UPDATE OCT. 12 2 P.M.: With information coming from the Las Vegas Metropolitan Police Department, the Federal Bureau of Investigations, and other independent sources, MGM Resorts International has decided to release a statement regarding their knowledge of the timeline of events surrounding the Las Vegas Route 91 music festival.
Although we prefer not to comment on the details of the investigation, we are issuing this statement to correct some of the misinformation that has been reported," said MGM Resorts. "The 9:59 p.m. PDT time was derived from a Mandalay Bay report manually created after the fact without the benefit of information we now have. We are now confident that the time stated in this report is not accurate. We know that shots were being fired at the festival lot at the same time as, or within 40 seconds after, the time Jesus Campos first reported that shots were fired over the radio. Metro officers were together with armed Mandalay Bay security officers in the building when Campos first reported that shots were fired over the radio. These Metro officers and armed Mandalay Bay security officers immediately responded to the 32nd floor. We will continue to work with law enforcement as we have from the first moments of this tragedy as they work toward developing an accurate timeline."
The LVMPD is planning to clarify the timeline surrounding the mass shooting on Oct. 13.
UPDATE OCT. 12 11 A.M.: Las Vegas police say they'll have an updated and more complete timeline on Friday. Until then, the video above breaks down the timeline of events surrounding the Route 91 mass shooting as they currently stand.
ORIGINAL STORY: Mandalay Bay staff did not call Las Vegas police until after Stephen Paddock had already begun firing on the concertgoers, according to "World News Tonight" on ABC.
Their information comes from an anonymous source who has reviewed records from the hotel-casino.
According to the report, Mandalay Bay staff did not call police when security guard Jesus Campos reported internally that someone was shooting on the 32nd floor. Nor did they call police when building engineer Stephen Schuck also reported internally that someone was firing at him on the 32nd floor.
About six minutes after shots were fired inside the hotel, Paddock began firing outside at the crowd, according to Sheriff Joe Lombardo.
MGM Resorts spokesperson Debra DeShong wrote in a statement on Tuesday that the company does not believe this timeline is accurate:
This remains an ongoing investigation with a lot of moving parts. As evidenced by law enforcement briefings over the past week, many facts are still unverified and continue to change as events are under review. We cannot be certain about the most recent timeline that has been communicated publically, and we believe what is currently being expressed may not be accurate.
We understand the public’s desire for information and the importance of getting our community and the public at large the information they deserve, and we are doing everything we can to support law enforcement’s efforts to do so. Therefore, it is not appropriate for us to comment further at this time on what remains an open matter for law enforcement.
