From Cleveland to Youngstown to Pittsburgh, a serial killer wreaked havoc along the railyards from the 1920s to the 1940s. Sometimes known as "The Mad Butcher," this murderer chopped up his victims and left them for police or passers-by to find. Despite best efforts from detectives in Ohio and Pennsylvania, the killer was never caught. Not even famed lawman Eliot Ness could solve the case and bring the "Mad Butcher" to justice.
