Analysis of Recent Mass Shootings
Everytown For Gun Safety conducted a comprehensive analysis of every mass shooting between January 2009 and July 2015 that was identifiable through FBI data and media reports. This report describes the 133 mass shootings – almost two per month that occurred in 39 states in the nearly seven-year period. Each description includes the location of the shooting, number of people killed and/or injured, and information on the shooter, gun(s), ammunition, and gun purchase, where available.
There was a noteworthy connection between mass shooting incidents and domestic or family violence. In at least 76 of the cases (57%), the shooter killed a current or former spouse or intimate partner or other family member, and in at least 21 incidents the shooter had a prior domestic violence charge.
