I may be the one to have mentioned, I don't remember. I keep a running list (sadly) of mass shootings, active shooters, school shooters, etc. I try to locate the information about the mental state, medications they were on or prescribed, response (both public and l.e.), and how they were stopped (i.e. shot themselves, shot by l.e., confronted or shot by a CCW holder, or they gave up). It's a work in progress for sure since I am still in the process of finding out about other shootings I had never heard of or information wasn't well known.
