Myiriam López Díaz, 31, was a schoolteacher, although she was working at Alcatel. She and her husband, to whom she had been married for five years, were both from Salvadiós (Ávila). They had a 22-month-old daughter whom Myriam left at the nursery before going on to Santa Eugenia station. Her family searched for her for 24 hours in hospitals in Madrid before finally receiving confirmation of her death.
11 March 2004 fell on a Thursday. Early that morning, a number of terrorists with links to Al-Qaeda planted thirteen bombs on four suburban trains covering routes running through Madrid. Ten of the bombs exploded between 7.37 and 7.39 am, when the trains were at Atocha, El Pozo and Santa Eugenia stations and alongside Calle Téllez. 191 people were killed in the attack and around 1,500 were wounded. It was the deadliest terrorist attack in Spanish history. On 3 April 2004, agents from the Special Operations Group (GEO) were about to enter an apartment in Leganés where the perpetrators of the attacks were believed to be hiding when the terrorists detonated twenty kilograms of explosives in an act of collective suicide. The ensuing blast killed one of the officers, bringing the total number of people killed by the 11 March bombers to 192.
