Lindsay Clancy Murder Trial: Post-partum Psychosis, Evidence and the Stipulation Deal
8/5/2026, 12:01:32 AM
Core Event
On January 24 2023 in Duxbury, Massachusetts, Lindsay Clancy strangled her three children—Cora, Dawson and infant Callan (8 months)—with exercise-resistance bands in the basement. She then cut her wrists and neck and jumped from a second-story window, surviving but becoming paraplegic. She has pleaded not guilty to three counts of first-degree murder and is asserting an insanity defense based on postpartum psychosis.
Background & Context
Clancy, a former labor-and-delivery nurse, had been treated for escalating anxiety, insomnia, depression and intrusive thoughts after Callan’s birth in May 2022. Police recovered notebooks, a postpartum-anxiety workbook and the book *Good Moms Have Scary Thoughts* from the home. In a civil lawsuit filed by the children’s estate, Clancy alleges a “catastrophic failure” by multiple providers to recognize her danger to self and others. Prosecutors argue the defense’s focus on mental-health treatment does not excuse the deliberate killings.

Official Statements & Responses
- “This is not a public debate about women’s mental health and how the medical system treats women,” — Prosecutor Shanan Buckingham.
- “This is a woman that did not get the medication, did not get the medical treatment that she so deserved,” — Kevin Reddington, defense attorney.
- “This stipulation basically relieves the government of having to bring in dozens of witnesses to prove chain of custody of blood, fluids, the [exercise] bands, DNA, all of that,” — Kevin Reddington.
Criticism & Opposition
Prosecutors have highlighted that Clancy’s wrist and neck cuts were “superficial” (Dr. Kelly McDonough) and questioned whether she truly experienced psychosis at the time of the murders. Defense cross-examination noted that a patient can be “honest” about symptoms while still being in a psychotic state.
On-the-Ground Reports
First-responder Officer Brian Josephine recounted hearing Patrick Clancy’s 911 call: “She killed the f—-ing kids!” Jurors visited the basement where the children were found and the yard where Clancy landed after her fall, providing a visceral sense of the crime scene.
Conflicting Reports & Gaps
- Dr. Sejal Shah’s Jan 30 assessment recorded no hallucinations, whereas defense experts argue postpartum psychosis can allow coherent communication despite delusions.
- Blood-stain analyst Maureen Hartnett said she could not confirm whether all red-brown stains were human blood, leaving the source of some evidence unsettled.
What’s Next
The stipulation limits the Commonwealth’s need to prove certain forensic details, shifting the trial’s focus to expert testimony on Clancy’s mental state at the time of the killings. Jurors are expected to deliberate later this month on whether she will be sentenced to life imprisonment or committed to a state psychiatric facility.
