A California man is guilty of murder in a bizarre case wherein the suspect claimed he was a werewolf who killed a vampire. Atascadero man Mark Andrews, 51, went to his neighbor's home and fatally shot her in the doorway with a rifle, a jury determined Friday. Andrews pleaded insanity in the 2013 killing of 52-year-old Colleen Barga-Milbury, KSBY reports. "I'm disappointed," defense attorney Ilan Funke-Bilu told the station.
