A shocking crime inside a seemingly ordinary American family has raised questions about mental illness and criminal responsibility
Jury selection has begun on Monday in a closely watched murder trial of a Massachusetts mother accused of killing her three young children in a case that has drawn nationwide attention.
A shocking crime inside an otherwise ordinary American family has raised broader questions about mental illness, psychiatric treatment, and criminal responsibility, with jurors expected to hear sharply conflicting accounts of Lindsay Clancy’s mental state at the time of the killings.
Clancy, a former labor and delivery nurse, has pleaded not guilty to murdering her daughter Cora, 5, her son Dawson, 3, and eight-month-old son Callan at the family’s home in Duxbury, Massachusetts in January of 2023. Prosecutors allege she deliberately strangled the children while her husband was picking up takeout, before attempting suicide by jumping from a second-story window, leaving her paralyzed.
The defense is expected to pursue an insanity defense, claiming Clancy was suffering from postpartum psychosis after months of worsening psychiatric symptoms, repeated hospitalizations, and multiple medication changes. Her attorneys contend she sought medical help before the tragedy and was unable to appreciate the wrongfulness of her actions.
Acknowledging that Clancy killed her children, defense lawyer Kevin Reddington has argued she should not be held criminally responsible because of her mental state.
“Our society fails miserably in treating women with postpartum depression or even postpartum psychosis,” Reddington said during a 2023 arraignment hearing. “This is a situation that clearly was a product of mental illness.”
Prosecutors reject that account, maintaining the killings were intentional and carefully planned. They are expected to present evidence they say shows Clancy acted with deliberation, including sending her husband on an errand before the children were killed.
The children’s father, Patrick Clancy, who discovered their bodies, is expected to testify. In addition to the criminal proceedings, both he and Lindsay Clancy have filed separate civil lawsuits against the mental health providers who treated her before the killings, alleging that failures in her psychiatric care contributed to the tragedy.
The trial is expected to last several weeks and feature extensive testimony from psychiatrists, medical experts, and treating physicians about postpartum psychosis, a rare but severe disorder that can develop after childbirth. Jurors will ultimately be asked to decide whether Clancy was legally responsible for one of the most shocking family tragedies in recent US history.
