The jury in the Lindsay Clancy trial has reached an impasse after more than three days of deliberations, with jurors unable to reach a unanimous decision on whether the Massachusetts mother was criminally responsible for killing her three young children.
Clancy, a former labor and delivery nurse, is charged with murder in the deaths of her 5-year-old daughter, Cora, 3-year-old son, Dawson, and 8-month-old son, Callan.
She has pleaded not guilty by reason of lack of criminal responsibility, claiming she suffered from postpartum psychosis at the time of the killings. Prosecutors argue that she knew what she was doing.
On Tuesday, Judge William Sullivan instructed the jury to continue deliberating despite their deadlock. “I know that this was a long trial, all right,” he said. “I know there were over 300 exhibits. But because of that, I’m going to ask you to go back out.”
Clancy, 36, does not dispute that she strangled her children but contends that her mental state was to blame. The attorney argued during the trial that she loved her children but lost her grip on reality due to postpartum psychosis, a rare mental illness that can occur after childbirth.
The defense and prosecution presented differing views from medical experts on Clancy’s mental state and culpability. A conviction could result in a life prison sentence, while an acquittal could lead to confinement in a mental health facility if she is deemed a danger to the public.
Massachusetts law requires a defendant to prove lack of criminal responsibility by showing they could not distinguish right from wrong at the time of the act. The burden rests on the defense, and jurors must weigh expert testimony against the factual record.
During deliberations, they asked to review a knife and bags with empty prescription pill bottles found in Clancy’s house. They also listened to testimony from her former husband, Patrick Clancy, who discovered the bodies and made an anguished 911 call.

The community remains divided.
Tensions run high.
Family members of the victims expressed grief and called for accountability. Local advocacy groups highlighted the need for better postpartum support services.
Postpartum psychosis affects an estimated 1 to 2 out of 1,000 women after delivery. Although most women with the condition do not harm their children, those with severe cases may harm themselves or their children.
Jurors began deliberating on Thursday afternoon and spent two days listening to testimony from her former husband, Patrick Clancy, and his anguished 911 call, during which he was still on the line when he discovered the children’s bodies and found his wife badly injured in the yard.
Both Clancy’s mother and sister testified that she became anxious, paranoid, and suicidal in the months leading up to the tragedy.
Less than three weeks after being discharged from a psychiatric hospital where she sought treatment for worsening mental health, Clancy sent her husband out on an errand and killed the children with exercise bands in the basement of their home south of Boston.
She then jumped from a second-floor window and remains paralyzed from the waist down.
