School Shootings in 22 Years Since Columbine: 284 and Counting

Twenty-two years ago today, on April 20, 1999, two seniors at Columbine High School killed twelve students and a teacher before taking their own lives in an appalling episode that changed the way law enforcement officials from coast to coast deal with mass shootings, as witnessed by the response to the attack on a Boulder King Soopers last month. But while temporary facility closures and transitions to remote learning prompted by the COVID-19 pandemic have slowed the carnage, school shootings continue to happen with disturbing regularity.

At least 284 school shootings have taken place in the United States since the Columbine massacre, including 44 in the past two years.

Our most recent school shootings list, published in April 2019 following widespread school closures across the metro area because of concerns about a Florida woman obsessed with the Columbine slayings who was later found dead, counted 240 school shootings in the prior twenty years, as documented on a crowdsourced Wikipedia page that's the most comprehensive roster we've found. Of the additional 44 shootings now on that same source, all but five happened prior to shutdowns prompted by the novel coronavirus. But with more schools now open nationwide, the pace appears to be picking up again. Three school shootings have taken place in the last three months, including one in Tennessee last week.

Moreover, the total is likely even higher. For instance, the list doesn't include the August 28, 2018, shooting outside DSST Cole Middle School that severely injured one student. Denver police saw the incident as gang-related, but it would certainly seem to qualify for inclusion anyway, considering that school was in session and the attack took place just prior to 2 p.m. And if this shooting wasn't counted, it's likely that others were missed around the country.

Not all of these episodes resulted in injuries, but plenty of them did — including the STEM School Highlands Ranch assault in May 2019. And the proliferation of mass shootings in recent weeks only adds to fears that the downturn in school-based attacks won't last much longer.

Here are the 44 school shootings since April 20, 2019. Click here to see the previous 240.
