15 mutilated bodies are found inside two abandoned SUVs in the state of Jalisco, a region that is under dispute between Los Zetas and the Sinaloa Cartel. The Mexican authorities believe the massacre is a response by Los Zetas for the 2012 Nuevo Laredo massacres reportedly carried out by Joaquín Guzmán Loera (a.k.a. "El Chapo"), Mexico's most-wanted drug lord.
