Six months after the Colombian authorities imprisoned them on false charges of rebellion, Oscar Duque, Mario Martínez and Evaristo Mena were released for lack of evidence. They are leaders of the Asociación Campesina del Valle del Río Cimitarra ACVC (Campesino Association of the Cimitarra Valley), with whom CPT-Colombia has a working relationship. Right wing paramilitary groups and government forces have threatened and assassinated members of ACVC because they cry out for just land reform and sustainable development in rural areas.
