@thecrimedesk: Lindsay Clancy’s former mother-in-law, Sue Clancy, took the stand Tuesday during the Massachusetts mother’s murder trial. During cross-examination, prosecutors asked Sue — who is Catholic — whether she knew that murder is considered a “mortal sin” in the Catholic Church, prompting the judge to immediately call a sidebar. Sue, the mother of Lindsay’s estranged husband, Patrick Clancy, also testified about the family attending Mass and Lindsay’s mental health treatment in the weeks before the January 2023 killings. #LindsayClancy #SueClancy #PatrickClancy #TheCrimeDesk
