Welcome to schoolshooters.info. This site is a compendium of resources to help prevent rampage attacks and to understand the perpetrators of large-scale school violence. The purpose of this collection is to assist professionals in education, mental health, and law enforcement, as well as anyone else who is interested, in learning about those who commit school shootings.

This site contains four types of materials: articles, edited data, original documents, and official reports. The articles and edited data are marked “Version 1.0.” Minor corrections or additions will be noted as Version 1.1, 1.2, and so on. Significant changes in a document will be indicated by labeling it Version 2.0, 3.0, and so on.

Note: Articles and resource documents are frequently added to the site. Please check back every now and then.
