31% of the 11,881 murders committed in the country between January and September this year happened in Guerrero, Morelos, Michoacán and the state of Mexico, an area disputed by cartels such as Beltrán Leyva and its two splinter cells Guerreros Unidos and Los Rojos. 

According to the latest data provided by the National Security System (SNS), the war waged by these organizations against rival cartels such as The Knights Templar and Los Zetas has triggered violence in these states.
