Prosecutor corners Lindsay Clancy's Catholic mother-in-law with 'mortal sin' question

Prosecutors played the faith card Tuesday, asking Lindsay Clancy's Catholic mother-in-law if she knew murder is a mortal sin, part of their push to show Clancy knew what she was doing when she killed her three children, not that she was in a postpartum psychosis as the defense claims.

Lindsay Clancy, 36, is charged with three counts of first-degree murder in the deaths of her three children — Cora, Dawson and Callan, all under 6 years old, who were found strangled in the family's Duxbury home in 2023.
