TUCSON, AZ - DECEMBER 09: Human remains in body bags lie in the refrigerated morgue of the Pima County Office of the Medical Examiner on December 9, 2014 in Tucson, Arizona. Forensic anthropologists attempt to identify the deceased by studying personal effects and bodily remains. Most are from undocumented immigrants, many of whom died of dehydration while crossing illegally into the U.S. from Mexico. The center currently has 90 bodies in the morgue and, on average, receives 176 per year, most found by ranchers and Border Patrol agents. Identified remains are repatriated, along with personal items, to their home countries, and the others will be cremated. (Photo by John Moore/Getty Images)
