— SANTIAGO DE COMPOSTELA, Spain (AP) — Spanish royals and political leaders joined hundreds in Santiago de Compostela's storied cathedral Monday evening to mourn the 79 people killed in last week's train crash, as investigators prepared to examine the train's "black box" data recorders for more clues into the country's worst rail disaster in decades.
Driver Francisco Jose Garzon Amo faces multiple counts of negligent homicide for the tragedy. The investigation has increasingly focused on him and his failure to brake as the train hurtled into a high-risk curve.
The black box could clear up whether there was a mechanical or technical failure. Experts will start examining it Tuesday under the instruction of Judge Luis Alaez, a court spokeswoman said on condition of anonymity in keeping with court policy.
Alaez late Sunday charged Garzon, but allowed him to leave custody without bail. He was driven from the court in a police car after dark, but it was not clear where he was taken.
Several Spanish newspapers, including leading daily El Pais, reported Monday that the driver acknowledged to the judge that the train was travelling too fast, but that he briefly stopped paying attention. The court spokeswoman said she could not comment on details of the testimony.
Officials said 70 people injured in the train accident remained hospitalized, 22 of them in critical condition.
Meanwhile, Crown Prince Felipe and his wife, Princess Letizia, and his sister, Princess Elena, attended the Mass at Santiago de Compostela's cathedral, along with Prime Minister Mariano Rajoy and other politicians.
Hundreds of other people stood and sat in the broad plaza outside, overlooked by the cathedral's majestic twin bell towers, where a giant video screen broadcast the service. Black mourning ribbons dotted the city.
The imposing cathedral, consecrated in 1128, is one of Christianity's most venerated shrines and is the last stop for the faithful who make it to the end of the El Camino de Santiago pilgrimage route that has drawn Christians since the Middle Ages. Catholic pilgrims converge on the city to celebrate a festival honoring St. James, the disciple of Jesus whose remains are said to rest in a shrine there.
