Secondly, garage records show that "during a period when Paddock's auto left the hotel garage", one of his key cards was used to access his room.
They believe a note found on a nightstand in Paddock's hotel room contained a series of numbers that helped him calculate a more precise aim, accounting for the trajectory of shots being fired from that height and the distance between his room and the concert, a law enforcement official said Saturday.

Las Vegas killer Stephen Paddock's brother once threatened to kill a friend in California, TMZ reported.
The Boston Red Sox, who have a home playoff game Thursday against the Houston Astros, also released a statement about the new reports, according to CBS Local.
In the days following the horrific shooting, it was reported that Paddock, who was found dead shortly after the massacre, had been planning to attack concert-goers at the Life Is Beautiful Festival, which was headlined by Chance The Rapper.
FBI Deputy Director Andrew McCabe said he was surprised Paddock had provided so few clues, and that has proved challenging.
