Chris Jean saved his two friends, and himself. He told ABC of his escape from the club:
"I opened the door and I made sure there was no-one outside waiting for us so they could shoot us.
"I grabbed one of my best friend's hands and I tried to grab the other one also but he was so traumatised he just kept standing around. Then I opened the door, that's when I started running, but I made sure the door was wide open for others.
"Everybody was just laying on the floor, trying to duck. Some people ran to the bathroom also but for me, my first reaction was to just open the door and then just to run out."
This Twitter user tweeted his location in the hopes that police would find him.
A witness, Luis Burbano, told CNN about helping someone else at the events.
“I saw he had a bullet wound in his arm and side,” he said.
“So I ripped my shirt to make a tourniquet and stop the bleeding. He was Jacksonville, so I was talking to him, trying to keep him awake.
“I saw another guy and he was trying to get back in to look for his friend. He had, I kid you not, a bullet sticking out of him. So I ripped my shirt again.
“Then we were told to get away from there.”
At the scene, Brandon Wolf was also tweeting about the events. He has since described what happened, and called for gun control after discovering his two best friends passed away.
As it currently stands, 49 people died at the scene (not including the gunman, which takes the count up to 50), and 53 people were injured. The horrifying incident was the biggest mass shooting in US history.
