Yesterday, Gioeli and his fellow wiseguys learned that yet another Colombo mobster has been secretly working with the FBI for more than six months, and has tape recorded more evidence linking Tommy Shots to the 1999 rubout of former underboss William (Wild Bill) Cutolo.

Sources tell Gang Land that when Maragni, who had been charged with home invasion, drug dealing, bribery, and several violent extortion counts and detained as a danger in January, was released on home confinement in April, wiseguys suspected he was a “rat” and shunned him.

“The guy’s detained, facing more than a hundred years and all of a sudden he’s out, on house arrest with an ankle bracelet, and he’s coming around,” said a neighborhood source. “I said hello, and good-bye,” he said, adding, “What am I, a fucking jerk?”

“He’s supposed to be sick, and he’s coming to card games,” added an underworld source who told Gang Land that he “told everyone the guy was a rat. I can’t believe people talked to the guy.”

“The FBI actually tried to use him as a spy in the defense camp,” said another attorney, who recalled that Maragni “yelled and screamed and tried to intimidate an attorney into letting him attend a co-defendants’ meeting at the MDC. (Metropolitan Detention Center.)”

Asked by Gang Land if Maragni’s guilty plea was a scam, attorney Richard Shanley said he did not have “any comment that I want to make about this matter. He pled guilty and that’s all I want to say about that.”

FBI agent Curtis and supervisor Seamus McElearney referred calls to spokesman Jim Margolin. Said Margolin: “The FBI’s conduct with regard to cooperating witnesses is strictly regulated and the FBI complied with all internal guidelines and legal requirements in this matter.”

Gioeli’s lawyer, Adam Perlmutter, declined to comment, as did Saracino’s attorney, Samuel Braverman.
