Alejandra Iglesias López lived in Torrejón de Ardoz with her parents, although she was due to sign the papers to buy a house with her fiancé on the day following the attack. She loved going out, dancing, shopping and spending her Sundays watching films — especially Spanish ones. She was also very fond of her nephews and nieces. One of her nephews, Andrés, had a birthday in April and she had promised him that if he was good, she would give him a little dog.
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 blast killed one of the officers, bringing the total number of people killed by the 11 March killers to 192.
