Richard Chase was perhaps one of the most derranged serial killers out there. All his victims were chosen randomly, he had no set modus operandi, and he was fueled by his psychotic episodes. His first victim was Ambrose Griffin, a  51-year-old who was helping his wife carry groceries when he was killed. Chase callously killed him in a drive-by shooting, which is highly unusual for a serial killer.The bottom photograph shows police investigating Chase’s pick-up truck, were they found his gun, mutilated animal remains, and strange stains on the passenger seat.
