The News

Three jurors from Lindsay Clancy's triple-murder trial say one male holdout kept the panel from finding the Duxbury mother not guilty by reason of insanity — after he had already conceded he had reasonable doubt.

The three women, including the jury foreperson, described the deliberations in an interview with NBC10 Boston that aired Tuesday, four days after Judge William Sullivan declared a mistrial in Plymouth Superior Court.

The jury of nine women and three men deliberated more than 38 hours and told the court it was split 11-1.

The Moment It Collapsed

"He admitted he had reasonable doubt, and I started filling out the forms, I was so excited," the foreperson — identified only as Ronnie, a retired fifth-grade special needs teacher — told NBC10's Sue O'Connell. "There were three forms I had to fill out and I started filling them out, I wrote my signature on each one, and then he said, 'but I'm still not going to say that she's not guilty by reason of insanity.'"

Timeline

Jan. 24, 2023

Clancy, then a labor and delivery nurse, strangles her three children — Cora, 5, Dawson, 3, and 8-month-old Callan — in the basement of the family's Duxbury, Massachusetts, home after sending her husband out for takeout. She cuts herself and jumps from a second-story window.

Summer 2026

Clancy, 36, goes to trial. She admits killing the children; her attorney, Kevin Reddington, argues she is not criminally responsible because she was in the grip of postpartum psychosis and heard a voice telling her to kill her children and herself. Prosecutors argue she methodically planned the killings and understood they were wrong.

Sept. 4, 2026

After more than 38 hours of deliberation and notes to the court reporting an 11-1 split — with the majority at one point saying the holdout could not follow the law on reasonable doubt — Judge Sullivan declares a mistrial. He orders the jurors' names sealed from the public for two weeks.

Sept. 8, 2026

Three jurors sit for an interview with NBC10 Boston, describing a deliberation room that turned tense enough for the alternates to hear the arguing through a wall.

Reactions

"He was very arrogant," one of the jurors said of the holdout. "He really did not take anything that anybody said ... He just completely disregarded the information that they gave him." Jurors who are nurses had walked him through Clancy's toxicology report, she said.

A third juror, Paula, who has worked for government contractors, said she wasn't sure "rogue" was the right word for him. The panel read him the legal definition of reasonable doubt over and over, highlighted it and read it again, she said: "He would not interact with us and try to understand."

"He had the hardest time" letting go of the fact that "Lindsay viciously killed her children," she said.

The jurors also described leaning on each other through the ordeal. There were "hugs," "laughter" and "a lot of self-care and group care," O'Connell said of their account. NBC10 Boston said it tried to reach the holdout juror; he has not spoken publicly.

What's Next

The mistrial leaves the case unresolved and open to a retrial. No retrial date has been set in current reporting.

The jurors' names remain sealed for two weeks under Judge Sullivan's order, though the jurors themselves are free to speak publicly about the case and their deliberations — which is how Tuesday's interview happened.

More

The legal question that split the room was not whether Clancy killed her children — she admitted that — but whether her mental state at the time relieved her of criminal responsibility. Under the insanity defense her lawyer mounted, a single juror's refusal is enough to deny both an acquittal and a conviction.

The three jurors were identified in the interview only by first name and occupation: Ronnie, the retired teacher who served as foreperson; Kellie, a retired chef from Plymouth; and Paula, who has worked for government contractors.
