TLALMANALCO, Mexico — Mexican authorities said Thursday that they have found a mass grave east of Mexico City and are testing to determine whether the grave holds some of the 12 people who vanished from a bar in an upscale area of the capital nearly three months ago.
At least seven badly decomposed corpses have been recovered so far from the grave in Tlalmanalco, Mexico City prosecutor Rodolfo Rios told reporters. He said the victims cannot be identified so far based on clothing, nor can they tell the cause of death.
‘‘We will look at DNA tests that have been taken . . . to confirm or discard scientifically if the bodies found are the people who disappeared from the bar,’’ Rios said.
Rios said there were more bodies and the work would continue in an area near Rancho La Mesa Ecological Park in the state of Mexico.
The young bar-goers vanished from the after-hours Heaven club at midday on May 26, a block from Mexico’s leafy Paseo de Reforma, the city’s equivalent of the Champs-Elysees.
