Forensic FilesBitter Potion (In HD)

A waitress's life unravels when she and her family fall victim to a silent, invisible poison. The case of Peggy Carr exposed the dangers of thallium, a metal that left her with 50 times the maximum exposure in her system after being added to her soda. Health officials traced the source back to a neighbor with a chemistry background, who had a history of criminal activity and a notebook detailing poisoning methods. A threatening letter and thallium found in his shed led to his arrest and conviction for murder.
