From what I have read about Johnson he didn't have real connections to the Mafia, but he unsuccessfully tried to procure women and become a pimp, and was also involved in gay pornography with Michael Umber who operated at a gay bar that Johnson frequented called Christopher’s End that was controlled by Paul Di Bella, a soldier in the Gambino family. In a July 20, 1971 New York Times article Police Chief Albert Seedman said, “Johnson frequented the Christopher’s End in the weeks immediately preceding the shooting.”
