Ex-Cop Denies He Passed Info to the Mob

Friends of ours: James Marcello, Michael Marcello, Nick Calabrese, John "No-Nose" DiFronzo
Friends of mine: William Guide, John Ambrose

Speaking publicly for the first time, a former cop accused of receiving sensitive information about the mob from a deputy U.S. marshal denied he did anything wrong.

William Guide became agitated Tuesday when asked if he passed on to a reputed mobster sensitive information he got from deputy U.S. Marshal John Ambrose. "I didn't do anything," an emphatic Guide told the Chicago Sun-Times on Tuesday. "I didn't do anything wrong. You don't know the whole story. You're making me out to be the bad guy in this whole thing."

Guide was responding to a story in Tuesday's Sun-Times in which Ambrose's lawyer, Frank Lipuma, said if the government's allegations were true, Guide "may or may not have taken advantage of Mr. Ambrose."

Ambrose, 38, was charged last week with theft of information after the government said he leaked confidential material about protected mob witness Nick Calabrese to "Individual A." Sources say that is Guide. Guide has not been charged in the case.

His lawyer, Rick Beuke, said Guide looks at Ambrose as a son. Beuke said he doesn't believe there was anything sinister going on between Ambrose and Guide, two longtime friends. If Ambrose talked about anything sensitive, he may have just been bragging, Beuke said. "He wanted to impress Guide like he'd want to impress a father," Beuke said. "It's like a kid coming home and saying: 'Dad, I hit a home run.' "

Ambrose twice briefly guarded Calabrese, who is set to testify in a mob trial this spring, when he was in Chicago. Shortly after, the feds say Ambrose revealed to Guide confidential facts he obtained from a file on Calabrese.

That information made its way to mobsters, the government alleges. The feds released transcripts of prison surveillance tapes in which reputed mobsters -- Jimmy and Michael Marcello -- can be heard discussing specifics about Calabrese's movements in Chicago and his cooperation. In coded language, they refer to both Guide and Ambrose, the FBI said. Information about Calabrese came from a file Ambrose had accessed, the feds allege.

The Marcellos refer to getting information from the "baby-sitter," whose father was a cop convicted in the Marquette 10. Federal authorities say that's specific information identifying Ambrose.

They allege that a third party passed the information to mobsters and do not allege that Ambrose disclosed sensitive information intending it to go to the mob. Ambrose denies wrongdoing.

Guide briefly served prison time with reputed mobster John "No Nose" DiFronzo.

Guide was a Chicago Police officer when he was convicted in the Marquette 10 scandal in the 1980s along with Ambrose's father, Thomas. Thomas Ambrose died in prison at age 37. Since then, Guide and John Ambrose have been close friends, talk often and share a love for wrestling, both of their attorneys said. "John was seeking out Bill's approval. He wanted Bill to be proud of him as a marshal," Beuke said.

Beuke said Guide and DiFronzo know each other. But he doesn't believe there's an ongoing friendship. Beuke said Guide, a South Sider, runs a pizza business and is too busy working to be a mob associate. "I don't think there's any evidence of Bill passing along any information to the mob," Beuke said.
