On the evening of October 1, 2017, at the close of the 3-day Route 91 Harvest Festival in Las Vegas, Nevada, a shooter, who had transported an arsenal of 23 firearms to his 32nd-floor suite at the Mandalay Bay hotel overlooking the venue, smashed out 2 windows and repeatedly raked the concertgoers below with indiscriminate bursts of semiautomatic weapons fire. The death toll from this rampage shooting climbed to 59 gunshot fatalities (58 gunshot victims and 1 shooter suicide), the highest single-shooter incident in US history and second only to the 2011 shooting massacre that resulted in 69 deaths in Utøya Island, Norway.
