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!"
