LOS ANGELES - Authorities Saturday were trying to discover what motivated a man, armed with an assault rifle, to shoot his way through a Los Angeles International Airport terminal checkpoint Friday, killing a security agent, wounding at least two more and threatening travelers, before being shot by police and taken into custody.
Patrick Gannon, chief of the Airport Police Department, said the suspect -- identified by the FBI as 23-year-old Paul Anthony Ciancia -- walked into Terminal 3 around 9:20 a.m. Friday, pulled an assault rifle out of a bag and started shooting. The weapon was believed to be an AR-15 assault rifle.
Gerardo I. Hernandez, 39, a father of two from Porter Ranch, was gunned down inside the terminal that houses airlines such as Allegiant Air, Frontier, Spirit, Virgin America and JetBlue. His name was confirmed by a Transportation Safety Administration official and reported by multiple media outlets. Hernandez was a "behavior determination officer" who just transferred to LAX from Montana. He was the first TSA agent to die in the line of duty, officials said.
Ciancia is a New Jersey native who was living in the Los Feliz area until February, when he moved to Sun Valley, according to ABC7. His family contacted authorities before the shooting asking them to have police in Los
Angeles check on him because he had reportedly threatened suicide, according to news reports.
"He proceeded up into the screening area where TSA screeners are and continued shooting," Gannon said, adding that the gunman "went past the screeners and back into the terminal itself."
Gannon said airport police pursued the suspect, who was shot and taken into custody inside the terminal.
Ciancia was being treated at Ronald Reagan UCLA Medical Center, according to news reports, but no details about his medical condition have been released.
Los Angeles Fire Department paramedics treated six people at the airport, and five were taken to area hospitals. One person apparently declined to be transported, fire officials said.
Mayor Eric Garcetti said at least three people were shot. FBI officials said some of the people injured were apparently hurt trying to escape the gunfire.
The Transportation Security Administration issued a statement saying "multiple" TSA officers were injured, "one fatally." According to Craig Harvey of the coroner's office, the victim died around 11 a.m. at Harbor-UCLA Medical Center.
The hospital's Dr. David Plurad said the man (Hernandez) had no signs of life when he arrived at the hospital. He was suffering from "multiple" gunshot wounds to the chest and abdomen. Plurad said at least one bullet apparently fragmented, causing more extensive internal injuries. J. David Cox, president of the American Federation of Government Employees, the union that represents TSA officers, said the victim (Hernandez) was a "behavior determination officer" who had just transferred to LAX from Montana.
Harvey said the coroner's office had not been notified about any other fatalities stemming from the shooting.
A second patient was treated for minor shoulder injuries at Harbor-UCLA Medical Center. Officials at Ronald Reagan UCLA Medical Center said they treated three male patients, one in critical condition and one in fair condition. It was unclear if either was Ciancia. The third patient was also brought to the hospital in fair condition and was released by mid-afternoon, according to the hospital.
One of the patients at the hospital is Brian Ludmer, 29, a teacher at Calabasas High School, Las Virgenes schools Superintendent Dan Stepenosky told the Los Angeles Times. He was waiting for a flight when he was shot in the leg and then dragged himself to a closet where he hid until he heard a police officer outside the door, the newspaper reported.
Another patient was believed to have been taken to Marina del Rey Hospital.
Some media outlets reported that Ciancia was carrying a hand-written message saying he wanted to kill TSA agents, although federal and local authorities would not confirm the reports. Media reports from his hometown of
Pennsville, N.J., indicated the suspect's father had contacted police Thursday saying he was concerned his son was planning to commit suicide.
Some initial reports indicated that a second suspect had been arrested, but Gannon said, "This was a lone shooter," and the gunman "was the only person that was armed in this incident."
Mayor Eric Garcetti said the shooter had a large supply of ammunition and could have done far more damage had he not been arrested.
"There were more than a hundred more rounds that could have literally killed everybody in that terminal today," he said. "If it were not for their (police officers') actions, there could have been a lot more damage."
David Bowdich, FBI special agent in charge of the Counter-Terrorism Division for Los Angeles, said that in addition to the TSA agent who was killed, at least one other agent was wounded by gunfire.
"There are additional injuries, some of which seem to be potential evasion injuries where they may have injured themselves trying to get away," he said.
Bowdich said Terminal 3 was expected to remain closed as investigators continued combing through the building for evidence.
LAX officials said Friday evening the airlines in Terminal 3 had canceled all flights to or from Los Angeles for the rest of the day.
A total of 1,550 flights with an estimated 167,050 passengers were affected, and 86 flights scheduled to arrive at LAX were diverted to other airports, said airport spokeswoman Nancy Suey Castles. The carriers were working to transfer operations to other terminals, but travelers should expect flight delays and cancellations, she said, adding that passengers should contact individual airlines for updates.
Bowdich asked that anyone who might have information about the shooting or the investigation to call an FBI tipline at (888) 226-8443.
The FBI also issued a statement saying it had not made any determination about whether the shooting had any connection to terrorism.
"It would be premature to comment on a motivation at this time and joint investigators have neither ruled out terrorism, nor ruled it in," according to the FBI.
FBI spokeswoman Laura Eimiller told City News Service the Bureau has agents stationed permanently on site at LAX and handle all criminal matters at airports.
"Those procedures are in place because there are obvious concerns about an attack at the airport and today we are also dealing with the murder of a federal employee," Eimiller said.
Eimiller also said no decisions have been made yet regarding the charges that Ciancia, the alleged shooter will face -- be they federal or state charges -- should he recover from his shooting wounds. The Bureau, she emphasized, is also still exploring all possibilities related to Ciancia's motive for the shooting, including, terrorism, attempted suicide by cop, or some other pathology.
President Barack Obama told reporters in Washington, D.C., that he had been briefed on the shooting and was "concerned about it."
The outbreak of gunfire sparked chaos inside the terminal, as passengers, some with children, hit the floor to avoid the gunfire and scrambled to evacuate.
A witness told KNX radio that people began scrambling to evacuate the terminal when the shots rang out. She said some people were directed out through emergency exits onto the tarmac until they were picked up by buses and taken to another terminal.
Airline passenger Dana Starfield told KCAL9 she and other passengers hid in a closet at the terminal after the shots rang out.
"We were all just texting our families where we were," she told the station. "... I just let them know where I was and that I was OK."
Another witness told a Wisconsin radio station that the gunman walked past him and asked him if he was with the TSA. The witness said he shook his head no, and the gunman moved on.
Hundreds of passengers were evacuated out of terminals as police searched the airport throughout the day. Crowds of passengers could be seen packed into other terminals, standing on sidewalks or lining streets around the airport.
Starting at 4 p.m., Friday, shuttle vans and buses were allowed on the lower level as airport operations slowly resumed. By 6, the upper level was reopened and all the terminals except number 3 were open for business.
The shooting was the first of its type at LAX since 2002, when an Egyptian-born Irvine resident opened fire at the El Al ticket counter on the Fourth of July.
El Al employee Victoria Hen and Yaakov Aminov, who was at LAX to see a friend off, were killed and several other people were injured before the gunman -- Hesham Mohamed Hadayet -- was shot dead by an El Al security officer.
The airport was also the source of security concerns last month when a pair of dry ice bombs exploded in areas not accessible to the general public.
Two employees of an airport contractor were arrested and charged in connection with those explosions, which did not cause any injuries.
