vs.

MATTHEW POTTER.

MEMORANDUM AND ORDER PURSUANT TO RULE 23.0

Following a jury trial in the Superior Court, the defendant

was convicted of manslaughter in violation of G. L. c. 265,

§ 13.1 On appeal, the defendant claims that the trial court

erred in denying his motion for a required finding of not guilty

because the Commonwealth failed to present sufficient evidence

to support a conviction for involuntary manslaughter. In the

alternative, the defendant argues that if the evidence is found

to be sufficient to support his conviction, that the

Commonwealth did not meet its burden to prove that the defendant

1The jury found the defendant not guilty of two counts of indecent assault and battery on a person over fourteen, in violation of G. L. c. 265, § 13H, and one count of assault, in violation of G. L. c. 265, § 13A (a). did not act in proper self-defense, and thus, the conviction

cannot stand. We affirm.

Background. We summarize the relevant facts that the jury

could have found, viewing the evidence in the light most

favorable to the Commonwealth, and reserving certain facts for

later discussion. See Commonwealth v. Latimore, 378 Mass. 671,

676-677 (1979). On January 26, 2019, Matthew Potter, the

defendant, was at the Nickerson Post of the American Legion

(Post) in Quincy with his brother, Steven Potter; Chris McCallum

(victim) and his brother William McCallum (Billy), were also at

the Post.

In the late evening, the director of the Post declared the

bar closed and told the patrons to leave. As patrons exited, a

large fight broke out; in the melee, the defendant, the victim,

and Billy were rolling around on the ground. An acquaintance

pulled Billy out of the group, then pulled the defendant up and

out of the group and "told [the defendant] to screw." The

defendant initially moved away, but then turned back to face the

door of the Post and continued to argue with Billy. The

acquaintance stood between the defendant and Billy, who

continued to yell at each other; the victim came from behind

Billy and went past the acquaintance. Seconds later, while the

victim was standing still with his hands at his sides by his

pants pockets, "his head snapped around . . . and his body

2 followed, and he just went down." When the victim fell to the

ground, the defendant was a foot or two away standing over him.

After the victim fell, the defendant backed away and left. The

victim was transported to the hospital and died from his

injuries; his cause of death was blunt force trauma to the head.

Later the same night, the defendant was stopped by a police

officer who asked how he sustained injuries to his lip and face.

The defendant stated that he "slipped and fell on ice."

The Commonwealth's theory at trial was that the defendant

caused the fatal injury by forcefully punching the victim

causing him to fall and strike his head on the pavement. The

defendant moved for a required finding of not guilty both at the

close of the Commonwealth's evidence and at the close of all of

the evidence. The judge denied both motions. As relevant to

the defendant's appeal, the jury were instructed on involuntary

manslaughter under both the theory of wanton or reckless conduct

and the theory of battery, and found the defendant guilty on

both theories. This appeal followed.

Discussion. 1. Sufficiency of the evidence of

manslaughter. "A defendant is entitled to a required finding of

not guilty only when 'the evidence is insufficient as a matter

of law to sustain a conviction on the charge.'" Commonwealth v.

Andrews, 427 Mass. 434, 440 (1998), quoting Mass. R. Crim. P.

25 (a), as amended, 420 Mass. 1502 (1995). We review "whether,

3 after viewing the evidence in the light most favorable to the

prosecution, any rational trier of fact could have found the

essential elements of the crime beyond a reasonable doubt"

(citation omitted). Latimore, 378 Mass. at 677.

The elements of manslaughter are derived from common law.

Commonwealth v. Catalina, 407 Mass. 779, 783 (1990). "A verdict

of involuntary manslaughter is warranted only where the

defendant caused an unintentional death (1) during the

commission of an act amounting to wanton or reckless conduct, or

(2) during the commission of a battery" (quotation and citation

omitted). Commonwealth v. Degro, 432 Mass. 319, 331 (2000).

The evidence at trial was sufficient to prove the defendant's

guilt under either theory.

As an initial matter, we are satisfied that despite the

absence of direct evidence that the defendant punched the victim

and caused him to fall and hit his head, causing the fatal

injury, the evidence was sufficient to prove that the defendant

did so. The jury were permitted to rely entirely on

circumstantial evidence to decide, including the defendant's

recent fistfight with the victim and Billy and the defendant's

failure to leave the area when that fight broke up, his

proximity to the victim at the time that the victim's head

snapped back and he fell to the ground, and the defendant's

unlikely explanation to the police about the injuries on this

4 face. See Commonwealth v. Cullen, 395 Mass. 225, 230 (1985)

("Inferences drawn from circumstantial evidence need not be

inescapable or necessary, so long as they are reasonable,

possible and not unwarranted because too remote" [quotation and

citation omitted]). From this evidence the jury could have

found that the defendant's blow was the cause of the victim's

fall and subsequent fatal injury.

The evidence was likewise sufficient to prove that the

death was involuntary manslaughter under either of the two

theories argued by the Commonwealth. The first theory applies

"where death is caused by wanton or reckless conduct -- that is,

'intentional conduct that create[s] a high degree of likelihood

that substantial harm will result to another person.'"

Commonwealth v. Njugana, 495 Mass. 770, 781 (2025), quoting

Commonwealth v. O'Brien, 494 Mass. 288, 297 (2024). "Wanton or

reckless conduct generally involves a [willful] act that is

undertaken in disregard of the probable harm to others that may

result." Commonwealth v. Life Care Ctrs. of Am., Inc., 456

Mass. 826, 832 (2010). "Although our cases state frequently

that [t]he essence of wanton or reckless conduct is intentional

conduct, reckless conduct does not require that the actor intend

the specific result of his or her conduct, but only that he or

she intended to do the reckless act" (quotation and citations

omitted). Id.

5 Here, the jury could have found that the defendant punched

the victim as the victim stood looking around, with his hands

down by his sides, unprepared for the blow. The jury could also

have found that the defendant hit the victim with enough force

that "[the victim's] head snapped around . . . and he just went

. . . [r]ight down like a tree," causing him to hit the pavement

so hard that he suffered multiple skull fractures. We are

satisfied that this evidence was sufficient to prove that the

punch was "undertaken in disregard of probable harm" to the

victim and "there [was] a high likelihood that such harm [would]

result," Life Care Ctrs. of Am., Inc., 456 Mass. at 832, and

that the jury could properly have concluded, as it did, that the

defendant's conduct was wanton and reckless. See Commonwealth

v. Pease, 49 Mass. App. Ct. 539, 541 (2000) (defendant's

forceful shove of victim to sidewalk, resulting in victim's

death from head injury, was sufficient to prove wanton and

reckless conduct required for conviction of involuntary

manslaughter). While the defendant may not have intended to

cause the victim's death, he did intend the punch which caused

that result. See Commonwealth v. Levesque, 436 Mass. 443, 452

(2002).

Under the second theory, involuntary manslaughter occurs

"where the defendant caused an unintentional death . . . during

the commission of a battery" (citation omitted). Commonwealth

6 v. Felix, 476 Mass. 750, 760 (2017). "[T]he battery in question

must be one that does not amount to a felony, but one that the

defendant knew or should have known endangered human life." Id.

The evidence was likewise sufficient to prove the

defendant's guilt under this theory because, as noted above, the

jury could have found that the defendant struck the victim --

thereby committing a battery against him -- while the victim was

unprepared with his hands down by his sides, and that the

defendant knew or should have known that doing so endangered the

victim's life. See Commonwealth v. Sheppard, 404 Mass. 774, 777

(1989) (punch by defendant that caused victim to fall to street

and suffer head injury, resulting in death, was sufficient to

support jury's finding of intentional battery and resulting

manslaughter conviction).2

2. Self-defense. A defendant is entitled to a jury

instruction on self-defense when the evidence, viewed in the

light most favorable to the defendant, raises

"a reasonable doubt that the defendant: (1) had reasonable grounds to believe and actually did believe that he was in imminent danger of death or serious bodily harm, from which he could save himself only by using deadly force, (2) had availed himself of all proper means to avoid physical combat before resorting to the use of deadly force, and

2 The defendant rested without presenting any evidence, so we need not consider whether the prosecution's case deteriorated after the close of its case. Cf. Commonwealth v. Wurtzberger, 104 Mass. App. Ct. 558, 565-566 (2024).

7 (3) used no more force than was reasonably necessary in the circumstances of the case."

Commonwealth v. Harrington, 379 Mass. 446, 450 (1980). Here,

the defendant raised the defense, and the judge properly

instructed the jury. The defendant argues, however, that the

evidence was insufficient to prove, beyond a reasonable doubt,

that he did not act in proper self-defense. In assessing the

defendant's sufficiency challenge, we again view the evidence in

the light most favorable to the Commonwealth to determine if the

prosecution disproved the defense, or, put another way, if the

evidence "was sufficient to persuade a rational trier of fact

that this burden was met." Commonwealth v. McAfee, 430 Mass.

483, 496 (1999).

We conclude that the evidence presented did not show that

the defendant was in imminent danger, nor did it show that he

attempted to retreat. The defendant was told to "go screw"

after being pulled from the scrum that included the victim and

Billy. Instead of retreating, and despite having no impediment

to leaving, the defendant struck the victim as the victim stood

nearby, looking around with his hands down by his sides. The

victim was not threatening or engaged in a fight. Based on

these facts, a reasonable juror could infer that the defendant

did not believe he was in imminent danger of death or bodily

harm and could conclude that the defendant did not "avail[]

8 himself of all proper means to avoid physical combat."

Harrington, 379 Mass. at 450. Moreover, the evidence that the

victim's hands were down and that he was not engaged in any

fighting at the time that he was struck by the defendant was

sufficient for a reasonable juror to conclude that in delivering

the fatal blow, the defendant used more force than was

reasonably necessary in the circumstances. Id.

Judgment affirmed.
