LAS VEGAS, Nv. (AP) - A revised chronology given by investigators for the Las Vegas massacre is intensifying pressure for police to explain how quickly they responded.
Two hotel employees called for help and reported gunman Stephen Paddock sprayed a hallway with bullets and struck an unarmed security guard in the leg.
Police say that was several minutes before Paddock opened fire on a crowd at a musical performance, killing 58 people and injuring nearly 500 others.
Questions remain about what happened in the six minutes between the time Paddock fired rounds through the door of his 32nd-floor suite into the hallway of the Mandalay Bay hotel and casino and when he unleashed a deadly hail of gunfire into the crowd at a the Route 91 Harvest festival.
