Lindsay Clancy, 36, is on trial for the murder of her three children, aged 8 months to 5 years, in January 2023. During the trial, psychologist Paul Zeizel testified that Clancy was suffering from bipolar disorder and postpartum psychosis, which impaired her ability to understand the wrongfulness of her actions.124
Zeizel stated, "She was unable to conform her behavior to the rule of law. She had no appreciation for the wrongfulness of her act," emphasizing that Clancy had a mental disease or defect. He spent over 35 hours with her and reviewed her medical records, noting her severe mental state leading up to the incident.
Prosecutors argue that Clancy planned the killings, having sent her husband out for medicine and dinner, while she exhibited signs of psychosis, including paranoia and fear of losing her children. Zeizel explained that postpartum psychosis affects 1 to 2 per 1,000 women after childbirth, making it a rare but serious condition.
Despite her psychotic state, Zeizel acknowledged that Clancy was capable of performing everyday tasks, such as taking her daughter to the doctor and searching online for a pharmacy. This complexity raises questions about her mental state at the time of the killings.5
The trial continues as the defense seeks to establish Clancy's lack of criminal responsibility due to her mental health issues.
“Zeizel, who spent over 35 hours with Clancy, said she showed signs of psychosis and feared losing her children, but could still perform everyday tasks like driving. Prosecutors allege she planned the January 2023 killings and sent her husband out for medicine and dinner.”
