William Jesus Marrufo hacks his mother to death with 2 meat cleavers and a boning knife because he believed she was possessed by Satan
According to Marrufo’s father, the family had noticed he was mentally ill for some time and tried to get him help, which he refused. When he attacked his mother he was hallucinating, believing she was possessed by Satan and that killing her was the only way to save her soul. During trial he was found not guilty by reason of insanity and has been placed in a state mental facility.
