Lindsay Clancy's murder trial in Plymouth, Massachusetts, ended in a mistrial on September 4, 2026, after the 12-person jury could not reach a unanimous verdict. ^[1] Judge William F. Sullivan sent the deadlocked jury in the Lindsay Clancy trial home without a verdict on Thursday, September 3, 2026, following six days of deliberations in Plymouth, Massachusetts. ^[2] Judge William F. Sullivan declared a mistrial in the case of Lindsay Clancy on Friday after the jury failed to reach a unanimous verdict following approximately 38 hours of deliberations over seven days. ^[3] Lindsay Clancy, a former nurse, is accused of murdering her three children in their Duxbury, Massachusetts, home in January 2023. ^[4] Plymouth County District Attorney Timothy Cruz said on September 4, 2026, that the prosecution will decide whether to retry Lindsay Clancy at a future hearing, and that no decision has been made today. ^[5] Defense attorney Kevin Reddington sought to remove one juror after the jury foreperson reported in a note that the juror would not follow the judge's instructions about reasonable doubt. ^[6] Judge William F. Sullivan declined the request to remove the juror and ordered the jurors and alternates to return to the courtroom on Friday morning at 9 a.m. ^[7] Defense attorney Kevin Reddington requested a delay of the mistrial to allow a higher court to review concerns that a single juror revealed a possible bias against those dealing with mental illness. ^[8] Lindsay Clancy, a 36-year-old former labor and delivery nurse, never disputed that she killed her three children, including an 8-month-old, but her attorney argued she was suffering from postpartum psychosis in 2023. ^[9] The state's top court denied the defense attorney's appeal, and Judge William F. Sullivan formally declared a mistrial later in the afternoon. ^[10] Reddington stated that the foreperson identified the holdout juror to the judge and expressed hope that the trial would be resolved after the judge questions the juror on Friday. ^[11]
