On 3 April 1976, Inspectors Jesús María González Ituero and José Luis Martínez Martínez of the General Police Force, stationed San Sebastian (Guipúzcoa), crossed the border to do some shopping and see a film in Hendaye (France). As they left the Varietés cinema, they were kidnapped by a unit of ETA político-militar and later tortured. The terrorists then shot the officers in the back of the head. Their bodies were buried in a bunker on the beach at Chambres d’Amour, in the town of Anglet, where they were found a little over a year later. The documents of the police officers was found at the home of a member of ETA-pm.
Jesús María González Ituero was 25 years old and had begun working as a police officer in San Sebastian seven months before, after completing his military service in the Accommodation Office.
