LOS ANGELES (AP) -- UPDATE: Law enforcement officials say a man carrying a note that said he wanted to "kill TSA" used a semi-automatic rifle to kill one Transportation Security Administration officer and wound two others today at Los Angeles International Airport.
The gunman, who was dressed in fatigues, was wounded in a shootout with airport police and taken into custody. His condition has not been disclosed.
The FBI and Los Angeles Airport Police identified the gunman as 23-year-old Paul Ciancia of Pennsville, N.J. He had apparently been living in Los Angeles. An official says Ciancia had at least five full 30-round magazines on him.
The slain security worker, 39-year-old Gerardo Hernandez, was the first TSA officer killed in the line of duty in the 12-year history of the agency, which was founded in the aftermath of 9/11.
A New Jersey police chief says the Los Angeles airport shooting suspect had apparently made references to suicide.
Pennsville Chief Allen Cummings says Paul Ciancia's father called him early Friday afternoon saying another of his children had received a text message from the suspect "in reference to him taking his own life."
Cummings says the elder Ciancia asked him for help in locating Paul, according to Cummings. The chief says he called Los Angeles police, which sent a patrol car to Ciancia's apartment.
There, two roommates said they had seen him Thursday and that he was fine.
Cummings says he told Ciancia's father that because of the son's age, he couldn't take a missing persons report. He says his department had no dealings with the younger Paul Ciancia.
A law enforcement official speaking on condition of anonymity identified the suspect as the younger Ciancia.
A law enforcement official tells The Associated Press that the suspect in the Los Angeles airport shooting is a 23-year-old man from New Jersey who wrote a rant about killing Transportation Safety Administration workers.
A law enforcement official, who was briefed at LAX on the investigation but not authorized to speak publicly, said the gunman was wearing fatigues and carrying a bag containing a hand-written note that said he "wanted to kill TSA and pigs." The official requested anonymity because he was not authorized to speak publicly.
The official identified him as Paul Ciancia. A second law enforcement official confirmed the identity, speaking on condition of anonymity.
Authorities say the suspect killed a TSA employee in the shooting.
A gunman armed with a semi-automatic rifle opened fire at the Los Angeles International Airport, killing a Transportation Security Administration employee and wounding two other people.
Tim Kauffman, a spokesman for the American Federation of Government Employees in Washington, confirmed Friday that a TSA officer was killed.
He says the union's information comes from their local officials in Los Angeles.
The attack frightened passengers and disrupted flights nationwide.
