Lindsay Clancy Trial: Postpartum Psychosis Defense Meets Public Outcry
8/21/2026, 4:13:23 AM
Core Event
Lindsay Clancy, a 36-year-old former labor-and-delivery nurse, is on trial in Plymouth Superior Court for three counts of first-degree murder for the January 24, 2023, strangulation deaths of her children—Cora, Dawson and Callan (8 months). Clancy has pleaded not guilty, asserting postpartum psychosis prevented her from appreciating the wrongfulness of her actions. Jury selection began July 20, opening statements July 27. Judge William Sullivan has warned jurors not to speculate about procedural interruptions.
Background & Context
Postpartum psychosis is a rare psychiatric emergency that can follow childbirth, marked by hallucinations, delusions and loss of reality testing. Massachusetts follows the Model Penal Code’s two-part insanity test: a defendant is not criminally responsible if, because of a mental disease or defect, she lacks substantial capacity either to appreciate the criminality of her conduct or to conform her conduct to the law. The prosecution bears the burden of proof.
Data & Statistics
- Researchers estimate postpartum psychosis affects 1 to 2 per 1,000 women after delivery.
- Prosecutors noted Clancy was prescribed 13 psychiatric medications in the four months before the killings.
- The defense’s expert psychologist said Clancy experienced “intrusive thoughts” and “auditory hallucinations” in December 2022.
On-the-Ground Reports
Hundreds of supporters gathered outside the Plymouth courthouse on August 20, many wearing pink shirts with slogans such as “Believe.” Organizer Renee Kimball led a silent hour, a circle prayer and a display of international flags, emphasizing solidarity with women facing postpartum mental-health challenges. The rally was the first large-scale public demonstration during the month-long trial.
Official Statements & Responses
- Defense attorney Kevin Reddington argues that Clancy’s bipolar disorder with postpartum psychosis eliminated her criminal responsibility and that over-medication worsened her condition.
- Assistant District Attorney Shanan Buckingham maintains that Clancy planned the murders, citing the deliberate sending of her husband on errands and the use of exercise bands to strangle the children.
- Judge William Sullivan instructed the jury that the case hinges on whether Clancy possessed the requisite mental capacity and cautioned against speculation regarding unforeseen courtroom interruptions.
Criticism & Opposition
Defense-side attorney Donna Rotunno called the prosecution “tone-deaf,” criticizing questions about religious belief as irrelevant and inflammatory. The comment highlights tension over the prosecution’s strategy and its perceived impact on juror perception.
Conflicting Reports & Gaps
- Voice claim: Chaplain Cavanaugh reported Clancy described hearing a commanding male voice, yet prosecutors note Cavanaugh’s notes contain no documentation of this claim.
- Diagnosis: The defense asserts Clancy suffered postpartum psychosis, while prosecutors point out she was never formally diagnosed with the condition before the killings. Both sides present expert testimony supporting opposite conclusions.
Verbatim Quotes
- “I'm not there to evaluate the patient; I'm there to bear witness to their suffering," Cavanaugh said, noting that she is not medically trained and her notes aren't meant to be verbatim transcripts of conversations.” — Sheila Cavanaugh, chaplain
- “Women are being dismissed, neglected and ignored when we speak up,” — April Vincent
- “She really loves them and misses them and thinks of them every single day, almost every moment of the day,” — Paul Zeizel, psychologist
What’s Next
Judge Sullivan indicated that closing arguments are slated for August 24. After arguments, the jury—18 members—will receive instructions on the Model Penal Code standard and must reach a unanimous verdict. A conviction carries life imprisonment without parole; an acquittal would result in commitment to a state mental-health facility.
