Perisco spent most of his adult life under indictment or in prison, but remained the head of the Colombo family in New York City, the newspaper reported.

Perisco was convicted of racketeering and murder in the 1986 Commission trial, considered one of Rudy Giuliani's biggest victories against organized crime, WABC reported.

Persico and the reputed bosses of the Genovese and Lucchese crime families were convicted of being members of the Commission, the panel that resolved major disputes, the Times reported. The Commission set policies for the five New York crime families: the Bonanno, Colombo, Gambino, Genovese and Lucchese factions.

Law enforcement officials believed Persico was heavily involved in the assassinations of mob bosses Albert Anastasia in 1957 and Joey Gallo in 1972, the newspaper reported.

Weintraub said Persico's funeral will be in New York City, WABC reported.
