Prosecution Seeks Not Criminally Responsible Verdict
3.0
In Montreal on Dec. 5, 2025, Quebec Superior Court heard a joint submission that Arthur Galarneau, 22, was not criminally responsible for the March 17, 2023 murders of his parents and grandmother. Crown and defence presented psychiatrist testimony diagnosing schizophrenia and delusions, arguing he lacked moral culpability; Justice Annie Émond will rule on Jan. 22, 2026.
Key Points
- 1Joint submission states Galarneau suffered schizophrenia and was delusional during March 17, 2023 killings.
- 2Psychiatrist testified he lacked notion of right or wrong, supporting a not criminally responsible finding.
- 3Judge will decide Jan. 22; Crown may seek high-risk designation restricting freedom or hospital release.
Scoring Rationale
Official joint court submission provides credible legal update, but local criminal case has limited novelty and narrow relevance.
