"Jesus Campos, a security guard at the Mandalay Bay Resort and Casino, was shot by Paddock six minutes before he began shooting into a crowd of 22,000 people enjoying the country music festival down below, Las Vegas Metropolitan Police Department Sheriff Joe Lombardo said in a news conference Monday evening.

Campos was responding to an alarm going off in the hotel and ventured off to find the source, when he came across the sound of drilling.

The security guard told investigators that Paddock was drilling to an adjacent wall in the hallway — most likely to install a camera or to point a rifle — but never finished the job.

Lombardo said the alarm that went off was not connected to Paddock’s room.

At 9:59 p.m., Campos was shot in the leg after Paddock fired 200 shots into the hallway. Paddock began shooting into the crowd six minutes later, contradicting original reports that Campos’ arrival is what stopped Paddock’s mass shooting.

Between the time that Campos was shot and Paddock began shooting, Campos notified authorities of what happened, which Las Vegas Metropolitan Police Department Undersheriff Kevin McMahill said Friday was “absolutely critical” as it gave police Paddock’s exact location.

Lombardo said Monday that a maintenance worker was also on the 32nd floor at the time Campos was shot, and Campos prevented that man from also being shot or otherwise injured."

Was the "alarm" triggered when the shooter tried to prop open a stairway door for an escape?

Shot in the leg after 200 rounds fired through the door? Hell, I wouldn't be within any line of sight of that doorway.
