The foreperson of the Clancy jury stated that the lone holdout juror eventually acknowledged having reasonable doubt about criminal responsibility, but then refused to vote for a not-guilty-by-reason-of-insanity verdict. The foreperson said she began filling out verdict forms believing they had reached a decision, but the holdout told the group: 'But I'm still not going to say that she's not guilty by reason of insanity.'
Jurors admitted that nurses serving on the panel used their own medical knowledge to help interpret toxicology evidence during deliberations. When the holdout juror asked a question about medications, the nurses referred to the toxicology report from South Shore Hospital and explained the amounts. One juror stated the holdout 'completely disregarded' the information the nurses provided.
The jury foreperson wrote a note to Judge William Sullivan expressing concerns about the holdout juror during deliberations. The defense attorney Kevin Reddington requested that the juror be removed, arguing the note indicated the juror refused to follow the judge's instructions on reasonable doubt. Judge Sullivan declined to remove the juror.
Judge William Sullivan declared a mistrial on September 4 in the Lindsay Clancy murder case after the jury spent more than six days deliberating and remained deadlocked 11-1. Clancy was charged with killing her three children in January 2023 and pleaded not guilty by reason of insanity, arguing she was suffering from postpartum psychosis.
Lindsay Clancy killed her three young children—Cora (5 years old), Dawson (3 years old), and Callan (8 months old)—at the family's home in Massachusetts in January 2023. After killing her children, Clancy attempted suicide by jumping from a second-story window and survived but was left paralyzed.
Jurors reported that the holdout juror would not interact with the trial exhibit cart and did not sufficiently engage with the panel. The jurors also revealed they rejected the holdout's suggestion to ask the judge to explain the concept of reasonable doubt again, with one juror recalling: 'And we were like, No, we have it in front of us. We don't need that.'
The three jurors who broke their silence reported that disagreements during deliberations became so intense that the six alternate jurors could hear them and believed the panel was fighting. Despite the conflict, the jurors said they were determined to continue deliberating and reach a verdict.
Jurors offered criticism of the prosecution's presentation of the case. One juror said she found it 'harsh—very, very harsh.' Another questioned why prosecutors had not presented character witnesses regarding whether Clancy was a bad mother, saying 'I found it to be biased.' The foreperson stated that evidence showed Clancy loved her children.
One juror stated that the holdout juror repeatedly returned to the fact that Clancy had killed her children, saying 'He had the hardest time getting off the fact that Lindsay viciously killed her children.' The other jurors tried to focus on the legal question of criminal responsibility, which was the actual case issue.
