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 during the mid-1970s. The group is held responsible for 1,500 murders of government opponents, and Almirón was charged with being one of the chiefs and organizers of the squad. Almirón was born in 1936 in Puerto Bermejo, a small, riverside town in Chaco Province, Argentina. Almirón was incorporated into the Argentine Federal Police (with jurisdiction over the city of Buenos Aires) around 1960.
