Ruth Langmore (21 March 1998 – 2022) was an American criminal who was affiliated with the criminal Langmore family in Rocky Mount, Missouri. The daughter of Cade Langmore, the niece of Russ Langmore and Boyd Langmore, and the cousin of Wyatt and Three Langmore, she became known to the Camden County Sheriff's Department for repeated incidences of breaking and entering. In 2017, she was hired at the Blue Cat lodge and bar after blackmailing its new owner Marty Byrde, with whom she had a previous run-in after stealing some of his money, and who knew about his involvement in money laundering. However, Byrde entrusted her with the full-time management of the Lickety Splitz strip club as long as he ran the day-to-day affairs of the business. Ruth, influenced by her father and in league with her uncle Russ, later planned to kill Marty so that she could usurp his money laundering business, but the plan was foiled after Russ' lover, undercover FBI agent Roy Petty, blackmailed Russ into becoming an informer against Ruth, whom he hoped to turn into an informant against Byrde. Russ and Boyd then planned to murder Byrde, steal his money, and go on the run, but, fearing implication in Byrde's murder, Ruth killed her uncles. Ruth continued to serve as a double agent of her father and Byrde, the latter of whom entrusted her with more responsibilities, eventually including the management of his casino. Ruth used her position to keep Wyatt on the straight and narrow path by funding his college education, only for the drug trafficker Javier Elizondro to murder Wyatt. She and Rachel Garrison later stole the casino from Byrde, and she later avenged Wyatt's death by killing Elizondro. In turn, she was ambushed and killed by Elizondro's mother Camila Elizondro at her home.
