Lindsay Clancy Murder Trial Ends in Mistrial After 11-1 Jury Split
By Drooid · · How we work
Core Event
On September 4 2026, Judge William Sullivan declared a mistrial in the Plymouth Superior Court case of Lindsay Clancy, a 36-year-old former labor-and-delivery nurse charged with three counts of first-degree murder for the deaths of her children—Cora, Dawson and infant Callan (8 months). The twelve-person jury was deadlocked after 38 hours of deliberation over seven days, with an 11-1 split favoring a verdict of not guilty by reason of insanity and a single holdout juror refusing to join the majority.
Background & Context
Clancy admitted on January 24 2023 that she strangled the three children with exercise bands in the basement of the family home in Duxbury, Massachusetts, and then attempted suicide, leaving her partially paralyzed. Her defense argued she was experiencing postpartum psychosis, a rare psychiatric emergency that can produce hallucinations and a loss of reality, and therefore lacked the mental capacity to understand or control her actions. The prosecution contended that Clancy planned the killings, citing her decision to send husband Patrick Clancy away to fetch medication and her ability to perform routine tasks before the murders.
The trial began with jury selection on July 20 and proceeded for six weeks, featuring testimony from six forensic experts who agreed Clancy suffered a serious mental illness, though they differed on the specific diagnosis.
Data & Statistics
- Victims: Cora, Dawson, Callan (8 months)
- Deliberation time: ~38 hours across seven days

Official Statements & Responses
- Timothy Cruz, Plymouth County District Attorney, said after the mistrial, “I appreciate the fact that there are strong feelings and opinions tied to this case.”
- Kevin Reddington, Clancy’s defense attorney, filed a motion asking the court to enter a required finding of not guilty, arguing that “no rational jury could find beyond a reasonable doubt that she had no mental disease or defect when the Commonwealth’s own proof established that she did.”
On-the-Ground Reports
Jurors who spoke publicly described the holdout juror’s conduct as obstructive, noting that he “admitted he had reasonable doubt” yet refused to apply it.
Criticism & Opposition
Legal analyst Heather Cucolo observed that “an 11-1 split for the defense is a strong indication that the prosecution’s central argument did not resonate with the vast majority of jurors.”
Conflicting Reports & Gaps
- Some media identified the holdout juror as a Black male, while other outlets said the juror’s identity remains sealed.
- Expert testimony diverged on Clancy’s diagnosis: defense psychiatrists emphasized postpartum psychosis, whereas prosecution experts highlighted a major depressive episode and bipolar II features.
