The Lindsay Clancy murder trial resumed Thursday in Plymouth Superior Court for a full day of testimony. The first witness was a Massachusetts medical examiner who examined the body of Clancy's infant son.Clancy has admitted to killing 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan at their Duxbury, Massachusetts home on Jan. 24, 2023. Clancy, 35, pleaded not guilty to charges of first-degree murder. The defense argues she is not criminally responsible because she was overmedicated and experiencing extreme postpartum psychosis. Prosecutors are making the case that Clancy knew what she was doing when she killed her children, and they suggest she faked a suicide attempt after.
