Three years later, Audrey took out a $25,000 life insurance policy on her daughter, Carol; a $25,000 accidental death rider took effect in August 1978. Within a few months, Carol began experiencing trouble with nausea and was admitted to the emergency room several times. A year after filing the insurance policy on her daughter, Audrey gave Carol an injection that she claimed would alleviate the nausea. However, the symptoms only worsened, with Carol enduring numbness in her extremities. After medical tests found no disease, Carol's physician, fearing the symptoms were psychosomatic, had her undergo psychiatric testing at Birmingham's Carraway Methodist Hospital. There, Carol secretly received two more injections from her mother, who warned her not to tell others about the shots.
