Authorities became suspicious of Blanche Moore after her new husband, Rev. Dwight Moore, fell mysteriously ill in 1989. When a toxicology screening revealed arsenic in his system, authorities decided to exhume five other people closely related to Blanche. All five bodies showed elevated levels of arsenic.
She was convicted in 1990 for the death of her second husband and remains on death row in North Carolina.
