Ambulances converged in front of the school, and TV news broadcasts showed at least one person being wheeled to an ambulance on a gurney. Live footage also showed emergency workers appearing to treat possibly wounded people on the sidewalks. It wasn't immediately clear how many were wounded. The Broward County Sheriff's Office tweeted that the shooter was still at large even as the evacuation was underway.
Television footage showed police in olive fatigues, with weapons drawn, entering the school, then dozens of children frantically running and walking quickly out. A police officer waved the students on, urging them to quickly evacuate. Some students exited the building in single-file rows with hands raised overhead to show they carried no weapons. Others held onto other students as they made their way out past helmeted police in camouflage with weapons drawn.
