Though it is not known if Paddock meant to target the Lollapalooza music festival, investigators are still trying to determine the motive behind the Las Vegas massacre, the worst mass shooting in modern US history that left 58 concert goers dead and over 500 injured.
Paddock, a 64-year-old Mesquite resident with no criminal background, killed 58 people and injured over 500 in what has become the deadliest shooting in modern US history. Paddock planned to check out of both rooms on an August 6 check-out, which was the day the festival ended.
The Associated Press reports that authorities have been tracking Paddock's movements prior to the Sunday shooting.
Gov. Charlie Baker said there is no evidence of an imminent threat that has anything to do with the Commonwealth, and deferred to authorities in Vegas. Lollapalooza was attended by 400,000 guests, including Malia Obama, and was headlined by acts like Chance The Rapper, Lorde, and The xx.
According to that report, Paddock, 64, booked one room at the Blackstone Hotel starting August 1, two days before the festival opened. And this hotel had a bird's-eye view of the crowd.
The Chicago Tribune later reported that the Chicago Police Department is investigating the matter.
Paddock had initially tried to book a room at the El Cortez hotel.
Citing sources, TMZ said Paddock was "forceful".
Las Vegas Sheriff Joe Lombardo said in a news conference Wednesday evening that Paddock had previously stayed at a Las Vegas high-rise condo during a music festival the weekend before the shooting.
It was not immediately clear whether the Stephen Paddock who booked the room was the same Stephen Paddock behind the Las Vegas massacre.
