The gunman who authorities said killed at least 59 people at a Las Vegas music festival appears to have used at least one rifle outfitted with a device that allowed the weapon to fire at a rapid rate, and had nearly two dozen firearms in his hotel room, law-enforcement officials said. Investigators found 23 firearms in a room on the 32nd floor of the Mandalay Bay Resort and Casino. The weapons included AR-15-style and AK-47-style rifles as well as a large cache of ammunition, two law-enforcement officials said.
