2017 Las Vegas Shooting

On the night of October 1, 2017, during the closing performance of the Route 91 Harvest country music festival on the Las Vegas Strip, 64-year-old Stephen Paddock fired more than 1,000 rounds from two connected suites on the 32nd floor of the Mandalay Bay hotel into the crowd of over 22,000 concertgoers below. The shooting occurred over roughly ten minutes, between about 10:05 p.m. and 10:15 p.m. Sixty people were killed by gunfire (in addition to Paddock's suicide), and at least 413 more were wounded by bullets or shrapnel; total injuries, including those from the ensuing panic, reached approximately 867. About an hour after the shooting began, Paddock was found dead in his suite from a self-inflicted gunshot wound.

Paddock, a retired auditor and real estate businessman living in Mesquite, Nevada, had no prior criminal record beyond traffic citations. He checked into Mandalay Bay on September 25, 2017, eventually occupying two connected 32nd-floor suites overlooking the festival grounds, and brought in more than 20 suitcases of firearms and equipment with the help of hotel bellmen. Investigators later found 24 firearms in his suite, including 14 AR-15-style rifles fitted with bump stocks that allowed them to fire at a rate similar to automatic weapons, along with high-capacity magazines, hidden surveillance cameras, and a note calculating distance, wind, and trajectory to the crowd. Ammonium nitrate and other explosive-making materials were also found in his vehicle, though authorities said he did not appear to have assembled a device.

Before firing on the crowd, Paddock shot hotel security guard Jesus Campos through his suite door, wounding him in the leg; Campos and maintenance worker Stephen Schuck alerted hotel dispatch and, eventually, police. Officers reached the 32nd floor and found Paddock dead after breaching his suite with explosives at 11:20 p.m.

Multiple investigations, including a Las Vegas Metropolitan Police Department preliminary report (January 2018) and final report (August 2018), along with an FBI Behavioral Analysis Unit report (January 2019), concluded that Paddock acted alone and found no definitive motive or ties to hate groups or terrorist organizations, despite an unsubstantiated claim of responsibility by the Islamic State. Douglas Haig, an unlicensed ammunition seller whose fingerprints were found on unfired armor-piercing rounds in Paddock's suite, was charged with illegally manufacturing ammunition and later sentenced to 13 months in prison.

The attack prompted renewed national debate over firearms regulation, particularly bump stocks, which were banned by the U.S. Justice Department in December 2018 — a ban later overturned by the U.S. Supreme Court in June 2024. Victims and their families reached an $800 million settlement with MGM Resorts International, owner of Mandalay Bay, approved by a judge in September 2020. The event is commemorated through the 1 October Memorial Committee, formed in 2019, and by the Las Vegas Village site, part of which MGM Resorts later donated for a permanent memorial.
