Roberto Pellicari, aged 31, and his wife, Sonia Parrondo, 28, never got to celebrate their first wedding anniversary. They had been living in the district of Santa Eugenia for several months, from where Sonia took the suburban train to go to work as a nanny. Roberto worked for the courier company MRW and used to get up early to accompany his wife to work. They both died following the explosions at the El Pozo station.
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.
