Reputed mobsters Frank Caruso, James Inendino and Peter DiFronzo were among the people the FBI considered threats to the safety of mob hitman turned federal witness Nick Calabrese.
The revelation came today during the testimony of FBI Agent Michael Maseth in the trial of deputy U.S. Marshal John Ambrose, who is on trial for allegedly leaking key details about Calabrese to the mob.
Ambrose, who guarded Calabrese as part of a security detail, has said he made a mistake by discussing information about Calabrese with a family friend but had no intention of the information making it to mobsters.
Calabrese began cooperating with the government on Jan. 15, 2002, after agents confronted him with DNA evidence linking him to a mob murder. Calabrese eventually admitted to committing 14 mob murders and provided the feds information about another 22 Outfit hits.
