Albert O’Dell and James Lamb were itinerant farmworkers near Lebanon, Indian Territory in 1886. Strangely, they took the wives of their two employers as mistresses. Then the two couples decided to take things a step further. O’Dell and Lamb, with planning help from the women, murdered the two men. But locals found the whole thing suspicious. Deputy U.S. marshals arrested the pair and took them to Fort Smith. They were tried in front of Hanging Judge Isaac Parker (photo). Sure enough, O’Dell and Lamb were executed in 1887. The women were never arrested or charged.
