Commonwealth v. Wright, 92 N.E.3d 1175

Background

Defendant Joseph Wright admitted killing his mother and grandmother; bodies found at an elementary school; he fled to Canada and confessed to Canadian border officers.
Canadian officers read a caution; defendant asked for counsel but then spontaneously confessed; statements not recorded.
Defendant indicted in Massachusetts for two counts of first‑degree murder; defense theory was diminished capacity from long‑term substance abuse (drug‑induced psychosis); defense disclosed a psychologist (Robert Joss) and his written report pretrial but did not call him.
Pretrial, defendant moved to suppress his Canadian statements as involuntary and for lack of Miranda warnings; motion denied because Miranda does not apply to foreign interrogations and the statements were found voluntary.
At trial the judge ordered production of the defense expert’s report to the Commonwealth under Mass. R. Crim. P. 14(b)(2)(B)(iii); the Commonwealth used knowledge of that report during cross‑examination.
Jury convicted on theory of extreme atrocity or cruelty; defendant appealed raising suppression, discovery/disclosure, lack of criminal responsibility / ineffective assistance, and alleged failure to collect evidence of intoxication.

Issues

Issue	Plaintiff's Argument (Commonwealth)	Defendant's Argument (Wright)	Held
Admissibility of statements to Canadian police	Statements admissible because Miranda does not apply to foreign interrogations; admissibility rests on voluntariness	Statements were involuntary and should be suppressed; Miranda warnings required	Court: Miranda inapplicable to foreign officials; statements were voluntary and admissible
Disclosure of defense expert report under Mass. R. Crim. P. 14(b)(2)	Rule requires defendants to disclose defense expert report once defendant clearly raises mental‑condition issue and judge is satisfied defendant will testify or expert will rely on defendant’s statements; prosecution entitled to report even if it does not seek a court‑ordered exam	Production improper absent court‑ordered reciprocal exam; disclosure violated rule and defendant’s Fifth Amendment rights	Court: Judge properly ordered disclosure; rule imposes independent duty on defendant to produce report; disclosure did not violate self‑incrimination right
Lack of criminal responsibility / ineffective assistance for not asserting it	N/A (prosecution argued sanity)	Defendant asserts Joss’s report shows lack of criminal responsibility; counsel ineffective for not presenting that defense	Court: Joss’s report did not diagnose a mental disease/defect but attributed impairment to voluntary drug use; voluntary intoxication is not McHoul insanity; counsel reasonably pursued diminished‑capacity strategy; no ineffective assistance
Alleged failure to collect evidence of drug use (pill bottles, baggies) —right to present a complete defense	Photographs and materials were preserved and prosecution not required to collect additional items when exculpatory value not apparent at time	Failure to collect or preserve physical items denied opportunity to prove intoxication/diminished capacity	Court: No Trombetta violation — exculpatory value not apparent at time of collection; photos submitted to jury; no constitutional deprivation
