Leak threatened 'most important witness'

A leak of information about turncoat Mafiosi Nicholas Calabrese could have led to the death of "the most important organized crime witness that has ever testified in this district, and perhaps in the entire United States," FBI Special Agent Michael Maseth stated in court earlier this week.

Maseth was testifying at the trial of Deputy U.S. Marshal John Ambrose, who is accused of revealing confidential details about Calabrese while Calabrese was in the witness protection program. The leak is believed to be the first ever for the program, according to a Chicago Tribune story. Calabrese cooperated in the Family Secrets case, helping the federal government jail several senior members of the Chicago Outfit.
