Texas authorities have charged a man with killing a uniformed sheriff’s deputy at a Houston gas station Friday night. Law enforcement officials on Saturday arrested Shannon J. Miles, of Cypress, and charged him with capital murder in the fatal, “execution-style” shooting of Harris County deputy Darren H. Goforth, NBC News reports. Deputy Goforth was filling up his patrol car at a Houston Chevron gas station when the gunman approached from behind, opened fire, and fired again as Goforth lay on the ground, according to Reuters.
