Famous Chicago Mob Rat, Nick Calabrese, Cashes In Chips From WitSec, Fmr. Outfit Button Took Down Three Of Windy City’s Biggest Wiseguyshttps://gangsterreport.com/famous-c...n-three-of-windy-citys-biggest-wiseguys/March 13, 2023 — The man who brought the Chicago mafia to its knees, former Outfit soldier and hit man Nick (Nicky Slim) Calabrese, died this week at the age of 80 in the Witness Protection Program. Calabrese was the only “made” man in Windy City mob history to take the stand against the Outfit.
Calabrese’s cooperation with the FBI led to the groundbreaking Operation Family Secrets case, a 2005 indictment, nailing 14 Chicago mobsters for 18 different gangland homicides. His subsequent testimony at the 2007 trial brought down his own brother, South Side crew boss Frank (Frankie Breeze) Calabrese, Outfit acting boss Jimmy Marcello and Outfit consigliere Joey (The Clown) Lombardo. Marcello, 79, is the only one still alive, serving out a life sentence as a guest of the federal government.
