Ambrose (right) was convicted of stealing and leaking information from the file of Nicholas Calabrese, a former Chicago mobster who aided prosecutors on the Family Secrets Case and was placed in the Witness Protection Program.

Federal agents became aware of the leak after they bugged the visitors room at a prison in Milan, Michigan, where Chicago Outfit boss James Marcello was held. During a visit by Marcello's brother Michael, the two men were overheard discussing an underworld ally within federal law enforcement.

The Marcellos referred to their "mole" in law enforcement as "the Babysitter" and indicated that he was the son of a former Chicago policeman who went to prison years ago after extorting money from drug dealers. From that information, federal authorities decided that Ambrose was the source of their information leak.

Ambrose's jury deliberated for three days, according to a story by the Chicago Tribune. One of the jurors had to be excused from the 12-person panel because she was sick with flu-like symptoms. The law permits a jury of 11 to reach a verdict.

Ambrose remains free on bond. He is expected to appeal. Judge John Grady provided grounds for appeal when he was slow to stop the playing of an FBI video recording of the two mobsters discussing Ambrose. The judge ordered the jury not to consider the tape as evidence.
