LOS ANGELES -- A man carrying a note that said he wanted to "kill TSA" pulled a semi-automatic rifle from a bag and shot his way past a security checkpoint at Los Angeles International Airport on Friday, killing one Transportation Security Administration officer and wounding two others, authorities said.
The gunman was wounded in a shootout with airport police and taken into custody, authorities said. His condition was not disclosed.
The attack at the nation's third-busiest airport sent terrified travelers running for cover and disrupted more than 700 flights across the U.S.
, many of which were held on the ground at LAX or not allowed to take off for Los Angeles from other airports.
The TSA late Friday identified the slain officer as Gerardo I. Hernandez, 39. He is 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.
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 one-page 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.
