Examining Mental Health in Mass Shooters

Mass shootings are defined as shootings that cause 4 or more deaths not including the shooter (excluding those committed in connection to underlying criminal activity, such as gangs or drugs); examples include workplace shootings, school shootings, public shootings, shootings at places of worship, etc. There have been 195 mass shootings since 1966, with 1,398 reported deaths. While several factors influence mass shootings, research points to psychological, sociological, and economic influences. This analysis is over 3 separate studies, having between 172-177 shooters each with the same basic demographics, but separate focuses. Overall, the main focus is looking for patterns that could help prevent future mass shootings.
