Commonwealth v. Hood

2026-08-31

Summary

Holding. The Superior Court judge's denial of Hood's motion to vacate his guilty pleas and for a new trial is affirmed. Hood failed to establish either that withheld or newly discovered evidence from the Mulligan investigation would have materially affected his plea decision or that rejecting the plea would have been rational given the strength of the prosecution's case, and he failed to establish a nexus between alleged police misconduct in an intersecting investigation and the investigation of his own case.

Craig Hood pleaded guilty in 1995 to two counts of murder in the second degree and unlawful firearm possession in connection with the shooting deaths of Tracy Brown and Celine Kirk. In 2020, he moved to vacate his pleas, arguing that prosecutors failed to disclose exculpatory evidence from an investigation into Detective John Mulligan's murder, that newly discovered evidence cast doubt on his guilt, that his plea counsel was ineffective for not challenging a protective order limiting counsel's access to evidence, and that his pleas were involuntary. At an evidentiary hearing, the trial judge found that any undisclosed materials from the Mulligan investigation lacked meaningful connection to Hood's case, were cumulative of information counsel already possessed, or both. The judge further found that the strength of the Commonwealth's case—including Hood's detailed confession, ballistic evidence, eyewitness identification, and physical evidence—made it objectively rational for Hood to accept the plea offer rather than risk mandatory life sentences without parole.

Hood also argued that egregious police misconduct by detectives involved in the Mulligan investigation rendered his guilty plea involuntary. The court found no established link between the corrupt practices uncovered in the Mulligan investigation and the investigation into Brown and Kirk's murders, ruling that mere overlap in investigating officers and intersecting investigations did not establish that misconduct infected Hood's case. Hood's challenge to the voluntariness of his confession also failed because evidence of officer misconduct in other matters does not, without more, establish that a confession was coerced, and Hood identified no specific coercive tactics during his interrogation.

Key issues

  • Whether undisclosed or newly discovered evidence from a separate investigation into a police officer's murder constitutes material exculpatory evidence warranting vacation of guilty pleas
  • Whether police misconduct in a tangentially related investigation renders a guilty plea involuntary without evidence linking the misconduct to the defendant's specific case
  • Whether a defendant can establish a third-party culprit defense or Bowden defense based on evidence of motive alone without evidence of close temporal or operational connection
  • Whether a protective order limiting plea counsel's access to discovery constitutes ineffective assistance when counsel does not seek modification of the order

Procedural posture

Hood's 2020 motion to vacate guilty pleas and for a new trial was heard by the Superior Court, denied after an evidentiary hearing, and appealed directly to the Supreme Judicial Court, which granted review.

GEORGES, J. In June 1995, the defendant, Craig Hood,

pleaded guilty to two counts of murder in the second degree and

one count of unlawful possession of a firearm, in connection

with the shooting deaths of twenty-three year old Tracy Brown

and eighteen year old Celine Kirk.1 In July 2020, the defendant

filed a motion to vacate his guilty pleas, contending that the

pleas should be vacated because of undisclosed exculpatory

evidence, newly discovered evidence, ineffective assistance of

his plea counsel, and the involuntariness of his pleas. After

an evidentiary hearing, the motion was denied. Discerning no

error of law or abuse of discretion, we affirm.

Background. 1. The murders of Kirk and Brown. We

summarize the facts as recited by the prosecutor at the plea

hearing and reserve certain details for later discussion. See

Commonwealth v. Henry, 488 Mass. 484, 485 (2021). Where the

plea colloquy did not identify an officer by name, we rely on

the motion record only to supply that identifying context.

On September 29, 1993, Boston police officers responded to

an apartment in the Mattapan section of Boston following a 911

call from a young child. When police arrived, they were let

into the apartment by Brown's two year old son. Inside, they

1 The defendant also pleaded guilty to one count of assault and battery by means of dangerous weapon and one count of unlawful possession of a firearm in connection with the unrelated, nonfatal shooting of Glenn McLaughlin.

3

found Brown's infant daughter asleep in her crib. Police also

discovered the bodies of Brown and Kirk, who were both dead.

Brown had sustained one gunshot wound to the head and another to

her arm, while Kirk had sustained two gunshot wounds to her

head.

In the following days, Detectives Daniel Keeler and John

Brazil of the Boston police department interviewed, among other

people, Nikki Coleman, one of Kirk's friends. Coleman told them

that, on the afternoon of the murders, she spoke with Kirk on

the telephone. During that call, Coleman could hear the voice

of a man, whom Kirk identified as the defendant. Coleman was

familiar with the defendant, having known him for several

months. Coleman overhead Kirk and the defendant arguing about a

gold chain that the defendant had loaned to Kirk, but that Kirk

allegedly failed to return. In addition to describing her call

with Kirk, Coleman gave police the defendant's Brockton address

and identified him from a photograph.

Police discovered several outstanding warrants for the

defendant, including one for the nonfatal shooting of Glenn

McLaughlin in June of that year. The defendant had confronted

McLaughlin and shot him once in the leg with a .25 caliber

handgun. The bullet, which passed through McLaughlin's leg, was

recovered by police and later compared to three bullets removed

from Brown and Kirk's bodies. The Boston police department's

4

ballistics unit determined that the four bullets were fired from

the same gun.

The defendant was arrested in Brockton on the outstanding

warrants. While in custody, he asked to speak with the

detectives who arrested him. He then gave Keeler and Sergeant

Detective William Mahoney a detailed confession to the shootings

of Brown and Kirk. The confession aligned with the physical

evidence found in the apartment and included facts that only the

killer would have known. The defendant also described what he

had been wearing at the time of the shootings, including a green

jacket and black boots. The police collected those items and

sent them to the Boston police crime laboratory for testing.

Preliminary tests were positive for blood, but the amount of

blood was insufficient for blood typing.

The defendant told detectives that he argued with Kirk

about the gold chain on the night of the murders. When Kirk

refused to return the chain, she began escorting the defendant

out of the apartment. The defendant then shot Kirk in the head.

Brown fled into the bedroom where her infant daughter was

sleeping. The defendant followed and shot Brown twice. He then

returned to Kirk and shot her again before Brown's son pushed

him out of the apartment. When asked why he killed Brown, the

defendant said she was a witness who needed to be eliminated.

2. The indictments and guilty pleas. In November 1993, a

grand jury indicted the defendant on two counts of murder in the

first degree for the killings of Brown and Kirk, in violation of

G. L. c. 265, § 1; one count of assault and battery by means of

a dangerous weapon for the shooting of McLaughlin, in violation

of G. L. c. 265, § 15A; and two counts of unlawful possession of

a firearm, in violation of G. L. c. 269, § 10 (a). In June

1995, the defendant, who was represented by counsel, pleaded

guilty to two counts of murder in the second degree and to the

remaining charges. For the murder charges, he was sentenced to

two consecutive terms of life in State prison, with the

possibility of parole after thirty years. Additionally, he

received a concurrent sentence of from seven to ten years in

State prison for the assault and battery by means of a dangerous

weapon charge, and two concurrent sentences of from four to five

years in State prison for the unlawful possession charges.

3. The murder of John Mulligan. The defendant's arguments

on appeal are rooted in the investigation into the killing of

Boston police Detective John Mulligan, the details of which are

necessary context for our later discussion. The Mulligan murder

has come before this court before. In Commonwealth v. Ellis,

432 Mass. 746 (2000) (Ellis I), S.C., 475 Mass. 459 (2016)

(Ellis II), overruled in part by Commonwealth v. Britt, 465

Mass. 87, 100 (2013), we examined the investigation in detail.

6

We draw on pertinent portions of that discussion here,

supplemented by the motion judge's findings.

On September 26, 1993, three days before Kirk and Brown

were murdered, Mulligan was shot in his police vehicle outside a

Walgreens pharmacy store in the Roslindale section of Boston.

See Ellis I, 432 Mass. at 747. The investigation into

Mulligan's death intersected with the investigation into the

deaths of Kirk and Brown. The intersection stems from a police

interview with Sean Ellis, who was living at the time with Kirk

and Brown, his cousins. During that interview, Ellis placed

himself, Kirk, and a third individual, Terry Patterson, at the

same Roslindale Walgreens around the time of Mulligan's death.

Ellis was later indicted and, after two mistrials, convicted of

murder in the first degree for the killing of Mulligan. Id. at

749. Patterson was tried separately on a theory of joint

venture and likewise convicted of murder in the first degree.

See Commonwealth v. Patterson, 432 Mass. 767, 767-768, 770-771

(2000), S.C., 445 Mass. 626 (2005), overruled in part by Britt,

465 Mass. at 99-100.

Ellis filed a motion for a new trial, arguing that the

police's investigation was tainted due to newly discovered

evidence indicating that three detectives who investigated the

Mulligan murder, including Brazil, were engaged in unrelated

criminal conduct. See Ellis I, 432 Mass. at 764-765. At the

7

time of Ellis I, there was no evidence "suggesting that the

subject detectives procured false evidence in connection with

the investigation of [Ellis]" or that Mulligan was in any way

involved in the criminal scheme. Id. at 765. Accordingly, this

court affirmed Ellis's convictions and the order denying his

motion for a new trial. Id. at 765-766.

In 2013, Ellis filed a second motion for a new trial based

on newly discovered evidence tending to show that Mulligan

participated in "crimes of police corruption" with the

detectives who investigated his murder, and other information

that "provided . . . the police [with] possible third-party

culprits." Ellis II, 475 Mass. at 460. The motion was granted

because six categories of newly discovered evidence established

that the police did not vigorously pursue alternative leads and,

coupled with the detectives' conflict of interest in

investigating Mulligan's murder, provided a strong defense under

Commonwealth v. Bowden, 379 Mass. 472, 485-486 (1980). See

Ellis II, supra at 470.

We rejected the Commonwealth's contention that the newly

discovered evidence added "nothing material" to what Ellis

presented in his first motion for a new trial, reasoning that

"[t]he complicity of [Mulligan] in the detectives' malfeasance

fundamentally changes the significance of the detectives'

corruption" because it provided a "powerful incentive to prevent

8

a prolonged or comprehensive investigation" that might reveal

their own wrongdoing. Ellis II, 475 Mass. at 474-476.

Concluding that there was no abuse of discretion in granting

Ellis's second motion for a new trial, we affirmed. Id. at 481.

4. Motion to withdraw guilty pleas. Over the past several

decades, the defendant has filed multiple motions to vacate his

guilty pleas and for a new trial.2 In July 2020, the defendant

filed the motion for a new trial that gives rise to this appeal.

He sought to withdraw his guilty pleas on four grounds: the

Commonwealth failed to disclose exculpatory evidence relevant to

a possible third-party culprit defense, newly discovered

evidence cast doubt on his guilt, his plea counsel was

ineffective for failing to challenge a pretrial protective

order, and his pleas were not voluntary. The evidence on which

the defendant relied fell generally into two categories. The

first consisted of materials from the Mulligan investigation,

which were subject to a protective order that barred plea

2 The first motion, filed pro se, was withdrawn without prejudice. The second motion, also filed pro se, was denied without an evidentiary hearing by the same Superior Court judge who accepted the defendant's plea. The Appeals Court affirmed the denial in an unpublished decision. Commonwealth v. Hood, 56 Mass. App. Ct. 1106 (2002). The third motion, for which the defendant was represented by counsel, was denied by the same Superior Court judge who accepted his plea and denied his prior motion. The Appeals Court again affirmed in an unpublished decision. Commonwealth v. Hood, 87 Mass. App. Ct. 1105 (2015).

9

counsel from sharing them with the defendant. The second

consisted of evidence of police misconduct in the Ellis matter.

The defendant filed two affidavits in support of the

motion. In his first affidavit, he averred that (1) plea

counsel told him that he had "no chance at trial" in light of

his confession; (2) plea counsel sought discovery related to the

Ellis and Patterson matters, but could not discuss or share it

with the defendant; (3) the defendant never considered any of

the information that "may have been in" the Ellis and Patterson

matters; and (4) had the defendant known about this information,

he would not have pleaded guilty.

In his second affidavit, the defendant averred that had he

known about Mulligan's misconduct and that of the investigating

detectives, some of whom were involved in the investigation of

the Kirk and Brown murders, he would not have pleaded guilty.

He further averred that his decision to plead guilty was based

on several conversations he had with plea counsel, having

weighed the Commonwealth's evidence, and plea counsel's opinion

that the defendant's confession weighed heavily against a thirdparty culprit defense. Finally, he averred that he did not know

that his plea counsel was prevented from sharing evidence from

the Ellis and Patterson matters with him and, had he known this,

he would not have pleaded guilty.

10

An evidentiary hearing was held by a different Superior

Court judge (motion judge) from the one who accepted the

defendant's guilty pleas.3 The evidentiary hearing was limited

to two issues: the alleged failure to disclose exculpatory

material from the Mulligan investigation in violation of Brady

v. Maryland, 373 U.S. 83, 87 (1963); and the defendant's claim

of ineffective assistance of counsel. The defendant's plea

counsel and the prosecutor were the only witnesses to testify.

a. Factual findings. Based on the testimony and exhibits

introduced at the evidentiary hearing, the motion judge found

the following facts.

Between January 1994 and May 1995, the prosecutor sent plea

counsel at least twenty-one transmittal letters detailing

discovery material provided to the defendant. Based on the

prosecutor's credited testimony, the motion judge found that the

prosecutor's general practice was to review discovery packages

to ensure they included everything that was described in the

accompanying transmittal letter, and that the prosecutor

followed that practice in the defendant's case. The motion

judge further found that the defendant received the discovery

materials referenced in those twenty-one letters because she

credited plea counsel's testimony that he would have notified

3 The plea judge had since retired.

11

the prosecutor if he had not received something that was

identified in a transmittal letter.

Because plea counsel was aware that Kirk was Ellis's cousin

and that she was alleged to have been with Ellis the night of

Mulligan's murder, plea counsel sought discovery from the

Mulligan investigation concerning Ellis and Patterson to support

a third-party culprit defense that whoever killed Mulligan also

killed Brown and Kirk. Between January and July 1994, plea

counsel made various requests for discovery concerning the

Mulligan investigation. He particularly sought any information

that placed Kirk at the scene of Mulligan's murder, believing

such information would help demonstrate a motive for whoever

shot Mulligan to kill Kirk.

Ellis's counsel opposed the production of discovery prior

to the conclusion of Ellis's trial, raising concerns that the

material produced would be made public and deny Ellis a fair

trial. After Ellis's second mistrial, a Superior Court judge

(who was neither the plea judge nor the motion judge) ordered

that the material be provided to plea counsel and his associate

subject to a protective order barring them from discussing the

material with or providing the material to anyone else,

including the defendant. The subsequent discovery, detailed in

an eleven-page discovery letter, was provided to plea counsel in

April 1995, over one month before the defendant pleaded guilty.

12

Consistent with the protective order, plea counsel did not

discuss the produced material with the defendant prior to his

plea. At the evidentiary hearing, plea counsel could not recall

any specific material that he believed he "should" have

discussed with the defendant. He testified, however, that if he

had received such material, he would have sought relief from the

protective order. He did not do so. The motion judge therefore

inferred that plea counsel did not view anything in the Mulligan

investigation materials as necessary to discuss with the

defendant before the guilty pleas.

The motion judge found that plea counsel had received most

of the documents the defendant claimed had not been produced.

The motion judge did not determine whether any particular

document had been withheld from the defendant. Instead, the

motion judge assumed that certain materials had not been

produced and considered whether their absence mattered.

Those materials consisted of (1) two Federal Bureau of

Investigation (FBI) reports describing information provided by a

confidential informant, who claimed that Ellis admitted to

assisting in Mulligan's murder; (2) two police reports that

recounted statements made by Raven James -- an associate of

Ellis -- that Ellis, who had access to a .25 caliber handgun

before the Mulligan murder, "smiled and then looked at

Patterson" when James asked who had killed Mulligan; (3) two

13

recorded interviews of Evoney Chung, who was in the Walgreens

parking lot around the time of Mulligan's death and saw two

Black males in the parking lot; and (4) various telephone

hotline tips related to the murders of Kirk and Brown, including

a tip from their neighbor, Ada Jackson, who reported seeing a

person leaving Kirk and Brown's apartment on the day of the

murders,4 and another from a tipster who allegedly overheard two

school children on the subway say that a boyfriend had killed

the victims.

b. Denial of motion to withdraw guilty pleas. After

discrediting the defendant's "self-serving" averments that he

would not have pleaded guilty had he known of the Mulligan

investigation material or the evidence of police misconduct from

Ellis II, the motion judge concluded that this information would

not have materially affected the defendant's decision to plead

guilty. The motion judge reasoned that the material was either

cumulative of other information already known by the defendant,

did not significantly add to the "wealth" of information the

defendant already possessed, or was unconnected to the

investigation of Kirk and Brown's killings. For many of the

4 In her later statement to the police, Jackson described the person she saw as a "[B]lack male wearing a green jacket." The record reflects that the defendant is Black.

14

same reasons, the motion judge rejected the defendant's argument

that his pleas were involuntary.

The motion judge also concluded that rejecting the plea

offers would not have been rational in light of the

Commonwealth's strong case. That case included the defendant's

detailed confession, ballistic evidence linking the firearm used

to shoot McLaughlin to the firearm used to shoot Kirk and Brown,

and evidence placing the defendant at the scene at around the

time of the murders. The judge also considered the benefit the

defendant received from the pleas. By pleading guilty to murder

in the second degree, he avoided mandatory sentences of life

without the possibility of parole for murder in the first

degree.

For those reasons, the motion judge was not persuaded that

justice may not have been done and denied the defendant's

motion. The defendant appealed, and we allowed his application

for direct appellate review.

Discussion. A motion to vacate a guilty plea is treated as

a motion for a new trial pursuant to Mass. R. Crim. P. 30 (b),

as appearing in 435 Mass. 1501 (2001), and may be granted "any

time it appears that justice may not have been done."

Commonwealth v. Scott, 467 Mass. 336, 344 (2014). "We review

. . . to determine whether the judge abused [his or her]

discretion or committed a significant error of law" (citation

15

omitted). Henry, 488 Mass. at 490. Where, as here, an

evidentiary hearing has been held, "we accept the [judge's]

findings where they are supported by substantial evidence in the

record, and we defer to the judge's assessment of the

credibility of witnesses" (quotations and citation omitted).

Commonwealth v. Dew, 492 Mass. 254, 260–261 (2023). "However,

we make an independent determination as to the correctness of

the judge's application of constitutional principles to the

facts as found" (quotation and citation omitted). Id. at 261.

The defendant's claims arise against a troubling historical

backdrop. The investigation into Mulligan's murder was later

shown to have been compromised by serious police corruption, and

that investigation intersected in important respects with the

investigation into the murders of Kirk and Brown. That

backdrop, however, does not relieve the defendant of his burden

to connect the undisclosed or later-discovered information to

his own case and to his own decision to plead guilty. After an

evidentiary hearing, the motion judge concluded that the

defendant failed to make that showing. The record supports that

conclusion.

1. Exculpatory and newly discovered evidence, protective

order, and ineffective assistance claims. The defendant first

raises several claims that turn on what he did not know about

the Mulligan investigation before entering his guilty pleas. He

16

argues that the Mulligan investigation material constituted

withheld exculpatory evidence or newly discovered evidence. He

also argues that the judge who entered the protective order

abused her discretion in doing so, particularly where the order

precluded plea counsel from sharing that material with him.5

Finally, he claims that plea counsel was constitutionally

ineffective for failing to object to the protective order,

failing to seek modification of the order once plea negotiations

began, and failing to review all the Mulligan investigation

material or pursue leads from that material before advising him

to plead guilty.

These claims are doctrinally distinct, but they all rest on

the same showing of prejudice or materiality. See Henry, 488

Mass. at 495, citing Scott, 467 Mass. at 360-361 (in context of

motion to withdraw guilty plea, standard for newly discovered

and withheld exculpatory evidence "borrow[s] from our

5 To the extent the defendant argues that the protective order itself violated his due process rights, apart from his other claims, that argument is waived. Such a challenge to the protective order could have been -- but was not -- raised in the defendant's first motion for a new trial. See Mass. R. Crim. P. 30 (c) (2), 378 Mass. 900 (1979). Our review is therefore limited to whether the protective order created a substantial risk of a miscarriage of justice. See Commonwealth v. Randolph, 438 Mass. 290, 294 (2002). For essentially the same reasons that the defendant failed to establish prejudice on his other claims, the protective order did not create a substantial risk of a miscarriage of justice.

17

jurisprudence on claims that the ineffective assistance of

counsel induced a guilty plea"); Commonwealth v. Clarke, 460

Mass. 30, 47 (2011), abrogated in part by Chaidez v. United

States, 568 U.S. 342 (2013) (outlining prejudice for ineffective

assistance of counsel in context of guilty plea); Commonwealth

v. Holliday, 450 Mass. 794, 805, cert. denied, 555 U.S. 947

(2008) (challenge to protective order requires showing of

prejudice).6 Specifically, the defendant must show that there is

a reasonable probability that he would not have pleaded guilty

had he known of the Mulligan investigation material, and that

rejecting the plea offer would have been rational under the

circumstances.7 See Commonwealth v. Lastowski, 478 Mass. 572,

577 (2018); Scott, supra at 361-362. The question is not

whether the information would have had some arguable value. The

question is whether it "would have materially influenced [the

defendant's] decision to plead guilty." Scott, supra at 360.

6 The defendant's protective order argument substantially overlaps with his Brady violation argument. Cf. United States v. Simels, 636 Fed. Appx. 13, 15 (2d Cir. 2015) (analyzing defendant's argument that "because the government used the protective order to withhold what he asserts is exculpatory information, the government violated his due process rights under Brady"). In the circumstances of this case, we therefore analyze prejudice on those claims together.

7 As in prior cases, we need not decide whether a defendant who enters a voluntary and intelligent plea thereby "waive[s] the right to contest the claims of newly discovered evidence or prosecutorial nondisclosure." Henry, 488 Mass. at 496 n.6.

18

The defendant claims that the information from the Mulligan

investigation would have been material because it provides

additional evidence that Ellis killed Mulligan, which in turn

bolsters the theory that Ellis had a motive to kill Kirk. We

are not convinced. Motive may be important, but motive alone

does not make a third-party culprit theory materially stronger

for plea-withdrawal purposes. Cf. Commonwealth v. Andrade, 488

Mass. 522, 533 (2021), citing Commonwealth v. Scott, 470 Mass.

320, 328 (2014). Our case law requires a defendant to show that

the third party's acts are "so closely connected in point of

time and method of operation" that it raises doubt as to the

defendant's identification as the culprit (citation omitted).

Andrade, supra at 532. Similar principles apply to a Bowden

defense based on the police's failure to investigate a thirdparty culprit. See Commonwealth v. Bright, 463 Mass. 421, 440–

441 (2012) (for Bowden defense, "mere fact that" others might

have had "motive to murder the victim was of minimal probative

value absent other information that potentially linked [such

persons] to the crime" [quotation and citation omitted]).

The Mulligan investigation information did not add any

material evidence connecting Ellis, Patterson, or another third

party to the killings of Kirk and Brown. For example, the FBI

reports addressed Ellis's alleged role in Mulligan's murder, not

the Kirk and Brown killings. Likewise, the Chung interviews

19

bore on who was at the Walgreens the night Mulligan was shot,

not who killed Kirk or Brown three days later. At best, the

James reports suggested that Ellis had access to a .25 caliber

handgun, the same caliber as the firearm used to kill Kirk and

Brown. The motion judge addressed that point but concluded that

it did not materially change the plea calculus. See Andrade,

488 Mass. at 533-534 (evidence that other individuals possessed

same caliber of ammunition as that used to kill victim was

inadequate to support third-party culprit defense).

Additionally, although one of the hotline tips implicates a

boyfriend in the killings and therefore provides a possible

third-party culprit other than Ellis, it is speculative. See

Commonwealth v. Acevedo, 492 Mass. 381, 390 (2023) (evidence

proffered to mount third-party culprit defense "cannot be too

remote or speculative" [citation omitted]). Without more, as

the motion judge concluded, the Mulligan investigation material

did not "significantly increase[] the strength or viability of

any [of] Hood's defenses."

In addition to the lack of connection, the Mulligan

investigation material also was cumulative in important

respects. Cf. Commonwealth v. Lykus, 451 Mass. 310, 326 (2008)

("Newly discovered evidence that is merely cumulative of

evidence admitted at the trial will carry little weight");

Commonwealth v. Tucceri, 412 Mass. 401, 414 (1992) ("If the

20

undisclosed evidence is cumulative, . . . the failure to

disclose that evidence does not warrant the granting of a new

trial"). For example, plea counsel already possessed Jackson's

statement to police describing a Black male wearing a green

jacket leaving Kirk and Brown's apartment, and another witness's

statement implicating a boyfriend as the shooter. More

generally, before the defendant pleaded guilty, plea counsel

already knew the core facts forming the basis of the defense

that Kirk had been killed because of what she knew about the

Mulligan murder. This included facts tending to show Kirk's

alleged connection to Ellis, as well as Ellis's and Patterson's

alleged connections to the Mulligan murder.

In sum, with the evidence in the Mulligan investigation

material lacking connection to the victims' murders, being

cumulative, or both, the motion judge had adequate grounds to

conclude that the defendant failed to establish a reasonable

probability that he would not have pleaded guilty. While the

defendant asserts, without explanation, that the material would

have led him to reject the plea, the judge was not required to

accept that assertion. See Commonwealth v. Mosso, 496 Mass.

768, 780 (2025) ("Proof of prejudice cannot be based on mere

conjecture or speculation as to outcome" [quotation and citation

omitted]).

21

The record also supports the motion judge's determination

that the defendant failed to show that rejecting the guilty

pleas would have been rational under the circumstances. A

defendant may make that showing by demonstrating that he had an

"available, substantial ground of defence." Commonwealth v.

Saferian, 366 Mass. 89, 96 (1974). The defendant made no such

showing here.

The Commonwealth's case was strong. See Commonwealth v.

Lavrinenko, 473 Mass. 42, 59 n.20 (2015) (strength of

prosecution's case may be considered in assessing prejudice).

Coleman identified the defendant as the man who had been

speaking with Kirk in her apartment about the gold chain,

placing him inside the apartment on the day of the murders.

Jackson saw a Black male wearing a green jacket leaving Kirk and

Brown's apartment around the time of the murders. In his

confession, the defendant told police that he had been wearing a

green coat when he committed the murders. Police later

recovered a green coat with blood on it from the defendant's

girlfriend's home. Ballistics evidence tied the firearm used in

the murders to the firearm used to shoot McLaughlin, who

identified the defendant in a photographic array. Most

significantly, the defendant gave a detailed confession to the

killings.

22

Against that evidence, the defendant has not identified a

substantial defense that would have made it rational to reject

pleas that made the defendant eligible for parole, where he

otherwise faced the risk of mandatory life sentences without the

possibility of parole. See Henry, 488 Mass. at 493 (discussing

severity of sentence avoided by guilty plea). Cf. Commonwealth

v. Price, 106 Mass. App. Ct. 376, 379 (2025) (defendant's

knowledge "that he had the ability to avoid a mandatory life

sentence without parole if he accepted the plea deal" was

relevant to voluntariness analysis).

For these reasons, the motion judge did not err in

concluding that the defendant failed to prove prejudice or

materiality arising from the alleged nondisclosure, the laterdiscovered evidence, the protective order, or plea counsel's

handling of that order.

2. Egregious police misconduct. The defendant next argues

that his pleas should be vacated because they were rendered

involuntary by egregious police misconduct. Specifically, he

points to the police misconduct detailed in Ellis II and argues

that because many of the same police officers and detectives --including Keeler and Brazil -- were involved with the

investigations of the murders of Mulligan, Brown, and Kirk, his

guilty pleas should be vacated.

23

"Due process requires that a plea of guilty be accepted

only where the contemporaneous record contains an affirmative

showing that the defendant's plea was intelligently and

voluntarily made" (quotation and citation omitted). Scott, 467

Mass. at 345. "A plea may be defective . . . where it has been

involuntarily induced by government misconduct that since has

been discovered" (quotation and citation omitted). Commonwealth

v. Ruffin, 475 Mass. 1003, 1003 (2016). We previously "adopted

a two-pronged test to determine when government misconduct is so

egregious that it renders a guilty plea involuntary, and thus in

violation of a defendant's rights to due process." Commonwealth

v. Hallinan, 491 Mass. 730, 744 (2023). To withdraw a guilty

plea in these circumstances, the defendant must show that "(1)

egregious government misconduct took place in connection with

the defendant's case and preceded the entry of the guilty plea;

and (2) the misconduct was material to the defendant's decision

to plead guilty." Commonwealth v. Claudio, 484 Mass. 203, 206

(2020).

A defendant claiming egregious government misconduct must

show that the misconduct "preceded the entry of his or her

guilty plea," was "undertaken by government agents," and

"occurred in the defendant's case." Hallinan, 491 Mass. at 745.

The last requirement is critical here. It requires "a nexus

between the government misconduct and the defendant's own case."

24

Ruffin, 475 Mass. at 1004. We agree with the motion judge that

the defendant did not make that showing.

The additional misconduct evidence examined in Ellis II

changed the significance of police corruption in the

investigation of Mulligan's murder. It did not establish,

however, that every intersecting investigation was infected. In

Ellis I, 432 Mass. at 764-765, although Ellis had presented

evidence of corrupt practices by detectives involved in his

investigation, he was not entitled to relief in the absence of

evidence suggesting that the detectives engaged in misconduct

"in connection with the investigation of this defendant"

(emphasis added). The same principle controls here.

The defendant failed to establish a link between the

alleged police corruption and the investigation of the murders

of Brown and Kirk. Ellis II involved corrupt officers who had

specific incentive to short circuit the investigation into

Mulligan's murder because Mulligan participated in the same

criminal misconduct they sought to conceal. No comparable

evidence exists here. There is no evidence that Brown or Kirk

were involved in police corruption with Mulligan or with any of

the corrupt officers.

The defendant argues that, if the Mulligan investigation

was "poisoned" by police corruption, then the Brown and Kirk

investigation was necessarily poisoned as well because the

25

investigations "were one in the same and to any extent they were

not, one informed the other." That premise is too broad. The

investigations crossed in important respects, and those

intersections gave plea counsel a basis to pursue discovery for

purposes of a third-party culprit defense. But the nexus

inquiry asks whether misconduct infected the investigation of

this defendant, not whether some of the same detectives worked

both files or the investigations shared witnesses and leads.

See Ruffin, 475 Mass. at 1004 (defendant must "show a nexus

between the government misconduct and the defendant's own case"

[emphasis added]). Corruption in one investigation does not

become corruption in another merely because the investigations

intersected. See Ellis I, 432 Mass. at 765, citing Commonwealth

v. Campiti, 41 Mass. App. Ct. 43, 62–66 (1996) (no error to deny

motion for new trial based on evidence of unrelated police

misconduct).

At most, the defendant speculates that exculpatory evidence

could have been "overlooked" because the Mulligan investigation

was "rushed, biased, or inadequate." That is not enough to

establish a nexus between the alleged misconduct and the

defendant's case. Cf. Commonwealth v. Cotto, 471 Mass. 97, 113

(2015) ("The defendant has offered no supporting evidence to

substantiate this claim, and, in our view, it is wholly

speculative"); Commonwealth v. Nelson, 90 Mass. App. Ct. 594,

26

596 (2016) ("it is not enough simply to show that problems

occurred . . . , however egregious they were; [the defendant]

needed to demonstrate a connection between those problems and

his case").8

3. Voluntariness of defendant's confession. Finally, the

defendant challenges the voluntariness of his confession. He

argues that the corrupt police officers coerced his confession

and that, because the confession influenced his decision to

plead guilty, he should be allowed to withdraw his guilty pleas.

We disagree.

"A voluntary statement is one that is the product of a

rational intellect and a free will, and not induced by physical

or psychological coercion" (quotations and citation omitted).

Commonwealth v. Williams, 486 Mass. 646, 659 (2021). The

defendant bears the initial burden of "produc[ing] evidence

8 Notwithstanding the lack of any nexus, the defendant argues that he should be entitled to a conclusive presumption that egregious police misconduct occurred in his case. We disagree. In Scott, 467 Mass. at 352, we established a conclusive presumption of egregious government misconduct as a global remedy for defendants affected by a State police chemist's misconduct because, under the circumstances there, "it would have been impossible for the defendant[s] to show the requisite nexus between the government misconduct and [their] conviction[s]." Hallinan, 491 Mass. at 747. The same concerns are not present here. The defendant has not argued that it is impossible for him to establish a nexus between the alleged misconduct and his guilty pleas. Nor does the record support such an assertion.

27

tending to show that his statement was involuntary; if he

satisfies this burden, the Commonwealth is required to prove

beyond a reasonable doubt that the statement was voluntarily

made" (citation omitted). Id. at 659–660. See Commonwealth v.

Hart, 493 Mass. 130, 135 (2023), S.C., 497 Mass. 1 (2025) ("A

statement is presumed voluntary until a defendant produces any

evidence showing otherwise"). Although the defendant raises

several challenges to his confession, we focus on his principal

contention that the misconduct evidence of Keeler and Brazil

shows that his confession was "poisoned."9

9 The Commonwealth notes that, in an earlier motion to withdraw his pleas, the defendant argued that plea counsel was ineffective for allowing him to plead guilty without first moving to suppress his confession as involuntary. The motion judge also recognized that the defendant previously had challenged the confession and concluded that his current arguments were waived because "[a] defendant is not entitled to . . . rais[e] new, slightly different bases for the arguments already raised and rejected."

The record shows that the defendant previously raised many of the same arguments regarding the voluntariness of his confession. The parties do not brief whether direct estoppel bars him from raising those arguments again. See generally Commonwealth v. Rodriguez, 443 Mass. 707, 710 (2005). Even assuming direct estoppel does not apply, the defendant's arguments do not raise a substantial risk of a miscarriage of justice. See Randolph, 438 Mass. at 293–294. Nor do they warrant any further discussion. See Commonwealth v. Sosa, 493 Mass. 104, 124 n.12 (2023), cert. denied, 145 S. Ct. 306 (2024). Many are unsupported by citation to legal authority and therefore do not rise to the level of appellate argument. See Commonwealth v. Cassidy, 470 Mass. 201, 209 n.9 (2014).

28

Evidence that an officer engaged in misconduct in other

matters may provide impeachment material. See Matter of a Grand

Jury Investigation, 485 Mass. 641, 652 (2020). It does not,

without more, establish that a defendant's statement in a

separate case was involuntary. The defendant identifies no

specific act by Keeler, Mahoney, or Brazil that would render his

confession suspect, such as "coercive tactics during the

interrogation." Commonwealth v. Estabrook, 496 Mass. 467, 477

(2025).10 See Commonwealth v. Medina, 485 Mass. 296, 307 (2020)

("There is no indication that police officers employed coercion

or deception to elicit any of his statements"). Instead, he

argues that Keeler's and Brazil's involvement alone tainted the

confession because they engaged in unrelated misconduct. Our

law requires more. Cf. Ellis I, 432 Mass. at 765, citing

Campiti, 41 Mass. App. Ct. at 62–66 (no error to deny motion for

new trial based on evidence of unrelated police misconduct).

10The defendant's argument that his confession was involuntary because Keeler and Mahoney first questioned him during an unrecorded portion of his interrogation rests on speculation. He identifies no conduct by either officer during that unrecorded questioning suggesting that his statements were not "the product of a rational intellect and a free will" (quotations and citation omitted). Commonwealth v. Woodbine, 461 Mass. 720, 729 (2012). See Commonwealth v. DiGiambattista, 442 Mass. 423, 448-449 (2004) (mandating instruction cautioning jury about reliability of unrecorded statements but declining to require recording).

29

Additionally, the content of the confession does not

support the defendant's claim. The defendant described the

sequence of events, his clothing, and details about the crime

scene that only the killer would have known, all of which the

police independently corroborated. Those details support the

motion judge's conclusion that the confession was reliable and

not the product of coercion.

Order denying motion to

vacate guilty pleas and for

a new trial affirmed.
