Simpson refused to admit himself into a traditional rehab facility. In 1995, he employed Dr. Stephen Ammerman to help him with his addiction. Ammerman, who had a history of drug abuse himself, believed that in order for Simpson to quit drugs, he had to use other drugs to combat the painful withdrawal symptoms. Ammerman designed what has been called a "dangerously unorthodox" detox program, which included several medications (including morphine) for Simpson to take at home. On August 15, 1995, Ammerman was found dead in the shower of the pool house on Simpson's estate. It was later determined that Ammerman died of an accidental overdose of cocaine, Valium, venlafaxine, and morphine.
