Correlates of the Number Shot and Killed in Active Shooter Events

Active shooter events have captured the public’s attention since the Columbine High School shooting in 1999. Although there has been research on various aspects of these events, only a single study has attempted to identify factors that are related to the number of people injured or killed in these events. This study was limited in that it only considered the presence or absence of a semi-automatic rifle. This paper expands on the existing research by examining several other factors that may impact the total number of people shot or killed during active shooter events.
