The body of Krentz, a longtime rancher, was found on his property near the border with Mexico on Saturday, March 27, 2010. Krentz and his dog were gunned down shortly after he reported spotting someone who appeared to be in trouble. Foot tracks were followed from the shooting scene about 20 miles south, to the Mexico border, and authorities suspect an illegal immigrant. The killing of the third-generation rancher has become a flashpoint in the immigration debate as politicians cite the episode as further proof that the U.S. must do more to secure the violent U.S.-Mexico border.
