Clancy Juror Breaks Silence — Bombshell Claim Rocks the Case
Jurors Wept as Lindsay Clancy Trial Ended in Mistrial — New Interviews Confirm an 11-1 Split, but the Holdout Has Not Spoken
Several jurors appeared visibly shaken when Lindsay Clancy's murder trial ended in a mistrial on September 4, 2026, after seven days of deliberations and more than 38 hours behind closed doors. The emotional reaction was documented by reporters inside Plymouth County Superior Court: one woman bent forward with her face in her hands, another wiped away tears and others appeared tense or distraught as Judge William Sullivan told the panel the case was over without a verdict. At the time, defense attorney Kevin Reddington said the jury had been split 11-1 in favor of finding Clancy not criminally responsible for killing her three children. That claim is now substantially stronger than it was on mistrial day. In post-trial interviews, the jury foreperson and two other jurors said 11 members favored acquittal on the basis of lack of criminal responsibility and that one male juror refused to join them. They also alleged that the holdout acknowledged having reasonable doubt but still would not vote for acquittal. The holdout juror has not publicly given his own account, however, and the judge never polled the panel in open court on each juror's preferred verdict before declaring the mistrial.
1. The Trial Ended Without a Verdict on September 4
Clancy, a 36-year-old former labor and delivery nurse, was tried in Plymouth County Superior Court on charges arising from the January 24, 2023 deaths of her three children - 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan - at the family's home in Duxbury, Massachusetts.
There was no factual dispute at trial that Clancy killed the children by strangling them with exercise bands. The central question was whether the Commonwealth proved beyond a reasonable doubt that she was criminally responsible when she did so.
The defense argued that Clancy was suffering from postpartum psychosis and a profound psychiatric breakdown that left her unable to appreciate the wrongfulness of her actions or conform her conduct to the law. Prosecutors argued that she was depressed and anxious but not psychotic, and that her conduct showed planning, awareness and deliberate action.
After more than five weeks of trial and 21 days of testimony, the jury began deliberating on August 27. It ultimately sent three notes saying it could not reach a unanimous decision. On September 4, Sullivan declared a mistrial.
2. The Jury Deliberated for Seven Days and More Than 38 Hours
The panel consisted of nine women and three men. Jurors considered a trial record that included more than 80 witnesses and hundreds of exhibits.
They repeatedly told Sullivan they were deadlocked. The judge sent them back to continue deliberating and eventually gave a supplemental instruction used in Massachusetts when a jury reports that it is unable to agree.
The instruction urged jurors to reconsider their views with respect for one another's reasoning, while emphasizing that no juror should surrender an honestly held conviction simply to produce a verdict.
By Friday, September 4, the foreperson's final note said it was with a 'heavy heart' that the jury remained unable to reach a unanimous decision. The court then moved toward a mistrial.
3. Reporters Saw Multiple Jurors Become Visibly Emotional
The emotional reaction in the courtroom was independently described by more than one television news organization.
CNN correspondent Jean Casarez reported that a producer inside the courtroom saw one female juror shake her head no when Sullivan told the jurors he was proud of them. Another woman clenched her hands into fists, while another kept her eyes closed and looked down as the judge explained the final decision.
WBZ-TV reporter Kristina Rex described an especially distraught female juror who bent forward, put her face in her hands and shook her head after Sullivan announced the mistrial. Rex said another woman wiped away tears and a third appeared to be holding back tears.
Those observations do not reveal why each juror was upset. But they do establish that the mistrial was not received by the panel as an emotionally neutral procedural ending.
4. The 11-1 Split Is No Longer Just the Defense Attorney's Claim
On mistrial day, Reddington publicly said that 11 jurors had been prepared to find Clancy not criminally responsible and that a single male juror prevented unanimity.
At first, that assessment had to be treated cautiously because the jury had not been individually polled in open court on its preferred outcome. A note from the foreperson established that there was one holdout, but not every juror's precise vote was placed formally on the public record.
Post-trial interviews have now provided stronger confirmation. The jury foreperson, Ronni Carlson, and two other jurors told NBC10 Boston that the jury was divided 11-1, with 11 favoring acquittal based on lack of criminal responsibility.
CBS Boston separately interviewed Juror No. 5, who also described an 11-1 divide. The post-trial accounts therefore make the numerical split far more firmly established than it was at the moment Sullivan declared the mistrial.
5. Jurors Say the Holdout Admitted Reasonable Doubt but Still Would Not Acquit
The most contentious new detail comes from the jurors' descriptions of the lone holdout.
Carlson told NBC10 that at one point she believed the group had finally reached unanimity because the holdout acknowledged that he had reasonable doubt. She said she began completing the verdict forms, only for him to state that he still would not find Clancy not guilty by reason of insanity.
Juror Paula Devlin described the holdout as unwilling to seriously accept the other jurors' reasoning. Other jurors similarly said he resisted applying the reasonable-doubt standard as they understood the judge's instructions.
That account is important but must be attributed carefully. The holdout juror's name remains under seal and he has not publicly responded. The statements now available describe what other jurors say occurred inside deliberations; they are not a judicial finding that he committed misconduct.
6. The Foreperson Raised the Holdout Problem Before the Mistrial
The dispute did not emerge only after the trial ended. During the sixth day of deliberations, the foreperson sent Sullivan a note raising concerns that a single juror was not properly applying the court's instruction on reasonable doubt.
Reddington seized on the note and asked Sullivan to investigate further or remove the juror. He argued that a juror who refused to follow the law should not be permitted to force a mistrial.
Sullivan declined to remove the juror. Rather than intrude further into the substance of deliberations, he re-instructed the full panel on reasonable doubt and asked whether jurors could continue following the law.
That decision reflected a core concern in jury law: judges must respond to genuine misconduct, but they also must avoid coercing a minority juror merely because the majority strongly disagrees with him.
7. The Defense Made a Last-Minute Appeal to Massachusetts' Highest Court
When Sullivan indicated on September 4 that he intended to declare a mistrial, the defense asked for a brief delay so it could seek emergency intervention from the Massachusetts Supreme Judicial Court.
Defense attorney Dana Goldblatt argued to a single justice that the trial judge should conduct additional inquiry into the holdout juror's behavior rather than terminate the case.
Justice Dalila Argaez Wendlandt declined to intervene. After the emergency request was denied, Sullivan brought the jury back into the courtroom at about 2:22 p.m. and formally declared the mistrial.
The SJC's refusal to intervene did not determine that the holdout juror's conduct was proper in every respect. It meant the defense did not obtain the extraordinary emergency relief needed to stop the trial judge from ending a hopelessly deadlocked proceeding.
8. The Case Turned Almost Entirely on Clancy's Mental State
The prosecution and defense agreed on the physical acts but offered sharply different explanations of Clancy's mind.
The defense presented expert testimony and medical evidence to argue that her mental health deteriorated dramatically after the birth of Callan and that she was psychotic when she killed the children.
Prosecutors emphasized evidence they said showed purposeful conduct. They argued that Clancy arranged for her husband, Patrick, to leave the house to pick up medication and food, creating an opportunity to be alone with the children, and that the sequence of events demonstrated awareness rather than a complete break with reality.
Under Massachusetts law, once criminal responsibility is properly in issue, the Commonwealth bears the burden of proving beyond a reasonable doubt that the defendant was criminally responsible.
9. An Acquittal on Criminal Responsibility Would Not Necessarily Have Meant Immediate Release
The phrase 'not guilty by reason of insanity' is often misunderstood as equivalent to immediate freedom. That would not necessarily have happened in Clancy's case.
If jurors had unanimously found that the Commonwealth failed to prove criminal responsibility, the court could have ordered Clancy evaluated and committed to a psychiatric facility if she met the legal standards for continued confinement.
By contrast, a first-degree murder conviction could have exposed her to life imprisonment without parole. The jury also had lesser homicide options available under the judge's instructions.
The deadlock therefore concerned not simply whether Clancy committed the acts, but the legal consequences of her mental condition at the precise time she committed them.
10. The Jurors' Post-Trial Accounts Explain the Visible Distress
The post-trial interviews provide context for the emotional scene described by CNN and WBZ when the mistrial was announced.
Jurors said they spent days reviewing medical testimony, journals, family evidence, toxicology information and the 911 call made by Patrick Clancy after he discovered the children. One juror told the Associated Press that playing the 911 recording again during deliberations caused members of the panel to cry.
The foreperson said evidence about Clancy's relationship with her children convinced her that Clancy had loved them and had undergone a catastrophic break from her normal state of mind. Other jurors described the case as emotionally overwhelming.
Those comments illuminate why several jurors appeared devastated by an ending that required them to leave without a verdict after weeks of testimony and a week of deliberations.
11. Prosecutors Have Not Yet Announced Whether They Will Retry the Case
A hung-jury mistrial generally permits prosecutors to retry a defendant because the first jury never reached a final verdict. The Double Jeopardy Clause does not ordinarily bar a new trial after a genuinely deadlocked jury.
Plymouth County District Attorney Timothy Cruz said after the mistrial that prosecutors had not yet made a decision about whether to try Clancy again.
A second trial is one possibility. A negotiated plea is another. Reddington has publicly said he is open to discussing a plea agreement, while also signaling that the defense may continue challenging the legal consequences of the first trial.
Clancy's next scheduled court appearance is September 29, when the parties are expected to address how the case will proceed.
12. Clancy Remains at Tewksbury Hospital
Clancy remains in state custody at Tewksbury Hospital, where she has been receiving psychiatric and medical care.
After killing the children, she jumped from an upstairs window in an apparent suicide attempt. She survived but suffered severe spinal injuries and is now paralyzed.
The criminal charges remain pending despite the mistrial. A mistrial does not amount to an acquittal, a conviction or a dismissal of the case.
13. What Can Be Said With Confidence
Judge William Sullivan declared a mistrial in Lindsay Clancy's murder case on September 4, 2026 after a 12-person jury failed to reach a unanimous verdict following seven days and more than 38 hours of deliberations.
The jury consisted of nine women and three men and sent the court three notes stating that it could not agree.
Multiple reporters inside the courtroom described female jurors crying, shaking their heads, covering their faces or otherwise appearing visibly distressed when the mistrial was announced.
The foreperson's communications established that a single juror was blocking unanimity. Post-trial interviews with the foreperson and other jurors now confirm an 11-1 split in favor of finding Clancy not criminally responsible.
Those jurors say the holdout acknowledged reasonable doubt but still refused to vote for acquittal. The holdout has not publicly given his own account, and the judge did not issue a finding that he committed juror misconduct.
Sullivan declined the defense request to remove or individually investigate the holdout and instead re-instructed the jury on reasonable doubt. A single justice of the Massachusetts Supreme Judicial Court declined an emergency defense request to halt the mistrial.
The central question at trial was Clancy's criminal responsibility, not whether she physically killed her children. The defense argued postpartum psychosis; prosecutors argued she understood and deliberately planned her conduct.

The mistrial leaves the charges unresolved. Prosecutors have not yet announced whether they will seek a retrial, and the case is scheduled to return to court on September 29.
The strongest accurate version of the story is therefore more precise than the first reports: the jury was not simply vaguely deadlocked. Eleven jurors have now been publicly described, by multiple members of the panel, as favoring an insanity-based acquittal, while a single holdout prevented unanimity. But because that holdout has not spoken and no verdict was entered, the case remains legally open.
