Summary
The Massachusetts Supreme Judicial Court held that the defendant’s murder conviction had to be reversed and the case remanded for a new trial. The court concluded that the trial judge improperly admitted highly prejudicial evidence of the defendant’s alleged prior abuse of her son and improperly refused to instruct the jury on excessive use of force in self-defense. The court also addressed the admissibility of prior bad acts offered as the basis for expert testimony.

Questions Presented
- Whether the trial judge committed reversible error by repeatedly admitting prejudicial details of the defendant's alleged prior bad acts involving abuse of her son.
- Whether the evidence required an instruction on excessive use of force in self-defense, which could mitigate murder to voluntary manslaughter.
- Whether the defendant's history of abuse and related expert testimony supported consideration of the reasonableness of her apprehension and use of force under G. L. c. 233, § 23F.
Holdings
- The repeated admission of detailed evidence concerning the defendant's alleged prior abuse of her son was erroneous because the evidence was not relevant to a permissible noncharacter purpose and its prejudicial effect substantially outweighed any probative value.
- The evidence required an instruction on excessive use of force in self-defense, and the refusal to give that instruction was prejudicial error requiring reversal.
Key quotations
“In other words, just because an expert is aware of, or was provided with, information does not mean that the information must automatically be disclosed to the jury.” (668-669)
“Viewing this evidence in the light most favorable to the defendant, a jury instruction on the excessive use of force in self-defense was required.” (677-678)
“Assessing the reasonableness of the defendant’s fear in light of her history of abuse, as called for by § 23F, we cannot say, viewing the evidence in the light most favorable to the defendant, that this matter should have been removed from the province of the jury.” (678-679)
Factual background
The defendant stabbed her boyfriend, Baby Petitry, in the chest with a sixteen-inch shard of glass during an argument in their Brockton apartment, causing his death. The defendant had a documented history of physical and psychological abuse, including abuse allegedly inflicted by Petitry, and defense experts testified that she suffered from post-traumatic stress disorder and may have been in a dissociative state during the stabbing. At trial, the Commonwealth repeatedly introduced details of alleged prior incidents in which the defendant had struck her young son, despite objections. The trial judge also declined to instruct the jury on excessive use of force in self-defense.
Procedural history
A Superior Court jury convicted the defendant of murder in the first degree on a theory of deliberate premeditation on September 27, 2007. After the direct appeal was entered in the Supreme Judicial Court, the court stayed the appeal to permit the defendant to file a motion for a new trial. The Superior Court denied that motion after a nonevidentiary hearing in November 2010, and the appeal from that denial was consolidated with the direct appeal.
Remand instructions
The murder conviction is reversed, the verdict is set aside, and the case is remanded to the Superior Court for a new trial. At retrial, the jury must receive an instruction on excessive use of force in self-defense if the evidence remains materially the same; the operability and significance of any second bedroom door are matters for the jury.
