Lindsay Clancy Trial: FBI Psychiatrist Reveals the Voice That Told Her to Kill Pt 1

Dr. Gregory Saathoff, a forensic psychiatrist who's consulted with the FBI's Behavioral Analysis Unit, spent today explaining what he found when he sat down with Lindsay Clancy — the Duxbury, Massachusetts mother accused of strangling her three children, 5-year-old Cora, 3-year-old Dawson, and 7-month-old Callan, with exercise resistance bands inside the family's Summer Street home on January 24, 2023. Clancy faces three counts of murder and three counts of strangulation. She's pleaded not guilty, and her attorney Kevin Reddington is building an insanity defense around severe postpartum psychosis and psychiatric overmedication.

Saathoff isn't new to this territory — he told the court he's evaluated and treated five to seven women in the prison system who killed their children, and co-authored a paper on postpartum psychosis back in the 1980s. He drew a line for jurors between psychosis, which he called a symptom rather than a standalone illness, and the diagnoses that can produce it. He also walked through the difference between Serious Mental Illness — schizophrenia, bipolar I — and Any Mental Illness, the broader category that includes things like anxiety and PTSD.

The heart of his testimony: after interviewing Clancy over Zoom for roughly 11 hours across May and June 2026, Saathoff said she described an external voice that surfaced while making dinner, right after hanging up with Patrick Clancy — telling her this was her last chance, that she had to kill the kids and then herself. He testified the voice stopped once she strangled Callan, her youngest, but had already gone quiet before she attempted suicide. He flagged that as unusual, along with inconsistencies between her account and what collateral witnesses told him — including the decision to order Three V takeout, and Clancy allegedly steering her husband toward a specific drugstore to keep him out of the house longer.
