A Massachusetts judge has refused Lindsay Clancy’s bid to question the holdout juror who forced a mistrial in her triple-murder case, keeping the path to a full verdict blocked for now.
ABC News reported that Judge William Sullivan on Wednesday denied the defense request to question that juror and barred any use of the Nov. 2 hearing to investigate the holdout.
Clancy still faces three murder charges in the Jan. 24, 2023, deaths of her children, 5-year-old Cora, 3-year-old Dawson, and infant son Callan, at the family’s home in Duxbury, a Boston suburb. She has pleaded not guilty.
After a seven-week trial this summer, the jury split 11-1 in favor of finding her not guilty by reason of insanity. Sullivan declared a mistrial when the panel could not reach a unanimous verdict.
The defense wanted an evidentiary hearing on claims the holdout, called Juror Doe in the judge’s writing, may have lied on the jury questionnaire about prior involvement with the criminal justice system, used a phone during deliberations, or failed to follow the judge’s instructions. Lawyers had also argued the indictment should be dismissed because the court failed to properly inquire about the holdout before the mistrial.
Sullivan shut that door. He concluded the defense had not shown it was entitled to an evidentiary hearing, and that potential evidence surfacing only after a mistrial is not relevant to whether there was a “manifest necessity”, the legal standard for declaring one.
In his written conclusions, Sullivan drew a hard line around what a court may examine after a hung jury.
Judge William Sullivan wrote:
“This Court concludes that any further judicial inquiry is inappropriate, given the mandate that the court must not delve into a juror's subjective reasoning, thought process, view of the case, or relationship to the other jurors, and must not inquire into the jury's deliberative content, collective thought process, or any disagreement among the jury,”
He also framed the defense’s aim directly.
Sullivan stated:
“It appears that Clancy seeks an evidentiary hearing to determine whether Juror Doe lied on the jury questionnaire about prior involvement with the criminal justice system,”
Then he closed the relevance gap.
The judge added:
“However, potential evidence of good cause to dismiss a deliberating juror that came to light only after a mistrial was declared simply is not relevant to whether there was a manifest necessity for a mistrial.”
Prosecutors and Clancy’s defense lawyers both declined to comment on the ruling. Clancy remains due in court Nov. 2. Sullivan has not issued a ruling on the related dismissal motions described in the reporting.
The core facts of the case are grim and undisputed in the charging posture. On the night her children died, Clancy attempted suicide and was left paralyzed and in a wheelchair. Prosecutors say she allegedly strangled the three children. The trial focused on whether she was suffering from postpartum psychosis, a severe psychiatric emergency after childbirth, as the American College of Obstetricians and Gynecologists has described the condition, and whether she should be held criminally liable.
That same case has already seen repeated judicial management fights, including when a judge denied a mistrial bid after a prosecution psychologist raised a “mortal sin” question a second time.
Clancy, a former nurse, appeared in Plymouth, Massachusetts, court on Sept. 29, 2026, as Sullivan listened to argument on a motion to dismiss. The defense has pressed hard on process, including a push that invoked double jeopardy to block a retrial after the 11-1 split.
Earlier, when the panel reported deadlock, the court ordered the Lindsay Clancy jury to keep deliberating rather than end the trial at the first sign of trouble. The latest order keeps the holdout off-limits for questioning.
Clancy’s lawyers have argued there is no proof she murdered her children and have sought dismissal on multiple fronts. One earlier defense claim held there was no proof Lindsay Clancy murdered her three children. The latest move, trying to put the holdout under oath after the mistrial, fit that pattern of challenging the trial’s integrity rather than waiting for a clean retrial.
Trial management has been tight before. The proceedings were once paused early after the judge barred a TikTok witness and cited an unforeseen circumstance. Sullivan’s newest order keeps the focus off post-mistrial juror forensics and on the calendar ahead.
What the court will not do is reopen the jury room’s private reasoning. What remains is the charge sheet, the dead children, the 11-1 split, and a Nov. 2 date. The defense wanted to litigate the holdout’s questionnaire answers, phone use, and compliance with instructions. The judge said that material, arriving after the mistrial, does not answer whether the mistrial itself was legally required.
Three young lives ended in a Duxbury home. A jury came one vote short of an insanity acquittal. The court has now refused to turn the holdout into a post-trial witness. Accountability for Cora, Dawson, and Callan still has to run through a verdict the system can finish, not through endless side fights over a single juror’s inner thoughts.
