Sheriff Joe Lombardo released a new timeline of the events surrounding the mass shooting in Las Vegas earlier this month.
Lombardo said that MGM Resorts was correct when they said that Mandalay Bay security guard Jesus Campos was shot 40 seconds before Steven Paddock began firing on the Route 91 Festival crowd.
The sheriff still stood by the 9:59 p.m. time released earlier this week, though said the circumstances associated with that time have changed.
An entry was made in the Mandalay Bay security log at 9:59 p.m. because that was the time Campos encountered a barricaded door that was near Stephen Paddock's room.
The rest of the timeline remains the same. Paddock began firing into the crowd around 10:05 p.m., he stopped shooting 10 minutes later, and police arrived at his room at 10:17 p.m.
Lombardo also addressed the discrepancy on when Stephon Paddock checked into his room at Mandalay Bay. He said that they now know Paddock arrived on Sept. 25 and changed his registration on Sept. 28 so that his girlfriend, Marilou Danley, was included.
The sheriff also talked about two Las Vegas Metropolitan Police Department officers who were injured during the shooting.
According to Lombardo, Paddock began firing at police officers once they arrived at the festival site. Officer Brady Cook sustained gunshot wounds to his shoulder, bicep, chest, and back. (Lombardo noted that Cook wasn't shot four times - those injuries include entry and exit wounds.)
In spite of his injuries, Cook asked Lombardo if he could come back to work on Oct. 13.
Lombardo also talked about Officer Samuel Whitworth, who broke his leg while trying to help Route 91 Festival attendees escape from the gunfire. Whitworth remained at the scene in spite of his injury to make sure others were safe.
