Clancy denies first-degree murder charges in the 2023 strangulation deaths of her three children, arguing she suffered from severe postpartum psychosis.
The second week of testimony in the high-profile Massachusetts murder trial brought forward a wave of emotional testimony from friends, former colleagues, and family members. Prosecutors are pressing to prove that Clancy acted intentionally when she strangled 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan on January 24, 2023. Defense attorneys maintain that a combination of overmedication and extreme psychiatric distress stripped her of criminal responsibility.
Autopsy Testimony and Courtroom Emotion
Medical Examiner Kimberley Springer walked jurors through the autopsy of 8-month-old Callan Clancy, detailing injuries consistent with ligature strangulation and mechanical asphyxia. The presentation of photographic evidence prompted loud sobbing from the defendant, forcing Judge William Sullivan to call an unscheduled break.

Superior Court Judge William Sullivan previously ordered the 911 call made by Patrick Clancy and autopsy photographs impounded for court viewing only, following a motion from the children’s father to spare relatives and the public from graphic media dissemination.
Friends Detail Dark Thoughts and Medication Struggles
Testimony from close associates revealed mounting distress in the weeks leading up to the tragedy. Amy Bevins, a friend of 29 years, told the court that Clancy had communicated via text about adverse reactions to her psychiatric medications.
Bevins added that Clancy expressed hope that she was moving in a positive direction as she adjusted her regimen. Another neighbor, Bethany DeCollibus, testified that Clancy described feeling like a zombie and struggled persistently with insomnia following the birth of her third child.
Christopher Clancy Testifies on Family Life Before the Killings
The jury also heard from Christopher Clancy, the father of Patrick Clancy and the former father-in-law of the defendant. He entered the courtroom accompanied by a priest and described the household as like the all-American family,
noting that his former daughter-in-law had appeared happy during Christmas gatherings in late 2022.

However, Christopher Clancy acknowledged that he knew his daughter-in-law was not feeling well and had visited an emergency room where his wife worked. He stated that he had previously offered to take the grandchildren for a night to give the couple a break, but his son declined.
Dueling Legal Arguments Over Mental State
Defense attorney Kevin Reddington argues that Clancy suffered from severe postpartum psychosis, a rare condition affecting women after delivery, which can induce hallucinations, paranoia, and delusions. Reddington contends that auditory hallucinations drove the actions on January 24, 2023.
In contrast, prosecutors have pointed to actions such as sending her husband out on household errands as an intentional ruse. State Police Sergeant Andrew Chiachio also introduced a May 2021 Facebook post where Clancy wrote about parenting frustrations with her son Dawson, though cross-examination confirmed investigators found no evidence of physical abuse.
As the trial continues in Plymouth Superior Court, Judge Sullivan has taken under advisement a defense motion allowing expert medical testimony regarding adequate treatment and the legitimacy of Clancy’s subsequent suicide attempt.
