Authorities have arrested a suspect in the murder of Councilman Anyel Castillo, which occurred in a border region shared with Colombia’s Norte de Santander department. The area has long been identified by residents and specialized organizations as having a significant presence of irregular armed groups. Details surrounding the arrest and the suspect’s identity have not been immediately released. Castillo’s assassination adds to concerns about political violence in the region. The location of the crime, a known hotspot for illegal armed activity, suggests a possible connection. Investigations are ongoing to determine the motive and any further involvement of armed groups. This arrest represents a step toward justice for Castillo and potentially uncovering a wider network of criminal activity.
