Quick Summary

Judge William Sullivan declared a mistrial in Lindsay Clancy's murder trial on Friday after an emergency appeal by the defense was denied. The jury had been deliberating for seven days and was unable to reach a unanimous decision, having stated three times that they were deadlocked. A second trial is possible, but the prosecution has not made any immediate decisions about next steps. This mistrial brings to a close a highly publicized case in which Clancy's defense team argued she was not criminally responsible due to mental health conditions, including bipolar disorder and postpartum psychosis.

Story summary

As of September 2026, Lindsay Clancy's murder trial in Duxbury, Massachusetts ended in a mistrial after five weeks due to a hung jury. The case involves the deaths of Clancy’s three young children—5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan—in January 2023. Clancy did not testify but admitted to killing her children while arguing she was suffering from postpartum psychosis at the time. The prosecution presented over 70 witnesses, including an FBI psychiatrist who testified that he does not believe Clancy heard a voice ordering her actions, suggesting she had control over her decisions.

The defense highlighted systemic failures in mental health support and rallied public sympathy by highlighting the challenges new mothers face when seeking help. However, one juror’s alleged misconduct prompted Clancy's attorney to ask Judge William Sullivan to investigate his phone use during deliberations and review a questionnaire he filled out prior to the trial. The judge is now considering whether Desronvil shared information or used his phone improperly during jury deliberation hours, which lasted seven days without reaching a verdict.
