#15 – Arthur Shawcross
Nicknamed “Genesee River Killer,” this psychopath committed his first murder in 1972 when he lured a 10-year-old boy into a wooded area in the proximity of New York City where he raped and later murdered the boy. After this gruesome crime, Shawcross committed another crime. This time, his victim was a young girl. He first raped the girl and later murdered her. He got captured for that crime and was sentenced to 14 years in prison.
Shawcross was released in 1988 after serving 14 years in prison. However, his thirst for blood was the same even though he spent 14 years in prison because of it. Not soon after his release, Arthur brutally murdered several female prostitutes. He was once again captured and got sentenced to 250 years in prison. He died of cardiac arrest in 2008.
