Commonwealth v. Tassinari
466 Mass. 340

Read the full case

Background

  • Defendant admitted shooting and killing his wife in the driveway on April 22, 2008; charged with first-degree murder (deliberate premeditation and extreme atrocity/cruelty). Jury convicted on November 1, 2010.
  • Marriage had been strained for months; electronic communications, texts, and testimony showed recurring disputes about alleged infidelity, requests for divorce, and proposals for an "open marriage." Defendant repeatedly expressed jealousy and control issues.
  • On the night of the killing the couple argued; victim left briefly and returned. Multiple witnesses heard many shots; victim was shot eighteen times and died of extensive wounds. Defendant called 911 and told police he shot his wife for cheating.
  • Defense theory: the victim’s sudden oral confession of infidelity caused defendant to lose control (heat of passion) and should reduce murder to voluntary manslaughter. Defense presented testimony and a forensic psychologist supporting impulsivity but no mental illness.
  • Commonwealth’s evidence included autopsy photos, firearms and ammunition from defendant’s safe, electronic communications (including sexual-content references), witness statements about prior incidents of fear, and the defendant’s firearms training/certification.
  • Trial issues raised on appeal: admissibility of various evidence (hearsay/state-of-mind, excited utterance, autopsy and photo evidence, sexual-material evidence, firearms evidence), a juror’s dual citizenship, prosecutor’s closing, jury instructions on heat of passion, and request for 33E relief.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Admission of victim’s out-of-court statements (sister‑in‑law) Statements show victim’s state of mind and motive; admissible under state‑of‑mind exception Statements were hearsay and prejudicial Admitted: relevant to victim’s dissatisfaction and defendant’s awareness; no error (Qualls, Bins, Andrade cited)
Admission of victim’s statement to best friend (alleged assault) Commonwealth: excited utterance showing ongoing discord in marriage Defendant: not spontaneous, improperly used as bad‑act evidence Admitted as excited utterance and limited by instruction; not unduly prejudicial
Autopsy and dog photograph evidence Autopsy photos show different wounds relevant to intent/cruelty Defendant: gruesome, inflammatory; dog photo irrelevant and prejudicial Autopsy photos admissible (relevant to intent/cruelty); dog photo possibly erroneous but harmless given other evidence
Sexual/practice references and pornographic materials Relevant to state of mind and relationship context Defendant: irrelevant, propensity evidence, unfairly prejudicial Admissible in redacted form; judge screened jurors and excluded graphic materials; not improperly character evidence
Firearms, training, and NRA membership Relevant to access, choice of weapons, and familiarity supporting premeditation Defendant: unfair focus on firearms and character inference Firearms and credentials admissible as relevant to choice and premeditation; NRA membership should not have been admitted but error was harmless
Juror dual citizenship disclosed during deliberations No issue — juror qualified and impartial Defendant: juror not U.S. citizen; prejudiced right to jury of fellow citizens Judge reasonably found juror was a U.S. citizen and impartial; no shown prejudice
Prosecutor’s closing on reasonableness of provocation Prosecutor properly argued inferences from evidence Defendant: prosecutor improperly asked jury to reject heat‑of‑passion as acceptable today Remarks were permissible argument; reviewed in context of instructions and evidence
Jury instructions on sudden revelation of infidelity and burden Defendant: requested instruction that sudden oral revelation may reduce murder to manslaughter and that prosecution must disprove mitigation beyond reasonable doubt Judge refused defendant’s proposed wording but used Model Jury Instructions on Homicide No error: Model instructions allowed jury to determine whether revelation was sudden and provoking; no burden‑shifting found
