Lindsay Clancy appeared in a Massachusetts courtroom Monday as her defence sought to dismiss the triple-murder case against her, leaving the prospect of a second trial unresolved.
The hearing in Plymouth Superior Court on November 2, 2026, centred on whether prosecutors may continue pursuing charges after Clancy’s first trial ended in a mistrial when jurors could not reach a unanimous verdict.
No ruling on the dismissal request had been reported as of the newsroom’s 11 a.m. Eastern update.

Lindsay Clancy defence challenges possible retrial
Clancy’s lawyers argue that holding another trial would violate the constitutional protection against double jeopardy.
Their position is that the mistrial was declared without the level of necessity required to justify putting her through a second prosecution.
The defence has focused part of that argument on the jury’s lone holdout, who favoured a murder conviction while the other 11 jurors were reported to be prepared to find Clancy not criminally responsible because of mental illness.
Defence lawyers say the judge should have investigated whether the holdout juror was following the court’s instructions before ending the trial.
Judge William Sullivan previously rejected a request for an evidentiary hearing into the juror, saying courts must avoid examining jurors’ private reasoning and deliberations.
The defence continues to argue that information about the juror is relevant to its dismissal motion.
Prosecutors say the case can continue
Plymouth County prosecutors have asked the judge to reject the dismissal application.
They argue that the jury was genuinely deadlocked after extended deliberations and that the mistrial was therefore properly declared.
In a filing opposing dismissal, prosecutors said the Commonwealth should be permitted to continue seeking justice for Cora, Dawson and Callan Clancy.
The filing indicates that prosecutors are preserving the option of a retrial, although District Attorney Timothy Cruz has not publicly committed to a specific new trial date or confirmed all details of how the case would proceed.
A retrial could involve the same first-degree murder charges, lesser charges or another prosecutorial decision after the court rules on the outstanding motions.
The final path remains dependent on Judge Sullivan’s decisions and the district attorney’s office.
Gag-order request also before the judge
The court is also considering a prosecution request for restrictions on public statements by lawyers, prosecutors and law enforcement personnel connected with the case.
Prosecutors say limits are needed to protect the fairness of any future jury proceeding after the first trial generated extensive public attention and frequent commentary outside court.
Clancy’s lawyers oppose the request, calling it an unconstitutional prior restraint on speech.
They argue that prosecutors have not shown an immediate threat to a future jury because there is not yet a new trial date or even a final decision that the case will be retried.
What happened at the first trial
Clancy pleaded not guilty to charges connected with the deaths of her three children at the family’s Duxbury home on January 24, 2023.
Cora was five, Dawson was three and Callan was eight months old.
Her defence did not dispute at trial that she caused the children’s deaths.
Instead, lawyers argued that she was not criminally responsible because she was suffering from postpartum psychosis and the effects of psychiatric medication.
Prosecutors argued that Clancy deliberately strangled the children and understood that her actions were wrong.
The jury deliberated for several days before reporting that it could not reach a unanimous verdict, leading Sullivan to declare a mistrial on September 4, 2026.
Clancy has remained in a state psychiatric hospital since the killings.
She also has significant physical disabilities after surviving a suicide attempt immediately following the deaths.
What comes next
The immediate next step is a ruling on the defence’s dismissal arguments and the other post-trial motions.
The judge may also address whether a trial date can be selected if the case remains active.
Until those decisions are made, Clancy remains charged but has not been convicted.
A mistrial is not a finding of guilt or innocence, and any future prosecution would begin with the presumption of innocence.
