(TMZ) -- Below is the startling bird's-eye view the Las Vegas shooter would've had from the Chicago hotel he booked just days before Lollapalooza kicked off.
TMZ broke the story ... the shooter booked two rooms at Blackstone Hotel, located across the street from Grant Park, the festival's venue. As TMZ reported, the hotel room had clear views of all the stages and the main entrance.
TMZ has learned the view is from the 20th floor, taken earlier this year while Lollapalooza was in full swing. TMZ has told the shooter didn't have an assigned room but specifically asked for a room with a view.
The murderer is responsible for the Las Vegas massacre. He never checked in to the Blackstone.
