Patrick Clancy said the possibility of another trial over the deaths of his three children would be extraordinarily painful for him and his family. Prosecutors must now decide whether to seek a retrial, while the court has scheduled a status hearing for Sept. 29.

Mistrial follows weeklong deliberations
The mistrial was declared Friday, Sept. 4, 2026, at Plymouth Superior Court in Plymouth, Massachusetts. Jurors had deliberated for approximately one week before informing Judge William Sullivan that they could not reach the unanimous verdict required to resolve the murder charges. The decision ended the trial without a verdict and left the next major step to prosecutors.
The proceedings drew supporters and onlookers outside the courthouse as they waited for a possible decision. The court’s declaration did not determine whether Lindsay Clancy was guilty or not guilty. Instead, it closed the current trial and created the possibility of a new proceeding.
Patrick Clancy responds to possible retrial
Patrick Clancy responded through his attorney, David Meier, after the mistrial. His statement thanked the court and jurors for their work and acknowledged the continuing impact of losing his children, 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan.
“The prospect of reliving this tragedy through another trial is extraordinarily painful, for Patrick, for his family, and for all us,” David Meier wrote in the statement.
The statement also said Patrick Clancy would never recover from the loss and would never have closure. He has previously asked the public to forgive his former wife, who has admitted killing the children.
The prosecution and defense positions
The case focused on whether Lindsay Clancy was legally responsible for the deaths and whether her mental state met the legal standard for insanity. Her attorneys argued that she was legally insane because of postpartum psychosis, a condition they said affected her at the time of the killings.
The reported jury split was 11-1, although the jurors’ deliberations were not publicly resolved through a verdict. Defense attorney Kevin Reddington argued that the lone holdout had acknowledged doubt but was not properly applying the court’s instructions concerning reasonable doubt. The defense sought additional review rather than an immediate mistrial.
What happened before the mistrial
During the trial, Patrick Clancy testified about Jan. 24, 2023, the day his children were killed. He said he had left the home to run errands, including picking up children’s stool softener at a CVS store and collecting takeout for dinner. He and Lindsay Clancy spoke by telephone while he was away.
The testimony formed part of the prosecution’s account of the events surrounding the children’s deaths. The defense presented its insanity argument through its broader case concerning Lindsay Clancy’s mental condition. The trial concluded with the jury unable to agree after hearing the evidence and the judge’s instructions.
Next court dates and legal options
Prosecutors now must decide whether to retry Lindsay Clancy. Judge Sullivan said he wanted the case retried “sooner rather than later,” raising the possibility of another trial later in the fall, although no new trial date had been set.
Lindsay Clancy is scheduled to return to court Sept. 29 for a status hearing, trial assignment and consideration of a defense Rule 25 motion. Before the mistrial was declared, Clancy’s attorneys made an emergency appeal to the Massachusetts Supreme Judicial Court seeking to stop the mistrial and require further inquiry into the juror dispute. Justice Dalila Argaez Wendlandt denied that request Friday afternoon, after which Judge Sullivan declared the mistrial.
