 Boone had earlier killed James Holstein (or Holdson or Holston) in 1882, a man allegedly hired to "intimidate settlers", after an inebriated Holdson began shooting at him on the Gilmore farm near Vernon, Texas, just across the Red River from the Indian Territory (his sister Elizabeth had married into the Gilmore family and the couple had set up a place there).This killing seemed to be justified in self-defense, but would be brought up later by John and William Murphy, deputy marshal Edward W. "Ed" Johnson, and Sam Criswell, who were having a personal feud with Boone, and would be witnesses against the brothers.Boone, Alfred (aka Alf), Lewellyn (aka Epp, Ep, Ellie), and Charles were arrested near the Anadarko Agency headquarters (what became Anadarko, Oklahoma), for stealing 19 horses in the area around Fort Sill.
