Lindsay Clancy Murder Trial Begins in Massachusetts

Opening arguments began Monday in the murder trial of Lindsay Clancy, the Massachusetts woman accused of killing her three young children in their Duxbury home in January 2023.

Clancy has pleaded not guilty, with her defense team signaling it will pursue an insanity defense, arguing she was suffering from severe postpartum mental health issues and that her doctor's treatment only made them worse.

The case has drawn national attention to the issue of postpartum psychosis and its potential role in violent crimes.

Clancy's attorneys contend she was failed by the medical system before the tragedy occurred.
