Former Chicago police officer and Outfit associate Fred Pascente is the man who links Tony Spilotro, one of Chicago's most notorious mob figures, to William Hanhardt, chief of detectives in the Chicago Police Department. Pascente and Spilotro grew up together on Chicago's Near West Side, and as young toughs they were rousted and shaken down by Hanhardt.

While Spilotro became the youngest made man in Chicago Outfit history, Pascente joined the police department. Soon taken under Hanhardt's wing because of his connections, Pascente served as Hanhardt's fixer and bagman in the department for more than a decade. At the same time, Pascente remained close to Spilotro, making frequent trips to Las Vegas to party with his old friend while helping to rob the casinos blind.
