The dictatorships and their intelligence services were responsible for tens of thousands of killed and missing people in the period between 1975 and 1985. Analyzing the political repression in the region during that decade, Brazilian journalist Nilson Mariano estimates the number of killed and missing people as 2,000 in Paraguay; 3,196 in Chile; 297 in Uruguay; 366 in Brazil; and 30,000 in Argentina. Estimates of numbers of killed and disappeared by member countries during the period of operation are 7,000-30,000 in Argentina, 3,000-10,000 in Chile, 116–546 in Bolivia, 434–1,000 in Brazil, 200–400 in Paraguay and 123–215 in Uruguay. While many sources combine these numbers into a single death toll attributable to Operation Condor, killings directly linked to Condor's cross-border military and intelligence cooperation between South American dictatorships are, by definition, only a small subset of the total. McSherry, for example, estimated in 2002 that at least 402 individuals were killed or "disappeared" in Condor operations: "Some 132 Uruguayans (127 in Argentina, 3 in Chile, and 2 in Paraguay), 72 Bolivians (36 in Chile, 36 in Argentina), 119 Chileans, 51 Paraguayans (in Argentina), 16 Brazilians (9 in Argentina and 7 in Chile), and at least 12 Argentines in Brazil". McSherry added that "some 200 persons passed through Automotores Orletti, the key Condor detention center in Argentina," and cautioned that "these figures are likely underestimates". In 2009, McSherry offered a range of "hundreds, or thousands ... murdered in Condor operations," acknowledging that "the number still has not been finally determined".
