Second week of Lindsay Clancy murder trial focuses on medical testimony

The murder trial of Lindsay Clancy resumed Monday in Plymouth, Massachusetts, after a week of harrowing testimony and a juror walk-through of the family home where the killings occurred in January 2023. Emergency-room physicians described the condition of the children when they arrived at hospitals, noting that eight-month-old Callan was in cardiac arrest and later died, while his sister Cora was declared dead shortly after arrival.

Prosecutors argue that Clancy acted intentionally and should be held criminally responsible for the deaths of Callan, Dawson and Cora, aged eight months to five years. The defense maintains that she suffered from postpartum psychosis, a severe psychiatric disorder that can distort reality, and that her actions were driven by that illness.

Clancy, 35, was visibly emotional at the defense table as her ex-husband Patrick Clancy and other witnesses recounted the events. Patrick Clancy testified that he discovered the children in the basement and his wife injured on the ground after she jumped from a second-floor window, leaving her paralyzed from the waist down.

Lawyers for Clancy do not dispute that the children died, but contend that she had an undiagnosed bipolar disorder that worsened under a complex regimen of antidepressants, sleep aids and antipsychotics prescribed in the months preceding the murders. According to the defense, she sought help for postpartum depression in December 2022, was advised to taper off an antipsychotic, and was briefly hospitalized on New Year’s Eve before returning home.

A day before the killings, Clancy’s attorneys say she reported hearing a commanding voice urging her to kill the children. Prosecutors portray her request for her husband to run errands that evening as a tactic to leave the house unattended.

In a separate civil lawsuit, the Clancys allege medical providers failed to recognize the risk she posed, claims the providers deny. Prosecutor Shanan Buckingham told jurors that the case is not a debate about women’s mental health, emphasizing that the focus should remain on the defendant’s criminal responsibility.

If convicted of murder, Clancy faces life imprisonment without parole; a verdict of not guilty by reason of insanity would result in commitment to a state mental-health facility.
