LOS ANGELES (AP/CBS) - 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 shooting at Los Angeles International Airport prompted a heavy police response and the evacuation of Terminal 3.
According to CBS Los Angeles, a person reportedly carrying a high-powered rifle was shot and secured by authorities.
