 SPOILER: Contrary to the films portrayal of Blanche Barrow  inadvertently divulging the identity of C.W. Moss to Texas Ranger  Frank Hamer, thereby setting Bonnie and Clydes deaths in motion, in  real life Hamer found Bonnie and Clyde through simple tracking  methods. Hamer knew that Bonnie and Clyde traveled in a loop. They  would routinely start in Dallas, move north through Oklahoma and  Kansas, cut east to Missouri, south to Arkansas and Louisiana, and  west back to Dallas. Knowing that gang member Henry Methvin (The  C.W. Moss character) had family in Louisiana, Hamer struck a deal  with Methvins father (as seen in the movie) to set up Bonnie and  Clyde.
