Arthur John Shawcross was an American serial killer, also known as The Genesee River Killer in Rochester, New York. He claimed most of his victims after being paroled early following a conviction in the manslaughter of two children. In March 1988, Shawcross began murdering again, primarily prostitutes in the area (apart from June Stott, who was a local and was the first one of his victims to be mutilated after her death), before his capture less than two years later. He was convicted of 11 murders, with a 12th not officially charged to him.
