A Sun Sentinel investigation revealed that the chaos engulfing the Fort Lauderdale airport after the shooting in January — chaos that caused more than 50 injuries — was created by false reports of more gunfire and aggravated by authorities who struggled to manage the situation.

The months-long investigation found, among other things, that TSA screeners abandoned their posts; a swarm of police officers terrified passengers and clogged the emergency radio system; airport leaders were unable or unprepared to assist thousands of stranded travelers nearly an hour and a half after the gunman was captured, false reports of gunfire swept through the airport — some from law enforcement officers themselves.

The story includes an interactive graphic that allows readers to hear police radio transmissions from the crucial first seven minutes.
