On the morning of her 16th birthday, in her AP music class, Megan Storm thought she was going to die.
The sophomore at Lake Brantley High School in suburban Orlando, Fla., said she heard an announcement over the intercom that the school was in a code red lockdown — it was a drill, but Storm said students were not told that. She and her classmates hid in the dark, behind an instrument locker.
"It was just really quiet. And we all sort of huddled together," Storm said.
