"Serial killer Arthur Shawcross died Monday. He was 63. The man known as the Genesee River Killer claimed 11 victims between 1988 and 1990. Shawcross targeted women in high-risk professions such as prostitution. A textbook sexually sadistic serial killer and psychopath, Shawcross usually dumped his victims in the river, sometimes returning to the scene of the crime to masturbate."
