On October 1, 2017, a mass shooting occurred at the Route 91 Harvest country music festival on the Las Vegas Strip in Paradise, Nevada. During the closing performance by singer Jason Aldean at a packed outdoor concert, a gunman located on the 32nd floor of the Mandalay Bay hotel and casino across Las Vegas Boulevard opened fire into the festival crowd.
The shooter was identified as 64-year-old Stephen Craig Paddock, who lived in Mesquite, Nevada. He was retired accountant and divorcee with no known children. He was found dead in his hotel room with a self-inflicted gunshot wound. With at least 60 fatalities (including the perpetrator) and 527 injuries, the shooting surpassed the 2016 Orlando nightclub shooting as the deadliest in United States history.
At least 60 people were killed (including the perpetrator), and at least 527 people were injured during this shooting. Hours after the shooting, the Islamic State of Iraq and the Levant (ISIL) claimed responsibility, though this was later refuted by an FBI spokesperson as the claim lacked any credible evidence. But as yet, no clear reason for the killing has emerged.
