"Unrelated" room alarm leads security right to Paddock: The Las Vegas
Sheriffs Department indicates that security was originally led directly to the floor that Paddock was shooting from by a "door alarm" that was set off by someone three rooms down from him . Now, authorities have been forced to admit that this alarm and the confrontation between security and Paddock took place BEFORE he began his shooting spree. This means that police should have been alerted to Paddock's presence and exact location in advance of the attack. Who set off this alarm which conveniently helped to give away Paddock's position early, and why?
