In 1976 a 23-year-old German girl named Anneliese Michel died from malnutrition and dehydration after nearly a year of undergoing the rites of exorcism. Years earlier, Anneliese had spent some time in a psychiatric hospital due to the effects of epilepsy and depression but she, along with her deeply religious parents, was convinced that her problems were caused not by psychological illness but by demonic possession.
