The Langmore family was an American criminal family based in Camden County, Missouri. Consisting of the brothers Cade, Russ, and Boyd Langmore, Cade's daughter Ruth Langmore, and Russ' sons Wyatt and Three Langmore, the gang engaged in petty theft from their hovel on the Lake of the Ozarks. In 2017, the family became rivals with the newly-arrived money launderer Marty Byrde, who hired Ruth as an employee at the Blue Cat lodge as recompense for causing her family to punish her for failing to steal his money. Ruth later killed Russ and Boyd after they planned to murder Byrde and flee the state due to the FBI becoming aware of their plot to kill Byrde, as Ruth would have been implicated in the murder.
