Rodolfo Almirón Sena (February 17, 1936 – June 5, 2009) was a former Argentine police officer and a leader of an extreme right-wing death squad known as the Triple A, operating in Argentina from 1973 to 1976 against the left-wing of Peronistas and other political dissidents. The group is held responsible for 1,500 murders of government opponents during the terms of Juan and Isabel Perón.
Almirón was alleged to be the chief operating officer of the squad and was charged with personally executing several murders. In 1975, shortly before the military takeover the following year, Almirón fled to Spain with José López Rega, founder of Triple A, who had been appointed ambassador plenitpotentiary by Isabel Perón. Almirón was briefly located in 1983 in Spain, revealed to be working as chief of security for the former Interior Minister Manuel Fraga. Public outrage caused his dismissal, but he stayed in Spain.
In 2006 an Argentine judge ruled that the crimes committed by Almirón were crimes against humanity and thus excluded from statutes of limitations. A reporter for El Mundo located Almirón in Valencia in December 2006 and interviewed him. He was arrested for murder by the National Police that month, under an extradition request from Argentina. By the time of his trial, Almirón had suffered a stroke and was unable to participate. The trial was suspended. He was held in detention and died in 2009.
Almirón was born in 1936 in Puerto Bermejo, a small riverside town in Chaco Province, Argentina. He attended local schools. Afterward, he moved to Buenos Aires.
Around 1960 he joined the Argentine Federal Police (with jurisdiction over the city of Buenos Aires). Although a member of the robbery task force, Almirón became an associate of the "Prieto gang," which during the early 1960s was one of the most notorious in the Greater Buenos Aires area.
