Ignacio Olaiz Michelena stayed out with some friends in San Sebastián until 10.30 pm and then left to go back to his home in Andoáin. He never arrived. At around 11:30 pm, the security guard at the Lasa y Lecumberri timber yard contacted the Guardia Civil, because an employee at the yard had heard gunshots.
Ignacio was found dead in his car in a large pool of blood, with several bullet wounds to the head. A number of thousand-peseta banknotes had been placed in his hands.
