Acero, director of the weekly economics bulletin Informador Socioeconómico and a veteran reporter, was killed in Armenia, Quindío, by an unknown assailant who shot him three times on the street and then fled. No one has been apprehended. Acero’s colleagues believe his murder may be related to his outspoken stance against corruption and his decade-long career as a journalist. Acero was the former Armenia regional director for the national radio network Radio Caracol and a former reporter for Radio Cadena Nacional.
