A few minutes after the bell rang for lunch today, Crescenta Valley High freshman Myles Dalmau said he heard a thud.
At first he thought it was a gunshot, he said. Then about two dozen people crowded around a student who fell from a building.
Dalmau said the student was face down and motionless.
"My friend was there when it happened. He fell a few feet away from her," Dalmau said. "It was pretty disturbing."
