Her attorney argues she was suffering from postpartum psychosis and extreme mental illness when she killed them.
• Opening statements are set to begin today in the triple-murder trial of Lindsay Clancy, the Massachusetts mother who has argued she is not criminally responsible for fatally strangling her three young children, Cora, 5; Dawson, 3; and 8-month-old Callan.
• Clancy has pleaded not guilty to three counts of murder and faces life in prison if convicted. Her attorney has argued she was suffering from postpartum psychosis and extreme mental illness when she killed them.
• The testimony is expected to focus heavily on dueling psychiatric and medical experts testifying about postpartum mental illness. The key witness in the case could be her husband Patrick Clancy, who has indicated he shares his wife’s perspective on mental illness. “I wasn’t married to a monster — I was married to someone who got sick,” he said in a 2024 interview.
• Editor’s note: Coverage of this story contains graphic descriptions of child killings, suicidal ideation, and an attempt to die by suicide.
