It was Joe Biondo old crew that were tasked with Albert Anastasia hit. It was the Gambinos through and through on the Anastasia hit.
From the time of the Gallos kidnapping Joe Magliocco, Frank Profaci, Salvatore Musacchia, and John Scimone to the attempt on Larry Gallos life, Carmine Persico was seen at Frank Costellos appartment a few times and Frank told him to remain loyal to his boss, before Costello went back temporarily to prison.
Joey Gallo was not that bright, he messed up and the law didn't need any help from informants, if they did, Gallo would have had to serve a longer sentence.
Carmine Persico was not in Joe Colombo crew, so Joe would not have relayed an order to someone that was not in his crew. A capo gets an order from his boss, he in return tells a soldier or how many needs to be in his crew for the assignment. Persico did not like Carlo Gambino. Also Persico was locked up during the time Joe Magliocco and Joe Colombo had that meeting.
Sonny Franzese went to prison for a crime he did not do, but it was not Persico that set him up. It was another informant that more than likely owed Sonny a large amount of money he could not repay. Not saying Sonny Franzese was a saint, but he was innocent of that charge. Joe Colombo had the most to gain with Franzese going to prison, cause that removed a threat to his leadership.
Persico was not involved with the Joe Colombo shooting, everything points to Anthony Abbatemarco setting it up.
Carmine Persico did have a hand in Joey Gallo death as the order for all Colombo members was to hit Joey Gallo.
Persico benefited greatly from these events, but was no informant. What solidified his standing with Joe Colombo was the hit on Charles "The Sidge" LoCicero, with Greg Scarpa. John Franzese went to prison in 1967, and LoCicero was killed in 1968, so all threats to Joe Colombos reign were neutralized, except for Joey Gallo who was locked up. Franzese and LoCicero were powerful members who could have challenged Colombo at the time, but they were still loyal to the boss regardless of the geippings and rulings in sitdowns which Joe would have made a different call. Colombo was indeed paranoid like most bosses get when they reach the top spot during turmoil years.
