Alexander Díaz, commonly known as "Calarcá Córdoba," is the leader of the Jorge Suárez Briceño Bloc and the larger bloc known as the EMBF (Estado Mayor de Bloques y Frente). The EMBF was formed following the split from the broader FARC dissident network and operates in southern Colombia, particularly in Meta, Guaviare, and other nearby regions.
Carcalá's criminal activities span various illegal operations, including drug trafficking, illegal mining, and human rights abuses. The Jorge Suárez Briceño Bloc is heavily involved in drug trafficking in the Amazonian departments, which account for about 5% of Colombia's coca cultivation for cocaine production. The group also controls gold and coltan mining areas in the Amazon region and northeastern Antioquia.
In addition to drug trafficking and mining, Carcalá and the EMBF are accused of serious human rights violations. These include the recruitment of children, particularly Indigenous youth, forced displacement of local communities, threats and killings of social leaders, and the contamination of territory with anti-personnel mines and improvised explosive devices.
