Commonwealth v. Berry, 2 N.E.3d 177

defendant convicted of first-degree murder on extreme atrocity/cruelty theory; conviction reversed due to erroneous jury instructions on lack of criminal responsibility; retried in 2011 and again convicted; §33E review sought to reduce degree or grant new trial; defendant had long-standing bipolar/schizoaffective disorder and a cerebellar tumor with post-removal improvement; evidence showed tumor and mental illness intertwined with conduct at crime time; trial included expert Murphy who testified to criminal responsibility but gave erroneous law statement on cross-examination; court remands for reduction to second-degree murder; jury found criminal responsibility but court considers fairness given mental illness and tumor; expert and medical records show behavior changes linked to brain pathology and alcohol interactions; court recognizes Cunneen factors and considers defendant’s state of mind in evaluating extreme atrocity/cruelty

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Murphy’s erroneous legal statement warranted reversal	Murphy misstated law on responsibility, prejudicing defense	Juror weight, not admissibility, error; limited impact	No reversible error; minimal effect on jury
Whether § 33E requires reducing first-degree murder to second-degree	jury finding of responsibility should stand; no miscarriage	mental illness and tumor justify reduction	Verdict reduced to second-degree murder; remanded
Whether defendant’s mental illness and cerebellar tumor justify reduction under Cunneen framework	unnecessary to consider state of mind; focus on method	mental impairment intertwined with conduct; supports reduction	Yes; unique circ. supports reduction to second degree
Whether state of mind should be considered in extreme atrocity/cruelty findings more broadly	State of mind not required beyond Cunneen factors	State of mind should be relevant beyond intoxication cases	Court contemplates potential jurisprudence future considerations; invites broader reconsideration
Whether the murder conviction should stand despite substantial mental illness evidence	Conviction consistent with law given jury’s finding	Justice requires lesser degree due to impairments	Reduced to second-degree; remanded
