For Coloradans, the May 14 shooting at a Tops grocery store in Buffalo, New York, an attack that killed ten people, immediately brought back memories of the March 22, 2021, assault on a Boulder King Soopers in which ten people died. But plenty of tragedies have occurred in the state between then and now, including at least sixteen mass shootings — an average of more than one per month.

This information is culled from the Gun Violence Archive, which tracks violent episodes involving firearms across the country, including Colorado. GVA identifies a mass shooting as an incident in which at least four people are injured or killed; like another major compiler, Mass Shooting Tracker, it places no additional restrictions on what qualifies. Other organizations define the term "mass shooting" differently, as noted in a 2018 RAND Corporation report. For instance, Mother Jones counts only so-called "indiscriminate" incidents with three or more fatalities other than the death of the shooter, and excludes crimes of armed robbery, gang violence or domestic violence. Likewise, Stanford University's Mass Shootings in America database skips shootings related to gangs, drugs or organized crime, but requires just three fatal or non-fatal injuries aside from the shooter.

But those who get hung up on these distinctions are at risk of missing the larger point about the frequency of multi-victim shootings — one underscored in the August 2019 post published in the immediate aftermath of mass shootings in El Paso, Texas, and Dayton, Ohio, which took a combined 31 lives. According to the Gun Violence Archive, Colorado suffered 24 mass shootings between the site's 2013 launch and the summer of 2019. That worked out to four a year.

The pace of Colorado mass shootings over the past year nearly quadruples that number — and because such episodes are so commonplace, few become dominant media stories. Most Coloradans may have a tough time remembering many of them beyond the King Soopers shooting, despite the elevated number of people hurt or slain.

Here are the sixteen mass shootings in Colorado between the grocery store shootings in Boulder and Buffalo, in reverse chronological order, complete with dates, locations, the number of people killed or injured, and links to additional coverage.
