Mass shooting on the Las Vegas Strip — TIMELINE

Updated October 10, 2017 - 10:05 am

This timeline has been updated with information provided by the Metropolitan Police Department during a briefing on Monday, Oct. 9.


9:40 p.m.: Jason Aldean takes the stage as one of the last performers on the final night of the three-day Route 91 Harvest country music festival.

9:59 p.m.: Jesus Campos, a Mandalay Bay security officer, is fired upon while responding to an open-door alarm from a room down the hall from where the 32nd-floor suite Stephen Paddock was staying. Clark County Sheriff Joe Lombardo had said that Campos was fired upon after Paddock fired on the concert, but he later amended the timeline to show that Campos was shot in the leg before Paddock “shot at the outside world.”

10:05 p.m.: As Aldean sings his hit “When She Says Baby,” gunfire erupts, directed into the crowd of approximately 22,000 people attending the concert. Metropolitan Police Department officer reports shots fired from the adjacent Mandalay Bay hotel.
