Sinaloa Cartel
In 2008, the Beltrán Leyva Cartel broke away from the Sinaloa Cartel. After Alfredo was arrested, the Beltrán Leyva brothers blamed "El Chapo" for his capture and retaliated by ordering the murder of Edgar Guzmán López, son of Joaquín "El Chapo" Guzmán Loera. This sparked a war between the Sinaloa Cartel and the Beltrán Leyva Cartel, which allied itself with Los Zetas.
