Here’s a list of every school shooting over the past 50 years

Jason Cato

Over the past 50 years, there have been nearly 250 school-related shootings across the United States, a Tribune-Review analysis found.

That includes more than 130 since the 1999 incident at Colorado’s Columbine High School — a massacre that left three dozen people dead or injured which often is used as a baseline in reporting school shootings.

As the Washington Post reported , a leading group that tracks school shootings and that is frequently cited counted the Valentine’s Day 2018 mass shooting at a South Florida high school as the 18th such incident this year nationwide.

In reality, it was the fifth, the Washington Post said.

Everytown for Gun Safety , a nonprofit advocacy group, explained that its criteria for a school shooting is “any time a firearm discharges a live round inside a school building or on a school campus or grounds.”

The group since has amended its list under a tighter set of rules.

The Tribune-Review used its own research and set of criteria for its list, which includes incidents going back 50 years to 1968. The list includes:

• Shootings that happened on or near school campuses while classes were in session.

• Shootings where students were present, such as ones on school buses or at school-sanctioned functions, such as athletic events and dances.

The Trib’s list does not include suicide-only incidents or shootings that occurred on or near school campuses when classes were not in session or at times students otherwise were not present.

Shootings on college and university campuses are included in a separate list using similar criteria.

TribLIVE commenting policy

You are solely responsible for your comments and by using you agree to our Terms of Service.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
