Forty-nine headless and limbless bodies were found on May 13, 2012 on a northern Mexico highway near the Texan border. The bodies were killings in conjunction with the escalating war between Mexico's two dominant drug cartels, the Zetas and the Sinaloas. The drug wars have been going on for over a decade, although only officially acknowledged on December 11, 2006 by the Mexican government under Felipe Calderon. The Mexican cartels control nearly 90% of all drugs that flow into the United States from Mexico and South America.
