Massachusetts mother’s murder trial to focus on postpartum psychosis claims

A Massachusetts jury is expected to begin deliberations next week in the case of Lindsay Clancy, who is charged with murdering her three children in January 2023. The defense argues that Clancy suffered from postpartum psychosis and bipolar disorder, while prosecutors maintain she acted with full awareness of her actions.

During the week, several expert witnesses testified. Hospital chaplain Sheila Cavanaugh said Clancy reported hearing a persistent male voice that commanded her to kill her children, and described Clancy’s emotional state as “very neutral, a flat affect.” Forensic psychologist Paul Zeizel, who reviewed Clancy’s medical records, recalled a phone conversation in which Clancy claimed the voice told her she had no choice but to kill her children and then herself. Forensic psychiatrist Dr Phillip Resnick, who has consulted on similar cases, testified that Clancy was “frankly psychotic” on the day of the killings, experiencing command hallucinations and a delusion of external influence.

Prosecutors called psychiatrist Dr Avram Mack, who testified that Clancy suffered a major depressive episode in 2022-2023 but appeared generally cooperative and did not exhibit significant abnormalities. He explained that under Massachusetts law, criminal responsibility requires the defendant to understand the wrongfulness of her conduct, a standard the prosecution says Clancy met.

The trial has drawn public attention to maternal mental-health care. Hundreds of women gathered outside the courthouse, wearing pink shirts with messages calling for better support for postpartum patients. Closing arguments are scheduled for next week, and a verdict could result in either a life-without-parole sentence or confinement in a state psychiatric facility with periodic review. A separate civil lawsuit against mental-health providers involved in Clancy’s care remains pending.
