A Massachusetts judge declared a mistrial Friday in the murder trial of Lindsay Clancy, 36, after a jury deadlocked 11-1 on an insanity defense for the January 2023 strangulation deaths of her three children in Duxbury. The Plymouth County district attorney must now decide whether to retry the former nurse, who remains confined to a psychiatric facility.
Judge William Sullivan ended the nearly six-week televised trial on September 4 after jurors sent three notes indicating impasse. Eleven jurors favored a not-guilty-by-reason-of-insanity verdict based on postpartum psychosis testimony, while a single holdout blocked unanimity. The defense's emergency appeal to the Massachusetts Supreme Judicial Court to prevent the mistrial was denied.
The case has reignited national debate over maternal mental health treatment and legal standards for postpartum psychosis, drawing comparisons to the 2001 Andrea Yates case. Prosecutors argued Clancy planned the killings, citing evidence she mapped her husband's return time before the murders. President Trump called it a "horrible tragedy" and predicted a retrial.
Clancy's attorney Kevin Reddington accused the holdout juror of having an undisclosed agenda, while prosecutors maintain Clancy understood the wrongfulness of her actions despite mental health struggles. A status hearing is scheduled for September 29 to address the retrial decision.
