of Zabalza and other residents of Orbaizeta remained quiet. On 1 May 1991, police confirmed that they had found several people who had been killed in an explosion in the remains of a SEAT 131 car, and identified via their identity documents María Rosa Diez Sáez (30) from Barakaldo and Jesús Fernández Miguel (40), the owner of the car, and found bank savings account documents from another person, reported as Soledad Múgica Areitioaurtena (40) from Ermua, in the wreckage. El Pais reported that Sáez and Areitioaurtena had been involved in radical assemblies, but that Miguel was unknown to authorities. The following day, Iraultza contacted the newspaper Egin to confirm that the three fatalities were its members. Police sources stated that the three deceased had just placed devices which had detonated in Bilbao and Barakaldo before they were killed manipulating an explosive device. José Miguel Moros Peña According to the newspaper El Pais, on Friday 27 June 1986 José Miguel Moros Peña (18), a resident of Portagalete and construction worker for Urgandía, a subcontractor for firms Dragados and OCP Construcciones (as of January 2019 a part of ACS Group) was starting a piece of drill machinery (later reported as a crane) at around 7:50 am when a bomb attached to it exploded, fatally injuring him. The bomb's timer had apparently failed to detonate the bomb, but the movement of the drill machinery was thought to have initiated the detonation. An anonymous call was made prior to the detonation to the Santurzi Municipal Police at 11:45 pm on Monday 23 June 1986, and a bomb squad was sent out to check but reportedly found nothing. The police chief of Bilbao later stated that the police considered the call to be one of many false alarms, and did not consider checking the area again in daylight.
