In the case of the UCC shooter I do not believe so. I believe it is far more likely that autistic mom and autistic son shared an autistic obsession about guns. Autistic son had headbanging stim. Autistic Mom who was studying to be a nurse went crazy with the perscription meds to control the headbanging. One day, kid loses control, takes 6 guns out of the collection of more than 20, goes and shoots up the nearest gun-free zone he knows about, which happens to be the college he's enrolled in.
Seems very straightforward to me.
