The Lindsay Clancy murder trial in Massachusetts is examining one of the most difficult questions in the case: was Clancy legally responsible for killing her three children, or was she in the grip of severe mental illness? Clancy is accused of killing her children, five-year-old Cora, three-year-old Dawson and eight-month-old Callan, in January 2023. She does not deny the killings, but her defence argues that she was suffering from bipolar disorder and postpartum psychosis at the time. NDTV’s Apurva Adhikari gets you the details.
