Gregorio Sauceda Gamboa is a Mexican illegal drug trafficker of the Los Zetas, when Los Zetas were the armed wing of the Gulf Cartel.
[3][4] Sauceda was a former investigative police officer,[4] who helped smuggle an average of 10 tons of cocaine and 30 tons of marijuana across the border each month.
[5] He was captured on April 30, 2009 in Matamoros, Tamaulipas along with his wife and his bodyguard, Miguel Ángel Reyes Grajales.
[3] On 24 March 2010, the United States Department of the Treasury sanctioned Sauceda-Gamboa under the Foreign Narcotics Kingpin Designation Act (sometimes referred to simply as the "Kingpin Act"), for his involvement in drug trafficking along with fifty-three other international criminals and ten foreign entities.
[7] 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.[8]
