LAS VEGAS (AP) — A gunman perched high on the 32nd floor of a Las Vegas Strip casino unleashed a shower of bullets down on an outdoor country music festival below, killing at least 50 people and wounding more than 200 as tens of thousands of frantic concert-goers screamed and ran for their lives, officials said Monday. It was the worst mass shooting in modern U.S. history.
