FILE - In this May 16, 2011 file photo, the hand of a corpse hangs from a bed with a syringe being used by forensic experts at a makeshift morgue inside a refrigerated container as they try to identify hundreds of bodies found in mass clandestine graves in Durango, Mexico. The count of unidentified dead in Mexico is growing. Many say the country's police are simply overwhelmed by the number of drug war casualties as they struggle with poor forensic capabilities and the reluctance of some witnesses and victims' relatives to help. That apparent futility is drawing increasing criticism from Mexicans weary of the government-led offensive against drug cartels, who are also fighting among themselves.
