In March 1974, representatives of the police forces of Chile, Uruguay and Bolivia met with Alberto Villar, deputy chief of the Argentine Federal Police and co-founder of the Triple A death squad, to implement cooperation guidelines. Their goal was to destroy the "subversive" threat represented by the presence of thousands of political exiles in Argentina. In August 1974, the corpses of Bolivian refugees were found in garbage dumps in Buenos Aires. In 2007, McSherry also confirmed the abduction and torture during this period of Chilean and Uruguayan refugees who were living in Buenos Aires, based on newly declassified CIA documents dated June 1976.
