A gunman perched on the 32nd floor of a Las Vegas hotel-casino unleashed a hail of bullets on an outdoor country music festival below, killing 59 people as tens of thousands of concertgoers screamed and ran for their lives, officials said Monday. It was the deadliest mass shooting in modern U.S. history.
At least 515 others were injured in the Sunday night attack, authorities said.
SWAT teams using explosives stormed the gunman's hotel room in the sleek, gold-colored glass skyscraper and found he had killed himself, authorities said. The gunman , identified as Stephen Craig Paddock, a 64-year-old retiree from Mesquite, Nevada, had as many as 10 guns with him, including rifles, they said.
Asked about the motive for the attack, Sheriff Joseph Lombardo said: "I can't get into the mind of a psychopath at this point."
The sheriff said a check of federal and state databases showed Paddock was not on law enforcement authorities' radar before the bloodbath.
