"As the maintenance man as well is arriving in the hallway, they have some communication and they are just riddled with hundreds of bullets at this particular point", McMahill said.
The attack was the worst mass shooting in modern USA history.
That was the same floor that Paddock, 64, had set up his cache of weapons amid his plan to fire from his hotel suite windows onto a crowd at a country music festival across the street, police said.
MGM shares rose 1.1 percent to $30.76 at 2 p.m.in NY. Fifty-eight people were killed and almost 500 were hurt. But the revised timeline shows officers would have known where Paddock was before the mass shooting even started. Campos, the security guard, was struck in the leg and injured, police said.
Previously, police had said Campos was hit after the attack on the crowd.
"Funds will be used to provide relief and financial support for him while he gets back on his feet", Rodriguez's online petition says.
What exactly happened in the six minutes between Campos' getting shot and the mass shooting on concertgoers?
Las Vegas police did not respond Tuesday night to questions about the hotel's statement or whether investigators stand behind the revised timeline released earlier in the week.
"It's definitely hard, but for someone to do something so cowardly and despicable, I'm not going to let that change my life", he said. "We can not be certain about the most recent timeline that has been communicated publicly, and we believe what is now being expressed may not be accurate".
The gunman had been drilling into the adjacent wall to the doorway, according to Lombardo.
Did the gunman's firing at the security guard speed up the timeline of the shooting?
"It's his actual normalcy that makes him a fascinating study", said David Gomez, a former Federal Bureau of Investigation profiler. "I'm not privy to that".
What has become very clear to investigators is that Paddock meticulously planned the attack.
"This individual purposely hid his actions leading up to this event and it is hard for us to find the answers to those actions", Clark County Sheriff Joe Lombardo said Monday, conceding he's frustrated.
There is still no evidence that Paddock was motivated by ideology, or that there was another shooter. "I want to go back to work". Paddock fired more than 1,000 bullets and had more than 1,000 rounds left in his room, the undersheriff said.
The FBI is working around-the-clock and a "comprehensive picture is being drawn as to the suspect's mental state", the sheriff said. "We believe he made a decision to take the lives he did and he had a very purposeful plan that he carried out". He declined to discuss the interviews, but said each one was another piece in the puzzle in this case. After identifying their items, some smiled and others hugged the Federal Bureau of Investigation agents or Red Cross volunteers who had helped them.
Eric Paddock told the Las Vegas Review-Journal that he plans to put his brother's assets in a trust that would benefit the shooting victims.
He did not describe what investigators asked him during their conversations over the weekend, according to the Review-Journal.
"I understand why people are frustrated with this because we are as well", McMahill told KNPR. "We now know that he then went over and began shooting into the crowd".
