MEMORANDUM AND ORDER PURSUANT TO RULE 23.0
Following a jury trial in the Superior Court, the defendant
was convicted of two counts of rape of a child with force and
two counts of aggravated rape of a child. This case presents a
classic credibility contest between the victim and the
defendant. The victim was the defendant's daughter, who was a
young teenager at the time the offenses were committed. The
defendant, who testified in her own defense, denied all the
allegations, contending that the victim was not credible.
On appeal, the defendant contends that the judge erred in
admitting prior bad act evidence.1 Mindful that we are reviewing
1She also claims that her trial counsel's performance was deficient in several respects. As a result of our disposition, most of this evidence to determine whether any error created a
substantial risk of a miscarriage of justice,2 we conclude that
this case presents the rare circumstance in which prior bad act
evidence may have overwhelmed the proceedings; the record lacks
careful and reasoned judicial scrutiny of each act, and the jury
were not provided with contemporaneous limiting instructions.
Accordingly, we are constrained to vacate the convictions.
Background. 1. Facts. We summarize the facts the jury
could have found reserving certain details for our discussion of
the issues. The victim and her twin brother grew up in a
"tumultuous" household after their parents separated when they
were about two years old. When the victim was in either the
sixth or seventh grade, she spoke with the defendant about her
sexual orientation. The defendant dismissed the victim's
thoughts that she might be a lesbian, contending that the victim
was "just confused" and "might not be ready for a man yet." The
defendant told the victim that "she was going to try and help
[her]," brought her into the bathroom, "had [the victim] remove

2 We note there was an objection to the admission of three acts, and therefore we review those for prejudicial error. See Commonwealth v. Crayton, 470 Mass. 228, 252 (2014). Our conclusion is the same as to these acts, and we would reach the same result regardless of the standard of review applied.
2 [her] pants and underwear," and inserted a tampon with the
plastic applicator into the victim's vagina "repeatedly." She
"didn't stop even when [the victim] was crying out, telling her
to stop and to not do that." The victim "was in a lot of pain"
and felt "agony between [her] legs." The defendant told the
victim that "[she] was tight" and only stopped assaulting her
once the victim "started bleeding down there."
At the end of their freshman year of high school, the
victim's brother moved out of the defendant's home because of
his contentious relationship with the defendant. The victim
continued to live with the defendant throughout that summer.
The defendant explained to the victim's friends that the brother
moved out because "[he] was the abusive one and . . . she was
afraid of him." The victim disputed this account and told her
friends that it was not true. When the defendant learned what
the victim said from the friends' parents, she became "really
upset at [the victim]" and confronted her about it. She told
the victim "that [her brother] was going to abuse [her] and try
and rape [her]." When they arrived home, the defendant brought
the victim to the bathroom, had her remove her pants and
underwear, and "put her fingers in [the victim's] vagina." The
victim testified that this assault prompted her to leave the
defendant's home and move in with her father, stepmother, and
3 brother at the beginning of her sophomore year of high school.
The victim described her relationship with her stepmother as
"[v]ery loving and maternal." In fact, she considers her
stepmother "[her] mother," and not the defendant.
On cross-examination, the victim, in response to a question
posed by trial counsel, stated that she told her stepmother that
the defendant had raped her. Approximately four years later, in
2021, the victim reported these incidents to the police. The
defendant testified and denied all the allegations. The
Commonwealth also called Dr. Stephanie Block as an expert
witness in the areas of children's "disclosures of abuse" and
their "memory for trauma."
2. The motion in limine and the bad act evidence at trial.
Prior to trial, the Commonwealth filed a motion in limine
(motion) to admit eight3 instances of the defendant's prior and
contemporaneous bad acts: (1) telling the victim that her
biological father never wanted a daughter or his children and
never cared for them; (2) not paying for essential utilities and
leaving her children unsupervised for hours at a time; (3)
dragging the victim's brother down the stairs while he was
inside of a sleeping bag and shaking him (sleeping bag incident)
3 For ease, we shall refer, as do the parties, to the multiple acts of violence by the defendant described in paragraph three of the motion as one act.
4 and throwing items at the wall and her children; (4) watching
the victim shower, turning the water to cold, and commenting on
her body; (5) inappropriately remarking about the victim's body
with comments such as the victim being "really tight"; (6)
commenting while intoxicated about feeling like a "pedo" when
speaking to the victim's friends and "lovers" (videorecorded by
the victim and shown to the jury); (7) refusing to bring the
victim to therapy because she did not want the victim to "talk
shit" about her; and (8) forcing the victim's brother out of the
car and leaving him on the side of the road while upset with him
(car incident).
"Before prior bad act evidence can be admitted against a
defendant, the Commonwealth must satisfy the judge that 'the
jury [could] reasonably conclude that the act[s] occurred and
that the defendant was the actor'" (citation omitted).
Commonwealth v. Leonard, 428 Mass. 782, 785 (1999). In its
motion, the Commonwealth argued that the acts were "highly
relevant to show the defendant's course of conduct, the nature
of the relationship between the defendant and the alleged
victim, her biological daughter, and the alleged victim's state
of mind." In response, at the motion hearing, trial counsel

2. The motion in limine and the bad act evidence at trial.
Prior to trial, the Commonwealth filed a motion in limine
(motion) to admit eight3 instances of the defendant's prior and
contemporaneous bad acts: (1) telling the victim that her
biological father never wanted a daughter or his children and
never cared for them; (2) not paying for essential utilities and
leaving her children unsupervised for hours at a time; (3)
dragging the victim's brother down the stairs while he was
inside of a sleeping bag and shaking him (sleeping bag incident)
3 For ease, we shall refer, as do the parties, to the multiple acts of violence by the defendant described in paragraph three of the motion as one act.
4 and throwing items at the wall and her children; (4) watching
the victim shower, turning the water to cold, and commenting on
her body; (5) inappropriately remarking about the victim's body
with comments such as the victim being "really tight"; (6)
commenting while intoxicated about feeling like a "pedo" when
speaking to the victim's friends and "lovers" (videorecorded by
the victim and shown to the jury); (7) refusing to bring the
victim to therapy because she did not want the victim to "talk
shit" about her; and (8) forcing the victim's brother out of the
car and leaving him on the side of the road while upset with him
(car incident).
"Before prior bad act evidence can be admitted against a
defendant, the Commonwealth must satisfy the judge that 'the
jury [could] reasonably conclude that the act[s] occurred and
that the defendant was the actor'" (citation omitted).
Commonwealth v. Leonard, 428 Mass. 782, 785 (1999). In its
motion, the Commonwealth argued that the acts were "highly
relevant to show the defendant's course of conduct, the nature
of the relationship between the defendant and the alleged
victim, her biological daughter, and the alleged victim's state
of mind." In response, at the motion hearing, trial counsel
told the judge that "[he] generally ha[d] an objection to the
admission of prior bad acts in the instance of uncharged conduct
5 that rises to criminal behavior." At trial, he specifically
objected to the defendant's telling the victim that her
biological father did not want a daughter or care about her or
her brother, the sleeping bag incident, and the car incident.
After a hearing, the judge allowed the motion in part. He
admitted evidence of the sleeping bag incident on the condition
that the victim testified that "[she] saw it and that there was
something about [it] that made her afraid and [that she]
continued to be afraid as she was growing up." The judge
cautioned, however, that he "[was] not sure that [he] would let
the victim get into more of the specifics" because he "[did not]
think it would be fair to the defendant and it would be
prejudicial to her if there [were] two witnesses talking about
all the facts and circumstances of [that] incident." The judge
reasoned that the acts were relevant to "show the background of
the family dynamics, which would be important in why the . . .
victim disclosed or didn't disclose and when she disclosed."
At trial, the victim testified to all eight acts, although
with a slight variation to acts four and five. The victim's
brother testified to acts two, three, and eight. Three
additional acts, that were not the subject of the Commonwealth's
motion, were elicited at trial without objection. The victim's
brother testified that the defendant (1) said that the victim
6 was "an ugly baby"; (2) put makeup on the victim that "made her
look like a clown," embarrassing the victim and prompting much
ridicule at a school dance; and (3) commented on the victim's
genitals and those of the victim's brother's girlfriend,
referring to them as "ham" and "roast beef," respectively.
Discussion. The defendant contends that the judge erred in
admitting "unduly prejudicial prior bad act evidence," that
created a substantial risk of a miscarriage of justice. "A
substantial risk of a miscarriage of justice exists when we have
'a serious doubt whether the result of the trial might have been
different had the error not been made.'" Commonwealth v.
Randolph, 438 Mass. 290, 297 (2002), quoting Commonwealth v.
Azar, 435 Mass. 675, 687 (2002). In analyzing a claim under
this standard, we review the evidence and the case as a whole
and ask four questions:
"(1) Was there error? (2) Was the defendant prejudiced by the error? (3) Considering the error in the context of the entire trial, would it be reasonable to conclude that the error materially influenced the verdict? (4) May we infer from the record that counsel's failure to object or raise a claim of error at an earlier date was not a reasonable tactical decision?" (citations omitted).
Randolph, supra at 297-298.
It is well settled that evidence of a defendant's bad
character and uncharged bad acts is not admissible to show a
defendant's propensity to commit the charged crime but may be
7 admissible if relevant for other purposes such as "common
scheme, pattern of operation, absence of accident or mistake,
identity, intent or motive." Commonwealth v. Dwyer, 448 Mass.
122, 128 (2006), quoting Commonwealth v. Marshall, 434 Mass.
358, 366 (2001). See Mass. G. Evid. § 404(b) (2025). "In
sexual assault cases, some evidence of [bad character and]
uncharged conduct may be admissible to give the jury a view of
the entire relationship between the defendant and the alleged
victim . . . ." Dwyer, supra at 128-129. "However, such
evidence should not be admitted if its probative value is
outweighed by the risk of unfair prejudice to the defendant."
Commonwealth v. Nascimento-Depina, 496 Mass. 1, 9, cert. denied,
146 S. Ct. 260 (2025). "Whether evidence is relevant in any
particular instance, and whether the probative value of relevant
evidence is outweighed by its prejudicial effect, are questions
within the sound discretion of the judge." Commonwealth v.
Smiley, 431 Mass. 477, 484 (2000), quoting Commonwealth v.
Valentin, 420 Mass. 263, 270 (1995), S.C., 470 Mass. 186 (2014).
We will not disturb the exercise of that discretion in the
absence of "palpable error" (citation omitted). Commonwealth v.
McCowen, 458 Mass. 461, 478 (2010). Without question, "the
prosecution may not introduce evidence of a defendant's prior or
subsequent bad acts for the purpose of demonstrating bad
8 character or propensity to commit the crime[s] charged"
(citation omitted). Commonwealth v. Butler, 445 Mass. 568, 574
(2005). It is also true that the Commonwealth "[i]s entitled to
present as full a picture as possible of the events surrounding
the incident itself." Commonwealth v. Bradshaw, 385 Mass. 244,
269-270 (1982).
Here, the defendant was charged with raping her daughter.
The Commonwealth alleged that the motive was not sexual
gratification, but rather to attempt to control, manipulate,
degrade, and punish the victim, something the defendant
vehemently denied. The jury were presented with a classic
credibility contest. Although the nature of the crime was woven
into the fraught family dynamics, the prior bad acts
"consist[ed] almost entirely of acts showing the defendant's
poor treatment of [the victim]." Commonwealth v. Morris, 82
Mass. App. Ct. 427, 441 (2012). To be admissible, there must be
a "logical relationship" between the prior bad act and the crime
charged (citation omitted). Commonwealth v. Facella, 478 Mass.
393, 405 (2017). In many instances these acts were untethered
to the crimes charged. Examples of this include the defendant
(1) commenting on the victim's and her brother's girlfriend's
genitals, referring to them as "ham" and "roast beef"; (2) not
paying for essential utilities; and (3) commenting while
9 intoxicated about feeling like a "pedo" when speaking to the
victim's friends and "lovers" (captured on videotape and played
at trial).
Where, as here, the defense centered on attacking the
victim's credibility, the evidence of the nature of the
relationship between the defendant and the victim arguably
provided context for the rapes that would otherwise seem
inexplicable. See Bradshaw, 385 Mass. at 269-270. However,
even if permissible for this reason, the question is whether its
probative value was outweighed by the risk of unfair prejudice
to the defendant. See Commonwealth v. Crayton, 470 Mass. 228,
249 (2014). "It is implicit in the general rule regarding the
inadmissibility of prior bad acts evidence that the admission of
such evidence carries with it a high risk of prejudice to the
defendant." Commonwealth v. Anestal, 463 Mass. 655, 672 (2012),
quoting Commonwealth v. Barrett, 418 Mass. 788, 795 (1994). The
potential prejudice is of several types:
"Such evidence compels the defendant to meet charges of which the indictment gives [her] no information, confuses [her] in [her] defen[s]e, raises a variety of issues, and thus diverts the attention of the jury from the crime immediately before it; and, by showing the defendant to have been a knave on other occasions, creates a prejudice which may cause injustice to be done [her]." Anestal, supra at 665, quoting Commonwealth v. Jackson, 132
Mass. 16, 20-21 (1882).
10 Here, the judge did not expressly weigh the probative value
of the prior bad act evidence against the risk of unfair
prejudice to the defendant. See Commonwealth v. Samia, 492
Mass. 135, 148 (2023). And we cannot say that he did so
implicitly by the admission of the evidence, see id., where the
judge indicated that he would defer certain rulings until he
heard some initial testimony, but failed to revisit the
admissibility of the bad act evidence. This causes us concern
because, "even if relevant, a judge must guard against the risk
that evidence of prior bad acts will divert the jury's attention
from the charged acts." Dwyer, 448 Mass. at 129. Here, the
sheer amount of prior bad act evidence introduced by the
Commonwealth was substantial in comparison to the evidence
presented of the crimes charged. Indeed, it risked overwhelming
the case with bad act evidence and distracting the jury from
determining whether the Commonwealth proved its case beyond a
reasonable doubt. And although it was incumbent on the
defendant to object, our cases suggest that even without an
objection, there are occasions when "[t]he judge should . . .
intervene[] to prevent" these dangers. Id. This case presents
that occasion and the judge did not do so. See Commonwealth v.
Roche, 44 Mass. App. Ct. 372, 380-381 (1998) (to guard against
unfair prejudice, judge should limit quantity of bad act
11 evidence admitted). Moreover, in a case turning almost entirely
on credibility, the prior bad act evidence may have improperly
bolstered the victim's credibility. See Commonwealth v.
Scullin, 44 Mass. App. Ct. 9, 13 (1997) (in credibility contest
"repeated references" to other acts likely made "significant
impression" on jury). See also Commonwealth v. Clark, 23 Mass.
App. Ct. 375, 381-382 (1987) (substantial risk of miscarriage of
justice created where erroneously admitted evidence could have
enhanced victim's credibility, which was "decisive issue" in
case).
Finally, the admission of bad act evidence may create a
"need [for the judge] to instruct the jury with particular care
what to do in order to avoid diversionary misuse of the
material." Commonwealth v. Mills, 47 Mass. App. Ct. 500, 505-
506 (1999). Indeed, adequate contemporaneous and final limiting
instructions may tip the balance in favor of admissibility. See
Commonwealth v. Gomes, 475 Mass. 775, 785 (2016). The judge did
not mitigate any potential prejudice by the admission of this
evidence by providing clear, forceful contemporaneous limiting
instructions, only providing them in his final charge to the
jury, as part of his entire final instructions.4 Even
4 Trial counsel did not request a limiting instruction, and failed to follow up on the judge's invitations to possibly provide one on request.
12 contemporaneous limiting instructions have sometimes been held
insufficient to prevent undue prejudice, see, e.g., Dwyer, 448
Mass. at 128-129 & n.8. Here, there were none.
Accordingly, we are constrained to conclude that the
judge's admission of extensive prior bad act evidence, without a
careful balancing of its probative value against the risk of
unfair prejudice, and without any contemporaneous limiting
instructions, despite the lack of objection, was an abuse of
discretion and created a substantial risk of a miscarriage of
justice. See Crayton, 470 Mass. at 252. See also L.L. v.
Commonwealth, 470 Mass. 169, 185 n.27 (2014).
