[When Sammy 'The Bull" Gravano agreed to cooperate with the FBI in prosecuting John Gotti and other members of the Gambino family, an initial meeting was arranged between Gravano and a federal agent named Bruce Moaw. The meeting began as follows:] Bruce Moaw walks over and shakes my hand [Gravano recalled]. He opened the door and I got in. I told him, "Are you Moaw?" He says, "Yes," and I said, "I heard you were from Iowa."
