How do we know that PADDOCK shot the guard at 9:59, if the shots were through a door? How do we know it was Paddock? After the guard was shot, did he leave the area around the room? How about someone shot at the guard, killed Paddock, shot at the crowd, fled the room, police show up to a dead guy in the room. ? Maybe ran up the stairway to those upper floors (Four Seasons)?

Possible? Any videos of the hallway?
