I ask that authorities handle my disposal – Carnell Marcus Moore"

 A Beaumont man shot and killed Thursday at Houston's George Bush Intercontinental Airport was a reserved person of few words, neighbors said. Hearing the gunfire, a Homeland Security Investigations agent came out of his office and confronted Moore, ordering him to put down the gun, Smith said. The agent fired once, and Moore shot himself - apparently at the same time, according to Smith. Moore was dead at the scene. Tricia Bentley, a spokeswoman for the Harris County Institute of Forensic Sciences, said an autopsy was expected to be performed on Friday. Nearby at the McDonald's in the food court, employee Tiffany Rigmaiden heard two shots, then shouting, then three more shots. ET 
 
 HOUSTON 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 during an incident that sent people in the terminal scrambling and screaming, police said Thursday.
– The gunman who was killed—possibly by his own hand—at a Houston airport yesterday left a number of chilling posts on Facebook the day before, prompting CBS News to suggest he was planning a mass shooting. But a note he was carrying, discovered after he was shot, said he'd opted to drop a larger plot and kill himself, KHOU reports; the note cited a "monster within." Suspect Carnell Moore, 29, entered Bush Intercontinental Airport's Terminal B yesterday, where he sat down and shot two rounds at the ceiling with a pistol, CBS reports. That's when a Homeland Security special agent told him to drop his gun. Moore didn't, says a Homeland Security spokesman, per the Houston Chronicle. He turned to face the agent, who shot Moore just as he was shooting himself, CBS notes. A suitcase next to him held a loaded AR15 assault rifle; his car contained more ammunition. Among his earlier Facebook posts was one on Wednesday: "I recently had the chance of staring death in the face, and she was beautiful." Later that night, he wrote, "This Life Will Crash Tomorrow!"
