A Massachusetts man who told police he was exorcising a demon and performing a baptism when he shoved his father's head under water multiple times has been convicted of involuntary manslaughter in his death. A jury found Jack Callahan, 22, guilty on Thursday, following an eight-day trial. In June 2021, police in Duxbury got a call that Callahan, then 19, was behaving erratically and that his father, Scott Callahan, 57, was missing near a pond in a park.
