Argentina: José Ignacio Rucci

Thirty-five years after the murder of prominent Argentine trade unionist José Ignacio Rucci, a book by an investigative journalist concludes that he was killed by the Montoneros guerrillas, as many already believed, rather than a right-wing death squad, as others argued.

This is another interesting article by IPS. I haven't read the book ("Operación Traviata. ¿Quién mató a Rucci?" by Ceferino Reato), so I can't comment on it, but the article makes it sound thoroughly-researched. I will add that there is a further twist; according to Martin Anderson's Dossier Secreto: Argentina's Desaparecidos and the Myth of the 'Dirty War', the leader of the Montoneros himself, Mario Firmenich, was a double agent, in league with the military and paramilitaries.
