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

During the Duxbury case trial, Lindsay Clancy's former mother-in-law testified that Clancy was begging for help months before killing her three children and attempting suicide. Simultaneously, prosecutors questioned the Catholic mother-in-law regarding whether murder constitutes a mortal sin. This line of questioning aimed to establish that Clancy possessed the mental capacity to distinguish right from wrong prior to the crimes. The testimony highlights the conflict between Clancy's pleas for assistance and the prosecution's focus on culpability.
