Still catching up, but interesting that he has some "Peeping Tom" in him..which reminds me of the following post I just composed during my nap (seriously). I hope I can remember it and explain it as clearly as I did to myself earlier:
So, we have seen in many abduction and murder cases where an older perp is arrested, and one of our first questions is usually "What else has this monster done?" (my words exactly actually in Gabbi Doolan's threads, and many others, for example pertaining to RAT and Kibby (whose abodes I was also reminded of when I saw the pics of the Unabomber's and RD's residences)...Anyway:
Re the concept of escalation, with an older "rampage shooter" such as RD, is it possible that like abductors and murderers, their crimes become more brazen...in other words, what other "similar" crimes, perhaps less bold but still possibly relating to shooting and killing, might RD have committed?
In the NoCo threads, we have been discussing various possible profiles of various possible shooters. I've learned that there are "spree shooters", "rampage shooters", then patient sniper types...one area of interest for me has been trying to learn where these classifications potentially blend as far as psychological profiling, etc goes.
