 Yet somehow on a hilltop surrounded by civil guards, more than 50 gunmen could establish themselves for 24 hours, set up an ambush, open fire and make their getaway without attracting official attention.Among the alleged perpetrators of the crime were Stefano Delle Chiaie, a neofascist Italian; and 15 former members of the "Argentine Anticommunist Alliance" (Triple A), including Rodolfo Almirón (who, 1983, was revealed to be chief of personal security for Manuel Fraga, Interior Minister in Spain).The public outcry at this report forced Fraga to dismiss Almirón.
