Rhonda Bell Thomley Martin was an American serial killer. A 49-year-old waitress in Montgomery, Alabama, she confessed in March 1956 to poisoning her mother, two husbands, and three of her children. She denied killing two other children. Her fifth husband, formerly her son-in-law, was poisoned like the others but survived only to be left a paraplegic. It was his illness that led authorities to look into the strange deaths surrounding Martin. Prosecutors said collecting insurance proceeds prompted her serial killing spree, although this is unlikely, since she only collected enough to cover burial costs, and she never admitted this was the case. She was convicted of murdering 51-year-old Claude Carroll Martin in 1951 by surreptitiously feeding him rat poison and was executed in Alabama's electric chair on October 11, 1957.
