Paul John Knowles, nicknamed the Casanova Killer, went on a four-month killing spree in 1974. He still remains one of the lesser known serial killers of his generation. Learn all about this psychopath who wanted fame before his life ended.

November 7, 1974

As she entered her home in Milledgeville, Georgia, all Ellen Carr probably had on her mind was going to bed. She was a registered nurse who worked a night shift, and although her small family welcomed the money, the job was a demanding one.

Inside, the house was unnaturally quiet. She found that odd. Her husband, 45-year-old businessman Carswell Carr, and 15-year-old daughter, Amanda, usually greeted her when she came home from the hospital.

That wasn't the only sign that something was seriously amiss. As an investigator later put it, "The [place] looked as if it had been attacked by an animal." Mirrors were smashed. Slashed furniture lay everywhere, some of it in pieces. Books from the bookshelves littered the floor.

Had they been robbed? Where were Carswell and Mandy? Heart pounding, Mrs. Carr ran from room to room, calling out. Minutes later, she was back outside, screaming hysterically. Neighbors called the police to what was obviously the scene of gruesome double homicide.

Carswell Carr's nude corpse was lying face down on the couple's bed, hands bound behind his back and 27 stab wounds, inflicted by scissors, all over his body. The medical examiner later determined that he had died of a heart attack, likely brought on by the torture. Down the hall, Amanda was also face down in her room, one nylon stocking tied tightly around her neck and another shoved down her throat. To compound the horror, she appeared to have been raped after death.
