LAX Shooter 'Wanted To Kill TSA And Pigs' Says Anonymous Police Source

The FBI and Los Angeles Airport Police identified the gunman as Paul Ciancia, 23, of Pennsville, N.J. He had apparently been living in Los Angeles.

A law enforcement official, speaking on condition of anonymity because the person was not authorized to discuss the investigation publicly, said Ciancia was wearing fatigues and carrying a bag containing a handwritten note that said he wanted to kill TSA employees and "pigs." The official said the rant refers to how Ciancia believed his constitutional rights were being violated by TSA searches and that he's a "pissed-off patriot" upset at former Department of Homeland Security Secretary Janet Napolitano.

Ciancia had at least five full 30-round magazines on him, said the official, who was briefed at LAX on the investigation. The official said Ciancia was shot in the mouth and leg by two airport police officers.

An eyewitness, Leon Saryan, told ABC News Radio that a "fairly young" gunman with a rifle came down a corridor in Terminal 3 and shot perhaps 20 times.

A TSA officer holding Saryan's shoes was shot and wounded, he told ABC.

Saryan said the gunman asked him, "Are you TSA?"

"He saw me. He looked at me with a quizzical look and said, 'TSA?' And I just shook my head. So he moved on," Saryan said.
