(Marco Ugarte) (Newser) – A mass grave has been discovered east of Mexico City, and Mexican authorities today said they are conducting tests to determine if it holds some of the 12 people who vanished from a bar in an upscale area of the capital at midday on May 26. At least seven corpses have been recovered so far from the grave in Tlalmanalco, per a Mexico City prosecutor; he said officials would run DNA tests to determine their identities. "We have to wait for the autopsies to know how long they have been dead," he said. Ricardo Martinez, an attorney for relatives of the missing, told the AP earlier that state and federal officials had informed him that 13 bodies had been found on a ranch east of Mexico City, and that the officials suspected they belonged to those who disappeared from the bar. Martinez said a suspect in the case led officials to two graves containing the bodies, and added that he was told there are 13 bodies because the family of one of the missing never reported the person missing.
