John "No Nose" DiFronzo (born December 13, 1928-died May 27, 2018) was a Chicago mobster and the boss of the powerful Chicago Outfit.
DiFronzo, a former enforcer and caporegime, first appeared in the criminal record in 1949. He got the nickname "No Nose" because he sliced off part of his nose while jumping through a window during a 1949 clothing store burglary. Reportedly, the police gave him back the missing part which was almost perfectly restored. In 1950, DiFronzo served two years in prison for burglary.
DiFronzo was a suspect in the unsolved 1952 murder of Charles Gross, a West Side politician with suspected ties to organized crime. He was a member of the Three Minute Gang, and identified as a member of a loansharking operation along with former Chicago police officers Albert Sarno and Chris Cardi in 1964. Imprisoned syndicate leader Joseph Aiuppa chose DiFronzo to head criminal operations in Chicago's western suburbs over acting syndicate boss Joseph Ferriola. Eventually, he became one of several de facto leaders running The Outfit in Chicago. He has a made-man brother named Peter DiFronzo who was convicted of warehouse burglary.
He was convicted along with Chicago boss Samuel "Black Sam" Carlisi on federal racketeering charges in 1993. DiFronzo, under the orders of Carlisi, had conspired with his gambling capo, Donald "The Wizard of Odds" Angelini, to subterfuge gambling operations at the Rincon Indian Reservation near San Diego, California. The 1993 conviction was reversed on appeal, however, and DiFronzo was released from prison in 1994.
In 2009, John DiFronzo, Rudy Fratto, and several others were named in a civil lawsuit by Joseph Fosco, the son of late Teamsters treasurer Armando Fosco, alleged to have tried to extort $400,000 from Fosco.
