An 86-year-old mob hitman is on the streets after serving nearly 50 years behind bars for a 1961 rubout ordered by Mafia legend Anthony "Tony Pro" Provenzano, according to the New York Daily News.

Harold "Kayo" Konigsberg, who used a cord from venetian blinds to strangle Anthony "Three Fingers" Castellito in his upstate New York home, was quietly sprung from a New York prison in a surprise parole from a life sentence, allowing him to spend his final days at a gated community in Florida, according to the paper.

The gangster was released in June from Mohawk Prison in Rome, N.Y., where he'd been held for nearly a half-century after being sentenced for 20-to-life for the contract killing of Castellito, a Teamster rival of Provenzano. Castellito's body was allegedly buried in New Jersey but was never found.

The mobster, who is still remorseless about his crimes, according to the newspaper, was suspected by the feds for nearly 20 other mob hits.
