Who did what, when and where: A 12-member jury in Plymouth County, Massachusetts, failed to reach a unanimous verdict on September 4, 2026, in the trial of Lindsay Clancy the 36-year-old mother accused of killing her three children on January 24, and Judge William Sullivan declared a mistrial.
Why it matters: The case has drawn national attention to questions about postpartum psychosis criminal responsibility, and how the legal system balances mental-health defenses with charges of homicide. The mistrial leaves open whether the Plymouth County District Attorney’s Office will pursue a retrial, and it continues to affect the victims’ community, the defendant’s family, and public debate.
Jury deliberations and declaration of mistrial
The jury deliberated for nearly 40 hours across seven days after five weeks of testimony before informing Judge William Sullivan that it could not reach a unanimous decision. The panel reported an 11-1 split and submitted a note stating, “It is with a heavy heart that we report we are unable to come to a unanimous decision, and we will not be able to.” Judge Sullivan accepted the note and declared a mistrial, ending the current trial phase without a verdict on the charges connected to the deaths of Cora, Dawson, and Callan on January 24.
Positions of defense and prosecution
The defense argued that Clancy was suffering from severe postpartum psychosis at the time of the killings and thus lacked criminal responsibility. Defense attorney Kevin Reddington expressed disappointment with the mistrial and criticized the holdout juror, saying, “They know that they were robbed by one [juror] for whatever [their] agenda was,” and later suggested the prosecution should rethink retrying the case by saying, “If I was Tim Cruz, I would probably say I don’t think I want to do a retrial because he’s going to lose.”
The prosecution, led by Plymouth County District Attorney Tim Cruz maintained that evidence showed Clancy acted with intent and control. Cruz said, “This was and has always been about getting justice for those three little babies,” and praised assistant district attorneys Jennifer Sprague and Shanan Buckingham for their work on the case. The prosecution presented expert testimony aimed at undermining the claim that psychosis rendered Clancy unable to form criminal intent.
Evidence and witness testimony presented at trial
Over several weeks, the court heard testimony from forensic psychiatrists and other witnesses about Clancy’s mental state in the period leading up to and on January 24. The defense presented testimony that Clancy heard a voice directing her to kill, supporting an argument of severe, acute postpartum psychosis. The prosecution countered with experts who testified that such symptoms would make the alleged single auditory command unusual, and they highlighted actions the state argued demonstrated planning and control.
With the mistrial declared, the decision whether to retry Clancy now rests with the Plymouth County District Attorney’s Office. Clancy will remain at the Tewksbury state hospital pending further legal proceedings. The case has generated national commentary, including from former President Donald Trump who called the events a “horrible tragedy” and stated, “There’ll be a price. It’s going to be a mental institution or jail or something,” reflecting the polarizing public debate around the appropriate legal and medical responses.
Defense attorney Kevin Reddington thanked jurors who deliberated and emphasized his client’s resilience, while prosecutors said they would weigh the evidence and legal options. The outcome keeps central the unresolved questions about accountability, the treatment of maternal mental health in criminal law, and what path the Plymouth County justice system will take next.
