 Famed lawman and Pinkerton agent Charlie Siringo worked heavily on that case, and would years later come into contact with Lefors in the process of working other cases, and would later indicate that Lefors was incompetent, at best, as a lawman.However, US Marshal Frank Hadsell appointed Lefors a Deputy US Marshal in October 1899.Lefors always claimed that Hadsell approached him to take that job based on his hard work on the Wilcox Robbery case.
