Right about the time that Pinochet was dispatching the Caravan of Death, Montealegre was arrested by the military police and taken to the National Stadium in Santiago, which had been converted into a gigantic holding pen and torture center. Montealegre was still in high school, a fatherless teenager active in politics, who had seen little outside the capital. After a few months in the National Stadium, he was sent along with a group of about six hundred others to an ex-saltpeter town that had been converted into a concentration camp.
