The prosecution has already informed the court that it intends to retry Clancy, meaning the legal battle surrounding the deaths of her three young children is far from finished.
The dramatic conclusion followed hours of uncertainty after Clancy attorney Kevin Reddington made an emergency attempt to stop Sullivan from ending the case.
Sullivan initially announced that he was prepared to declare a mistrial after receiving yet another message indicating that the jury remained deadlocked. But before the judge could formally bring the proceedings to an end, the defense asked for time to seek intervention from the Massachusetts Supreme Judicial Court.
Sullivan gave the defense team one hour to pursue its emergency request.
The state’s highest court subsequently granted the defense a hearing, which was conducted by Zoom. The emergency relief sought by Clancy’s attorneys was ultimately denied.
With that avenue exhausted, Sullivan officially declared the mistrial.
Seven Days of Deliberations End Without a Verdict
The case stems from the January 2023 deaths of Clancy’s three children: 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan.
Clancy admitted to killing the children, but her attorneys argued that she should not be held criminally responsible because of her mental state at the time.
The defense maintained that Clancy was experiencing severe postpartum psychosis and heard voices directing her to kill her children.
Prosecutors presented a sharply different account.
They argued that Clancy’s actions were deliberate and premeditated, pointing in part to evidence that she sent her husband away on an errand before killing the children.
The 12-member jury — nine women and three men — was asked to consider several possible outcomes, ranging from first-degree murder to a finding that Clancy was not criminally responsible.
Jurors could choose guilty of first-degree murder, guilty of second-degree murder, guilty of manslaughter, not guilty, or not guilty because of a lack of criminal responsibility.
But after seven days behind closed doors, the panel remained unable to agree.
Defense Targets Alleged “Holdout” Juror
The tensions that had been building throughout deliberations exploded in open court as Clancy’s defense team focused its attention on one juror it believed was preventing the panel from reaching a verdict.
On Thursday, the defense sought to have one juror removed, arguing that the individual was failing to properly apply the legal standard involving reasonable doubt.
Sullivan refused.
The judge instead provided the jury with additional guidance concerning reasonable doubt and directed the panel to return to deliberations.
By Friday, however, the dispute had escalated.
Reddington accused one male juror — described as the lone “holdout” — of refusing to follow the law. The defense attorney went so far as to accuse the juror of lying under oath, arguing that the man had previously agreed to follow the court’s instructions but was allegedly refusing to apply the reasonable-doubt standard during deliberations.
Reddington then turned his criticism toward Sullivan.
The defense lawyer complained that the judge had failed to give jurors a sufficiently “forceful” explanation of the prosecution’s burden of proving its case beyond a reasonable doubt.
That criticism prompted a heated response from the bench.
“What do you want me to do, get a brass band?” Judge Sullivan asked Reddington. “I read the instruction as written!”
The exchange didn’t end there.
“I’m not an actor! I’m just giving the instruction!” the judge shouted.
Reddington continued pushing the issue, accusing Sullivan of “glossing” over the defense’s concerns about reasonable doubt.
Sullivan strongly rejected the accusation.
“I am not glossing over the issue. I’ve thought about this issue long enough,” the judge said.
The unusually combative exchange underscored just how contentious the final hours of the trial had become.
Emergency Court Fight Fails
Once the jury again indicated that it could not reach unanimity, Sullivan moved toward declaring a mistrial.
Reddington wasn’t ready to concede.
The defense made its emergency bid for intervention from the Massachusetts Supreme Judicial Court, temporarily putting the mistrial declaration on hold.
For a brief period, the fate of the trial shifted away from the Plymouth courtroom and into the hands of the state’s highest court.
The defense received a hearing, but its attempt to keep the proceedings alive ultimately failed.
At roughly 2:20 p.m. ET, the emergency request for relief was denied.
Sullivan then made the mistrial official.
The decision brings the first trial to an abrupt conclusion without resolving the central question that divided the jury: whether Clancy should be held criminally responsible for the deaths of her children.
That question will now apparently be put before another jury.
Prosecutors have already indicated that they plan to retry the case, setting the stage for another major courtroom battle over Clancy’s mental state, criminal responsibility and the deaths of Cora, Dawson and Callan.
WATCH:
After seven days of deliberations, repeated warnings from a deadlocked jury, accusations against an alleged holdout, a fiery attorney-judge confrontation and an emergency appeal to the state’s highest court, the first Clancy trial is officially over.
But the case itself is not.
