LOS ANGELES -- The unemployed motorcycle mechanic suspected in the deadly shooting at the Los Angeles airport set out to kill multiple employees of the Transportation Security Administration and hoped the attack would "instill fear in their traitorous minds," authorities said Saturday.
Paul Ciancia was so determined to take lives that, after shooting a TSA officer and going up an escalator, he turned back to see the officer move and returned to finish him off, according to surveillance video reviewed by investigators.
In a news conference announcing charges against Ciancia, U.S. Attorney Andre Birotte Jr. spelled out a chilling chain of events at LAX that began when Ciancia strode into Terminal 3, pulled a Smith & Wesson .223-caliber assault rifle from his duffel bag and fired repeatedly at point-blank range at a TSA officer. The officer was checking IDs and boarding passes at the base of an escalator leading to the main screening area.
After killing that officer, Ciancia fired on at least two other uniformed TSA employees and a civilian airline passenger, who were all wounded. Airport police eventually shot him as panicked passengers cowered in stores and restaurants.
Ciancia, who was hit four times, remained hospitalized Saturday, but there was no word on his condition. He was wounded in the mouth and the leg, authorities said.
The duffel bag contained a handwritten letter signed by Ciancia stating that he had "made the conscious decision to try to kill" multiple TSA employees and that he wanted to stir fear in them, said FBI agent in charge David L. Bowdich.
Federal prosecutors filed charges of first-degree murder and commission of violence at an international airport. The charges could qualify him for the death penalty.
The FBI was still looking into Ciancia's past, but investigators said they had not found evidence of previous crimes or any run-ins with the TSA. They said he had never applied for a job with the agency.
Authorities believe someone dropped Ciancia off at the airport. Agents were reviewing surveillance tapes to piece together the sequence of events.
"We are really going to draw a picture of who this person was, his background, his history. That will help us explain why he chose to do what he did," Bowdich said. "At this point, I don't have the answer on that."
The note found in the duffel bag suggested Ciancia was willing to kill almost any TSA officer.
"Black, white, yellow, brown, I don't discriminate," the note read, according to a paraphrase by a law enforcement official briefed on the investigation. The official spoke on the condition of anonymity because he was not authorized to speak publicly.
The screed also mentioned "fiat currency" and "NWO," possible references to the New World Order, a conspiracy theory that foresees a totalitarian one-world government.
When searched, the suspect had five 30-round magazines, and his bag contained hundreds more rounds in boxes, the law-enforcement official said.
Terminal 3, the area where the shooting happened, reopened Saturday. Passengers who had abandoned luggage to escape Friday's gunfire were allowed to return to collect their bags.
The TSA planned to review its security policies in the wake of the attack. Administrator John Pistole did not say if that would mean arming officers.
As airport operations returned to normal, a few more details trickled out about Ciancia, who by all accounts was reserved and solitary.
Former classmates barely remember him and even a recent roommate could say little about the young man who moved from New Jersey to Los Angeles less than two years ago. A former classmate at Salesianum School in Wilmington, Del., said Ciancia was incredibly quiet.
