Vincent "The Schemer" Drucci (1898–April 4, 1927) was a Chicago mobster during Chicago's Prohibition era who served a lieutenant under Dean O'Banion's North Side Gang and later as gang boss. Drucci was one of the few gangsters to ever be killed by law enforcement.
Born Vincenzo D'Ambrosio, Drucci was a leading member of the North Side Gang and an associate of George "Bugs" Moran, Earl 'Hymie' Weiss, and O'Banion. Drucci was one of the few Sicilian members of the predominantly Irish gang. Known for his inventive and detailed plans from bank robberies to kidnappings of prominent Chicagoans, Drucci earned the nickname "The Schemer". Drucci was involved with the attempted murders of both Al Capone and Johnny Torrio in the turf wars of the 1920s. After the murder of Weiss, Drucci became the leader of the North Side Gang. Unlike his two predecessors, Drucci was not killed by the rival Capone faction, but rather was shot four times and killed during an altercation with Chicago detective Dan Healy on April 4, 1927. Given a lavish funeral at Mount Carmel Cemetery, typical of gangland fashion at the time, Drucci's silver casket cost $10,000 and more than $30,000 in flowers adorned the funeral rooms.
