Crowder Nicks
Before he was ever given a commission to work under Judge Parker, Crowder Nicks made himself known, when he sign-handedly brought in the murderer of Sam Sixkiller in 1887.
The story of the capture of Sixkilller's assailant was written about fully in Art Burton's books, "Black Red and Deadly. African and Indian Gunfighters of Indian Territory. He received a commission shortly after the incident working in and out of Parker's court in Ft. Smith.
In the 1890's he was occasionally mentioned in the local press regarding the retrieval of stolen property. His tenure lasted primarily in the 1890's and is believed to have ended shortly after Parker's death in 1896.
