The Mafia's Boss of Bosses — Killed Inside His Own Office

Salvatore Maranzano won a Mafia war, reorganized New York's underworld into Five Families, and declared himself “Boss of Bosses.” Months later, killers walked into his Park Avenue office and murdered him. But his death did more than remove a Mafia boss. It helped end an entire model of power. On September 10, 1931, men posing as government agents entered Maranzano's office at 230 Park Avenue. His guards were disarmed. Maranzano was stabbed and shot. This documentary follows what can actually be established about the killing — and separates the surviving evidence from the mythology that grew around it. The story leads from the Castellammarese War and Joe Masseria's murder to Charles “Lucky” Luciano, Meyer Lansky, the Five Families and the rise of the Commission. Maranzano's organization survived him. His title did not. No invented dialogue. No manufactured final words. Where historical accounts conflict, the film says so.
