 In June 1898, while tracking rustlers, Standifer arrived in Clairemont, Texas, a rough town at the time, and the location in which Jeff Hardin, brother to gunman John Wesley Hardin, had been shot and killed.Standifer located a rustler named Bob Kiggins there, but Kiggins refused to surrender, and in the gunfight that followed Standifer shot and killed Kiggins.During this period, an animosity between Standifer and Higgins developed, one that has never truly been explained.
