Martín Martínez Velasco was shot from behind in the Ozaeta bar in Izurza, where he had gone to make a phone call. A few seconds later, his partner Pedro Antonio Fonte Salido, who was waiting for him in an unmarked police vehicle, was also shot and killed. The terrorists got away in a stolen vehicle.
Three months before the attack, the victim had taken part in an identification parade in a court in Bilbao. It is possible that as a result, ETA identified him as a prominent member of the war on terrorism. The incident led to a review of procedures in cases that might reveal the identity of members of the state security forces.
