In one of the frequent press updates this week, Las Vegas Police Sheriff Joseph Lombardo said hotel employees are believed to have entered the room several times over the weekend and found nothing suspicious.
They said a piece of paper found in the shooter's hotel room had calculations scrawled across it determining ballistic trajectories that would help the gunman maximise his death toll.
All of this and Paddock's motive remains a mystery - no criminal history, no political agenda, and no connections to terrorism.
The reserved hotel rooms overlooked the festival's main stage, entrance, and exit - not vastly different than the positioning of the Mandalay Bay suite he eventually used to attack innocent Route 91 festival goers.
Her attorney, Matt Lombard said, "It never occurred to me in any way whatsoever that he was planning violence against anyone".
Minutes after the shooting began, a hotel security guard showed up outside his suite and Paddock shot him in the leg. She voluntarily flew back to the USA from the Philippines Tuesday night and met with the Federal Bureau of Investigation for hours of questioning. While there, he wired me money, which he said was for me to buy a house for me and my family. Through her lawyer, Danley insisted she thought this was Paddock's way of preparing her for a breakup.More news: Thiago 'thrilled' with World Cup qualification after 2014 heartache
"I know that she doesn't know anything as well like us", said one of the sisters, who chose to remain anonymous.
He said that it was only logical to "make the assumption" that Paddock had "some help at some point" in pulling off Sunday's massacre, pointing to Paddock's huge arsenal, explosive materials found in his vehicle and his meticulous planning. There is no evidence that Paddock's act was an act of terror.
Law enforcement says Paddock had stockpiled 47 guns since 1982 and bought 33 of them over the past year alone.
Lombardo said Wednesday that more than 30 of those guns were purchased in the past 12 months, suggesting an event in his life may have triggered him to stockpile weapons.
