Stephen Paddock had booked two rooms at Chicago's Blackstone hotel overlooking an expansive downtown park where the popular Lollapalooza music festival took place over four days in August, according to the website TMZ and NBC News.
Police in Chicago in the US state of IL are investigating into media reports that the Las Vegas mass shooting gunman reserved two rooms at a hotel overlooking Lollapalooza music festival crowds in downtown Chicago in early August. Lollapalooza was attended by 400,000 guests, including Malia Obama, and was headlined by acts like Chance The Rapper, Lorde, and The xx.
They say Stephen Paddock rented rooms in high-rises overlooking the Lollapalooza festival in Chicago in August and over the Life is attractive festival near the Vegas Strip in September.
Further information about Las Vegas shooter Stephen Paddock is slowly coming out in the days since the deadly shooting Sunday.
In a statement, the Blackstone emphasized that no one by the name of Stephen Paddock actually stayed in the hotel during the Lollapalooza run.
Authorities believe Paddock had stockpiled weapons and ammunition over decades, and meticulously planned the Sunday night's attack.
Sheriff Lombardo said investigators were also looking for possible accomplices who helped Paddock assemble his arsenal.More news: Gunman from hotel perch kills 59, wounds 527 in Las Vegas

NBC News, citing anonymous former Federal Bureau of Investigation officials, reported that Ms Danley said she remembered him laying in bed and moaning and that investigators are looking at the possibility he may have been in "physical or mental anguish". However, Paddock never checked into the rooms.
The official said no evidence has been found that Paddock ever came to Chicago that weekend.
This wasn't the only festival he considering targeting before ultimately carrying out the attacks this week. He then shot and killed himself as police tried to break into the room.
Discerning Paddock's motive has proven especially baffling as he had no criminal record, no known history of mental illness and no outward signs of social disaffection, political discontent or extremist ideology, police said. "That's the one in this one, and we are not there yet", FBI Deputy Director Andrew McCabe said.
"There's all kinds of things that surprise us in each one of these events". It was unclear if Paddock was in Chicago during the festival, according to the law enforcement official, who was not authorized to discuss the case publicly.
Authorities discovered Paddock's interest in the two cities by examining his communications and electronic equipment, NBC News said.
