Core Event: Triple Murder Trial and Closing Arguments
The Plymouth Superior Court is hearing the case of Lindsay Clancy, accused of strangling her three children—Cora, Dawson and Callan (8 months)—in Duxbury, Massachusetts, in January 2023. She faces three counts of first-degree murder and, if convicted, life imprisonment without parole. Closing arguments follow 21 days of testimony and more than 70 witnesses.
Background & Context
The trial has drawn national attention to postpartum mental-health disorders. PBS NewsHour notes that up to one in five women experience a perinatal mood disorder, while postpartum psychosis affects roughly one in 1,000 women and is considered a medical emergency. Experts say the condition is “temporary, treatable” but often goes unrecognized because symptoms can wax and wane and the disorder is not listed in the DSM-5.
Expert Testimony
Prosecution experts—including FBI forensic psychiatrist Gregory Saathoff and forensic psychologist Kirk Heilbrun—argued that Clancy planned the killings, drove a car, and communicated with a pediatrician on the day of the murders. Saathoff said she deliberately planned to kill herself and her children and was in control of her actions. Heilbrun diagnosed bipolar II disorder, described her as “still grieving,” and noted the alleged command hallucination occurred only once, which he said is atypical for psychosis.
Defense experts—including forensic psychologist Paul Zeizel and psychiatrist Phil Resnick—maintained that Clancy suffered postpartum psychosis, characterized by a “command hallucination” that told her to kill the children and herself. Resnick described the experience as a “delusion of influence,” asserting that Clancy felt her body was taken over by an external force and lacked the capacity to conform to the law.
Official Statements & Responses
Judge William Sullivan instructed jurors to disregard a line of questioning about Catholic doctrine raised by Heilbrun and admonished the prosecution to avoid religious arguments. Prosecutor Shanan Buckingham emphasized that the evidence shows Clancy retained the mental capacity required for criminal responsibility. Defense attorney Kevin Reddington challenged the timing of Heilbrun’s evaluation, noting it was conducted more than three years after the killings, and repeatedly asked the court to exclude references to religion.
Criticism & Opposition
Commentary outside the courtroom has focused on the trial’s public narrative. Deputy district attorney Jonathan Hatami said the focus should remain on the victims rather than the defendant’s personal story.
Conflicting Reports & Gaps
The prosecution cites bipolar II disorder and questions the validity of a single command hallucination, while the defense asserts a postpartum psychosis episode with a command hallucination. Heilbrun’s assessment, conducted years after the incident, raises concerns about recall bias, a point noted by both sides. No consensus exists on whether Clancy’s mental state met Massachusetts’ legal standard for insanity—knowing right from wrong or being unable to conform to the law.
Verbatim Quote
- “Not only did she hear a command, but she felt that her body was taken over by an external force where she was in a dream state and did not have control of her own body,” — Phil Resnick, forensic psychiatrist
What’s Next
After closing arguments, jurors will deliberate. A not-guilty verdict by reason of insanity would commit Clancy to a state mental-health facility with periodic reviews; a guilty verdict would result in life imprisonment without parole. The outcome is expected to influence discussions about postpartum mental-health care and legal standards for insanity defenses.
