Ciancia, 23, is a Los Angeles native who reportedly has no connections to the airport, and is not, as was suspected, a former TSA agent. The suspect may have had strong anti-government views, based on writings he was carrying with him at the airport.
He is believed to be in critical condition at UCLA Medical center.
One person, a TSA officer, was shot and killed and at least three other TSA personnel were injured Friday morning when a shooter entered Terminal 3, firing a semi-automatic weapon. Security officers responded immediately, returning fire and injuring the suspect.
