>> but then in october of 1981, with the suspect in jail, the monster struck. once again, the victims were young lovers in their 20s, shot to death on a lovers lane in the countryside, murders five and six. the same beretta .22 was the murder weapon. the young woman suffered the same postmortem mutilation, performed with a notched knife. this murder set up a pattern that would repeat itself. police arrested a suspect and the killer, almost as if taunting them, killed again. >> and the police were humiliated and had to release him. >> the monster struck again eight months later in june of 1982 about ten miles south of florence. a young couple had parked just off a busy road. this time, the young man apparently spotted the killer. he saw the murderer coming? >> yes, because he tried to start with the car.
