Inés Novellón was 30 years old and worked as a nurse in a public health centre. For the last three years, she had been living with her boyfriend in an apartment in the town of Alcalá de Henares (Madrid province). She normally worked the afternoon/evening shift, but on 11 March 2004 her roster had been changed and she caught the train that exploded alongside Calle Téllez. Her boyfriend was due to take the same route, but a little later than her.
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.
