Judge Declares Mistrial in Lindsay Clancy Murder Case
A Massachusetts judge declared a mistrial in the murder trial of Lindsay Clancy after a 12-person jury deadlocked following seven days and more than 38 hours of intense deliberations. Plymouth Superior Court Judge William Sullivan officially ended the six-week trial after the panel repeatedly signaled it was impossibly divided over whether the former labor and delivery nurse was criminally responsible for the 2023 strangulation deaths of her three young children.
Court filings and jury communications indicated that the panel was split 11-1, with the vast majority favoring an acquittal based on mental illness while a single holdout juror refused to agree. According to an official news report published by The Guardian, defense attorney Kevin Reddington launched a dramatic, last-minute emergency appeal to the Massachusetts Supreme Judicial Court seeking to remove the holdout juror for alleged misconduct before Judge Sullivan finalized the mistrial order.
The high-profile trial focused on the tragic January 2023 incident inside the family’s Duxbury home, where Clancy used exercise bands to strangle 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan before jumping from a second-story window in a suicide attempt that left her paralyzed.
Throughout the proceedings, the defense maintained that Clancy was suffering from severe, unmanageable postpartum psychosis and auditory hallucinations that completely stripped her of her capacity to understand the wrongfulness of her actions. Prosecutors, led by Assistant District Attorney Jennifer Sprague, argued that Clancy acted with cold calculation, pointing to her internet searches, timing of her husband’s absence on errands, and testimony from state experts who concluded she retained legal sanity at the time of the killings.
The emergency appeal to the state’s highest court was formally denied by Supreme Judicial Court Justice Dalila Argaez Wendlandt, clearing the path for Judge Sullivan to dismiss the jury and conclude the proceedings without a verdict.
The mistrial outcome leaves the criminal case unresolved, keeping the 36-year-old mother in custody at a state psychiatric facility while Plymouth County prosecutors evaluate whether to seek a retrial, negotiate a plea agreement, or dismiss the charges. Plymouth County District Attorney Tim Cruz stated that his office would take time to review the trial record before deciding on next steps, while Judge Sullivan scheduled a formal status conference for September 29 to determine the future trajectory of the case.
