In August 1991, Santiago Martin Rivas and Carlos Pichilingüe Guevara elaborated the Operations Plan called Cipango. The official objective was to regulate the participation of Army Intelligence in the identification, capture and handing over to the authorities of subversive criminals. However, this plan was conceived and approved at the time when testimonies point to the beginning of the Colina group's activities, constituting the façade for their extrajudicial executions.
