Stephen Paddock before the shooting

At 10:05 p.m, Paddock shot numerous rounds into the crowd at the Route 91 Harvest Festival from his room on the 32nd floor of the Mandalay Bay Resort and Casino, authorities have said.

Sheriff Lombardo said his department's initial account was "not completely inaccurate", and called the adjustments to the timeline "minute changes" that are common in a complex investigation.

Las Vegas police officer David Newton told CBS News program "60 Minutes" on Sunday that he entered the room and saw a note on the shooter's night-stand with numbers that appeared to be created to help his aim.

Lombardo made the clarification at a news conference Monday about the ongoing investigation into the shooting and the possible motives for Paddock's October 1. killing spree.

"You really don't understand, until you see rows of personal belongings left behind" by those who fled the scene, the magnitude of the event, Lombardo said poignantly. He reminded surprised journalists he had cautioned them that, in their "zest for" quick facts, some facts could change as the investigation progressed.

During a press conference held on Monday evening, Lombardo said investigators have not been able to hone in on any one particular event that might have caused Paddock to open fire on the crowd.

Some of the casinos along the Las Vegas Strip dimmed their marquee signs for about 10 minutes Sunday to pay tribute to the victims who spent that much time under fire October 1 in the Las Vegas shooting.

Meanwhile, an employee of Paddock's told ABC News Monday that he was a man who cared about people, but a prostitute he frequently hired claimed he had violent sex fantasies and bragged he was "born bad".

The sound echoed in his window, he said.

"He never said anything to me or took any action that I was aware of that I understood in any way to be a warning that something terrible like this was going to happen", she said in a statement.

In addition, Lombardo said Paddock's motives were still unclear and there was no evidence that he had been motivated by any ideology.

Officer Newton told 60 Minutes the room, which was filled with dust and flashing lights from an explosive used to blast open the door, was something straight out of a movie.

Conrade said the the second breach rattled his hotel room.

"As I've said from Day 1, we want to figure out the "why" to this, and we'd like to know the motive", Lombardo said.

Police initially said the guard interrupted Stephen Paddock as the attack was under way.

The 32-135 suite in Mandalay Bay hotel from where Stephen Paddock, 64, opened fire on an outdoor festival in Las Vegas. The FBI, Red Cross, and city and county officials are doing an "amazing job" on that front, Lombardo complimented, calling it "not an easy task to undertake".

Investigators believe the numbers represented calculations for more precise shots, according to a law enforcement official who wasn't authorized to discuss the details of the ongoing investigation publicly and spoke on condition of anonymity.
