Timeline: The deadliest mass shootings in the US

Three of the deadliest mass shootings in the United States’s modern history have occurred since October 2017. 

In February 2018, a gunman opened fire at a high school in southeastern Florida, killing at least 17 people and injuring more than a dozen others. 

In early November 2017, at least 26 people were killed in a mass shooting during a church service in Sutherland Springs, Texas, making it the “largest mass shooting in state history”, Governor Greg Abbott had said. 

The shooting came about a month after Stephen Paddock opened fire on concertgoers at the Mandalay Bay Resort and Casino on the Las Vegas Strip, killing 58 people and injuring more than 500 others. 

The three shootings are among the deadliest in the US since 1949.
