A TSA officer told him to "grab my stuff and go." But then the officer noticed Saryan, who was on the floor, didn't have his shoes.
"He grabbed the shoes, and the two of us started running down the corridor toward the gates," Saryan said.
That's when the gunman shot the TSA officer, Saryan said. "He got a grazing wound."
Saryan hid in a corner and watched as the shooter "calmly walking down the corridor" toward him.
"He said, 'TSA?'" Saryan said.
"I just shook my head, and he kept going."
What is that sound?
Chuck Ocheret was at Gate 30 at Terminal 3, walking toward the food court, when he heard "a couple of popping noises."
Initially, it didn't register to him and others near him that it was gunfire. "It didn't sound like gunfire," he said.
Then, he turned around.
"There was a stampede of people coming my way, and I realized something was ... wrong," Ocheret said.
"People were screaming, 'Run into the bathroom, get behind something,' " he said.
Ocheret picked up his carry-on bags and ran down a long corridor toward the "point-of-no-return" exit.
"It's a long run when you think you could have a crosshair on your back," he said.
'Getting knocked down'
Alex Neumann was at a food court, waiting to travel to Miami, when he heard the shots.
"People were running and people getting knocked down. There was luggage everywhere," Neumann said. "Mayhem is the best I can describe it."
Several police officers moved about the airport with guns drawn, he said.
'Hid underneath the plane'
Tory Belleci and Grant Imahara, stars of the Discovery Channel's "Mythbusters," were waiting for a flight to Delaware that had been delayed when they heard the shots and saw people start to run.
"It didn't register until everybody started, like, flying down the hallway and they were just jumping over chairs, jumping over people, hiding, and we were kind of trapped at the end of the terminal," Belleci told CNN.
A security guard eventually opened an emergency door. "We all piled out onto the tarmac, and just kind of a hid underneath the plane," Belleci said.
While Belleci was on the tarmac, Imahara was locked down in the Virgin America first class lounge.
"Virgin promptly locked the lounge doors. About ten minutes later, LAPD armed with automatic weapons arrived to secure the area," Imahara wrote in a post on Twitter.
Four hours later, the two men were still waiting to leave the airport.
