Sinaloa Cartel
With the capture of Óscar Orlando Nava Valencia and the death of Ignacio Coronel Villarreal, of the Sinaloa Cartel, a power vacuum emerged and the Milenio Cartel (then loyal to the Sinaloa Cartel) broke into smaller factions. Being the most notable the Jalisco New Generation Cartel (CJNG) headed by Nemesio Oseguera ""El Mencho" (who suspected the Sinaloa cartel had betrayed their leaders ) and La Resistencia headed by Ramiro Pozos "El Molca"" who switched alliances to form a brief alliance with Los Zetas (La Resistencia was founded by Sinaloa to counter Los Zetas), and started a turf war for the control of the region.
