Unfortunately, this isn't the first school-shootings rundown we've had to assemble. Our original post, published on April 20, 2009, the tenth anniversary of the massacre, counted 108 school shootings following Columbine. Including incidents noted in a 2012 update, shared after the December 2012 killings in Newtown, Connecticut, and a 2015 post published after the horrific mass shootings at Umpqua Community College in Roseburg, Oregon, there have been another 100 since then.
What follows are brief descriptions from a comprehensive Wikipedia page about school shootings, with four of them having taken place in Colorado post-Columbine.
As you'll see, not all of these shootings resulted in multiple casualties. In some instances, there were no injuries or fatalities. 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.
Here's the roster, starting with Columbine and continuing through Parkland.
Columbine High School massacre: 18-year-old Eric Harris and 17-year-old Dylan Klebold, students at Columbine High School, killed twelve students and one teacher. They injured 21 additional people, and three more were injured while attempting to escape the school. The pair committed suicide at the end of the massacre.
