A mental health nurse who treated Lindsay Clancy testified that she suspected the 'manic' Massachusetts mother had bipolar disorder but did not formally diagnose her a month before she killed her children. Clancy, 36, is on trial for killing her three children, Cora, five, Dawson, three, and eight-month-old Callan, at her home in Duxbury, Massachusetts, in January 2023. Her suicide attempt after the killings failed but left her paralyzed and in a wheelchair for life. She has pleaded not guilty by reason of insanity, citing postpartum psychosis, and is also suing her former healthcare providers for medical malpractice and negligence.
