Because of a federal judge’s change of heart more than two decades ago, former Bonanno mob acting captain Robert (Little Robert) Lino, Jr. walked free from prison last week and checked into a halfway house after doing a near quarter of century of time for racketeering, stock scams and participating in a pair of gangland rub-outs related to Bonanno business.

“Little Robert,” 57, ran Wall Street rackets for the Bonannos in the late 1990s. He admitted to taking part in the murders of Bonanno mob associates Louie Tuzzio and Bobby Perrino in January 1990 and May 1992, respectively, as part of a 2001 plea deal. U.S. District Court Judge Nicholas Garaufis was at first ready to reject, but then changed his mind and allowed Lino. Jr. to cop to the two homicides and a 50-million dollar a year stock-manipulation conspiracy in return for a 30-year sentence.

Tuzzio, 25, was shot to death behind the wheel of a stolen Chevy in Brooklyn for botching a mob execution and accidentally wounding a Gambino mobster in the process of finishing off his target. Then-Gambino John Gotti allegedly called for Tuzzio’s slaying. Bonanno capos summoned Tuzzio with the promise of being made into the borgata, however a hit team riddled his car with bullets, killing him instantly ; he also angered Bonanno administrators by demanding a button and complaining his induction ceremony wasn’t occurring quick enough for his liking.

The 54-year old Perrino, the Bonanno’s boots-on-the-ground in their newspaper distribution racket at the NY Post for years and the son-in-law of one-time underboss Nicholas (Nicky Glasses) Marangello disappeared when Bonanno leaders worried he was getting too religious and they feared he was about to cooperate against the crime family. Per court testimony, Little Robert was a member of the clean-up crew on the hit and upon arriving for disposal duties, they realized Perrino was still alive and stabbed him to death with an ice pick. Twenty-one years later, authorities found Perrino’s remains on the property of a Staten Island construction company.
