Las Vegas gunman booked Chicago hotel overlooking Lollapalooza, report says

CHICAGO -- Stephen Paddock, the gunman in the Las Vegas massacre, booked two rooms in the Blackstone Hotel overlooking Lollapalooza, according to TMZ.

The Blackstone Hotel is located at 636 S Michigan Ave, directly across the street from Chicago's Grant Park where the annual musical festival is held.

Paddock booked one room for August 1, 2017 -- two days before the festival started. He booked a second room for an August 3 arrival. Both rooms had a checkout date of August 6, when Lollapalooza ended.

Paddock requested a room with a view, but never showed up for his reservation, according to TMZ sources.

A spokeswoman confirms to WGN that a person matching the name Stephen Paddock reserved a room at the Blackstone Hotel in Chicago in August during Lollapalooza.

"We can confirm that a reservation was made under the name Stephen Paddock, however authorities have not confirmed that this is the same person as the Las Vegas shooter. We are cooperating with the authorities on this matter," the statement said.

Chicago Police Department Spokesman Anthony Guglielmi issued the following statement:

"We are aware of the media reports and have been in communication with our federal partners. As you saw earlier this week the city conducts extensive public safety planning and training around major events, in close coordination with our law enforcement partners, to ensure public safety."
