Ricardo García Pellejero and Aniano Jiménez Santo, two supporters of Carlist pretender Carlos-Hugo de Borbón-Parma, were murdered by far-right gunmen.

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.

[5]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 in 1983 was revealed to be chief of personal security for Manuel Fraga, Spain's Interior Minister).

It is commonly accepted[citation needed] that high-ranking Guardia Civil officials, as well as the SECED (CESID's predecessor), supported the conspiracy (code-named Operación Reconquista).

[11] On behalf of the victims, in January 2007 Spanish lawyer José Angel Pérez Nievas pressed charges against Rodolfo Almirón, the leader of Triple A, saying he should be tried for his alleged actions during the Montejurra events.
