Mistrial Declared in Lindsay Clancy Murder Trial
A Massachusetts judge declared a mistrial on Friday in the murder trial of Lindsay Clancy, a former labor and delivery nurse who admitted to strangling her three young children in 2023. The decision came after jurors sent a note for a third time stating they could not reach a unanimous verdict.
Judge William Sullivan of Plymouth County Superior Court ended the trial after the jury, deliberating for seven days following a nearly six-week trial, reported an 11-1 deadlock. The jury foreperson's note read: "It is with a heavy heart that we report we are unable to come to a unanimous decision and will not be able to."
The mistrial followed a dramatic turn in deliberations when the foreperson told the judge that a lone holdout juror was refusing to apply the court's instructions on reasonable doubt. The defense sought to have the juror removed or further questioned, but Judge Sullivan declined, citing legal precedent that "the discharge of a deliberating juror is a sensitive undertaking, fraught with potential error."
The defense then filed an emergency appeal with the Massachusetts Supreme Judicial Court, arguing that the juror's reasoning reflected bias against those with mental illness and that the refusal to follow the law was "not a matter of protected deliberative privilege." The appeal was denied after a brief hearing conducted via video conference, with Justice Dalila Argaez Wendlandt taking the matter under advisement before the denial.
Defense and Prosecution Arguments
Lindsay Clancy, 36, never denied killing her children—5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan—in the basement of their Duxbury home on Jan. 24, 2023. She was charged with three counts of first-degree murder and pleaded not guilty by reason of insanity.
Defense attorney Kevin Reddington argued that Clancy suffered from severe postpartum psychosis and bipolar disorder at the time of the killings, describing her condition as a mental health emergency. He blamed "lousy medical care" and the effects of medication, and told reporters that his client and her family were "Not good" after the mistrial. Reddington said he believed Clancy deserved an acquittal, and he criticized the holdout juror, saying, "They know that they were robbed by one man for whatever his agenda was, who stole seven weeks of the life of these other jurors."
Prosecutor Jennifer Sprague argued that Clancy knew what she was doing and intentionally planned the deaths, sending her husband on errands to carry out the killings. During the trial, forensic psychologist Kirk Heilbrun testified that Clancy did not have acute psychosis when she killed her children, concluding she acted because she wanted to take her own life but didn't want to leave them behind. In contrast, forensic psychiatrist Phillip Resnick testified that Clancy was "clearly psychotic" and not in control of her actions.
Clancy's former husband, Patrick, testified that she had shared intrusive thoughts of harming their children and heard a voice telling her to kill. Phone data showed searches for hallucinations, psychosis, and suicide in the weeks leading up to the killings, and a note on her phone read: "I'm terrified of something happening to my kids or doing something wrong to mess up their development."
Reactions and Next Steps
Plymouth County District Attorney Timothy J. Cruz said his office had not yet decided whether to pursue a second trial. "Children were murdered, and it's our job to seek justice," he said. "I appreciate the fact that there are strong feelings and opinions tied to this case. However, our job is to set aside our feelings and focus solely on the facts." Cruz said a decision would not be immediate and that the case was about getting justice for the three children.
Judge Sullivan ordered the names of the jurors impounded, citing significant and divisive attention, with the order set to expire in 14 days unless otherwise directed. A hearing is scheduled for Sept. 29, at which Reddington may ask Sullivan to declare Clancy not guilty, a motion that legal experts said was unlikely to succeed.
David Meier, representing Patrick Clancy in a separate civil lawsuit, released a statement expressing gratitude to the court and jurors, calling the prospect of another trial "extraordinarily painful." Lindsay and Patrick Clancy have filed separate lawsuits alleging that various healthcare providers failed her.
The case has drawn attention to maternal mental health. Jessie Colbert, coordinator of the Massachusetts Mind the Gap Coalition, called the killings "a preventable tragedy" and highlighted the ongoing crisis of Perinatal Mood and Anxiety Disorders. Allison Lespasio, a social worker, said the case has sparked a nationwide conversation on women's mental health after childbirth.
Clancy remains charged with murder and will continue to be held at a psychiatric hospital until her criminal case is resolved. President Trump commented on the case, calling the killing of children a "horrible tragedy" and saying there would be a price—"a mental institution or jail or something."
