Gunman Kills TSA Officer At LAX; Suspect In Custody

A gunman walked into Terminal 3 at Los Angeles International Airport Friday morning, pulled an assault rifle out of a bag and opened fire, killing a Transportation Security Administration officer at a security checkpoint and wounding multiple other TSA officers, authorities and law enforcement sources said.

The information was preliminary and could change as the incident is investigated.

Law enforcement sources tell CBS News the suspect was wounded in the incident but survived and is in custody. Preliminary information indicated that the suspect may have been an off-duty TSA employee, but a federal official told CBS News the suspect was not a current or former employee of the agency.

Airport police Chief Patrick Gannon told reporters during an afternoon news conference that the gunman pulled an assault rifle out of a bag and began to open fire inside the terminal.

"He proceeded to go up to the screening area and continue firing," Gannon said.

The gunman then engaged in with authorities past the checkpoint and was successfully taken into custody after what Gannon described as an "officer-involved shooting."

"We believe at this point that there was a lone shooter, that he acted alone in this incident," Gannon said, adding that police have completed a security sweep of the airport.

The suspect entered the terminal wearing military-like clothing when he opened fire, law enforcement sources told CBS News.
