LOS ANGELES -- The unemployed motorcycle mechanic suspected of carrying out 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 fire on him again, killing him, according to surveillance video reviewed by the FBI.
In a news conference announcing charges against Ciancia, U.S. Attorney Andre Birotte Jr. spelled out a chilling chain of events inside LAX that began when Ciancia strode into Terminal 3, pulled a Smith & Wesson .223-caliber assault rifle out of his duffel bag and fired repeatedly at point-blank range at a TSA officer who 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's duffel bag contained a handwritten letter signed by Ciancia stating he'd "made the conscious decision to try to kill" multiple TSA employees and that he wanted to stir fear in them, said FBI Special Agent in Charge David L. Bowdich.
The bag also had five magazines of ammunition.
Federal prosecutors filed charges of first-degree murder and commission of violence at an international airport against Ciancia. The charges could qualify him for the death penalty.
The FBI was still looking into his past, but said it had not found evidence of past crimes or any run-ins with TSA. The bureau said he had never applied for a job with TSA.
Authorities believe someone dropped Ciancia off at the airport. Agents are reviewing surveillance tapes to piece together the exact sequence of events, he said.
"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 suspect's screed also mentioned "fiat currency" and "NWO," possible references to the New World Order, a conspiracy theory that foresees a totalitarian one-world government.
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 shooting. Administrator John Pistole did not say if that meant 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.
"He kept to himself and ate lunch alone a lot," David Hamilton told the Los Angeles Times. "I really don't remember any one person who was close to him .... In four years, I never heard a word out of his mouth."
Authorities identified the dead TSA officer as Gerardo I. Hernandez, 39, the first TSA official in the agency's 12-year history to be killed in the line of duty.
Friends and neighbors remembered him as a doting father of two and a good neighbor who went door-to-door warning neighbors to be careful after his home in the Porter Ranch area of Los Angeles was burglarized.
In brief remarks outside the couple's home, his widow, Ana Hernandez, said Saturday that her husband came to the U.S. from El Salvador at age 15.
The couple, who married on Valentine's Day in 1998, had two children.
