Mexican environmental activist Noé Salomón Vázquez Ortiz was murdered the early afternoon of Aug. 2 in his hometown, Amatlán de los Reyes, in the eastern coastal state of Veracruz. The killing came one day before the town was to host the Tenth National Meeting of the Mexican Movement Against Dams and in Defense of Rivers (MAPDER). Vázquez Ortíz and a minor were gathering flowers and seeds for a floral tribute to be used at the conference when a group of men appeared, ordered the minor to leave and began stoning Vázquez Ortíz. His body was found later with the hands and legs bound and the throat slit. State police arrested four men the day of the murder; they reportedly said they had personal differences with the murdered man.

Mexican naval forces announced the arrest Sept. 27 of Iván Velázquez Caballero, AKA "El Taliban" or "Z-50"—said to be a top commander of Los Zetas who had recently defected to the rival Gulf Cartel. El Taliban was said to be in a struggle with his former boss, Zeta commander Miguel Treviño Morales AKA "Z-40" for control of the "plaza" (trafficking theater) in San Luis Potosí, where the arrest took place. From 2007 until his recent break with the Zetas, he had also controlled the plazas in Zacatecas, Aguascalientes, Guanajuato, Nuevo León and Coahuila. He had a reward of 30 million pesos ($2.3 million) on his head.
