A spy working for one of Mexico's most powerful drug cartels had no trouble infiltrating the U.S. Marshals Service office at the U.S. Embassy in Mexico City, according to a new article in El Universal. He found the position, criminal investigator, by browsing through the embassy's online job bank. "Felipe," as the man now under witness protection is known, had been on the Beltran-Leyva cartel's payroll since 2005, when he infiltrated the Mexican office of Interpol. The job at the U.S. Embassy allowed him to share with the cartel the names and telephone numbers of people under investigation by the DEA and the Marshals Service. In exchange, the Beltran-Leyvas paid him a monthly salary of $30,000.
