Eugenio Berríos
Eugenio Berríos Sagredo (14 November 1947 –c. November 1992) was a Chilean biochemist and member of the Dirección de Inteligencia Nacional (DINA), who produced sarin as part of Proyecto Andrea. Berríos also produced the biochemical weapons anthrax and botulism for the DINA. Aided by La Cofradía (the successor of Operation Condor), Berríos fled to Uruguay in October 1991 to avoid testifying about the assassination of Orlando Letelier. On 15 November 1992, Berríos was disappeared and subsequently murdered by Chilean and Uruguayan intelligence agencies. Berríos' remains were found at a beach in El Pinar in April 1995.
