In the fall of that year, Brown, Billy the Kid, and a few of the remaining Regulators trailed a herd of rustled horses to the little town of Tascosa in the Texas Panhandle. After the horses were sold the Regulators returned to their old haunts, but Brown, named in two murder warrants in the state of New Mexico, wisely remained in Texas where he eventually became a lawman. It has not been established whether he was a deputy sheriff of Oldham County, Texas; Marshal of Tascosa or a constable. He had a quick temper and was quickly dismissed because he "was always wanting to fight and get his mane up."
