DeSimone's fifth murder was of John Gotti's protege, a young gangster named Fredrick "Foxy" Civano. DeSimone had dated Foxy's sister and then beaten her up when he dumped her, prompting Foxy to threaten to kill DeSimone. When DeSimone heard about the threat, he went to Foxy's apartment and knocked on the door; Foxy opened the door, punched DeSimone in the face, and then DeSimone shot Foxy between the eyes, killing him.
