Update: Periodically, we've compiled rosters of school shootings that have taken place since the attack on Columbine High School — and such incidents appear to be escalating.
Our original post, published on April 20, 2009, the tenth anniversary of the massacre, showed approximately 108 school shootings following the Columbine massacre.
A 2012 update, shared after the December 2012 killings in Newtown, Connecticut, added 73 more.
Now, in the wake of the horrific mass shootings at Umpqua Community College in Roseburg, Oregon, we've crunched the numbers again, with the help of this Wikipedia page. The results: another 81 shootings, bringing the total to 262, including another one in Colorado — the December 2013 murder of Claire Davis at Arapahoe High School. And we've got to imagine we may have missed some examples of this awful phenomenon. After all, the only thing that seems to slow the pace of deadly gunfire on school campuses is summer vacation.
As you'll see, not all of these shootings resulted in multiple casualties. In a few examples, there were no injuries. But one of the things that's most shocking about the list is how little publicity many of these examples of on-campus gun violence have received. So common are school shootings that without high body counts, they're treated like typical local news. That's a sad testimony to the size and scope of the problem.
Below, see the shootings after Newtown, followed by our previous coverage, which includes the incidents since April 20, 1999.
