The man charged with killing a Transportation Security Administration officer and wounding two other agents and a civilian during a shooting rampage at Los Angeles International Airport made his first court appearance Wednesday, still showing signs of the gunshot wounds suffered when he was arrested.

Paul Ciancia hadn't been seen in public since the Nov. 1 attack that created chaos at one of the nation's busiest airports and affected air travel around the country.

The 23-year-old spoke in whispers and showed no emotion during the 10-minute hearing in the West Valley Detention Center in Rancho Cucamonga, about 45 miles east of Los Angeles. He's being housed at the facility in federal custody.

U.S. Magistrate Judge David Bristow asked the diminutive, slender Ciancia if he understood the charges against him.

"Yes," responded Ciancia, who was shackled at his hands and feet and had a bandage on his neck and bruises on the left side of his face.

His lawyers didn't comment on his injuries.

Airport police responding to the rampage shot Ciancia four times, including once in the mouth. He was hospitalized for more than two weeks before being placed in federal custody.
