GUNS DON'T KILL PEOPLE, OR DO THEY?

[ZEROSPHERES]

THEORY: Campos was sent up to investigate a signal of a door ajar on floor 32. Casino central on the ground floor electrically monitors entry and exit doors to all stairwells on all floors. So far reports won't say what door but I have seen speculation it was to another guest's room on that floor and was just a lucky coincidence bringing unwanted attention to Paddock's plans. I theorize it was to the stairwell on floor 32 and it was Paddock who messed with it to allow accomplices access without using the elevator that would have recorded them.. This stairwell is one of three doors at the end of the hall where Paddock rented his suite and an adjoining room with its own hallway access. The stairway door occupies the left side and is immediately across from the door to his smaller room where the room service cart was parked. The double door to his suite is between the stairwell door and the door to the smaller room and is on a wall perpendicular to these other doors. The cart had a camera so he could see the hall including the stairwell door.
Theorizing, he did not act alone and the stairwell door was violated to allow his cohorts access to the floor without being documented riding in the elevator it is also possible he was murdered by an accomplice before or after the shooting upon the concert. The shooting upon the concert was the objective but he thought he was there for some other reason. The shooting lasted only 9 minutes. That is a full hour before the room was breached. It gave the accomplice time to escape down the stairs and out to the street.
