Student: We assembled outside for a fire drill, then we heard gunshots

A Santa Fe High School student described the moment they all heard gunshots.

"So, it was just a normal-like class day. We all were doing our work in first period. And then all of a sudden like it's a fire drill," 14-year-old junior Angelica Martinez said.

"So we followed the fire drill procedures. And then we went outside. Like we were all standing there, but not even five minutes later, we all start hearing gunshots."

That's when everybody starts running, she said, despite teachers telling them to "stay put."

"But we're all just running away."
