HOUSTON - Police say a man who had fired a gun inside a ticketing area at Houston's largest airport was killed after being confronted by a law enforcement official.
Houston police Capt. Dwayne Ready says it's unclear if the unidentified man fatally shot himself or was killed by a Homeland Security agent who had confronted him at Bush Intercontinental Airport
Ready says the agent confronted the gunman after the man had fired one shot into the air around 1:35 p.m. Thursday and had refused to drop his weapon. Ready says the agent fired at the gunman at the same time as it appeared he was shooting himself.
Officials say an autopsy will be conducted on Friday.
Airport officials say the terminal remains closed but the rest of the airport is still operating.
Witnesses told ABC13 they heard a couple of gunshots ring out and a TSA agent told everyone to get down.
Dale Howard, of Tomball, was at the baggage handling area of the airport waiting for his sister to arrive on an incoming flight when he heard two shots fired from the floor above. A few seconds later, he said he heard three more shots.
"People were screaming. I knew exactly what it was -- gunfire," Howard said.
The FAA issued a ground stop for all flights at IAH.
