solved The Investigative Assistance for Violent Crimes Act of 2012, signed

The Investigative Assistance for Violent Crimes Act of 2012, signed into law in January 2013, defines a mass killing as one resulting in at least 3 victims, excluding the perpetrator. On the evening of October 1, 2017, Stephen Paddock, a 64-year-old man from Mesquite, Nevada, opened fire upon the crowd attending the Route 91 Harvest music festival on the Las Vegas Strip in Nevada. Between 10:05 and 10:15 p.m. PDT, he fired more than 1,000 rounds of ammunition from his 32nd-floor suites in the Mandalay Bay Hotel, killing 60 people and wounding 411, with the ensuing panic bringing the injury total to 867. About an hour later, Paddock was found dead in his room from a self-inflicted gunshot wound. This incident was the deadliest mass shooting committed by an individual in modern United States history.
