Long time lurker, first time poster.
Still catching up on how this thread has progressed today--kudos all on some excellent sleuthing! But had to jump in and post re: DG Intelligence/ADHD/drug lab
I have severe ADHD and have read a lot about it so I think I can shed some light on a few things:
Stimulant drugs effect people with ADHD VERY differently to non-ADHD people. Ex: caffeine has no effect, I can drink a pot of espresso and go to bed. When I was in university, I had classmates who would take Adderall to let them stay up all night and study, etc. that doesn't work if you have ADHD, Adderall, etc will just help tone down the distractions and make it easier to focus at closer to a degree that non-ADHD people would experience on a daily basis.
Medication can help to manage ADHD symptoms but it in no way erases them. Think of it as having a brain that is like an out of control Ferrari,it jumps around constantly,makes wild turns, etc. medication can just put you in the drivers seat of the out of control Ferrari, it doesn't change much else.
Which is one of the reasons why the more severe the ADHD, the more likely the person will have bouts, sometimes long ones of feeling completely overwhelmed. When this happens, it has a sort if freezing effect. Similar to standing at a fork in the road and being clueless which way to go and becoming sort of immobilized as a result.
ADHD and intellect tend to go hand in hand--usual people with ADHD rank in the top 5% of the population intelligence wise. This is actually a major negative because there is a huge shame factor associated with asking for help when the thought is that if you're so smart you should be able to handle it.
ADHD causes major impulsiveness. As a result people with ADHD constantly self check and often over self check. This also sort of explains the loner thing to me because constant self checking can make it difficult to let people close enough to build meaningful relationships and with ADHD you wind up so lost in thought so much of the time that it's hard to resist spending hours alone thinking things out.
Where I'm confused is if DG was circling the L's area in his truck,that rules out an impulsive act because the extra circles would very likely kick in a self check thought along the lines of "wait a minute, what am I doing?"
If this was not an impulsive act, same difference. People with ADHD cannot handle repetitive activities such as circling a block without automatically self checking, zoning out, loosing interest, forgetting what they're doing.
Ex: I had to pick up a friend recently, couldn't find the address on my first drive down the street,turned around at the end of the block and drove back and missed the address again but this time I missed it because I had already been down the block, it wasn't new/interesting to me anymore and I forgot to look for it. I drove up and down several times and tried everything I could think to try to persuade myself to focus on finding the address before giving up, calling my friend to come meet me where I'd stopped. Totally embarrassing, it may seem like a total idiot move and it was but point is that's typical ADHD.
Other thing is DG seems like an absolute science nerd. I think it's a major stretch to think he went from cooking up amphetamines to triple kidnap/possible murder. Even the prior charges for possessing a weapon can be pretty easily explained given a) he lives on a fRm and may have wanted it to protect against wild animals and/or b) he may have wanted it for protection given who he may encounter cooking up drugs.
