[PAR] [TLE] Jaime Zapata [SEP] Jaime Jorge Zapata (May 7, 1978 – February 15, 2011) was an Immigration and Customs Enforcement, Homeland Security Investigations Special Agent who was ambushed and murdered by the Mexican criminal group Los Zetas in San Luis Potosí, Mexico.  He was one of the two agents that were ambushed in a part of the country that is increasingly under the influence of drug violence.  Zapata's death is the second highest-profile killing of a U.S. agent in Mexico—the first one was Enrique Camarena, an undercover DEA agent who was tortured and murdered by the former Guadalajara Cartel. [PAR] [TLE] Los Zetas [SEP] Los Zetas (] , Spanish for "The Zs") is a Mexican criminal syndicate.  Considered by the US government to be "the most technologically advanced, sophisticated, efficient, violent, ruthless, and dangerous cartel operating in Mexico", the organization has expanded beyond the traditional purview of drug trafficking and also runs profitable sex trafficking and gun running rackets.  The origins of Los Zetas date back to the late 1990s when commandos of the Mexican Army deserted their ranks and began working as the enforcement arm of the Gulf Cartel.  In February 2010, Los Zetas broke away from their former employer and formed their own criminal organization.
