Edgar Valdez Villarreal
Edgar "La Barbie" Valdez Villarreal was a Sinaloa cartel lieutenant and the operator of its armed group known as Los Negros, formed by the Sinaloa Cartel to counter the operations of the rival Gulf Cartel's Los Zetas. Los Negros have been known to employ gangs such as the Mara Salvatrucha to carry out murders and other illegal activities. The group is involved in fighting in the Nuevo Laredo region for control of the drug trafficking corridor. Following the 2003 arrest of Gulf Cartel leader Osiel Cárdenas, it is believed the Sinaloa Cartel moved 200 men into the region to battle the Gulf Cartel for control. The Nuevo Laredo region is an important drug trafficking corridor into Laredo, Texas, where as much as 40% of all Mexican exports pass through into the U.S.
Following the 2004 assassination of journalist Roberto Javier Mora García from El Mañana newspaper, much of the local media has been cautious about their reporting of the fighting. The cartels have pressured reporters to send messages and wage a media war. The drug war has spread to various regions of Mexico such as Guerrero, Mexico City, Michoacán, and Tamaulipas.
On 30 August 2010, Villarreal was captured by Mexican Federal Police.
