Quick Summary

A judge has declared a mistrial in the murder trial of Lindsay Clancy, who is accused of strangling her three children to death in January 2023 at their home south of Boston. The jury deadlocked after nearly six weeks of deliberation and seven days of deciding whether Ms. Clancy was criminally responsible for the killings amid conflicting testimony about her post-pregnancy mental health. Prosecutors argue that Ms. Clancy planned to kill her children, while her defense team claims she suffered from postpartum psychosis, which led to her actions. A mistrial means the case is cancelled and can be retried with a new jury if prosecutors choose to proceed.

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.
