"I see pieces of the ceiling fall, and I turned around and go into the little thing into the street, and I see the whole thing just come down," La Bonita supervisor Adolfo Navarret. "It was weird because there was no noise, like, I don't know, out of the blue, it just happened."

Others were trapped inside, but eventually everyone was evacuated.

Clark County's fire chief said the awning fell due to a structural problem.
