The murder trial of Lindsay Clancy, the Massachusetts mother accused of killing her three children in 2023, has ended in a mistrial. After seven days of deliberations spanning more than 36 hours, the jury remained deadlocked on whether Clancy was criminally responsible for the deaths of her children.
Judge William F. Sullivan declared the mistrial on Friday, September 4, 2026, after the jury sent a third note indicating they could not reach a unanimous decision. However, in an unusual last-minute move, the judge granted defense attorney Kevin Reddington a one-hour delay to file an emergency appeal with the Massachusetts Supreme Judicial Court.
What Happened in Court?
The courtroom drama unfolded on Friday morning when the jury, which had been deliberating since 9 a.m., sent a note to the judge at approximately 11 a.m. stating they remained deadlocked and could not reach a verdict “with a heavy heart.”
Before this final note, tensions had already been running high. Defense attorney Reddington had clashed with the judge over the handling of a holdout juror. Reddington had requested that the judge question or remove the juror, accusing them of refusing to follow the court’s instructions on reasonable doubt.
According to Reddington, the jury foreperson had sent a note on Thursday claiming that one juror “has made statements acknowledging doubt but refuses to apply it to the verdict as the law states.” Reddington went further, accusing the holdout juror of lying during individual questioning.
Judge Sullivan repeatedly denied Reddington’s requests to remove the juror. “I don’t feel it is proper for me to side with one side or the other of the deliberations,” Sullivan said. He added that he had previously asked the jurors if they could follow his instructions and “they swore earlier that they could.”
The judge also became frustrated with Reddington’s demands for a more forceful instruction. At one point, Reddington called the judge’s approach “soft,” to which Sullivan responded: “What do you want me to do, get a brass band? I read the instruction as written by the [Massachusetts Supreme Judicial Court]. The fact that I perhaps didn’t give it my full inflection, I’m sorry about that.”
Why Was a Mistrial Declared?
In U.S. criminal trials, jury unanimity is required for a conviction. When a jury cannot reach a unanimous verdict after extensive deliberation, the judge may declare a mistrial due to a “hung jury” or “deadlocked jury.”
The jury had previously sent two notes indicating they were deadlocked. Sullivan had sent them back to deliberate, instructing them not to abandon their convictions but to seriously consider opposing views.
When the third note arrived on Friday, Sullivan stated: “I do not feel I have any choice but to declare a mistrial.”
What Does “Mistrial” Mean?
A mistrial does not mean:
- Acquittal
- Conviction
- The charges automatically disappear
- The defendant is legally declared innocent
A mistrial means the current trial ended without the required verdict. It is a procedural outcome that allows the legal process to continue in another form.
The Defense’s One-Hour Delay Request
Moments after Sullivan announced his intention to declare a mistrial, Reddington requested time to file an emergency appeal. The appeal reportedly involved the Americans with Disabilities Act, arguing that a juror had taken a position that was intractable regardless of proof beyond reasonable doubt.
Sullivan expressed frustration at the prospect of bringing the jury back but ultimately granted Reddington one hour to file an emergency motion with the Massachusetts Supreme Judicial Court. The mistrial was effectively placed on hold during this period.
Who Is Lindsay Clancy?
Lindsay Clancy is a 36-year-old former labor and delivery nurse from Duxbury, Massachusetts. She has been paralyzed from the waist down after jumping from a second-floor window following the deaths of her children.
Clancy admitted to strangling her three children in the basement of their family home on January 24, 2023. Her defense team, led by attorney Kevin Reddington, argued that she was not criminally responsible because she was suffering from postpartum psychosis and was overmedicated.
What Are the Charges Against Lindsay Clancy?
| Charge | Status |
|---|---|
| First-degree murder (Cora Clancy, age 5) | Mistrial |
| First-degree murder (Dawson Clancy, age 3) | Mistrial |
| First-degree murder (Callan Clancy, 8 months) | Mistrial |
Clancy pleaded not guilty to all charges. The jury was tasked with choosing from five possible verdicts: not guilty by reason of insanity, not guilty, first-degree murder, second-degree murder, or manslaughter.
What Happened to the Clancy Children?
Lindsay Clancy’s children were 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan. On January 24, 2023, Clancy strangled them with exercise bands in the basement of the family’s Duxbury home. She then jumped from a second-floor window, resulting in her paralysis.
Her husband, Patrick Clancy, had been sent out to get takeout food and medication. When he returned and found his wife outside in the snow, he made an anguished 911 call. After checking the basement, he can be heard howling and crying, telling the dispatcher: “She killed the kids!”
Patrick Clancy has since divorced Lindsay but has publicly stated that he forgives her, viewing her as ill rather than evil.
Prosecution’s Case
Prosecutors argued that Clancy planned the killings and knew right from wrong when she strangled her children. They pointed to evidence that she deliberately sent her husband on errands to get him out of the house.
Medical experts hired by the prosecution reached a different conclusion than the defense’s experts about Clancy’s psychiatric state at the time of the killings.
Prosecutors also questioned the seriousness of Clancy’s suicide attempt, arguing it could have been a calculated effort to avoid responsibility.
Defense’s Case
The defense admitted that Clancy killed her children but argued she should not be held criminally responsible because she was suffering from postpartum psychosis and was overmedicated.
Clancy’s mother, mother-in-law, sister, friends, and co-workers testified about her declining mental health in the months before the killings. She had seen multiple doctors, checked herself into a psychiatric hospital, and expressed feelings of hopelessness.
In October 2022, Clancy sent a text to her mother that read: “Mom, will you please come up and stay with me for a bit? I’m really sick. Something is wrong. I had horrible insomnia all night, and I just don’t know how I am going to get through the day. … It’s just really scary, and I don’t want to be alone.”
Clancy’s attorney argued that she was misdiagnosed and overmedicated, with psychiatrists relying on 25-minute video appointments.
Dr. Paul Zeizel, a clinical and forensic psychologist who visited Clancy after the killings, testified that he overheard her saying a disembodied male voice had told her she had no choice but to kill her children and then herself.
What Happens After a Hung Jury?
When a jury fails to reach a verdict, the following steps generally occur:
- Judge declares a mistrial — The current trial ends without a verdict.
- Prosecutors decide whether to retry — The prosecution can refile charges and start a new trial, negotiate a plea agreement, or dismiss the charges entirely.
- Defendant remains in custody or facility — Clancy is expected to remain at Tewkesbury Hospital, a psychiatric facility where she has been held for three years, to await the next steps.
In serious felony cases, prosecutors almost always ask for a retrial. If a new trial is scheduled, the jury selection process will begin again.
