Juan Francisco Pastor Pérez was married and had two children. His first grandchild had been born less than a year earlier. At 51, he had been working as a telephone technician at the Convention Centre for more than two decades. He took the metro to work each day from the outlying district of Las Palomeras. In the days leading up to March 11, he had more work due to the impending elections, which had altered his routine and he decided to take the suburban train to save time. He was killed in the explosions in 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.
