I'm inclined to think so, at least for the subset of mass shootings that excludes gang/drug/domestic violence.
The contagiousness of suicide is backed up by research, and media coverage is a major risk factor (which even has an impact of the method that copycats use to commit suicide). Even if not all mass shooters are suicidal, intuitively it makes sense that there would be the same sort of viral effect.
