Santiago Omar Riveros

Riveros was born on 4 August 1923 in Villa Dolores, a small city in the province of Córdoba, to parents Arturo Riveros and María Ester Castro. Riveros was married and was father to two children. ==Military career==

Early years Riveros entered the Colegio Militar de la Nación as a first-year cadet on 1 February 1943, after having finished secondary school. He left as an artillery gun sub-lieutenant on 14 December 1945, having graduated fifth out of a class of 201. Years later, he trained to be a General Staff Officer at the Escuela Superior de Guerra, which in time afforded him a path into the army's highest levels. The Dirty War During Argentina's last military dictatorship (beginning in March 1976), General Riveros held the positions of Commander of Military Institutes, Head of the Campo de Mayo Garrison and head of Defence Zone IV. Under his responsibility were Campo de Mayo and a group of partidos of Buenos Aires Province. His second commander and chief of staff were, first Brigade General Fernando Humberto Santiago (1976), and then later Brigade General Reynaldo Benito Antonio Bignone (1977-1978). On 2 February 1979, Riveros relieved Vice-Admiral Luís María Mendía of his positions as Chief of the Argentine Military Delegation before the Inter-American Defense Board, Armed Forces' Adviser at the Permanent Mission of the Argentine Republic to the United Nations, and also at the Permanent Mission of the Argentine Republic to the Organization of American States. He then simultaneously exercised all these functions himself until 30 January 1980, after which he withdrew from them and went into effective retirement. Ambassador to Uruguay Once Divisional General Riveros had gone into retirement in January 1980 and no longer bore his military title, Roberto Eduardo Viola's government appointed him Argentina's ambassador to Uruguay on 26 June 1981. There he was supported by the former head of the Naval Intelligence Service, Captain Eduardo Osvaldo Invierno, who served as Naval Military Attaché in the Oriental Republic of Uruguay beginning on 15 January 1980. Riveros retained this ambassadorial post under both Leopoldo Fortunato Galtieri's and Reynaldo Benito Antonio Bignone's de facto presidencies, until 10 December 1983, when he was dismissed from his diplomatic functions by the incoming, newly elected constitutional president, Dr. Raúl Ricardo Alfonsín, who named former vice-president Dr. Carlos Humberto Perette as Riveros's replacement. == Legal situation ==

courthouse in 1985. In 1989, Riveros was the recipient of a pardon granted by President Carlos Saúl Menem through Decree no. 1002 of 6 October of that year. He remained exempt from any penalty for the crimes against humanity of which he had been found guilty in 1985. He was the first military officer to explain his own role during Argentina's state terrorism (the Dirty War), putting together a lengthy document in which he stated, among other things: Convictions and imprisonment In Italy, Riveros was sentenced to life imprisonment and 18 months' solitary confinement in 2000 for the disappearance and death of three Italian citizens. In 2006, Riveros found himself being tried for crimes against humanity in relation to matters such as Operation Condor. That same year, the Argentine courts decided that the pardon that had been bestowed upon Riveros was unconstitutional. Eventually, on 13 July 2007, the Supreme Court of Argentina quashed the pardons that had been protecting Riveros and furthermore ruled that all such pardons were unconstitutional. On 12 August 2009, Riveros was found guilty in the murder of fifteen-year-old Young Communist militant Floreal Avellaneda, who had been kidnapped on 15 April 1976, and tortured at the Villa Martelli police station and then at Campo de Mayo, together with his mother. His body was found months later over on Uruguay's coast, bound hand and foot, with obvious signs of both torture and impalement. The judges, Lucila Larrandart, Martha Milloc and Héctor Sagretti, of the San Martín Tribunal Oral convicted Riveros of the crimes of unlawfully depriving persons of freedom, aggravated by violence, trespassing, theft, acts of torture aggravated by victims being the targets of political persecution, aggravated homicide and hiding a body. The bench handed down a life sentence to be served in the Federal Penitentiary Service (Spanish: Servicio Penitenciario Federal). Five of Riveros's underlings were judged together with him for these crimes perpetrated at Campo de Mayo, and they were given sentences of between 8 and 25 years. The judges determined that Floreal Avellaneda's killing constituted a crime against humanity, but set aside any contention that it had been part of a genocide. On 5 July 2012, within the framework of the "Plan Sistemático", the Federal Tribual Oral no. 6 of the Federal Capital imposed a 20-year prison sentence on Riveros for "kidnapping, retaining and hiding a ten-year-old minor in conjunction with making the status of a minor under ten years of age uncertain" in two acts. Sentenced alongside Riveros were Jorge Rafael Videla and Reynaldo Benito Antonio Bignone. In July 2022, he received a further sentence for crimes against humanity committed at Campo de Mayo. However, he served his sentence at home, under house arrest, rather than in a prison cell. ==Death==

Riveros died in Buenos Aires on 24 May 2024, at the age of 100. == See also ==
