Deadlocked Jury Leads to Mistrial
On September 4, 2026, Judge William Sullivan declared a mistrial after the 12-person jury reported it could not reach a unanimous verdict. The split was 11-1, with the majority leaning toward a not-guilty-by-reason-of-insanity finding.
Background & Context
Clancy, a 36-year-old former labor-and-delivery nurse, admitted on January 24, 2023 that she strangled her three children—Cora, Dawson and infant Callan (8 months)—with exercise bands in the basement of their Duxbury, Massachusetts home. She then cut herself and jumped from a second-story window, leaving her paralyzed. The trial centered on whether she acted with criminal intent or was driven by postpartum psychosis, a rare severe mental-health condition.

Why It Matters / Impact
The case is a flashpoint for postpartum mental-health policy and the insanity defense. Prosecutors argue the killings were pre-meditated; the defense maintains severe psychosis stripped Clancy of criminal responsibility. The deadlock shows how jurors grapple with complex medical testimony and moral judgments, influencing future prosecutions of mothers who kill their children.
Official Statements & Responses
Judge Sullivan warned that no alternative jury would necessarily reach a different conclusion and reaffirmed the standard of “reasonable doubt.” Defense attorney Kevin Reddington argued a retrial would re-expose the family to trauma and expressed confidence that the evidence supports mental incapacity.
Criticism & Opposition
Boston-based criminal-defense attorney Peter Elikann suggested the prosecution might consider plea negotiations to avoid a second, costly trial. Legal scholar Heather Ellis Cucolo noted the prosecution’s stance that public opinion will not dictate its decision, highlighting tension between community pressure and legal strategy.
Conflicting Reports & Gaps
Most outlets report an 11-1 split, but a few describe the deadlock only in general terms, leaving the precise juror count ambiguous. While the defense cites postpartum psychosis, the prosecution points to severe depression; the exact clinical determination remains unsettled, and no definitive psychiatric report has been released publicly.
Verbatim Quotes

- “At this point, I'm going to declare that the jury is deadlocked and I'm going to declare a mistrial,” — Judge William Sullivan

What’s Next
A status conference is set for September 29, when the court will hear whether Plymouth County District Attorney Timothy Cruz will seek a retrial on the first-degree murder charges, pursue lesser charges, or offer a plea deal. Clancy will remain in custody at Tewksbury State Hospital pending that decision.
