Criminal Defense Attorney Argues Postpartum Psychosis Should Shield Mother From Murder Conviction

A criminal defense attorney representing a Massachusetts mother accused of killing her three children argues she suffered from postpartum psychosis and should not be held criminally responsible, despite prosecutors contending she acted deliberately and rationally. The case has ignited fresh debate about how American courts address infanticide by mothers experiencing severe postpartum mental illness—a legal question that most U.S. states have largely avoided for decades.

The Incident and Charges

On the evening of January 24, 2023, Patrick Clancy returned to his Duxbury home to discover his three children motionless in the basement. Each had an exercise resistance band around their neck. The children—Cora, 5 years old; Dawson, 3; and Callan, 8 months—were deceased. Their mother, Lindsay Clancy, 35, a former labor and delivery nurse, had subsequently cut her wrists and neck and jumped from a second-floor window in what her defense team characterizes as a genuine suicide attempt that left her partially paralyzed.

Clancy does not contest that she killed her children. However, her criminal defense attorney, Kevin Reddington, maintains in opening arguments that she should not face criminal conviction given her mental state. The trial is expected to last up to eight weeks and will heavily feature expert testimony about postpartum mental illness. Prosecutors argue Clancy acted "intentionally, rationally, and swiftly" to accomplish a specific objective, rejecting claims she was experiencing psychosis at the time. If convicted, she faces life imprisonment.

The International Legal Framework and U.S. Divergence

The case has prompted legal scholars and mental health advocates to revisit a 1936 English trial that established a precedent many nations have since adopted. When Brenda Hale, a British mother, killed her infant three weeks after childbirth and attempted suicide, a jury determined she was not culpable due to "puerperal insanity"—mental illness triggered by the postpartum period. That verdict led England and Wales to create statutory protections allowing courts to treat infanticide by mothers differently from other homicides, potentially resulting in mental health treatment rather than lengthy prison sentences.

Nearly two dozen countries have since adopted similar frameworks, but the United States has largely rejected this approach. Illinois stands alone among American states in granting special consideration to mothers suffering from postpartum mental illness who commit infanticide—though only during sentencing after a guilty verdict has been rendered. Massachusetts and several other states have considered comparable legislation, but none have passed comprehensive protections. Jessie Colbert, coordinator of the Massachusetts Mind the Gap Coalition, has emphasized that "the criminal justice system needs to be updated to understand this illness" and that legal standards require "more clarity and more fairness."

Broader Questions About Law and Culpability

The Clancy trial reflects a centuries-old tension in how society perceives mothers who kill their children. Experts note that public perception often bifurcates these cases into competing narratives: mothers are viewed as either fundamentally evil or profoundly mentally ill. The legal and medical questions raised by postpartum psychosis—including issues of culpability, mental health treatment versus punishment, and deeply ingrained stereotypes about women—remain unresolved in American jurisprudence. The trial outcome may influence whether additional states reconsider statutes addressing maternal infanticide in the postpartum period.
