On Valentine’s Day 1940, Toni Jo Henry murdered traveling salesman Joseph Calloway in a Louisiana rice field. Desperate to free her husband, Claude “Cowboy” Henry, from a 50-year prison sentence, she and an accomplice robbed Calloway, stripped him, and shot him for his car and clothes. Instead of saving Cowboy, she became the only woman ever executed in Louisiana’s electric chair. This is a true story of obsessive love, deadly devotion, and a marriage that ended in murder.

The trial of Kouri Richins lasted three weeks, had forty-two witnesses, and only three hours of deliberation before she was found guilty of murdering her husband, Eric Richins using a drink laced with enough fentanyl to kill him five times over.
