S5·E11 An Inconvenient Marriage

After learning her first husband had an illegitimate child, Raynella Dossett Leath begins to control every aspect of her new husband life, including his death when she's overcome by greed. Soon afterwards, another shocking secret is revealed. Margaret Rudin was sick of her husband wasting all of his money on alcohol and guns (money that she wants to spend) that she kills him and dismembers him before going on the run. Linda Lou Charbonneau got sick of her first husband and married his nephew; when neither man's financial status met Linda's satisfaction, her solution was to kill both of them.
