L.A. Now Live: Discuss the latest on the LAX shooting

Discuss the latest on the Los Angeles International Airport shooting at 9 a.m. with Times reporter Kate Mather.

The man accused of going on Friday’s deadly shooting rampage through LAX remained heavily sedated and under armed guard at a hospital Monday.

Paul Anthony Ciancia, 23, an unemployed motorcycle mechanic, was wounded by LAX police as he shot his way through Terminal 3 shortly after 9 a.m. Friday, authorities said. Ciancia was shot four times in the head and a leg and is heavily sedated, the Associated Press reported.

A Transportation Security Administration agent, Gerardo Hernandez, 39, was killed, and two other TSA agents and at least one civilian were wounded during the shooting rampage. Hernandez was the first TSA agent to be killed in the line of duty since the agency’s formation in the aftermath of 9/11.

Federal prosecutors on Saturday filed a murder charge against Ciancia as they pieced together a possible motive.

Ciancia moved to Los Angeles about 18 months ago, said Allen J. Cummings, a friend of Ciancia’s father and the police chief in Pennsville Township, N.J., where Ciancia grew up. There had been no indication that Ciancia was struggling, Cummings said, or that he may have harbored anti-government sentiments.

“We don’t really know what happened out West,” Cummings said. “We don’t know where he got his ideas or where that came from.”

The gunman was carrying a signed, handwritten note in his duffel bag that said he wanted to “instill fear into their traitorous minds,” said David Bowdich, special agent in charge of the Counterterrorism Division in the FBI‘s Los Angeles office.

“His intent was very clear in his note,” Bowdich told reporters Saturday. “In that note he indicated his anger and his malice toward the TSA officers.”
