FILE- In this Sept. 12, 2009 file photo, investigators work a crime scene where a man and woman were murdered in the streets of Ciudad Juarez, Mexico. El Paso, Texas and its neighbor across the Rio Grande, Ciudad Juarez, are the Cain and Abel of the Mexican border. They are like reverse photographic images of each other. One is a model of civic order, the other an urban war zone just a few hundred yards away.
