11 October 1957 – Rhonda Bell Martin
Rat poison was Rhonda Bell Martin’s weapon of choice as she bumped off her family one by one in the ‘50s.
The serial killer admitted killing her mum, two husbands and three of her children. And while she didn’t say why, it’s thought that she was after the life insurance payouts.
Martin was a waitress in Montgomery, Alabama, and it was only after she tried to kill her fifth husband that her crimes came out into the open.
She tried to top her spouse who was actually her former son-in-law by poisoning him. But she failed and he turned into a paraplegic. But the suspicious nature of his illness alerted the authorities.
Her confession ensured that she earned the death penalty and Martin was sent to the electric chair in 1957, aged 49.
