Mexican army arrests lieutenant to 'Chapo Guzman' who allegedly ordered activist's killing
MEXICO CITY (AP)—Mexico's army arrested a lieutenant to Sinaloa cartel leader Joaquin "El Chapo" Guzman who they believe ordered the killing of anti-violence activist Nepomuceno Moreno, authorities said Sunday.
Mexico's defense department said Jesus Alfredo Salazar Ramirez was arrested in Huixquilucan in Mexico state on Thursday, and that there is an arrest order for him issued by a court in Texas for intent to distribute cocaine.
A department statement called Salazar one of Guzman's most important lieutenants, and alleged that he ran drug planting, production and trafficking operations for the cartel.
He is also accused of ordering the November 2011 killing of Moreno, a 56-year-old sidewalk seafood vendor who became one of the most visible faces of Mexico's anti-crime movement after his 18-year-old son Jorge Mario disappeared.
Saying masked police had snatched his son, Moreno pleaded his case directly to President Felipe Calderon last year in a meeting with members of poet Javier Sicilia's Movement for Peace with Justice and Dignity.
