Las Vegas shooting

Las Vegas sheriff says at least 50 dead, 200 wounded at outdoor concert

UPDATE: 7 a.m.: Clark County Sheriff Joseph Lombardo has raised the attack's toll to more than 50 dead and more than 200 injured, making it the deadliest mass shooting in U.S. history. Our original report is below.

At least 20 people were killed at an outdoor music festival on the Las Vegas Strip by what's believed to have been a lone gunman firing from the 32nd floor of the nearby Mandalay Bay Resort and Casino. More than 100 others were wounded, Clark County Sheriff Joseph Lombardo said early Monday. The shooter, described as a local resident, was killed, but police are searching for his female companion.

Witnesses at the Route 91 Harvest Music Festival said they heard popping noises, then a pause, followed by rapid-fire automatic gunfire, and saw muzzle flashes from an upper floor of the Mandalay Bay hotel. Limited flights have resumed at the adjacent McCarran International Airport.
