LAS VEGAS (AP) -- The Latest on the mass shooting in Las Vegas (all times local):
A full two months before he opened fire on a country music concert in Las Vegas from a 32nd-floor room of a hotel and killed 58 people, Stephen Paddock booked a room at a Chicago hotel that overlooks a park where a major music festival was held that weekend, a law enforcement official said Thursday.
The official said that law enforcement found no evidence that Paddock ever came to Chicago during the weekend of Lollapalooza - a music festival that attracts hundreds of thousands of people. The official, who was not authorized to discuss the investigation of Paddock's movements, spoke only on condition of anonymity after being briefed on the investigation.
The Blackstone Hotel, where Paddock made the reservations, overlooks the main stage and other stages at Grant Park where the music festival is held every year.
Paddock's booking of the hotel room, first reported by TMZ, comes as investigators, trying to determine a motive for the Las Vegas shooting, have been trying to track Paddock's movements in the days before he opened fire from the Mandalay Bay casino resort on Sunday night.

Those seeking to know the motive of Las Vegas gunman Stephen Paddock have had little more to chase than hints and shadows.
Unlike many other mass killers, Paddock led such a private life that no one seemed to know him well, and those who did had no sense he was capable of gunning down 58 people and injuring hundreds more at a country music festival before killing himself.
FBI Deputy Director Andrew McCabe said he was surprised Paddock had provided so few clues, and that has proved challenging.
Clark County Sheriff did share on Wednesday night said Paddock had rented an apartment in another high-rise above another music festival a week earlier, though he could not say why.
And he said he felt it was unlikely Paddock could have pulled off the elaborate plan alone, though investigators have no idea who may have helped him.
