Students see emotional triggers all over Florida school

PARKLAND, Fla. (AP) — Aria Siccone returned to school haunted by the image: A terrified boy was knocking on the door of her locked classroom as the shooting began at Marjory Stoneman Douglas High School, but no one would let him in, fearing the shooter would follow.

That boy was fatally shot, one of 14 students and three staff members gunned down two weeks ago. And as classes finally resumed, there were reminders and triggers everywhere on campus: "Even if someone knocks at the door, like that scared me a lot today," Siccone said.
