Chucky Porter in Pittsburgh began cooperating a year into his 28 year sentence. To this day, he is good friends with the two former FBI agents who dogged him for 30 years. According to the Feds, he provided the most substantial assistance that dismantled the LaRocca Crime Family in Pennsylvania, Ohio and West Virginia. His information took down the major players and put an end to the LaRocca Crime Family.

Angelo Lonardo was said to be one of the most important informants to date and was the last guy on earth that anybody thought would cooperate. Until the day he died, he was still pissed off that he was dragged into a narcotics case by his former Capo and crew members.

Jimmy Fratianno was also said to be golden as an informant.
