Lone gunman kills 59, injures hundreds, in Las Vegas concert attack

LAS VEGAS – A retiree armed with multiple assault rifles strafed an outdoor country music festival in Las Vegas from a high-rise hotel window on Sunday, slaughtering at least 59 people in the deadliest mass shooting in modern U.S. history before killing himself.

More than 525 people were injured—some by gunfire or shrapnel, some trampled—in the pandemonium adjacent to the Las Vegas Strip as police scrambled to locate the assailant. Police identified the gunman as Stephen Paddock, 64, who lived in a retirement community in Mesquite, Nevada. Authorities said they believed he acted alone, though his motive was unknown.

The Islamic State militant group claimed responsibility for the massacre, but US officials said there was no evidence of that.

17 rifles were found in the room where Paddock killed himself, some with scopes and some that appeared to have been modified in an attempt to convert them into machine guns.
