Firefighters say they have located four students trapped in a dormitory that crumbled in Italy's devastating earthquake but did not say if they were alive or dead. Chief firefighter Sergio Basti said Tuesday that rescue crews were evacuating the area around the dorm because they plan to begin "surgically" removing big chunks of the building to reach the four students. Asked if the students were alive, Basti said only that in his experience he had found people alive after 14 days. He said that rescue crews needed to "lighten" the building to reach the four since they are in a hard-to-reach spot. Several dozen rescue crews are at the scene of the collapsed building.
