Anthony Ciancia, a 23-year-old LA resident, has been named by the FBI as the suspect in the shooting at Los Angeles International Airport (LAX)on November 1.
Gerardo Henandaz, an unarmed agent of the Transport Security Administration (TSA), was killed and a number of people were wounded.
The gunman managed to get deep into Terminal 3 of LAX before pulling out an assault rifle from his bag and starting to shoot.
The gunfire created pandemonium in the airport terminal, with people running for safety and taking cover where they could.
One witness described what happened, saying: “I heard gunshots and we all just went down to the ground and a few seconds later I saw him coming up the elevator and walk by about 10 feet away from me with his gun pointed.”
Another person said: “You just don’t believe it’s real, it’s like seeing something on TV, you can’t believe you’re the one hiding behind a counter, it just doesn’t seem real.”
There are reports that the gunman was carrying materials expressing anti-government sentiment and may have been specifically targeting the TSA.
