The other 15 children have been discharged, but they haven’t left the hospital campus. They’re being cared for in the hospital’s auditorium.

“They seem -- some of them are in shock, some are coming into the realization of what just happened, said Dr. Trish Stevens/Sacred Heart Hospital Pensacola, Emergency Medicine. She added, “They have each other and our support.”

The staff at Sacred Heart Hospital has turned the auditorium into a “home.” They’ve brought in therapy dogs, Wii video games, rows and rows of laptops, iPads, snacks and even beds for the students to rest.
