A revised chronology given by investigators for the Las Vegas massacre is intensifying pressure for police to explain how quickly they responded to what would become the deadliest mass shooting in modern U.S. history.
Two hotel employees had called for help and reported that gunman Stephen Paddock sprayed a hallway with bullets, striking an unarmed security guard in the leg, several minutes before Paddock opened fire on a crowd at a musical performance, killing 58 people and injuring nearly 500 others.
At 10:05 p.m. Paddock began his 10-minute deadly barrage into the crowd, firing off more than 1,000 rounds, police said. Police didn’t arrive on the 32nd floor until 10:17 p.m., which is two minutes after he had stopped firing.
Questions remain about what happened in the six minutes between the time police say Paddock fired off 200 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.
