On the night of October 1, 2017, a shooter opened fire on a crowd of concertgoers at the Route 91 Harvest music festival on the Las Vegas Strip in Nevada. He killed 58 people and wounded 422, with the ensuing panic bringing the injury total to 851. The shooter, Stephen Paddock, a 64-year-old man from Mesquite, Nevada, fired more than 1,100 rounds of ammunition from his suite on the 32nd floor of the Mandalay Bay Hotel. The shooting occurred between 10:05 and 10:15 p.m. PDT; about an hour later, Paddock was found dead in his room from a self-inflicted gunshot wound. His motive remains officially undetermined.
The incident is the deadliest mass shooting committed by an individual in the history of the United States. It focused attention on gun laws in the U.S., particularly with regard to bump stocks, which Paddock used to fire shots in rapid succession, at a rate of fire similar to automatic weapons. As a result, bump stocks were banned by the U.S. Justice Department in December 2018, with the regulation in effect as of March 2019.
