250 Killers

Arthur John Shawcross became one of America's most infamous serial killers after murdering 14 people in New York between 1972 and 1989. After serving a prison sentence for killing two children, Shawcross was released on parole and later went on to murder at least 12 women in the Rochester area. His crimes remained unsolved for several years before investigators linked him to the murders through surveillance, witness testimony, and forensic evidence. Shawcross was sentenced to 250 years in prison, where he remained until his death in 2008.
