Alfonso Martínez Bellas was having lunch with three colleagues (Antonio García Argente, Mariano González Huergo and Miguel Hernández Espigares) at the Arrieta bar-restaurant. The front door was locked, but someone knocked on the back door. When the owner’s fifteen-year-old daughter opened the door, thinking it might be a late diner, three terrorists entered without saying a word and riddled the victim and his colleagues with machine-gun fire. All four died instantly.
Three ETA members were convicted of the crime. José Ramón Foruria, who was handed over by the Venezuelan authorities in 2003, was in charge of drawing a sketch of the establishment and planning the attack. Jaime Rementería was responsible for surveillance and for providing information to the perpetrators of the attack. Fidel González lent his car to the terrorists and put them up in a flat for several days, including the night before they carried out the attack.
