v. California, 
    511 U.S. 318
    ,
    325 (1994).   Columbus's question would not cause a reasonable
    person to feel that his freedom to leave had been curtailed to
    the degree associated with formal arrest.
    The judge found that a reasonable person in Flodstrom's
    situation would have believed that police suspected him of a
    crime, in part, because Columbus brought over the bottle of
    pills to show Donovan, in Flodstrom's line of sight, before, or
    during, Donovan's questioning of Flodstrom.   This factual
    finding is unsupported by the evidence introduced at the
    hearing, and, therefore, we decline to defer to it.9
    9 At the end of his cross-examination of Donovan, Cawthron's
    counsel asked Donovan if Columbus brought the pills over after
    Flodstrom had told Donovan about the exchange. Donovan first
    replied, "Yes, I believe so;" when asked if he was sure, Donovan
    said, "Yes. [Flodstrom] had stated that he had sold [Cawthron]
    pills and handed me money." When pressed about the timing,
    Donovan responded, "I don't remember exactly when it happened,
    no." On redirect examination, the prosecutor again pursued this
    line of inquiry, asking, "[Y]ou were just asked if [Columbus]
    had either informed you that he had recovered the bottle of
    pills, or he had shown that to you. And just so I'm clear, was
    that before or after [] Flodstrom had produced the six hundred
    dollars to you?" Donovan responded, "After."
    17
    In response to multiple questions from both defense counsel
    and the Commonwealth, Donovan testified that Columbus showed him
    the pill bottle after Flodstrom had answered his questions and
    produced the money from his pocket.   Donovan did give one
    equivocal response on cross-examination, but never stated that
    he was shown the pill bottle before or while Flodstrom was
    answering his initial questions or producing the money from his
    pocket.   No other evidence was introduced about the timing.
    While a motion judge may decline to credit a witness's
    testimony, the judge may not make "findings that [are]
    inconsistent with the uncontradicted testimony of the" witness,
    where "there was no evidence to support those findings."
    Commonwealth v. Knowles, 
    451 Mass. 91
    , 93 n.2 (2008).
    In concluding that Flodstrom was in custody, the judge also
    relied in part on Donovan's decision to provide Flodstrom with
    some form of Miranda warning.   "[T]he reading of the Miranda
    rights does not automatically demonstrate seizure."
    Commonwealth v. Martinez, 
    458 Mass. 684
    , 695 (2011).    This court
    has encouraged police officers to give Miranda warnings before
    "the exact moment when the warnings are constitutionally
    required."   See Commonwealth v. Raymond, 
    424 Mass. 382
    , 393 n.9
    (1997), S.C., 
    450 Mass. 729
    (2008).   We reiterate that a
    decision to give the warnings does not indicate that a defendant
    is, in fact, in custody.
    18
    c.   Tone of interviews.   On the third Groome factor, the
    judge found that the conversations between the defendants and
    the detectives "were not relaxed or conversational."   Even so,
    nothing in the record suggests that they were "aggressive,"
    "persistent," or "harsh," which would support a conclusion that
    the defendants had been subject to a custodial interrogation.
    See Commonwealth v. Coleman, 
    49 Mass. App. Ct. 150
    , 155 (2000).
    The uncontroverted testimony from the detectives was that the
    interactions with the defendants occurred in a "regular tone"
    and were "very cooperative."
    In concluding that the defendants were in custody, the
    judge relied in part on the fact that "the officers asked
    questions, making clear that they expected to receive prompt
    answers, and the [d]efendants responded to each inquiry.
    Neither defendant was ever told that they were free to walk
    away, that they could terminate their interrogation whenever
    they wished . . . or anything else to offset the inherently
    coercive nature of the situation."
    Having concluded that the location of the interrogations
    was not coercive, we do not view the other facts identified by
    the judge, that the detectives wore "police badge[s]," and "were
    armed," as creating an inherently coercive environment.     The
    detectives did not display their weapons.   In the absence of
    evidence beyond the detectives' subjective suspicions that the
    19
    defendants had committed a crime, which are irrelevant for these
    purposes, we conclude that the tone "was neither aggressive nor
    confrontational," and that questioning was appropriate fact
    finding to confirm or dispel the detectives' belief that they
    had observed a drug transaction.    See Commonwealth v. Hilton,
    
    443 Mass. 597
    , 610 (2005), S.C., 
    450 Mass. 173
    (2007).    Contrast
    
    Coleman, 49 Mass. App. Ct. at 155
    (interrogation was
    "aggressive and persistent" where "defendant's denials were
    scorned and overridden," "substance of what was said was harsh
    and intended by the questioner to be so").
    d.    Whether the defendants were free to leave.   We turn to
    the final Groome factor, whether the defendants were free to end
    the interview by asking to terminate the interview or, simply,
    by leaving.    The detectives testified that the defendants were
    not free to leave, and that they would have prevented the
    defendants from leaving if they had tried.    Further, the
    defendants were arrested at the end of the interrogations, after
    each provided statements and physical evidence of a drug
    transaction.
    While this factor weighs in favor of a conclusion that the
    defendants were in custody, that conclusion does not necessarily
    follow.   An "arrest after an incriminating statement has been
    obtained, by itself, [does not] label[] as custodial the
    interrogation that precedes the incriminating statement"
    20
    (citation omitted).    
    Bryant, 390 Mass. at 742
    n.15.    Cf.
    Commonwealth v. Lawrence, 
    404 Mass. 378
    , 386–387 (1989)
    (declining to suppress statements made to officer during search
    of home, because defendant was not in custody at time of making
    statements, but, rather, was arrested after police found
    evidence during search).    "Not all restraints on freedom of
    movement amount to custody for purposes of Miranda."      Howes v.
    Fields, 
    565 U.S. 499
    , 509 (2012).     "Determining whether an
    individual's freedom of movement was curtailed . . . is simply
    the first step in the analysis."    
    Id. We balance
    the fact that
    the defendants were not free to leave the interview, and were
    arrested at its conclusion, against the other Groome factors.         A
    single factor rarely is determinative.      See 
    Bryant, 390 Mass. at 737
    .   The United States Supreme Court has acknowledged that "few
    motorists would feel free either to disobey a directive to pull
    over or to leave the scene of a traffic stop without being told
    they might do so," but nonetheless has concluded that traffic
    stops are not custodial and Miranda warnings are not required in
    those circumstances.    See 
    Berkemer, 468 U.S. at 436
    .
    In reaching a contrary conclusion, the judge relied on
    
    Simon, 456 Mass. at 287
    , and our previous statement that "[t]he
    critical question in determining whether an individual is in
    custody is whether a reasonable person in the individual's
    position would feel free to leave."       
    Id., citing Commonwealth
    v.
    21
    Damiano, 
    422 Mass. 10
    , 13 (1996).     While this may be a critical
    factor, today we clarify that it cannot be the determinative
    factor.   Custody is "a formal arrest or restraint on freedom of
    movement of the degree associated with a formal arrest," see
    
    Morse, 427 Mass. at 123
    ; inability to leave may support a
    finding of custody, but a Terry-type stop, without more, is not
    custodial.     See 
    Howes, 565 U.S. at 509
    .   See also 
    Berkemer, 468 U.S. at 436
    .
    This case is unlike 
    Simon, 456 Mass. at 287
    .    There,
    officers began their conversation with the defendant by telling
    him that he had been identified as the person who shot the
    victim.   
    Id. at 283.
      Although the conversation took place at
    the defendant's attorney's office, the defendant was aware that
    six or seven police officers had arrived and were waiting
    outside for him.     
    Id. at 287.
      In those circumstances, the
    defendant's freedom of movement was curtailed to a degree
    associated with formal arrest, because he was not free to leave
    a building that he knew to be surrounded by police officers, and
    because he was informed that he was a suspect.      See 
    id. at 283,
    287.   Those factors are absent from this case.     Here, the
    defendants were not told that they were suspected of a crime,
    and the discussions were held one-on-one, in an open, public
    space, rather than inside a building surrounded by other
    officers.
    22
    The circumstances here are similar to those in 
    Kirwan, 448 Mass. at 312
    , where we affirmed a Superior Court judge's
    determination that a defendant was not in custody, despite the
    judge's determination that the defendant was not free to leave
    his home, where he was speaking with an officer.    In that case,
    the "interrogation was brief and in the nature of a preliminary
    investigation, and the defendant's detention was minimal."     
    Id. The defendants
    in this case likewise were subject to a minimal
    detention when officers asked them to move a few yards; the
    detectives conducted a very preliminary investigation, by asking
    what happened and what one defendant had purchased.   Each
    defendant, at that preliminary stage of the investigation, then
    offered the incriminating statements about purchasing and
    selling pills that resulted in their arrests.
    Because we conclude that the environment was noncoercive,
    as in Kirwan, the fact that the defendants were not free to
    leave does not transform the stops into custodial
    interrogations, where the other Groome factors weigh against
    custody.   See 
    Vanhouton, 424 Mass. at 332
    (defendant suspected
    of drunk driving and subjected to field sobriety tests not in
    custody, despite not being free to leave); 
    Callahan, 401 Mass. at 630
    (defendant was not in custody, despite officers asking
    him "what happened" and him not being free to leave after
    officers discovered dead body); 
    Bryant, 390 Mass. at 738
    –740
    23
    (defendant admitted to shooting victim and was likely not free
    to leave his home where he was speaking with police officers,
    but was not in custody immediately following confession when
    police officer asked him if he had anything more to say).
    In 
    DePeiza, 449 Mass. at 375
    & n.5, this court found that a
    Terry-type stop was noncustodial, even though the officers had
    seized the defendant for a frisk and the officers then asked
    him, "Do you have a gun or do you have a firearm?"    In holding
    that the environment was not police-dominated, the court
    concluded that the officers' question did not convey that they
    suspected the defendant of a crime, the tone of the interview
    was conversational, and at no point did the encounter become
    aggressive.   
    Id. at 376.
      Here, too, the interviews were
    conversational, the interaction was not aggressive, and
    Columbus's question, "What did you just buy?" did not convey to
    Cawthron that he was suspected of a crime.   We conclude that,
    absent additional factors, the defendants were not in custody
    when they made their statements to police.
    3.   Conclusion.   The order allowing the defendants' motions
    to suppress is reversed.    The matter is remanded to the Superior
    Court for further proceedings.
    So ordered.
