In 2006, General Manuel Contreras, head of the Chilean secret police DINA under Pinochet, alleged in testimony sent to Judge Claudio Pavez (overseeing the Huber case) that Pinochet and his son Marco Antonio Pinochet had been involved in the clandestine production of chemical and biological weapons, and in the production (under Eugenio Berríos's direction), sale and trafficking of cocaine.[37] These allegations were never fully investigated by the Chilean courts, nor by a government commission set up to establish their veracity.
