Vincent Drucci, also known as "The Schemer" (born Vincenzo D'Ambrosio; January 1, 1898 – April 4, 1927), was a Sicilian-American mobster during Chicago's Prohibition era who was a member of the North Side Gang, Al Capone's best known rivals.
A friend of Dean O'Banion, Drucci succeeded him by becoming co-leader.
He is the only US organized crime boss to have been killed by a policeman.
