The hotel security guard injured by Las Vegas gunman Stephen Paddock was shot before the mass shooter began massacring the festival crowd below the Mandalay Bay Hotel and Resort, police said Monday, making a major change to their timeline of the shooting. Clark County Sheriff Joe Lombardo, who previously said the arrival of security guard Jesus Campos may have caused Paddock to stop firing on the festival audience, now says Campos was investigating a report of an open door on the 32nd floor when he heard drilling sounds coming from Paddock's room, the AP reports. The sheriff says Paddock had installed hidden cameras and started firing into the hallway when he saw Campos approaching.
Campos was hit in the leg but was still able to alert security officials to Paddock's location, Lombardo says. He says that Paddock started firing on the crowd about six minutes after shooting the guard and never completed his drilling, which may have been to install more cameras or create a hole to shoot through. The sheriff didn't explain why such a big change was made to the timeline or say how it could affect the investigation, the Las Vegas Review-Journal reports. "In your zest for information and my zest to ensure the public safety and the calming of their minds, some things are going to change," he said. (Lombardo released more new details Monday, but said police still don't know what Paddock's motive was.)
