COMMONWEALTH vs. EMILIO DELAROSA.
Essex. January 9, 2026. โ July 21, 2026.

Homicide. Practice, Criminal, Instructions to jury, Request for
jury instructions, Capital case.
Indictments found and returned in the Superior Court
Department on December 12, 2016.
The cases were tried before Salim Rodriguez Tabit, J.

Marina Moriarty, Assistant District Attorney (Kate B.
MacDougall, Assistant District Attorney, also present) for the
Commonwealth.
DEWAR, J. A jury convicted the defendant, Emilio Delarosa,
of murder in the first degree for killing Wanda Rosa. The
defendant admitted that he strangled the victim. Seeking a
lesser conviction of voluntary manslaughter, the defendant
pursued a defense of heat of passion on reasonable provocation.
At trial, the judge denied the defendant's motion for a
2
voluntary manslaughter instruction at the close of the
Commonwealth's case but allowed the motion after the defendant
testified on his own behalf. In this direct appeal, the
defendant argues that the judge erred in initially declining to
instruct on the lesser offense, thereby in effect forcing the
defendant to testify in order to obtain the instruction.
We conclude that the trial judge did not err in denying the
defendant's motion for a voluntary instruction based on the
evidence admitted during the Commonwealth's case. And,
following review of the entire record of this case under G. L.
c. 278, ยง 33E, we decline the defendant's request that we order
a new trial or reduce the conviction to manslaughter.
Background. 1. Commonwealth's case. We recite the facts
that the jury could have found, reserving certain details for
our discussion of the issues. The Commonwealth's evidence
included an audio recording of a police interview of the
defendant, in which he described the events preceding the
killing, the killing itself, and his subsequent flight.
At the time of the killing in the early morning hours of
September 12, 2016, the defendant and the victim recently had
rekindled their on-and-off relationship of seven or eight years.
They also had a son together who, at the time of the killing,
was four years old.
3
Years earlier, the victim had obtained an abuse prevention
order against the defendant with no-contact and stay-away
provisions. In January 2012, after their son was born, the
victim obtained a modification of the order so that it still
barred abuse by the defendant but newly permitted him to contact
and visit her and the baby. In May 2012, while the modified
abuse prevention order still was in effect, the defendant
physically attacked the victim -- including, among other acts,
twisting her neck and suffocating her until she started to "see
black" and bleed from her mouth -- and, against her will, drove
her and the baby as far as New Jersey, where she obtained help
at a gasoline station.1 Following this incident, the defendant
was imprisoned for four years, for which he blamed the victim,
and the two did not communicate during this time.
After the defendant's release from prison, the defendant
and the victim resumed contact with each other; although an
abuse prevention order remained in effect, it did not contain
no-contact or stay-away provisions. By September 2016, the
defendant was staying at his sister's apartment in Lawrence but
1 When this evidence was introduced, it was accompanied by
an instruction to the jury regarding the limited purposes for
which it could be considered. Cf. Commonwealth v. Hinds, 494
Mass. 681, 690 (2024), and cases cited (evidence of defendant's
prior bad acts admissible to prove his animosity toward victims
and nature of his relationship with them).

frequently visiting the victim and their son, who lived together
in an apartment in Methuen.
On September 11, 2016, the victim was away from her
apartment attending a class. While in the victim's basement
folding laundry, the defendant discovered a letter that appeared
to have been sent to the victim by another male inmate shortly
after the defendant was incarcerated in 2012. The letter
recounted a prior comment by the victim that the letter's author
was "definitely" the father of her son, and it described the
victim as "play[ing] with [the defendant's] emotions like a yo-
yo" by telling the defendant that the defendant was the son's
father. The letter's author stated that he was going to try to
get a paternity test, but, regardless of the results, would
"always alway's [sic] have love for [the victim] for all the
things [they had] been [through]." Throughout the letter, the
author disparaged the defendant, referring to him as a "maniac"
with "a few cards missing in his poker deck," a "bad guy" who
"hit [the victim]" when she was pregnant while "thinking it was
his freaking kid," and a "Class A losser [sic]," among other
derogatory terms. The letter also evinced familiarity with
various members of the victim's family, and the author commented
that the family must be relieved that the defendant was in
prison, given their hatred for him.
5
The defendant told police that, although he wanted to
confront the victim about the letter, he initially "didn't want
to mention" it because he "knew she would . . . probably
overreact." After the victim returned home from her class, she
and the defendant went to sleep with their son in the same bed.
At around 3 A.M., the victim got up to use the bathroom.
Awakened, the defendant chose this moment to confront her.
The victim responded, "Babe, what the fuck?" The defendant then
began strangling her with his hands. The two fell to the floor,
and he continued strangling her until she was unconscious, while
their son, awakened, cried for him to stop. Neighbors through
the wall heard the victim's final words and the son's cries of
"Daddy, no."
The defendant left the letter from the inmate by the
victim's body. He then left the victim's apartment, taking
their son with him, and drove to his sister's apartment. Around
4:30 A.M. that morning, the defendant's sister found the
defendant standing in her kitchen. Based on his strange
behavior, she grew concerned and retrieved their mother from the
mother's apartment upstairs. The defendant's sister and mother
then drove to the Methuen police station to request a well-being
check on the victim, leaving the son in the care of another
relative.
6
Police officers found the victim on her bedroom floor,
covered by a blanket. She was unresponsive, and there was
bruising around her neck. Following unsuccessful efforts to
revive her, she was pronounced dead at a hospital approximately
two hours later. The medical examiner who performed the
victim's autopsy opined at trial that, based on the victim's
wounds, she was strangled to death. Deoxyribonucleic acid (DNA)
testing later confirmed that the defendant's DNA matched samples
taken from the victim's neck.
The defendant fled after his mother and sister left the
sister's apartment to go to the police station. Approximately
one year later, police located him in California, where he had
been taken into custody. The defendant then waived his rights
under Miranda v. Arizona, 384 U.S. 436 (1966), and confessed to
the killing.
2. The defense. The defendant sought to persuade the jury
to convict him of the lesser offense of voluntary manslaughter
on the theory of heat of passion on reasonable provocation. He
argued, in essence, that he reacted instinctively, overwhelmed
by anger at both the revelations in the letter he had discovered
-- that the victim had been unfaithful, and that another man had
fathered the son the defendant had believed to be his own -- and
the victim's response when he confronted her with the letter.
The defendant initially sought to present these arguments
7
without testifying himself. But after the judge ruled, for
reasons we shall discuss, that the defendant was not entitled to
a voluntary manslaughter instruction based on the evidence
admitted during the Commonwealth's case, the defendant testified
in his own defense.
The defendant's testimony elaborated in a number of
respects on his account of the events in his recorded statement
to police. He described how, prior to the victim's pregnancy
with their son, he had struggled with infertility and did not
believe he was able to have children. Although he had obtained
a paternity test showing that he was the son's father, the
testing provider had told him the results might not be
admissible in court, leaving lingering doubt in his mind about
the results' veracity.
On the night of the killing, although the defendant wanted
to speak with the victim about the letter he had found, he
decided not to confront her when she came home, because they
were having a "good conversation," and it "didn't feel . . .
appropriate" to raise the subject then. When he did confront
her in the middle of the night, she admitted that she was unsure
who was the father of her son, and she accused the defendant of
fabricating the prior paternity test results. When the
defendant suggested obtaining an official test through the
courts and then changing the son's last name to his, the victim
8
began yelling aggressively and declared that the defendant was
not the father, and the child would "never be [his] son." In
response, the defendant "snapped" and began choking her without
realizing what he was doing. He "came to" when his son held his
hand and told him to stop.
3. Prior proceedings. On December 12, 2016, a grand jury
indicted the defendant for murder. The jury trial began on
January 26, 2023, and concluded on February 2, 2023. The
Commonwealth proceeded on theories of murder committed with
deliberate premeditation and with extreme atrocity or cruelty.
Although the judge declined to instruct the jury on voluntary
manslaughter at the close of the Commonwealth's case, he
concluded at the close of all the evidence that such an
instruction was appropriate based on the new details in the
defendant's testimony, including that, just prior to the
killing, the victim accused the defendant of fabricating the
prior paternity test and then yelled aggressively that the son
was not his and never would be.
After being instructed on the two theories of murder in the
first degree, murder in the second degree, and voluntary
manslaughter on the theory of heat of passion on reasonable
provocation, the jury found the defendant guilty of murder in
the first degree committed with extreme atrocity or cruelty.
9
The judge sentenced the defendant to life in prison without the
possibility of parole. This timely appeal followed.2
Discussion. 1. Voluntary manslaughter instruction. The
defendant's principal claim on appeal is that the judge erred in
denying him a voluntary manslaughter instruction at the close of
the Commonwealth's case. Because the defendant preserved the
issue, we review the judge's denial of the instruction for
prejudicial error. See Commonwealth v. Escobar, 493 Mass. 694,
708 (2024).3
The judge was required to instruct the jury on voluntary
manslaughter at the defendant's request based on the evidence
admitted during the Commonwealth's case "if, on any view of the
evidence, regardless of [its] credibility, manslaughter may be
found" (quotation omitted). Commonwealth v. Acevedo, 446 Mass.
435, 442-443 (2006), quoting Commonwealth v. Carrion, 407 Mass.
2 The defendant also was indicted for and convicted of
violating the abuse prevention order that the victim had
obtained against the defendant, and he received a concurrent
sentence of two and one-half years for the offense. The
defendant has not presented any argument challenging this
conviction on appeal.
3 The defendant argues both that the claimed error caused
him prejudice and that it amounted to a constitutional violation
that was not harmless beyond a reasonable doubt, because the
ruling in effect compelled him to testify contrary to his right
not to do so. Concluding as we do that the judge did not err in
denying the requested instruction at the close of the
Commonwealth's case, we need not reach either argument.
10
263, 266-267 (1990). We therefore view the evidence in the
light most favorable to the defendant in determining whether
such an instruction was warranted. See Acevedo, supra at 443.
"Voluntary manslaughter is unlawful homicide arising not
from malice, but 'from the frailty of human nature,' as in a
case of 'sudden passion induced by reasonable provocation,
sudden combat, or excessive force in self-defense.'"
Commonwealth v. Bins, 465 Mass. 348, 368-369 (2013), quoting
Carrion, 407 Mass. at 267. "Reasonable provocation 'is
provocation that would have been likely to produce in an
ordinary person such a state of passion, anger, fear, fright, or
nervous excitement as would eclipse his capacity for reflection
or restraint'" (quotation omitted). Commonwealth v.
Fratantonio, 495 Mass. 522, 530 (2025), quoting Bins, supra at
369. To warrant a jury instruction for voluntary manslaughter
based on reasonable provocation, "[t]he evidence must be
sufficient to create a reasonable doubt in the minds of a
rational jury that a defendant's actions were both objectively
and subjectively reasonable." Fratantonio, supra, quoting
Commonwealth v. Groome, 435 Mass. 201, 220 (2001). In other
words, "the jury must be able to infer that a reasonable person
would have become sufficiently provoked and would not have
'cooled off' by the time of the homicide, and that in fact [the]
11
defendant was provoked and did not cool off." Fratantonio,
supra, quoting Groome, supra. See Acevedo, 446 Mass. at 443.
"In general, words alone are not sufficient provocation,"
because "a reasonable person can be expected to control the
feelings aroused" by "verbal insults and arguments, even if
obscene or hostile" (quotation and citation omitted).
Commonwealth v. Ronchi, 491 Mass. 284, 292 (2023). An exception
exists, however, for statements that "convey inflammatory
information" and "constitute a peculiarly immediate and intense
offense to [one's] sensitivities" (quotation and citation
omitted). Commonwealth v. Mercado, 452 Mass. 662, 671 (2008).
For example, at the time of the defendant's trial, "a defendant
could pursue [a reasonable provocation] defense based on
evidence of a 'sudden discovery of present spousal infidelity,'
including discovery by means of a sudden oral admission of
adultery" (citation omitted). Fratantonio, 495 Mass. at 530.4
The defendant argues that the judge was required to give a
voluntary manslaughter instruction based on the evidence
4 After the defendant's trial, in Ronchi, 491 Mass. at 295,
we held that, "[g]oing forward, we no longer will recognize that
an oral discovery of infidelity satisfies the objective element
of something that would provoke a reasonable person to kill his
or her spouse." But we did not "foreclose the possibility of
sufficient provocation caused by learning of other types of
information of a nature to cause a reasonable person to lose his
[or her] self-control" (quotation and citation omitted). Id.
12
presented during the Commonwealth's case, because the jury could
have found reasonable provocation on either of two grounds.
First, the defendant contends that his discovery of the letter
alone amounted to reasonable provocation; in inflammatory terms,
the letter revealed the victim's intimate relationship with
another man and the victim's doubts about the defendant's
paternity of his son. Moreover, the defendant contends, his
recorded statement to the police showed that he in fact was
provoked by the letter. And, although there was a gap in time
between his discovery of the letter and the killing, the
defendant argues that the provocation was so intense that a
reasonable person would not have cooled off during the
intervening period, and the defendant's statement showed that in
fact he had not cooled off. Second, the defendant alternatively
argues that, even if he had sufficient time to cool off after
discovering the letter, the victim's conduct just prior to the
killing also amounted to reasonable provocation.
We discern no error by the trial judge. With respect to
the letter itself, even assuming without deciding that a
reasonable person would have been provoked by its contents and
that the defendant in fact was provoked, under "any view of the
evidence" (citation omitted), Acevedo, 446 Mass. at 442, a
reasonable person would have cooled off from any heat of passion
induced by the letter by the time of the killing. By the
13
defendant's own account of the events in his statement to the
police, not contradicted in these respects by the Commonwealth's
other evidence, the defendant discovered the letter while
folding laundry in the victim's basement, later went to sleep in
bed beside the victim and their son, and did not confront her
with the letter until they woke in the middle of the night.
Even viewing the evidence in the light most favorable to the
defendant, following this course of events, "no reasonable
person would have remained provoked and not have 'cooled off' at
the time of the stabbing." Commonwealth v. Gonzalez, 465 Mass.
672, 687 (2013). See, e.g., id. at 686-687 (voluntary
manslaughter instruction unwarranted where, although precise
amount of time following claimed provocation was unclear,
defendant packed clothing and spent time in different room alone
before returning and stabbing victim); Commonwealth v. Smith,
460 Mass. 318, 325-326 (2011) (where defendant "engaged in
ordinary activity" after claimed provocation, later attack on
victim "was not the result of an immediate and emotional
eruption" as matter of law, despite silent record regarding
length of time between provocation and attack).5 Because the
5 The defendant contends that the judge failed to view the
evidence in the light most favorable to him with respect to the
length of time that passed between the defendant's discovery of
the letter and the killing; although the judge referred to
"hours and hours" as having passed, the defendant contends that,
based on the limited evidence regarding the timeline, the length
14
defendant's actions thus were objectively unreasonable based on
the evidence presented during the Commonwealth's case, he was
not entitled to the voluntary manslaughter instruction,
regardless of whether he in fact had cooled off by the time of
the killing. See Fratantonio, 495 Mass. at 530.
We are not persuaded to conclude otherwise by the
defendant's reliance on Commonwealth v. Andrade, 422 Mass. 236
(1996). There, the defendant confirmed his wife's infidelity,
had "a comparatively amicable discussion of their situation"
with her shortly afterwards, fell asleep, and subsequently
killed her at least seven hours after the initial confirmation.
Id. at 238, 240. Although we noted that "voluntary manslaughter
was a possible verdict, although an unlikely one," id. at 237,
the issue of whether a voluntary manslaughter instruction was
required in the circumstances was not before us; the judge had
given the instruction, id. at 238. Moreover, elsewhere in the
opinion we noted the "dearth of evidence tending to show that
the defendant had lost control of himself on the night of the
killing and acted in the heat of passion." Id. at 241. To the
extent that Andrade could be understood to suggest that a
of the intervening period was "indeterminate." Deciding the
case as we do based on the events that undisputedly transpired
during the intervening period, we need not consider the issue.
15
voluntary manslaughter instruction was required in the
circumstances presented here, we disavow the suggestion.
We also reject the defendant's argument that, even if he
had sufficient opportunity to cool off following his discovery
of the letter, the evidence in the Commonwealth's case regarding
his confrontation with the victim just prior to the killing
provided grounds for giving the requested instruction. In his
police interview, the defendant described the victim as having
"snapped" when he confronted her with the letter and asked her
if she was "really confused about who [the son's] father was,"
and the son, in his testimony, described the defendant as
becoming "louder" and "angry" in response to a statement by the
victim. The defendant also stated that he strangled the victim
out of "instinct" and "with a lot of anger" that was
"overwhelming"; that he "wasn't conscious of what [he] was
doing" but at one point asked the victim why she "ha[d] to lie
and put [him] through this"; and that "reality started kicking
in" only when his son told him to stop. The defendant argues
that a jury reasonably could infer from this evidence that the
victim's "words and actions conveyed to [the defendant] that
[she] had lied about [the son's] paternity." As the judge
correctly concluded, however, there was no evidence that the
victim conveyed new inflammatory information to him to justify
an exception from the general rule that mere words do not amount
16
to reasonable provocation. See Mercado, 452 Mass. at 671.
Although the jury reasonably could infer from the evidence that
the defendant and the victim argued over the contents of the
letter, which raised questions about the son's paternity, the
jury would have had to speculate as to any "sudden" revelation
by the victim during the argument that differed from the
information in the letter discovered earlier. Id. See Ronchi,
491 Mass. at 293 (because discovery must "comprise sudden
knowledge[,] an actual confirmation of a suspicion of infidelity
is not sufficient"). See also Gonzalez, 465 Mass. at 686
(voluntary manslaughter instruction unwarranted based on "mere
speculation" as to provocation by victim); Groome, 435 Mass. at
220 ("judge may not charge on a hypothesis not supported by the
evidence" [citation omitted]). The judge therefore did not err
in declining to instruct the jury on voluntary manslaughter
based on the evidence admitted during the Commonwealth's case.
2. G. L. c. 278, ยง 33E. We have reviewed the entire
record of the case pursuant to our duty under G. L. c. 278,
ยง 33E. We discern no basis to exercise our authority to reduce
the verdict or order a new trial.6
6 In arguing for relief under G. L. c. 278, ยง 33E, the
defendant briefly contends that the prosecutor's cross-
examination of the defendant included two improper lines of
questioning. These questions, to which the defendant did not
object, concerned (1) whether injuries visible around the
victim's eyes in a photograph taken in connection with the prior

Conclusion. The trial judge did not err in denying the
defendant's motion for a voluntary manslaughter instruction at
the close of the Commonwealth's case. Following our review of
the record under G. L. c. 278, ยง 33E, we affirm the judgments.
So ordered.
2012 incident were consistent with strangulation, and (2)
whether the victim's affidavit in support of the application for
an abuse prevention order alleged that the defendant had made
various threats to the victim. Even assuming without deciding
that these questions were improper, they did not create a
substantial likelihood of a miscarriage of justice in the
circumstances of this case.
