Allende is a city in the Mexican state of Coahuila. The city serves as the administrative center for the surrounding municipality of Allende. History The name "Allende" is in honor of Ignacio Allende, a hero of Mexico's War of Independence. The town's folk hero is Arnulfo González who was gunned down in the mid-1920s, and has a "corrido" sung by artists such as Vicente Fernández and many others. Prior to 1832 the settlement was known as San Juan de Mata. Los Zetas Massacre In February, 2014, members of the Army, Navy, State, and Federal Police forces began searching for the remains of at least 300 residents of the region, who had been murdered in 2011 and buried in a series of clandestine graves in local ranches.

But Martinez and Gonzalez saw an opportunity in his escape. If they could persuade Vasquez to cooperate, it would give them rare access to the senior ranks of the notoriously impenetrable cartel and a chance to capture its leaders, particularly the Treviño brothers, who had killed their way onto the list of the DEA’s top targets. Miguel Ángel Treviño was known as Z-40, Omar as Z-42. What Martinez wanted were the trackable PINs, or personal identification numbers, of the Treviños’ BlackBerry phones. Vasquez had left the agent plenty of leverage. His wife and mother were still living in Texas. The DEA threatened to imprison Vasquez’s mother and wife if he did not get the trackable PINs for the Treviños.
