Three mass shootings have rocked the U.S. in the past 17 months — and they have been some of the nation's bloodiest.
That grim statistic was reached Sunday when a gunman opened fire at a small and humble place of worship in Texas, leaving at least 25 people dead.
The shooting at the First Baptist Church in Sutherland Springs, a rural stretch of land about 35 miles from San Antonio, comes just a little over a month after the country's worst massacre when Stephen Paddock gunned down 58 people at an outdoor country music festival from a Las Vegas hotel.
And less than a year and a half ago, Omar Mateen, a 29-year-old security guard, killed 49 people and wounded 58 others at a gay nightclub in Orlando that was hosting a Latin night on June 12, 2016. Mateen was killed by police. At the time, the Pulse shooting was the deadliest terror attack in the U.S. since 9/11.
Here are a number of other U.S. shooting sprees (not a comprehensive list):
