ガルフ・カルテル
The death of Arturo Guzmán Decena (2002), and the capture of Rogelio González Pizaña (2004), the second-in-line, marked the opportunity for Heriberto Lazcano to take charge of Los Zetas. Upon the arrest of the Gulf Cartel boss Cárdenas in 2003, and his extradition in 2007, the actions of Los Zetas changed—they began to become synonymous with the Gulf Cartel, and their influence grew within the organization. Los Zetas began to grow independently from the Gulf Cartel, and eventually a rupture occurred between them in early 2010.
