The Complete Organized Crime Database on the Americas
US government documents obtained by a Washington DC-based non-governmental organization shed some light on one of the darkest periods in recent Mexican history: the multiple massacres of migrants between August 2010 and May 2012. However, the full story will not be known until the government of Mexico opens its own vaults.
Newly declassified US security reports highlight how the Zetas recruited men from Guatemalan Special Forces unit the Kaibiles for use in operations in both Mexico and Guatemala, underlining concerns about the deployment of the unit on anti-narcotics operations.
At least 13 people have been killed in three separate gun battles in the Mexican border city of Matamoros, in what could be the first sign of a predicted upsurge in violence following the July capture of the Zetas leader Miguel Angel Treviño, alias "Z40."
The Zetas and Gulf Cartel are imposing a toll on travel between two states in eastern Mexico, in a case highlighting the extent of the incursion of organized crime into daily life where the state lacks presence.
Authorities in northern Mexico will request greater military assistance from the central government in the face of a recent surge in violence, as concern mounts over the possibility of renewed upheaval in a region once controlled by the Zetas.
A Salvadoran man who sold illegal migrants to Mexico's criminal group, the Zetas, for $800 apiece has been sentenced to four years in jail, in a case that sheds lights on the workings of the human trafficking chain.
Guatemala's authorities say Mexico has detained a leader of the Zetas who led the Mexican criminal group's operations in Guatemala, another significant blow to the Zetas' operations in this Central American nation.
El Salvador's President Mauricio Funes said hundreds of grenades stolen from the country's military were intended for the Mexican criminal group the Zetas, illustrating possible arms trafficking links between the Mexican organization and the vaunted Salvadoran group known as the Texis Cartel.
Mexico has announced the arrest of an alleged Zetas member linked to the massacre of 17 musicians, in a case that highlights the struggle for social, as well as physical, territory between cartels in Mexico.
It is tempting to separate Mexico's drug cartels into six hierarchical groups, each competing for trafficking turf. The reality, however, is that the Sinaloa Federation, the Gulf Cartel, the Tijuana Cartel, the Juarez Cartel, the Zetas and La Familia, not to mention several new offshoot organizations, are fluid, dynamic, for-profit syndicates that sometimes operate under the umbrella of what are effectively conglomerates but more often than not operate as independent, smaller-scale franchises.
