A mistrial was declared in the Lindsay Clancy murder case after a jury in Plymouth, Massachusetts, became deadlocked following approximately 40 hours of deliberation over six and a half days. Three jurors, including the foreperson, have spoken publicly about the deadlock, stating that a single juror prevented a unanimous verdict.

According to interviews with NBC10 Boston, one juror acknowledged having reasonable doubt but ultimately refused to find Clancy not guilty by reason of insanity. Clancy, who is accused of killing her three young children in January 2023, admitted to the killings but entered a plea of not guilty by reason of insanity. Her defense argued that she was suffering from severe mental illness at the time of the deaths, while prosecutors contended she was criminally responsible.

The foreperson told NBC10 Boston that the holdout juror initially indicated reasonable doubt, leading the foreperson to believe a verdict was imminent. "But I'm still not going to say that she's not guilty by reason of insanity," the juror reportedly added. The foreperson also stated that she had communicated concerns to the judge about a juror who expressed reasonable doubt but would not agree to a verdict. The three jurors interviewed expressed frustration with the holdout, claiming he did not consider the perspectives of the other panel members.

NBC10 Boston reported attempts to contact the juror identified as the holdout were unsuccessful.

A judge officially declared the mistrial after the jury informed the court that they were hopelessly deadlocked. It remains unclear whether prosecutors will pursue a retrial in the case.
