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.

It was part of their push to show Clancy knew what she was doing when she killed her three children, not that she was in 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.

Prosecutors concluded their case Monday morning.

On Tuesday, Assistant District Attorney Shanan Buckingham asked Susan Clancy, Lindsay's mother-in-law and a Catholic, if she knew murder was a "mortal sin."
