Born Rhonda Belle Thomley in 1907, Martin confessed to murdering six people, including three of her daughters, her mother and two husbands.
Before her arrest she had worked as a waitress in Birmingham, Alabama. Her crimes only surfaced when police began to investigate the illness of her husband, Ronald, in the March of 1953.

Eight months after Claude’s death she married his son Ronald, who was subsequently left paralyzed from the effects of poison.
