An autopsy will be conducted Friday on the man who fired a gun inside a ticketing area at Houston, Texas's largest airport on Thursday, to determine whether he was killed after being confronted by a law enforcement official or he turned the gun to himself, police said Thursday. Houston Police Captain Dwayne Ready said that it was not yet clear if the unidentified man fatally shot himself or was killed by a Homeland Security agent who had confronted him. According to Ready, the agent confronted the gunman after he had fired one shot into the air around midday Thursday and had refused to drop his weapon. Ready said the agent fired at the gunman at the same time as it appeared he was shooting himself.
