The essentials
Expert testimony concludes; conflicting psychiatric assessments define trial's final phase before jury decides verdict.
Lindsay Clancy's trial has entered its final witness phase in Plymouth Superior Court, with forensic psychologist Kirk Heilbrun and psychiatrist Avram Mack providing key testimony on her mental state. Heilbrun testified that Clancy reported hearing a voice only on the night of the killings, while Mack concluded that Clancy was depressed but not experiencing psychosis.
Judge William Sullivan denied a mistrial request citing prosecutors' mention of religion, allowing the case to proceed. The defense rested after calling psychiatrist Phillip Resnick, completing its case presentation.
If convicted on three counts of first-degree murder, Clancy faces life in prison without parole. The conflicting psychiatric testimony—with defense experts supporting a postpartum psychosis argument and prosecution experts questioning that diagnosis—has defined the trial's central dispute over her mental state at the time of the January 2023 deaths.
