[The economics instructor] said he hid behind a desk with about 20 … students, and that one was shot in the leg.
About 20 other students ran out of the room’s side doors, he said. The students who were sitting in the middle row had a harder time escaping the gunfire. “The students in the middle were impacted the most,” he said. “Many of them were lying there and they were not moving. I have no idea how many.”
