Yet Parker's other seamier life was catching up with him. Heroin and alcohol dependency, a narcotics arrest leading to a revoking of his New York City cabaret license, unprofessional behavior, and mental health issues saw Parker slipping into a morass. He tried to commit suicide twice in 1954 and dissipation continued until his death on March 5, 1955. The attending physician had guessed Parker's age to be 60 years old, yet he was only 34.
