Quick Summary

A mistrial has been declared in the trial of Lindsay Clancy, a Massachusetts mother accused of killing her three young children. After a week of deliberations, the 12-person jury remained deadlocked with 11 jurors voting for conviction and one against. The judge declared a mistrial after defense attorney Kevin Reddington requested an emergency stay to question a juror who allegedly displayed bias and refused to follow court instructions on reasonable doubt. The Massachusetts supreme judicial court denied the request, allowing the mistrial to be declared.

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.
