The story goes that Frank Hamer was working for Dan McSween around 1900. The rancher asked the 16-year-old to kill someone for him; Frank refused. McSween then shot and seriously wounded Hamer—who later returned and fatally wounded McSween in a gunfight.
But author John Boessenecker, in his new book Texas Ranger: The Epic Life of Frank Hamer, the Man Who Killed Bonnie and Clyde, says it didn’t happen that way. McSween did shoot Hamer—but Frank didn’t get revenge. The rancher sold his place in 1904 and died of natural causes in Kaufman, TX in 1909.
