The man accused of killing an airport security officer last month at Los Angeles International Airport pleaded not guilty Thursday to murdering a federal officer and to 10 other charges. Suspect Paul Ciancia's trial is set to start Feb. 11, but officials said that date will likely be pushed back.
Ciancia is accused of fatally shooting a Transportation Security Administration agent and wounding two other agents and a passenger in Los Angeles International Airport on Nov. 1.
Prosecutors have yet to decide whether to seek the death penalty in the case.
Airport officials said the incident began at about 9:30 a.m. Nov. 1 in the airport's Terminal 3.
A Transportation Security Administration agent was killed and three others were wounded.
The slain TSA agent was Gerardo Hernandez, who was checking travel documents when he was killed. His wife said he would have turned 40 the week after his death and described him as a "wonderful husband, father, brother, son and friend." He is the first TSA agent to die in the line of duty.
A "ground stop" was issued for planes scheduled to arrive at LAX, meaning flights destined for the airport were being held at their departure point.
Passenger Robert Perez, who was getting ready to fly Virgin Air, was taking a nap in the terminal when panic erupted.
"I heard a popping sound, and everybody was diving for cover," Perez told KCAL. "The TSA said there was a shooting in the terminal and evacuate the building."
The area around the airport was jammed with cars as police shut down roads in and out of LAX.
According to eyewitnesses, the gunman entered the terminal wearing camouflage gear and opened fire with a rifle.
Alex Neumann was at a food court, waiting to travel to Miami, when the incident unfolded. He said Terminal 2 was put into lockdown.
"People were running and people getting knocked down. There was luggage everywhere," Neumann said. "Mayhem is the best I can describe it."

A federal criminal complaint was filed Saturday afternoon charging the suspected Los Angeles International Airport shooter Paul Anthony Ciancia with two felony offenses -- murder of a federal officer and commission of violence in an international airport, U.S. Attorney Andre Birotte Jr. said.
A source told CNN Ciancia started asking one of his roommates for a ride to the airport days before the shooting, claiming he needed to visit his sick father in New Jersey, but didn't say when he needed to leave. On the day of the shooting, he demanded a ride to the airport.
Ciancia's family was becoming concerned after receiving text messages from him indicating he was unhappy. Ciancia's father called New Jersey police, who contacted Los Angeles police and asked them to check on Ciancia, according to police. He was already on his way to the airport -- police had missed him by less than an hour, U.S. Rep. Michael McCaul told CNN.
The gunman had a note that indicated the suspect made a "conscious decision to kill multiple TSA employees," according to an affidavit filed along with a criminal complaint.
The incident began when Ciancia walked up to a security checkpoint and shot a TSA officer "at point-blank range," according to the affidavit. He then went up an escalator and, upon seeing the officer apparently continue to move, came back down to shoot him again
After shooting Hernandez, the gunman continued through the terminal, firing on two other uniformed TSA officers and a passenger before he was shot by airport police, U.S. Attorney Andre Birotte Jr. said.
