A mistrial has been declared in the Massachusetts (northeastern US state) trial of Lindsay Clancy, accused of strangling her three young children in January 2023, after a single juror refused to acquit her despite admitting he had reasonable doubt about her guilt. Jury foreperson Roni Carlson told NBC 10 Boston that the holdout acknowledged his doubt but still refused to return a not-guilty-by-reason-of-insanity verdict, with fellow juror Paula Devlin describing him as "very arrogant" and unwilling to consider others' arguments. Clancy, whose defence argued she suffered a psychotic break linked to postpartum depression and overmedication, remains held at a psychiatric hospital ahead of a status hearing scheduled for 29 September; prosecutors have not yet announced whether they will retry her.
