It is clear to me that Adam was never properly diagnosed. Either b/c his mom didn't want him to be as it would tarnish the image to the outside world, or because he simply was not taken often enough for anyone to know. Or a combo of both.
After reading the mom's emails (ay yi yi) from 1999, it seems false image is of utmost importance. It also seems, but may not be true, that the family was extremely active with others all of the time. If all of that changed when the divorce came that could further distress Adam, who still is not properly diagnosed, nor treated. He may have been used to lots of out of the home activities with family and friends, and when it ended, he may have thought it was because of him being different, or he blamed the parents and did not like the new quiet life - until he could adjust and make it his new life of sorts.
By reports, he would stand there and not talk if not spoken to when in school, he would not make eye contact, he began self mutilating, he would not tolerate others touching him and went further to not tolerate anyone in his space at all, he refused to speak with anyone and only emailed his mother, very focused on one subject at a time, and then we have to remember any family influence throughout his life, and any (if any) genetic influence. All of this looks to me like paranoid schizophrenic - after having met a few people that truly are - and it does begin to worsen around age 14. It never gets better, it can only be treated, but still he would know he was not normal, and so would everyone else. He needed proper diagnosis and treatment. It cannot be forced on anyone though, so this is where it ended up.
A teen in a room full of shot at target left overs, gun manuals, internet acess, a home full of guns and ammo, and a mom that caves to every demand as she is in denial or simply does not want others to know the full story. A teen full of angst, hormones, family disappointments, and a mind that is not exactly like others (he may have even been seeing and hearing things by this age, but we do not know), with full rule of what he wants, when he wants it, how it wants it. A crazed King. His mother is his slave, and he a pandered slave to his every whim.
