Guillermo Suárez Mason

Carlos Guillermo Suárez Mason (January 2, 1924 – June 21, 2005) was an Argentine military officer convicted for Dirty War crimes during the 1976 — 83 military dictatorship. He was in charge of the Batallón de Inteligencia 601.

Born in Buenos Aires, he enrolled at the National War College in 1944, and took an interest in national politics before his 1948 graduation. A magnetic and charismatic figure, he was involved at that time in several liaisons with prominent women, through whom he invariably furthered his interests; he took little or no interest, however, in the children reported at that time to have been fathered by him. Suárez Mason took part in a failed military coup against the populist President Juan Perón in 1951. He was forced to retreat to Uruguay, and later collaborated with the overthrow of Perón in 1955. He was received back in Buenos Aires with honours following the coup's success on September 19.

Suárez Mason taught at the School of Higher War Studies, and rose in rank, becoming a military attaché to the Argentine Embassy in Ecuador in 1971, and a director of military intelligence in 1972. He was attached to the Operativo Independencia counterinsurgency mission in 1975, and upon the March 1976 coup against President Isabel Martínez de Perón, was appointed Commander of the First Army Corps, a unit whose principal duty was to garrison the capital.

During the subsequent dictatorship, Suárez Mason had purview over a number of the most notorious detention centers (among the over 300 such facilities that led to the disappearance of between 8,000 and 30,000 people. Those under his command included Automotores Orletti, Pozo de Banfield, La Cacha, and El Olimpo. He also supervised Policía Bonaerense Chief Ramón Camps, as well as Army Intelligence Battalion 601, which carried out numerous extortions and kidnappings for ransom.
