The Violence Project
Mass Shooter Database
The Violence Project is a nonprofit, nonpartisan research center dedicated to reducing mass shooting and violence in society by using data and analysis to improve public policy and practice.
The K-12 School Shooting Database founder David Riedman has collaborated with Dr. Jillian Peterson and Dr. James Densley to co-published six op-eds on school shootings in The Washington Post, LA Times, Star Tribune, Education Week, Sun Sentinel, and The Tennessean (USA Today).
Dr. Peterson and Dr. Densley have also published findings based on 133 cases in the K-12 School Shooting Database where more than one person was intentionally shot in a school building during between 1980 to 2019. Analysis focused on offender motive, an armed guard on scene during the shooting, and the number and type of firearms the perpetrator used. Findings of the study are published in the JAMA Open Network.
