Carlos de Dios Murias, OFM Conv. (10 October 1945 - 18 July 1976) and his two companions Gabriel Longueville (18 March 1931 - 18 July 1976) and Wenceslao Pedernera (28 September 1936 - 25 July 1976) were two priests and a married man who were killed in the La Rioja province in Argentina. Murias was a professed member from the Order of Friars Minor Conventual and Longueville was a priest incardinated in the Viviers diocese in France before moving to Argentina where he was incardinated into the La Rioja diocese. The two worked together in a La Rioja parish before their deaths while Pedernera, who served as a lay catechist, was married with three daughters and was slain in front of them.
