The TSA said he was the first in its history to die in the line of duty. A second TSA employee was wounded in the attack before LAX police confronted a shooter they say is 23-year-old Paul Anthony Ciancia and wounded him with their own gunfire:

It happened at 9:20 a.m. in Terminal 3 when, police said, a suspect pulled an AR-15-like assault-style rifle out of a bag, went up an escalator, approached a passenger screening area, and “shot his way through to the Terminal 3 gate area,” the LAX police union said in a statement.

Officers were on the case with “seconds,” police said, and shot and wounded the gunman at the back end of the terminal near a Burger King, according to authorities and reports.

The L.A. Fire Department now says five people, including Hernandez, were taken to hospitals as a result of their injuries.

A Harbor-UCLA Medical Center doctor said the TSA agent, a behavioral detection officer, arrived “without signs of life” and that medical staffers were unable to revive him despite more than an hour of effort.

Hernandez was reported to be a husband and a father of two, a son and daughter.

Suspect Ciancia lived in a Los Feliz apartment, CBS Los Angeles reported tonight. He reportedly moved to L.A. from his hometown of Pennsville in Southern New Jersey about a year and a half ago.

The police chief there said he had contacted L.A. authorities after Ciancia's family expressed concern that Ciancia might be suicidal. The LAPD is reported to have conducted a “welfare check” on Ciancia this morning, but he was said to have not been home.

The Associated Press reported that the 23-year-old had a note in his bag that said he wanted to “kill TSA and pigs.” He is reported to have anti-government views.

Ciancia was in custody in the the hospital and was in unknown condition tonight.
