Miller became involved in a feud with Pecos Sheriff George A. "Bud" Frazer. While Frazer was on a trip to El Paso, he was informed that Miller had allowed criminals to gain greater control over Pecos. Frazer enlisted the help of Texas Ranger John R. Hughes to secure Pecos. After returning to Pecos, Frazer immediately jailed Miller on a charge of murder. A jury acquitted him of this charge. Frazer also believed that Miller had stolen mules and had him arrested for theft.
