Mexico City: A wounded migrant stumbled into a military checkpoint and led marines to a gruesome scene, what may be the biggest massacre so far in Mexico`s bloody drug war: a room strewn with the bodies of 72 fellow travellers, some piled on top of each other, just 100 miles from their goal, the US border.
The 58 men and 14 women were killed by the Zetas gang, the migrant told investigators on Wednesday. The gang, started by former Mexican Army special forces soldiers, is known to extort money from migrants who pass through its territory.
If authorities corroborate the story, it would be the most horrifying example yet of the plight of migrants trying to cross a country where drug cartels are increasingly scouting shelters and highways, hoping to extort cash or even recruit vulnerable immigrants.
"It`s absolutely terrible and it demands the condemnation of all of our society," said government security spokesman Alejandro Poire.
The Ecuadorean migrant staggered to the checkpoint on Tuesday, with a bullet wound in his neck. He told the marines he had just escaped from gunmen at a ranch in San Fernando, a town in the northern state of Tamaulipas about 100 miles from Brownsville, Texas.
The Zetas so brutally control some parts of Tamaulipas that even many Mexicans do not dare to travel on the highways in the state. Many residents in the state tell of loved ones or friends who have disappeared travelling from one town to the next. Many of these kidnappings are never reported for fear that police are in league with the criminals.
The marines scrambled helicopters to raid the ranch, drawing gunfire from cartel gunmen. One marine and three gunmen died in a gunbattle. Then the marines discovered the bodies, some slumped in the chairs where they had been shot, one federal official said.
The migrant told authorities that his captors identified themselves as Zetas, and that the migrants were from Brazil, Ecuador, El Salvador and Honduras.
Poire said the government was in contact with those countries to corroborate the identities of the migrants.
The Ecuadorean embassy in Mexico said it was in contact with the surviving migrant, Luis Freddy Lala Pomavilla, and was trying to find out if any of its citizens were among the dead.
Marcio Araujo, Brazil`s consul general in Mexico, said documents found at the scene indicated at least four of the dead were Brazilian. Consular officials for El Salvador said they had no immediate information on whether any Salvadorans were among the victims.
The marines seized 21 assault rifles, shotguns and rifles, and detained a minor, apparently part of the gang.
Authorities said they were trying to determine whether the victims were killed at the same time — and why. Poire noted migrants are frequently kidnapped by cartel gunmen demanding money, sometimes contacting relatives in the US to demand ransoms.
Poire also said the government believes cartels are increasingly trying to recruit migrants as foot soldiers — a concern that has also been expressed by US politicians demanding more security at the border.
The government has confirmed at least seven cases of cartels kidnapping groups of migrants so far this year, said Antonio Diaz, an official with the National Migration Institute, a think tank that studies immigration.
But other groups say migrant kidnappings are much more rampant. In its most recent study, the National Human Rights Commission said some 1,600 migrants are kidnapped in Mexico each month. It based its figures on the number of reports it received between September 2008 and February 2009.
Violence along the northeastern border with the US has soared this year since the Zetas broke with their former employer, the Gulf cartel. Authorities say the Gulf cartel has joined forces with its once-bitter enemies, the Sinaloa and La Familia gangs, to destroy the Zetas, who have grown so powerful they now have reach into Central America.
Teresa Delagadillo, who works at the Casa San Juan Diego shelter in Matamoros just across from Brownsville, said she often hears stories about criminal gangs kidnapping and beating migrants to demand money — but never a horror story on the scale of this week`s massacre.
