Dr. Gregory Saathoff, a forensic psychiatrist at the University of Virginia and senior psychiatrist for the FBI Behavioral Analysis Unit, testified that he did not believe Lindsay Clancy's account of hearing a voice ordering her to kill her three children. Clancy, 36, has pleaded not guilty to murder charges in Plymouth, Massachusetts, while the defense concedes she killed the children in January 2023 and attempted suicide afterward. The trial, now in its fourth week before Judge William Sullivan, centers on whether postpartum psychosis negated criminal responsibility.
