Chicago Police Department spokesman Anthony Guglielmi would not confirm the TMZ report about Paddock's plans in Chicago, but said the department is aware of the report.
New details are being revealed about the mass shooting on the Las Vegas Strip.
Sheriff Lombardo said Paddock fired about 200 rounds of ammunition into the hallway outside his suite, wounding a security guard who had come to investigate.
The manager agreed, noting on Paddock's reservation that he should be placed in a room overlooking the park. While there are many hotels near the home of the Boston Red Sox, none have rooms that overlook the ballpark.
"They're going to be intermingled with the crowd".
Also, the weekend before the Las Vegas bloodbath, Paddock rented via Airbnb - and checked into - a condo in a 21-story luxury building in Las Vegas that overlooked the Life is lovely alternative music festival, Sheriff Joseph Lombardo said Tuesday. You have to be a very amateur terrorist to think anything like that'.
On Thursday night, thousands gathered in Las Vegas to honor one of the victims who was killed, Officer Charleston Hartfield. He had 1,600 rounds of ammunition in his vehicle, along with fertilizer that can be used to make explosives and 50 pounds of Tannerite, a substance used in explosive rifle targets.

In between, cops arrived on the 31st floor - just below Paddock - at 10:12pm and got to the shooter's 32nd floor at 10:17pm, officials said.
Officers found the suspect on the ground, Lombardo said on Wednesday evening.
As it turned out, Paddock never showed. Our sources say he then called the hotel and asked for a view room.
The same week that the Life is handsome event was set to go down, Paddock sent his live-in girlfriend, Marilou Danley, home to the Philippines to "spare her life", according to her sisters.

"She made such a great effort with the neighbourhood kids". "We all want answers".
"I felt he was rude", said Ms Page, adding he would go out of his way to ignore friendly greetings.
