Key moments in the Lindsay Clancy case: the 911 call, mental health care, mistrial

PLYMOUTH, Mass. — A mistrial was declared in the Lindsay Clancy murder trial on Friday after jurors failed to reach a verdict on whether she was criminally responsible for killing her three young children at her Massachusetts home.

Judge William Sullivan declared the mistrial on the seventh day of deliberations after jurors sent a note saying: “It is with a heavy heart that we report we are unable to come to a unanimous decision and will not be able to.”

The emotionally charged case has sharply divided many Americans and generated intense interest for over a month as it's drawn attention to issues around maternal mental health after childbirth.

Clancy, 36, never disputed that she killed her children. But her attorney said she had a rare condition called postpartum psychosis when she strangled her kids, the youngest just 8 months old, then tried to take her own life in 2023. Prosecutors said Clancy knew what she was doing.

Here are some key moments from the trial:
