The Mandalay Bay security guard who survived after being shot before Stephen Paddock opened fired in Las Vegas was pictured accepting an honorary award this week - right before he vanished Thursday night hours shy of his first press conference since the savage attack.

Jesus Campos was shown accepting an award from the International Union of Security, Police and Fire Professionals of America on Monday in an official photo first released from ABC News.

As of Friday morning, the whereabouts of Campos were unknown. DailyMail.com reached out for comment to David Hickey, president of the International Union, Security, Police and Fire Professionals of America that represent the guard, and were awaiting a response.

According to the latest timeline provided by police detailing the events of October 1, Paddock sprayed 200 rounds into the hallway on the 32nd floor of Mandalay Bay, wounding Campos in the leg, six minutes before he unleashed his barrage of bullets on the crowd attending the Route 91 Harvest Festival.

Campos, who was unarmed, survived the shooting and was scheduled to sit down for five TV interviews Thursday night, including one on Fox News, but suddenly vanished.

ABC News reporter Stephanie Wash tweeted Thursday, quoting the president of Campos' labor union: 'We were in a room & we came out & he was gone.'

The latest chronology raised a series of questions about whether officers were given information quickly enough to possibly have a chance to take out the gunman before he could carry out the bloodshed.

But according to resort officials, it was no more than 40 seconds between the time Campos used his walkie talkie to call for help and Paddock opening fire on the crowd from two windows in his suite.

Earlier in the investigation, police had said that Paddock shot through his door and wounded Campos after the guard distracted him from firing on the crowd out the windows.

Campos’ union president said the latest timeline does not dispute the assertion that the guard is ‘still a hero, saving his coworker, possibly stopping additional shots,’ reported Stephanie Wash.
