Story summary
A Massachusetts mother, Lindsay Clancy, is on trial for allegedly murdering her three young children, Cora (5), Dawson (3), and Callan (8 months). Prosecutors claim that Clancy planned the murders and faked a suicide attempt afterwards. The defense, however, argues that Clancy should not be held criminally responsible due to her mental state at the time of the killings. They cite her diagnosis with bipolar disorder and postpartum psychosis, which they say caused extreme mood swings, delusions, and confusion.
Clancy's mother, Paula Musgrove, testified that her daughter had expressed thoughts of harming the children and felt overwhelmed by medication for postpartum depression. A psychologist, Dr. Paul Zeizel, met with Clancy in the hospital after the killings and reported that she heard a male voice ordering her to kill her children.
The trial has seen 15 days of testimony so far, with the defense calling several witnesses, including Clancy's mother and a forensic psychologist. The prosecution has presented evidence that Clancy planned the murders and faked a suicide attempt. Closing arguments are expected early next week. If convicted, Clancy faces life in prison without parole.
