From the producer of the award-winning PBS documentary Return to Giant comes a new look at a very old incident. In 1915 a group of Mexican banditos raided the McAllen Ranch, one of the largest in the area. The next day a group of Texas Rangers supposedly arrived and eliminated the perpetrators. However, the real story is not as tidy as it has been portrayed. Roland Warnock, a 19-year-old cowboy working on the Guadalupe Ranch near present-day Edinburg, witnessed two of these killings when he saw Texas Rangers from Company D shoot two unarmed men in the back and leave their bodies by the side of the road. The effects of these killings by the Rangers are being felt in south Texas some 80 years later. This single incident brings into play much of the roots of the distrust between Mexicans and the Rangers, as well as the continued friction between Hispanics and Anglos in Texas.
