(Reuters) - Clark County Sheriff Joseph Lombardo on Friday presented a third version of the timeline of events for the Las Vegas gunman who killed 58 people and himself in the deadliest mass shooting in modern U.S. history. [nL2N1ME0EB]

Police said Friday that a security guard was shot about the same time that Stephen Paddock, 64, began strafing an outdoor concert on Oct. 1 from his 32nd-floor suite of the Mandalay Bay hotel on the Las Vegas strip, not six minutes before as police reported on Monday. [nL2N1MK1CM]
Critics have questioned why Paddock stopped firing and why it took police so long to get to his room. [nL2N1ML1Y1]

TIMELINE:

9:59 p.m. - Mandalay Bay Security guard Jesus Campos, checking on an open-door alarm, encounters barricaded door adjacent to the door of Paddock's room on the 32nd floor.

10:05 p.m. - First shots fired by the suspect. This is seen on closed-circuit television from the concert venue. This is also around the time Campos is shot.

10:12 p.m. - First two Las Vegas Metropolitan Police Department officers arrive on 31st floor and announce gunfire is coming from directly above them.

10:15 p.m. - Last shots are fired from the suspect, according to video shot by a body-worn camera.

10:17 p.m. - First two officers arrive on 32nd floor.

10:18 p.m. - Campos, who earlier alerted hotel security, tells police he was shot and gives them the exact location of the suspect's room.

10:26-10:30 p.m. - Eight additional officers arrive on the 32nd floor and begin to move systematically down the hallway, clearing every room and looking for any injured people. They move this way because they no longer hear the gunfire of an active shooter situation.

10:55 p.m. - Eight officers arrive in stairwell at the opposite end of the hallway nearest to the suspect's room.

11:20 p.m. - The first breach is set off and officers enter the room. They observe the suspect down on the ground and see a second door that can not be accessed from their position.

11:27 p.m. - The second breach is set off, allowing officers to access the second room. Officers quickly realize there is no one else in the rooms and announce over the radio that the suspect is down.
