As first responders rushed to the Parkland high school where Nikolas Cruz killed 17 people and wounded 15 more, one thing quickly became clear: People were dying. "This is going to be a big event," a Coral Springs-Parkland Fire Department commander said in newly released audio recordings from the Feb. 14 mass shooting at Marjory Stoneman Douglas High School. "See if I can have somebody up there contact all the area hospitals. Just let them know that we have an incident and we may be sending patients in all directions so they need to start preparing for it. Trauma centers especially.” The fire department released the audio Thursday at the request of the Miami Herald, South Florida Sun Sentinel and CNN. The recordings could offer new insight into how well authorities responded to a chaotic scene. The audio reveals fire-rescue workers scrambling to get the wounded out of the freshman building all while not knowing where Cruz was — and if he might strike again.
