Angela Craig had been hospitalized three times before her death, and her husband had ordered Potassium Cyanide before her second hospitalization. James Craig's business partner suspected poisoning and called the police. Investigators found that James Craig had been in contact with another woman and had searched for information on arsenic. Angela Craig's sister claimed that James Craig had drugged his wife six years ago and that their marriage was tumultuous.
