The Triple A was secretly led by José López Rega, Minister of Social Welfare and personal secretary of Juan Perón. Rodolfo Almirón, arrested in Spain in 2006, was alleged to be his chief operating officer of the group, and was officially head of López Rega's and Isabel Perón's personal security. He was extradited from Spain in 2006 and prosecuted; he died in jail in June 2009. SIDE agent Anibal Gordon was another important member of the Triple A, although he always denied it. He was tried in Argentina in 1985 after the restoration of democracy and convicted in October 1986. Gordon died in prison of lung cancer the next year.
