José Gerardo Álvarez-Vázquez (aka: El Indio or El Chayán) is a Mexican drug trafficker who worked for the Beltrán-Leyva Cartel and then for Édgar Valdez Villarreal's criminal organization known as Los Negros.
He was also in charge of some routes for the transport of drugs to the U.S. on behalf of the Beltrán Leyva and Sinaloa Cartels.
[2] On 2 October 2008, the United States Department of the Treasury sanctioned Álvarez Vázquez under the Foreign Narcotics Kingpin Designation Act (sometimes referred to simply as the "Kingpin Act"), for his involvement in drug trafficking along with nine other international criminals and six entities.
[3] The act prohibited U.S. citizens and companies from doing any kind of business activity with him, and virtually froze all his assets in the U.S.[4] On April 21, 2010, the Mexican military raided a household in Huixquilucan; during the raid, troops were met with gunfire from cartel gunmen.
After the gunfight, soldiers cordoned off the zone which led to the capture of Gerardo Alvarez-Vázquez.
