The most severe mass shooting by number of fatalities in United States history occurred on October 1, 2017, when Stephen Paddock shot into a crowd of concertgoers on the Las Vegas Strip. He killed 58 people and injured 546 others, then took his own life before authorities could apprehend him.

Most recently, one of the worst mass shootings in the U.S. occurred in Maine on October 26, 2023, when Robert Card, an Army reservist and firearms instructor, opened fire in a bowling alley and a bar, killing 18 and injuring 13 others. Card then became the focus of a two-day-long manhunt, until he was found dead from a self-inflicted gunshot.
