The case of a deputy U.S. marshal accused of leaking information about a federal witness to members of the Chicago mob has been in the hands of a jury since late Thursday afternoon (April 23), according to a story by Chuck Goudie of WLS-TV Chicago.
Deputy U.S. Marshal John Ambrose (left), 42, is charged with providing information about protected federal witness Nick Calabrese to a friend with connections to the Outfit. Prosecutors say he also leaked classified information regarding reputed Outfit boss John "No Nose" DiFronzo and leaked police information regarding the mob murders of the Spilotro brothers.
Through the testimony of convicted racketeer Mickey Marcello - brother of reputed Outfit leader James Marcello - prosecutors were able to link mob awareness of Nick Calabrese's cooperation in the Family Secrets investigation with Ambrose's friend. Robert Grant, special agent in charge of Chicago's FBI field office, testified April 20 to a confession made by Ambrose. Grant said Ambrose admitted to "a huge mistake" and to having improper friendships.
Ambrose's defense attorney Frank Lipuma argued that his client may have violated policies but committed no crimes. Among the character witnesses brought forward for Ambrose was longtime federal Judge Charles Kocoras. Kocoras did not choose to testify but was brought to the witness stand through a subpoena.
