Judge declares mistrial in Lindsay Clancy murder case after jury deadlock
Massachusetts Judge William Sullivan declared a mistrial on Friday after jurors failed to reach a unanimous verdict across seven days of deliberations in the Lindsay Clancy murder trial.
Mistrial declared in Plymouth Superior Court
Judge William Sullivan declared a mistrial on Friday in the murder trial of Lindsay Clancy after a 12-member jury failed to reach a unanimous verdict. Clancy, a 36-year-old former nurse, faced three counts of first-degree murder in Plymouth Superior Court in Massachusetts. The decision followed seven days and approximately 40 hours of deliberations without consensus. The trial panel consisted of nine women and three men, who had heard seven weeks of evidence and witness testimony.

Deliberations and the emergency appeal
On Friday morning, the jury sent a third notice confirming their deadlock, stating they were unable to reach a unanimous decision. Defense attorney Kevin Reddington attempted a last-minute intervention by requesting the replacement of a single dissenting juror and seeking an emergency stay. Reddington argued before Massachusetts Supreme Judicial Court Justice Dalila Argaez Wendlandt that the holdout juror failed to follow instructions, but Wendlandt rejected the petition. Following the dismissal of the appeal, Judge Sullivan resumed proceedings and formally ended the trial.
They know that one man stole from them, whatever his agenda was. He stole seven weeks of life from the other jurors, who were very attentive, beautiful, wonderful, and listened to the evidence.
The January 2023 killings and medical defense
The charges stem from events on 24 January 2023 at the family home in Duxbury, south of Boston. Patrick Clancy returned home from picking up takeout dinner and found the couple's three children in the basement. Five-year-old Cora and three-year-old Dawson died at the scene, while eight-month-old Callan died days later; all three had been strangled with exercise bands. Lindsay Clancy then jumped from a second-story window, an action that left her partially paralyzed. Clancy admitted to killing the children but entered a plea of not guilty. Defense attorneys argued she suffered from postpartum depression and psychosis that rendered her unable to distinguish right from wrong. In contrast, prosecutors led by Plymouth County District Attorney Timothy J. Cruz argued that Clancy acted intentionally and with full awareness of her conduct.

Potential retrial and legal next steps
Clancy remains in medical custody at a psychiatric facility, where she has been held since her arrest in 2023. If convicted of first-degree murder, she faces life imprisonment without parole, whereas a verdict of not guilty by reason of insanity would result in commitment to a high-security state psychiatric hospital. District Attorney Timothy J. Cruz must now determine whether to retry Clancy before a different jury on first-degree murder or reduced charges, such as second-degree murder or manslaughter. Alternatively, both parties could negotiate a plea agreement. Outside the courthouse, supporters wearing pink shirts gathered during the proceedings, reflecting sustained interest in the medical defense arguments.
