A mob capo whose 2002 decision to become an informant led to the dismantling of the Bonanno family's leadership was sentenced to time served of 2 years in Brooklyn federal court on Thursday for racketeering crimes that included murder.

Frank Coppa, 73, was the first Bonanno-made man to become a government cooperator. He testified against boss Joseph Massino, who subsequently became an informant himself, and other leaders of the family.

He admitted to conspiracy in the 1981 murder of Dominick "Sonny Black" Napolitano, who was killed for his role in introducing an undercover agent to the inner workings of the family, events that were chronicled in the 1997 movie "Donnie Brasco."

Coppa served 2 years in prison more than a decade ago while awaiting trial on the charges that eventually led to his informing. Prosecutors urged U.S. District Judge Nicholas Garaufis to show leniency, calling his cooperation a "historic event."
