In the footage's last scenes, the gunman is seen exchanging fire with one of the hotel's security officers at a stairwell doorway. Gomez said the gunman was shot in the leg, but after walking up a couple steps, the assailant walks back down to casually shut the door - almost as if he had left it open by mistake.
Later on the fifth floor, he sets part of a red hallway carpet ablaze, filling the corridor with smoke. Hotel security had already evacuated guests.
At 1:46 a.m., the gunman kicks in the door of Room 501 and goes inside. Police soon arrive, aiming the white lights on their weapons through the smoke-filled hall.
The attacker, they say, set a final fire in the room and was found dead with a gunshot wound to the mouth.
