The Orange County Sheriff's Office has released chilling audio of the 911 calls related to June's mass shooting at the Pulse nightclub.
The calls, which were released Tuesday, are the first to be made public.
The release comes nearly three months after the massacre, in which a gunman killed 49 people and injured 53 at the Orlando, Florida, nightclub. The police killed the shooter, Omar Mateen, after he took hostages in a three-hour standoff inside the nightclub.
In the audio, terrified callers relay information to emergency dispatchers.
Many of the calls were from people who were not at the club but were calling 911 on behalf of loved ones believed to be inside.
"I understand. We are in the club. We are searching for everybody. We're pulling victims out," a dispatcher told a woman calling about her brother, who was at the club, at about 2:43 a.m. "We're still on scene. It's actively being worked, ma'am. Listen, please be patient. It's going to take a while before we figure out where everybody's at."
Some callers were frustrated after calling multiple times and seeming to get little information from the scene:
Dispatcher: "911, what's the location of your emergency?"
Business Insider reached out to the Orange County Sheriff's Office for the 911 call files.
These are just some of the calls from that night. The Orlando Police Department hasn't released its 911 calls yet and is in the middle of a lawsuit centered on that and other public records from the shooting.
The Orange County Sheriff's Office posted a warning on its Facebook page that the calls were graphic, and it provided contact information for emotional counseling:
