What is known

Lindsay Clancy, a 36-year-old American woman, is on trial in Massachusetts for the 2023 murder of her three young children at their suburban home, ABC News reports.

According to that single source, Clancy does not deny killing Cora, 5, Dawson, 3, and Callan, eight months old, on January 24, 2023.

After the children died, Clancy attempted to take her own life. The attempt left her partially paralyzed and using a wheelchair.

Opposing accounts of her mental state

The defense argues that Clancy had postpartum psychosis, a group of disorders involving the sudden onset of psychotic symptoms after childbirth. It maintains that a mental disease or defect absolves her of criminal responsibility.

The rare condition is reported to affect about one mother in 1,000. It can include hallucinations and may require psychiatric hospitalization.

The defense says Clancy's condition and desperate search for assistance led her to plead for help before deteriorating during the months after the birth of her youngest son.

Prosecutors instead portray Clancy as a functioning mother. They say she meticulously planned the killings and knew right from wrong on January 24, 2023.

Assistant District Attorney Jennifer Sprague told jurors that Clancy killed her children because she no longer wanted to be their mother.

Treatment examined during the trial

Several healthcare professionals testified, as did Patrick Clancy, the defendant's former husband. He described multiple medications with varying side effects.

Court documents show that Clancy was prescribed 13 different psychiatric medications and received more than 30 prescriptions over five months.

Sprague acknowledged that Clancy had a mental health condition. She said, however, that the trial had to determine Clancy's mental state when the killings occurred.

The prosecutor also said Clancy had access to more treatment and care than many other people. According to Sprague, Clancy wanted to get better, but on her own terms.

Closing arguments and deliberations

The parties delivered closing arguments Thursday, local time, after five weeks of trial and more than four weeks of testimony. The jury then began deliberating.
