According to the call logs, Orlando police dispatch first received a call about shots fired at the LGBTQ nightclub just before 2:03 a.m. on June 12. After that, more calls came flooding in.
Some of the first callers were hiding — one in a closet and one upstairs. Dispatchers could hear gunshots over the phone.
Dispatcher logs indicate gunshots seemed to be getting closer.
At 2:09 a.m., a dispatcher wrote, "hearing 20-30 gunshots. Heard female screaming." Seconds later, another dispatcher logged, "My caller is no longer responding, just an open line with moaning."
It wasn't long before family and friends of those trapped inside called 911. A father told dispatchers he heard from his daughter who was shot in the arm and leg and was hiding in a bathroom.
Callers inside the nightclub last reported hearing gunshots at 2:18 a.m. Shortly before 3 a.m., a dispatcher wrote, "Subj is saying that he is a terrorist and has several bombs strapped to him in the downstairs female bathroom."
By 5 a.m., Orlando Regional Medical Center said it had received 40 shooting victims. Three other victims had been transported to other hospitals. Within a minute of that report, the logs show SWAT entered the nightclub.
According to the Orlando Sentinel, the most recent inspection records indicate at least one of the nightclub's exits was blocked by a vending machine. The inspection was completed about three weeks before the shooting.
The shooting claimed the lives of 49 victims and injured 53 others. It is considered the deadliest mass shooting in modern American history.
