In this Aug. 10, 2012 photo, Dr. Gregory Hess, Chief Medical Examiner for Pima County, holds a skull from a John Doe body bag, a suspected illegal immigrant, at the Pima County morgue in Tucson, Ariz.  The death of migrants crossing the Southwest border has long been a tragic consequence of illegal immigration and, many say, the massive increase in U.S. border enforcement. For some, the tragedies are a powerful motivator in pushing Congress to act this year on a larger immigration reform package.  (AP Photo/Ross D. Franklin)
