Given the relative lack of psychiatric information and data on the perpetrators of US mass shootings, the aim of our study was to understand who these "mass shooters" were and whether they had a psychiatric illness. If so, were they competently diagnosed, and if so, were they treated with appropriate medication for their diagnoses before the violence?
