On August 3, 1966, Bruce was found dead in the bathroom of his Hollywood Hills home at 8825 N. Hollywood Blvd. The official photo, taken at the scene, showed Bruce lying naked on the floor, a syringe and burned bottle cap nearby, along with various other narcotics paraphernalia. According to legend a policeman at the scene said “There is nothing sadder than an aging hipster” which itself possibly was one of Lenny Bruce’s lines.

The official cause of death was "acute morphine poisoning caused by an accidental overdose."
