     Indictments found and returned in the Superior Court
Department on March 9, 2006.

     Pretrial motions to suppress evidence were heard by Janet
L. Sanders, J.; the cases were tried before Kenneth J. Fishman,
J., and a motion for a new trial, filed on August 4, 2014, was
heard by him.


     Robert F. Shaw, Jr., for the defendant.
     Pamela Alford, Assistant District Attorney (Craig F.
Kowalski, Assistant District Attorney, also present) for the
Commonwealth.


    GAZIANO, J.    A Superior Court jury found the defendant

guilty of murder in the first degree, on a theory of deliberate

premeditation, in the shooting death of Jamal Vaughn (victim) on
                                                                    2


January 9, 2006, in Quincy.   Before us is the defendant's appeal

from his convictions and from the denial of his motion for a new

trial.   He claims that his trial counsel's uninformed decision

not to introduce cell site location information (CSLI) to

contradict the testimony of a key prosecution witness

constituted ineffective assistance of counsel, and that it was

error for a motion judge to deny his pretrial motion to suppress

the testimony of the same witness because the Commonwealth had

obtained his testimony as a result of an illegal wiretap that

this court previously had ordered suppressed.   See Commonwealth

v. Long, 454 Mass. 542 (2009).

    We conclude that the defendant was not deprived of the

effective assistance of trial counsel, and that there was no

error in the motion judge's determination that the witness's

testimony was sufficiently attenuated from the suppressed

wiretap evidence to dissipate the taint of illegality.

Accordingly, we affirm the conviction and the denial of the

motion for a new trial, and decline to exercise our authority

under G. L. c. 278, § 33E, to disturb the verdict.

    1.   Facts.   We recite the facts that the jury could have

found, reserving certain facts for our analysis of the

particular issues.

    From late 2005 to early 2006, the defendant would

frequently stay with his girl friend, Janet Ojo, at her house on
                                                                     3


Franklin Street in Quincy.     About two weeks before the shooting,

the defendant and Ojo got into a dispute over money and she

ended the relationship.

       On the evening of January 9, 2006, the defendant asked

Courtney Forde to drive him to Ojo's house to pick up some

belongings that he had left behind.     Forde picked the defendant

up in his minivan.   He also brought along his friend and drug

dealing associate, Paul Brown, and a woman whom Forde had

recently met.

       When they arrived at Ojo's house, the defendant got out of

the vehicle and went inside.    Ojo was not home, but the

defendant encountered a few of her friends, including the

victim.   The defendant and the victim got into a fistfight about

some money that Ojo maintained the defendant had stolen from

her.    The fight spilled outside to the front yard.   Brown got

out of the minivan and attempted to tear off a door from a

vehicle parked in the driveway.    Now outnumbered, the victim ran

inside the house.    The defendant tried to re-enter the house and

tossed a brick through one of the windows.

       The defendant and Brown got back into the minivan and Forde

drove a short distance down the street, then stopped the vehicle

because the defendant had remembered that he had left some "IDs"

behind in a shoebox.    Forde, the defendant, and Brown walked
                                                                     4


back to the house.   The victim was outside and ran back into the

house when he saw the three approaching.

    Forde drove back to Boston.    Along the way, he dropped off

the unnamed woman in Milton.   Forde stopped at the house in the

Mattapan section of Boston where the defendant was staying at

that time, and the defendant was able to find his keys to Ojo's

house.   Forde, the defendant, and Brown returned there.    This

time, nobody was home.   The three entered using the defendant's

keys and took numerous items, some belonging to the defendant

and some belonging to Ojo, including women's clothes, food, and

electronics.   They also took two handguns stored in a shoebox, a

revolver and a "rusty" Tec-9 semiautomatic pistol.    The

defendant put the revolver "on his waist."

    The defendant then directed Forde to drive to an apartment

building on Willard Street in Quincy, where, Forde knew, the

defendant had stayed with Ojo in the past.    As they approached

the building, Forde called two of his drug customers, who lived

there.   He intended to ask one of them to open the back door so

that the defendant could enter the building.    Neither answered.

    Forde backed the minivan into a dimly-lit spot near some

trees, far from the entrance to the building.    At the same time,

the victim left the building to retrieve a package of cigarettes

from his vehicle.    The defendant and Brown got out of Forde's
                                                                     5


vehicle, walked quickly over to the victim, and shot him several

times.1

     At around midnight, a neighbor at the Willard Street

building telephoned 911 to report hearing gunshots.     Police and

emergency services responded to the scene, where they discovered

the victim with three gunshot wounds.    He was transported to a

hospital where he was pronounced dead.

     Police recovered two spent projectiles, fired from two

different weapons, from the victim's body, and seven shell

casings, all of which came from the same nine millimeter pistol.

They also found on the ground near the victim's jacket a spent

projectile that was "mostly" consistent with having been shot

from a revolver.

     After the shooting, Forde drove to back to his house in

Boston from Quincy.     Forde then went to the house of one of his

friends, where the three men unloaded all of the items taken

from Ojo's house, including a shoebox containing a rusty firearm

and its magazine.

     2.   Discussion.   a.   Ineffective assistance of counsel.

The defendant argues, as he did in his motion for a new trial,

that his trial counsel was constitutionally ineffective.     He

contends that counsel should have introduced CSLI evidence to


     1
       The Commonwealth charged Brown with the victim's murder,
and he was acquitted in a separate trial.
                                                                    6


challenge the testimony of Forde, who testified pursuant to a

plea agreement, concerning his whereabouts during a specific

period of time near the time of the shooting.    The defendant

also maintains that counsel failed to investigate, and did not

understand, the significance of the CSLI evidence.2

     In reviewing a claim of ineffective assistance in a case of

murder in the first degree, we apply the more favorable standard

of review of a substantial likelihood of a miscarriage justice,

pursuant to G. L. c. 233, § 33E.   See Commonwealth v. Vargas,

475 Mass. 338, 358 (2016).   Under this standard, "[w]e consider

whether there was an error in the course of the trial (by

defense counsel, the prosecutor, or the judge) and, if there

was, whether that error was likely to have influenced the jury's

conclusion."   Id., quoting Commonwealth v. Lessieur, 472 Mass.

317, 327, cert. denied, 136 S. Ct. 418 (2015).    Where the

defendant's ineffective assistance claim is based on a tactical

or strategic decision, we apply the more rigorous standard that,

to be ineffective, the attorney's decision must have been

"manifestly unreasonable."   Commonwealth v. Lang, 473 Mass. 1,

14 (2015).

     i.   Failure to introduce exculpatory CSLI evidence.     The

defendant argues that portions of the CSLI evidence that was not

     2
       The CSLI evidence was based on records from Forde's
cellular telephone and the cellular telephone carried by Forde's
girl friend.
                                                                     7


introduced at trial would have served to challenge, and

discredit, a portion of Forde's testimony about his actions

following the confrontation with the victim at the Franklin

Street residence, and before the return there later that

evening.    He contests the accuracy of Forde's testimony that he

and the defendant left Franklin Street, traveled to Mattapan for

a brief period of time, and then returned to Franklin Street,

without mentioning any stops along the way, particularly other

stops in Mattapan and the Dorchester section of Boston.    The

defendant points to CSLI evidence showing that Forde's telephone

was absent from Quincy for more than one hour, and traveled to

several locations in Mattapan and Dorchester during that time

frame.3    He argues that trial counsel was ineffective because he



     3
       Cell site location information (CSLI) is "a cellular
telephone service record or records that contain information
identifying the base station towers and sectors that receive
transmissions from a [cellular] telephone" (quotations and
citation omitted). Commonwealth v. Augustine, 467 Mass. 230,
231 n.1 (2014), S.C., 470 Mass. 837 and 472 Mass. 448 (2015).
"'Historical' CSLI refers to CSLI relating to and generated by
cellular telephone use that has 'already occurred at the time of
the order authorizing the disclosure of such data'" (citation
omitted). Id. These records are not usable for real-time
tracking. In general, records of the specific tower which
received a cellular telephone transmission at a given time can
be used to provide a rough geographic location of that telephone
at that time, within the transmission range of that tower. Id.
at 233. See Commonwealth v. Gonzalez, 475 Mass. 396, 412 & n.37
(2016)("data from a single cell phone tower" is not adequate to
place caller within specific range of distance from that tower;
in some circumstances, transmissions are not from tower that is
geographically closest to location of given cellular telephone).
                                                                   8


failed to introduce this independent evidence to discredit

Forde's testimony.

    The judge determined that, while Forde's credibility "was

an essential issue for the jury" because of his "indisputably

critical" role in the Commonwealth's case, the defendant failed

to establish that the decision not to use the CSLI was

manifestly unreasonable.   The judge noted that the CSLI was a

double-edged sword that both called into question Forde's

earlier timeline and placed the defendant at the scene of the

shooting.   In addition, the judge concluded that trial counsel

effectively challenged Forde's credibility through rigorous

cross-examination.

    We afford particular deference to a decision on a motion

for a new trial where the motion judge was also the trial judge,

see Commonwealth v. Forte, 469 Mass. 469, 488 (2014), and

discern no abuse of discretion in this case.   The CSLI evidence

did not materially impeach Forde's trial testimony.   Forde did

not specify how long he, the defendant, and Brown were in Boston

between the two trips to Quincy.   He testified, without

providing any time frame, that they left Franklin Street, went

to Milton to drop off the woman who had been with them, went to

the house where the defendant was staying in Mattapan where the

defendant went inside for five minutes to get his keys, from

there went to a liquor store, and then drove back to Quincy.
                                                                   9


     Forde's cellular telephone, according to the CSLI evidence,

was in Quincy at 9:48 P.M.; Mattapan and Dorchester from 10:17

through 10:45 P.M.; and again in Quincy or Braintree from

11:19 P.M. until at least 11:52 P.M..   Police received the 911

call concerning shots fired in Quincy at 11:55 P.M.   The CSLI

evidence thus contains a period of approximately twenty to

twenty-five minutes that Forde did not describe during his trial

testimony.4

     The CSLI evidence may have cast some doubt on Forde’s

testimony concerning his whereabouts in Boston during that

discrete time period.   The problem with the evidence, however,

is that it corroborated Forde's testimony that he drove the

defendant from Boston to Quincy at the time of the shooting.

Thus, it was not manifestly unreasonable for trial counsel to

decline to introduce evidence placing his client at the scene of

the crime.

     Trial counsel was able to challenge Forde's testimony in a

number of other ways, none of which carried the risk of


     4
       The defendant also argues that the CSLI evidence
demonstrates that Forde was in contact with his girl friend,
during this critical time frame and that his girl friend, who
traveled from Boston to Quincy, coordinated her activities with
Forde. The CSLI evidence did not directly contradict Forde.
Forde did not offer any testimony on the subject of telephoning
his girl friend during his trips back and forth to Quincy.
Moreover, the CSLI evidence did not contradict Forde's testimony
that he met up with his girl friend sometime later in the
evening.
                                                                  10


corroborating Forde's testimony that he and the defendant had

been in Quincy at the time of the shooting.   See generally

Commonwealth v. Grenier, 415 Mass. 680, 685-687 (1993).   Trial

counsel cross-examined Forde about his plea agreement, his

occupation as a drug dealer, a prior incident in which he had

shot at someone, his infidelity to his then girl friend, the

care he took when loading his gun to make sure that his

fingerprints were not on the bullets so that they could not be

traced, and his extensive criminal record.

     Trial counsel also rigorously cross-examined Forde on

inconsistencies between the version of events that he initially

told police and his testimony at trial.5   See Commonwealth v.

Valentin, 470 Mass. 186, 191 (2014) (counsel not ineffective in

failing to cross-examine witness concerning particular statement


     5
       Initially, Forde did not tell police that he had smoked
marijuana on the night of the shooting, but admitted on cross-
examination that he had smoked marijuana and consumed alcohol
that night.

     Forde also testified that the guns that they took from
Ojo's house were a Tec-9 pistol and a .38 revolver. On cross-
examination, Forde admitted that he initially told police that
the two guns the men found at Ojo's house were a Tec-9 pistol
and a ".357." In his closing, counsel argued that Forde had
changed his story to fit the ballistics report, a further
indication that he was lying.

     Forde testified further that he had never been to the
Franklin Street house prior to the night of the shooting. On
cross-examination, however, Forde admitted that he had told
State police that he had been to the Franklin Street house on
prior occasions before the evening of the shooting.
                                                                   11


where counsel otherwise "conducted a thorough impeachment" of

witness through cross-examination).

    In his closing argument, trial counsel pointed to a number

of reasons why the jury should not believe Forde.    He told the

jury, "You have to look at Courtney Forde's testimony in the

context of that deal . . . the deal of a lifetime . . .

[whereby] Mr. Forde goes from [a] potential sentence of life in

prison to walking away."   He reminded the jury of Forde's

testimony that when the victim walked across the parking lot at

the Willard Street building, Forde did not recognize him.     "Most

crucially, he told us, from that witness stand[,] under oath[,]

he did not recognize the man at Willard Street[.]    [H]e didn't

recognize him as the man that had been fighting with [the

defendant]."

    ii.   Failure to investigate.     The defendant argues that his

trial counsel did not investigate properly the use of CSLI

evidence, and did not understand its importance.

    The duty to investigate is one of the foundations of the

effective assistance of counsel, because counsel's strategic

decisions can be adequate only if counsel is sufficiently

informed about the available options.     See Strickland v.

Washington, 466 U.S. 668, 680 (1984) ("[T]he Sixth Amendment [to

the United States Constitution] imposes on counsel a duty to

investigate, because reasonably effective assistance must be
                                                                    12


based on professional decisions and informed legal choices can

be made only after investigation of options").    Trial counsel

must conduct a reasonable investigation into possible defenses,

even if counsel ultimately does not pursue those defenses at

trial.   See Commonwealth v. Alvarez, 433 Mass. 93, 102 (2000)

(trial counsel ineffective for failing to fully examine

defendant's mental health records, which corroborated

defendant's testimony about her own mental health history, and

therefore would have aided in establishing defense of lack of

criminal responsibility defense).    Nonetheless, "[w]hile counsel

certainly has 'a duty to make reasonable investigations,'

counsel is also afforded the opportunity to 'make a reasonable

decision that makes particular investigations unnecessary.'"

Commonwealth v. Denis, 442 Mass. 617, 629 (2004), quoting

Strickland, 466 U.S. at 691.    "[S]trategic choices made after

less than complete investigation are reasonable [only] to the

extent that reasonable professional judgments support the

limitation on investigation."    Commonwealth v. Baker, 440 Mass.

519, 529 (2003), quoting Strickland, supra at 690-691.

    Here, the motion judge concluded that defense counsel

conducted an adequate investigation of the CSLI evidence.

According to an affidavit that the judge credited, defense

counsel obtained the CSLI records and was aware that a

telecommunications expert had testified at Brown's trial.
                                                                    13


Counsel had a general understanding of that testimony, but was

unaware of the specific details.   He included the expert's name

on his list of possible witnesses, but believed that his

testimony would not be necessary to impeach Forde's credibility.

Counsel ultimately decided not to present the CSLI evidence

through the expert witness "because, at the time [he] sincerely

believed that [his] cross-examination of Courtney Forde had gone

well and that [Forde] would not and could not be believed by the

jury."

    Given this, there was no abuse of discretion in the judge's

determination that defense counsel appreciated the value of the

CSLI evidence and, as the trial progressed, continued to gauge

the usefulness of this evidence.   That the defense strategy did

not achieve an acquittal does not, in hindsight, thereby render

defense counsel's strategic decision ineffective assistance of

counsel.   See Commonwealth v. Kolenovic, 471 Mass. 664, 674-675

(2015) (no ineffective assistance where defense counsel made

strategic decision to pursue specific trial strategy, unless

decision was manifestly unreasonable); Commonwealth v. Haley,

413 Mass. 770, 777-778 (1992).

    b.     Denial of motion to suppress.   The defendant's second

claim of error is that the judge who ruled on his motion to

suppress erred in denying that motion and allowing the
                                                                  14


introduction of Forde's testimony, because it was the product of

an illegal wiretap.

    i.    Background.    On January 20, 2006, the Commonwealth

obtained a warrant authorizing the placement of a wiretap on a

booth in the visiting room at the Norfolk County house of

correction in order to monitor conversations between the

defendant and his visitors.     As a result of the wiretap

recordings, police identified another witness, Gillian Gibbs,

and obtained more information on Forde's involvement in the

shooting.

    The defendant filed a motion to suppress the intercepted

conversations, arguing that the wiretap was not authorized under

G. L. c. 272, § 99.     A Superior Court judge, who was not the

trial judge, allowed the motion.     She concluded that the wiretap

did not meet the requirements of G. L. c. 272, § 99, because the

Commonwealth failed to establish that the offense under

investigation was committed in connection with "organized

crime."   A single justice of this court allowed the

Commonwealth's application to pursue an interlocutory appeal to

this court, and we affirmed the Superior Court judge's decision.

See Long, 454 Mass. at 550, 554-558.

    After an evidentiary hearing to determine the scope of the

evidence to be suppressed, the motion judge excluded the

recording of the conversation between the defendant and Gibbs,
                                                                    15


and any testimony by Gibbs.     The judge found that Gibbs's

decision to speak with police was directly motivated by the fact

that they confronted her with the wiretap evidence.     The judge

did not, however, order that any testimony by Forde be

suppressed.     To the contrary, she concluded that Forde's

decision to testify was sufficiently attenuated from the

unlawful wiretap so as to dissipate the taint of illegality.

    The motion judge found the following.      See Commonwealth v.

Scott, 440 Mass. 642, 646 (2004).     Police arrested the defendant

on January 10, 2006.    The physical evidence, however, pointed to

two shooters:    a surveillance video recording from a nearby

store showed two distinct muzzle flashes, and projectiles

recovered from the victim's body came from two different

weapons.   One of the investigators listened to the defendant's

recorded telephone calls from the house of correction in an

effort to identify the second shooter.     In one of these

conversations, the defendant spoke to "C," who said that he was

"laying low."    The defendant told "C" to "fall back . . . way

back."   Police developed information that "C," also known as

"Casino," had been with the defendant earlier in the evening on

January 9, 2006, and had made cellular telephone calls to

individuals at the Willard Street address immediately before the

shooting, but were unable to identify "C."
                                                                     16


    Police then obtained a warrant for a wiretap of one of the

internal telephones used to communicate between visitors and

inmates at the house of correction.    This wiretap enabled police

to listen to a conversation between the defendant and Gibbs.     In

that conversation, the defendant and Gibbs mentioned "C," in a

manner such that police believed "C" was Forde.     Police met with

an assistant district attorney, who issued a summons for Gibbs

to appear before the grand jury.     Police interviewed Gibbs

before she appeared and testified.    She said that Forde had told

her that he had driven the defendant to the Willard Street

address on the evening of the shooting, where the defendant got

out and Forde "saw sparks."    Gibbs later said that she would not

have told the police about Forde's statements if they had not

told her that they had listened to her jailhouse conversation

with the defendant.   Right after Gibbs appeared before the grand

jury, police obtained a warrant to arrest Forde.     The affidavit

in support of the application for the warrant is five pages

long, and contains no mention of the wiretap.     The information

that Gibbs provided to the grand jury is mentioned in a single

paragraph.

    In March, 2006, Forde was arrested on the warrant.      He was

held without bail pending trial, and declined to speak with

police.   In August, 2006, Forde changed his mind and decided to

speak with police.    He told them about Brown's and the
                                                                  17


defendant's involvement in the events of January 9 of that year.

Forde said that he had changed his mind about testifying against

the defendant and Brown because the defendant had sent him a

number of threatening letters and Brown had broken a previous

agreement in which he was to continue selling drugs and giving

some of the money to Forde.

    In November, 2006, Forde testified before the grand jury

about the events on the evening of January 9, 2006.   Following

this testimony, the district attorney offered him a plea

agreement under which Forde was to receive a sentence of eight

months of incarceration (the amount of time he already had

served), followed by a term of probation on the lesser included

charge of accessory after the fact, and the Commonwealth agreed

to enter a nolle prosequi on the murder charge after he

testified.

    In denying the defendant's motion to suppress Forde's

testimony, the motion judge determined that, although Forde

decided to testify after the unlawful wiretap, his decision was

sufficiently attenuated from the unlawful activity so as to

dissipate the taint of illegality.   The judge credited the

testimony of a State trooper that Forde likely would have been

charged in conjunction with the shooting, regardless of the

wiretap, and therefore determined that "the evidence does not

support the conclusion that the decision to arrest Forde was
                                                                   18


solely in order to gain his cooperation."     She also credited

Forde's testimony that he chose to speak with the police, not

based on his knowledge of the wiretap, but as a result of his

belief that the defendant and Brown had "disrespected" him.

    ii.   Exclusionary rule and attenuation exception.     Under

the doctrine of the "fruit of the poisonous tree," evidence

seized as a result of an illegal wiretap, even where the

defendant was not the direct target of the wiretap, generally

may not be admitted at trial.     See Commonwealth v. Damiano, 444

Mass. 444, 453 (2005), citing Wong Sun v. United States, 371

U.S. 471, 487-488 (1963).   The primary purpose for the

suppression of evidence under the exclusionary rule is to deter

unlawful searches and seizures.     Commonwealth v. Lora, 451 Mass.

425, 438 (2008).   "The rule is calculated to prevent, not to

repair.   Its purpose is to deter -- to compel respect for the

constitutional guaranty in the only effectively available way --

by removing the incentive to disregard it."     United States v.

Calandra, 414 U.S. 338, 347 (1974), quoting Elkins v. United

States, 364 U.S. 206, 217 (1960).     The exclusionary rule also

functions to "preserve judicial integrity by disassociating the

courts from unlawful [police] conduct."     Commonwealth v. Nelson,

460 Mass. 564, 570-571 (2011).

    The attenuation doctrine provides an exception to the

exclusionary rule under which evidence obtained by police as a
                                                                   19


result of an unlawful search need not be excluded if the

connection between the illegal search and the evidence is so

attenuated as to dissipate any taint of illegality.

Commonwealth v. Fredette, 396 Mass. 455, 458-463 (1985).     The

theory of dissipation of the taint attempts to determine the

point of diminishing returns at which the detrimental

consequences of illegal police action become so attenuated that

the deterrent effect of the exclusionary rule no longer

justifies its costs.   See United States v. Ceccolini, 435 U.S.

268, 275 (1978), and cases cited; Damiano, 444 Mass. at 453-454;

Commonwealth v. Sylvia, 380 Mass. 180, 183 (1980).

    To determine whether evidence that is discovered after an

illegal search is sufficiently attenuated from that search so as

to dissipate the taint, the court considers the length of time

between the unlawful search and the discovery of the evidence

(temporal attenuation); whether any circumstances intervened

between the illegal act and the discovery of the evidence

(intervening circumstances); and how integral the unlawful

search was to the acquisition of the evidence (purpose and

flagrancy of the unlawful conduct).   Fredette, 396 Mass. at 460.

The burden is on the Commonwealth to establish that the taint

has been sufficiently attenuated.   Damiano, 444 Mass. at 454,

citing Fredette, supra at 459.
                                                                  20


    The defendant maintains that Forde's testimony should have

been suppressed because, but for the illegal wiretap, the

Commonwealth would not have had enough information to arrest

him, and therefore Forde would not have been compelled to tell

police what he knew in exchange for his release.   We do not

apply a "but for" test in determining whether to suppress

testimony obtained after an unlawful search.   Commonwealth v.

Caso, 377 Mass. 236, 240 (1979).   Commonwealth v. Suters, 90

Mass. App. Ct. 449, 458 (2016).    Instead, we consider the above-

noted three factors (temporal attenuation, intervening

circumstances, and the purpose and flagrancy of the unlawful

conduct) to determine "whether . . . the evidence . . . has been

come at by exploitation of that illegality or instead by means

sufficiently distinguishable to be purged of the primary taint"

(citation omitted).   Wong Sun, 371 U.S. at 488.   Damiano, 444

Mass. at 453.   Here, the factors support a determination that

Forde's decision to testify was sufficiently attenuated from the

illegal wiretap to dissipate any taint from the illegality.

    As to attenuation of time, in some circumstances, a lapse

of time of as little as three hours from the illegal search to

the decision to speak with police may be enough to dissipate the

taint.   See Commonwealth v. Fielding, 371 Mass. 97, 114 (1976).

See also Commonwealth v. Gallant, 381 Mass. 465, 466-467, 470

(1980) (lapse of mere minutes between defendant's unlawful
                                                                  21


arrest and decision to make statement, when considered in

conjunction with other factors, was sufficient to dissipate

taint).   In the circumstances here, however, the judge found

that Forde's decision to speak to police seven months after the

illegal wiretap, and five months after his arrest, weighed in

favor of attenuation.   See Fielding, supra.   The five-month

period between Forde's arrest and his decision to testify made

it more likely that his decision to testify was an independent,

free choice, and not a result of the unlawful wiretap or the

arrest that followed.   Id.

    As to the existence of intervening circumstances, if a

witness's decision to testify involves an affirmative choice,

that choice may be an intervening circumstance sufficient to

dissipate the taint of illegality.   Caso, 377 Mass. at 241 ("[A]

truly voluntary decision by a witness to testify should not be

overridden unless the extreme circumstances of a particular case

require the suppression of the testimony as a deterrent to . . .

the unlawful conduct which resulted in the discovery of the

witness").   See Commonwealth v. Lahti, 398 Mass. 829, 833-836

(1986), cert. denied, 481 U.S. 1017 (1987) (no attenuation where

judge found close connection between defendant's involuntary

statement and acquisition of witness testimony).

    In this case, the motion judge found that Forde's decision

to testify, as Forde himself testified, was not based on
                                                                      22


anything stemming from the illegal wiretap evidence.    Rather,

his decision was based on the conduct of his accomplices.        He

testified that he decided to speak with police because the

defendant and Brown had "disrespected" him.      See Caso, 377

Mass. at 243 (examining whether witness's decision to testify

was act of free will).

    As to the purpose and flagrancy of the illegal search, we

ask, first, whether the police performed the illegal act for the

purpose of obtaining the evidence that the defendant seeks to

suppress, and second, whether the police knew that their actions

were illegal but proceeded anyway (flagrancy).     See Lahti, 398

Mass. at 833; Commonwealth v. Parham, 390 Mass. 833, 843 (1984).

    Where police did not confront the witness with the

illegally obtained evidence in order to coerce that witness to

testify, this factor weighs in favor of allowing the testimony.

See, e.g., Commonwealth v. Estabrook, 472 Mass. 852, 860-865

(2015).   This is so even where the witness knew of the illegally

obtained evidence.   See Parham, 390 Mass. at 843-844

(defendant's confession not suppressed notwithstanding his

knowledge of codefendant's illegally-obtained confession,

because police had not confronted him with that statement).

Similarly, we have declined to suppress a defendant's statement,

made after an illegal arrest, where the police did not make the
                                                                  23


illegal arrest for the purpose of obtaining the statement.     See

Fielding, 371 Mass. at 114.

    Because the police did not conduct the illegal wiretap with

the purpose of obtaining Forde's testimony, and did not confront

Forde with the wiretapped conversations, the motion judge

properly determined that the purpose and flagrancy of the

illegal wiretap was sufficiently attenuated from Forde's

decision to testify as to dissipate the taint of illegality.

See Estabrook, 472 Mass. at 860-865; Caso, 377 Mass. at 241.    In

this light, Forde's decision to testify stands in stark contrast

to Gibbs's decision to testify, which was made as a direct

result of being confronted with the illegal wiretap evidence.

Police did not confront Forde directly or indirectly with the

illegally wiretapped conversation in order to induce him to

testify.   In short, police did not use information from the

illegal wiretap to arrest and hold Forde in the house of

correction in order to exert pressure on him to strike a deal.

    We conclude, therefore, that there was no error in the

judge's determination that the taint of the illegal wiretap was

sufficiently attenuated as to allow Forde's testimony to be

introduced at trial.
