Osiel Cárdenas Guillén is a Mexican drug lord and the former leader of the Gulf Cartel and Los Zetas. Originally a mechanic in Matamoros, Tamaulipas, he entered the cartel by killing Juan García Abrego's friend and competitor Salvador Gómez, after the former's arrest in 1996. As confrontations with rival groups heated up, Osiel Cárdenas sought and recruited over 30 deserters from the Grupo Aeromóvil de Fuerzas Especiales to form the cartel's armed wing. Los Zetas served as the hired private mercenary army of the Gulf Cartel.
Los Zetas is a Mexican criminal syndicate, formerly as one of the most dangerous of Mexico's drug cartels. They are known for engaging in brutally violent "shock and awe" tactics such as beheadings, torture, and indiscriminate murder. While primarily concerned with drug trafficking, the organization also runs profitable sex and gun rackets. Los Zetas also operate through protection rackets, assassinations, extortion, kidnappings and other illegal activities. The organization is based in Nuevo Laredo, Tamaulipas, directly across the border from Laredo, Texas. The origins of Los Zetas date back to the late 1990s, when commandos of the Mexican Army deserted their ranks and began working as the enforcement arm of the Gulf Cartel. In February 2010, Los Zetas broke away and formed their own criminal organization, rivalling the Gulf Cartel.
The Gulf Cartel is a criminal syndicate and drug trafficking organization in Mexico, and perhaps one of the oldest organized crime groups in the country. It is currently based in Matamoros, Tamaulipas, directly across the U.S. border from Brownsville, Texas.

The Apodaca prison riot occurred on 19 February 2012 at a prison in Apodaca, Nuevo León, Mexico. Mexico City officials stated that at least 44 people were killed, with another twelve injured. The Blog del Narco, a blog that documents events and people of the Mexican Drug War anonymously, reported that the actual (unofficial) death toll may be more than 70 people. The fight was between Los Zetas and the Gulf Cartel, two drug cartels that operate in northeastern Mexico. The governor of Nuevo León, Rodrigo Medina, mentioned on 20 February 2012 that 30 inmates escaped from the prison during the riot. Four days later, however, the new figures of the fugitives went down to 29. On 16 March 2012, the Attorney General's Office of Nuevo León confirmed that 37 prisoners had actually escaped on the day of the massacre. One of the fugitives, Óscar Manuel Bernal alias La Araña, is considered by the Mexican authorities to be "extremely dangerous," and is believed to be the leader of Los Zetas in the municipality of Monterrey. Some other fugitives were also leaders in the organization.
The Cadereyta Jiménez massacre occurred on the Fed 40 on 12–13 May 2012.

The Blog del Narco, a blog that documents events and people of the Mexican Drug War anonymously, reported that the actual (unofficial) death toll may be more than 68 people. The bodies were found in the town of San Juan in the municipality of Cadereyta Jiménez, Nuevo León at about 4 a.m. on a non-toll highway leading to Reynosa, Tamaulipas. The forty-three men and six women killed had their heads, feet, and hands cut off, making their identification difficult. Those killed also bore signs of torture and were stuffed in plastic bags. The arrested suspects have indicated that the victims were Gulf Cartel members, but the Mexican authorities have not ruled out the possibility that they were U.S.-bound migrants. Four days before this incident, 18 people were found decapitated and dismembered near Mexico's second largest city, Guadalajara.
