John "No Nose" DiFronzo (1928) is a Chicago mobster and allegedly the reputed Boss of the Chicago Outfit. A former enforcer and Caporegime, DiFronzo was convicted along with then-current Chicago boss Samuel "Black Sam" Carlisi on federal racketeering charges in 1993, however, the conviction was reversed on appeal and DiFronzo was released from prison in 1994. Accordingly, DiFronzo has more than two dozen arrests. After the death of Carlisi in the late 1990s, DiFronzo was believed to have maintained acting boss of the Chicago Outfit. In 2005, DiFronzo avoided indictment in the "Family Secrets" trial of top Chicago Mafia leaders in 18 unsolved murders. Other defendants were prominent Chicago mobsters James Marcello and Joseph "Joey the Clown" Lombardo. As of 2008, DiFronzo is out of prison and allegedly running the Chicago Outfit. In late March of 2009 John DiFronzo and his brother were included in a civil RICO complaint filed in Chicago by Joseph Fosco. This complaint alleges that members of the Chicago Outfit are guilty of committing extortion upon and conspiracy to murder Mr. Fosco.
