ガルフ・カルテル
Upon the arrest of the Gulf Cartel boss Cárdenas in 2003 and his extradition in 2007, the panorama for Los Zetas changed—they started to become synonymous with the Gulf Cartel, and their influences grew within the organization. Los Zetas began to grow independently from the Gulf Cartel, and eventually a rupture occurred between them in early 2010.
