An Exploration of Female Mass Shooters

This research note provides an exploratory examination of female mass shooters in the United States between 1979 and 2019. Specifically, this work provides descriptive statistics of perpetrator, motivation, and incident characteristics. Findings indicate female mass shooters more closely align with male mass shooters than general female homicide and mass murder offenders. The most valuable findings indicate female mass shooters are not motivated by relationship disputes, they often target the workplace, and they are more likely to work in dyads, especially when engaging in ideologically motivated attacks. A discussion of findings provides insight for mass shooting and gender scholars, as well as practitioners seeking to understand female involvement in mass shootings.
