Testimony concluded Wednesday in the murder trial of Lindsay Clancy, a mother accused of strangling her three young children in a case that has drawn attention to postpartum mental health.Closing arguments are expected to begin Thursday, before the jury begins deliberating. Clancy, 36, has pleaded not guilty by reason of lack of criminal responsibility, with her lawyers arguing she was experiencing postpartum psychosis when she killed 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan Clancy at the family’s home in coastal Duxbury, Massachusetts, in January 2023. The rare mental illness is linked to the stress, sleep deprivation and hormonal changes that follow childbirth.___EDITOR’S NOTE: This story includes discussion of suicide.
