An Examination of the Role of Perpetrator’s Relationship to Overall School Shooting Casualties

High-profile school shootings in recent years have fueled fear and uncertainty among stakeholders (e.g., parents, teachers, and students) and the public debate on gun control legislation nationwide. These fears are reflected in the public discourse and the academic community, which focuses their investigation on rampage school shootings. To address this gap in the empirical literature, the current study’s goal is twofold: (1) to contribute to the descriptive understanding of school shooting characteristics; and (2) address the gaps in the extant literature through examining the perpetrators relationship with the school on the total number of victims during a school shooting incident. Secondary data analysis was performed on the K-12 School Shooting database (K-12 SSDB). A negative binomial and descriptive analysis were conducted on the K-12 School Shooting database, established by the Naval Postgraduate School’s Center for Homeland Defense and Security (CHDS) in 2018, which has been recently updated to reflect recent incidents. The findings and policy implications of the findings are discussed in detail in the manuscript.
