Lindsay Clancy case ends in mistrial after jury deadlock
Judge William Sullivan declared a mistrial on September 4, 2026, in the case of Lindsay Clancy, the Massachusetts woman who killed her three young children, after jurors failed to reach a unanimous verdict.
The 12-member jury deliberated for seven days. Eleven jurors favoured finding Clancy not guilty by reason of insanity, but one juror opposed that outcome. A verdict in a US criminal trial requires unanimity.
Prosecutors must now decide whether to try the case again with a new jury. Plymouth County District Attorney Tim Cruz told reporters he would make that decision shortly. Clancy will remain at a psychiatric institution pending a possible new trial.
Clancy, 36, acknowledged strangling Cora, five, Dawson, three, and Callan, eight months, at the family home in Duxbury, Massachusetts, in January 2023. She pleaded not guilty by reason of insanity.
Her lawyers said she was suffering from postpartum psychosis and heard a voice ordering her to kill her children. Prosecutors rejected that argument, saying Clancy had carefully planned the killings and was able to understand the consequences of her actions.
The televised trial included more than 80 witnesses. Psychiatrists, people close to Clancy and her former husband were among those who testified about her mental health. Reddington said during closing arguments that Clancy had repeatedly sought help before the killings but received “lousy medical care”.
After the killings, Clancy cut her neck and wrists and jumped from a second-story window in an apparent suicide attempt that left her paralyzed from the waist down and using a wheelchair.
She faced life in prison without parole if convicted of first-degree murder. Jurors also had the option of convicting her of second-degree murder or manslaughter, or finding her not guilty by lack of criminal responsibility, which would lead to confinement in a psychiatric facility.
President Donald Trump called the case “a horrible tragedy” and said he assumed there would be another trial.
