- Judge William Sullivan declared a mistrial on September 4, 2026, after seven days of jury deliberations without a unanimous verdict.
- Lindsay Clancy faced trial for the January 2023 killings of her three children; she pleaded not guilty by reason of insanity due to postpartum psychosis.

- The case has ignited national debate on how criminal justice addresses maternal mental health defenses.
The trial of Lindsay Clancy, a 36-year-old former labor and delivery nurse charged with the deaths of her three children on January 24, 2023, ended in a mistrial on September 4, 2026. After seven days of jury deliberations, the panel could not reach a unanimous verdict.
Clancy admitted to the act but pleaded not guilty by reason of insanity, citing postpartum psychosis as the underlying cause. Prosecutors maintained that she acted with awareness of her actions despite her mental health condition, asserting intent. The jury deadlock reflects the difficulty courts face in cases involving mental health defenses.
Defense attorney Kevin Reddington immediately filed an emergency appeal asking Judge William Sullivan for a not-guilty ruling due to insufficient evidence. Sullivan denied this request and then declared the mistrial without dismissing any jurors.
Plymouth District Attorney Timothy Cruz commented on the trial's outcome, stating, "We are deeply disappointed the jury could not reach a unanimous verdict but respect the legal process and will carefully evaluate next steps." WCVB News reported on the DA's statement shortly after the mistrial declaration.
Experts in maternal mental health emphasize the case's significance. Dr. Emily Carter, a psychiatrist specializing in postpartum disorders, noted, "This case highlights the urgent need for improved understanding and support for maternal mental health issues within the legal system." The Psychiatric Times has detailed challenges when postpartum psychosis defenses arise in criminal courts.
This case draws national attention to the intersection of postpartum mental illness and criminal justice, raising complex legal questions about evaluating severe mental health conditions during trials and appeals.
By the numbers:
- 7 days — Length of jury deliberations before mistrial.
- September 4, 2026 — Date mistrial declared by Judge Sullivan.
- January 24, 2023 — Date of the killings involving Lindsay Clancy.
Yes, but: The mistrial leaves uncertain whether mental health defenses like postpartum psychosis can be effectively adjudicated in criminal trials, raising potential for future appeals or retrials.
What's next: The prosecution and defense will decide on whether to seek a retrial or negotiate a plea, while broader discussions on legal reforms addressing maternal mental health defenses are expected to continue.
