More than 20 people were killed and more than 100 injured when a gunman opened fire into an outdoor country music festival in Las Vegas on Sunday night.
Officers have killed the sole gunman, who was on the 32nd floor of the Mandalay Bay Hotel and Casino and shooting down into the outdoor concert venue, which was across the street. The shooter was a local resident.
The shooting happened just after 10 p.m. (1 a.m. ET) when Jason Aldean took the stage during the Route 91 Harvest Country Music Festival.
