A game is my prediction. Our first clue was the word Christmas. He always spelled it Christmass or X-Mass. Who does that? Most first graders can spell Christmas. Was he telling us he was Catholic? You are very correct about his grammar and punctuation. He used colons and semi-colons, tons of commas. However, I don't think that means college as you get all of that K-12. My best guess is that he was self-educated after high school. Probably was a voracious reader from childhood and forward, but not always reading wholesome stuff. The true detective magazines and some of the comic book filth available back then come to mind. He would have been a huge consumer of the newspapers available at his local library.
One thing is very clear to me but not everyone thinks so: He was smart, not a genius but crafty. He spent a lot of time thinking about everything. He almost got caught in San Francisco but then again, if the officers had stopped him, they might be dead or he might be dead or both, but I doubt he would have allowed them to jump out on him without gunfire as capture would have meant the death penalty.
I'm also fairly convinced that as a child, he was neglected, bullied, disregarded, dismissed, rejected, and probably abused in some fashion. He would not have been popular at school or with girls. As he grew up, he was either invisible or viewed as a failure. Then you add psycho to the mix and you get a raging fire on the inside that he kept hidden. Killing and taunting was his way of getting revenge plus notoriety. I figure he walked around with a little skip in step knowing he was the real life boogey man but no one knew it. The reason he was not caught because he was the guy next door. No one suspected him and he kept a clean record.
