Trauma, Suicidality, and Crisis
Suicidality was found to be a strong predictor of perpetration of mass shootings. Of all mass shooters in the The Violence Project database, 30% were suicidal prior to the shooting.

Those numbers were significantly higher for younger shooters, with K-12 students who engaged in mass shootings found to be suicidal in 92% of instances and college/university students who engaged in mass shooting suicidal 100% of the time.

The data indicate, however, that nearly all persons who engage in mass shootings were in state of crisis in the days or weeks preceding the...

The research team cautioned that the qualitative data, from five interviews, did not lend themselves to generalization, because each individual’s story is unique. There was no single profile of a person who engaged in a mass shooting, but the interviewed mass shooters shared the following traits: 1. Early childhood trauma and exposure to violence. ...
The database used open source data, leaving room for bias, the researchers noted, because the source data were originally gathered for different purposes. Media outlets have their own biases, in terms of coverage of different mass shootings. Generally, the report noted, certain categories of mass shootings tended to attract the most coverage. They ...
