I am intrigued with your 10 degrees of separation theory, which changes the victimology on this case quite a bit and actually adds to the strangeness of this crime. I was thinking more like 3-4 degrees at most, when I wrote my profile of him the day before he was captured. But you may well be right. It makes all kinds of sense. He was thinking that would add a lot to his "I don't want to be caught" pile. Chilling to think he intended to go ahead and collect his Ph.D. and then - what? Work for the FBI? Work at a university teaching criminology? Yikes.
I don't think he'll get away with an insanity plea, but you're right - he may try one. He's certain to be seen by a psychiatrist as part of his booking process in Moscow, but it may evolve into a situation where the court orders him to be observed psychiatrically.
It's amazing how he has morphed physically over the years. To my way of thinking, he turned himself into a scary looking person. Appears to have no close friends, no mention of a girlfriend at all by anyone so far.
I'll add to the list of factors that he had on his checklist of "not getting caught" that he killed outside his residential jurisdiction and then fled to yet another jurisdiction. I believe he had no pre-murder accomplices whatsoever. He had every reason to be talking about crime to others, and he may have sought advice in that matter or vetted his theories with other students, under the guise of discussing a particular case. He may have been involved in online forums regarding crime (in fact, I would assume he was).
What grandiosity this dum-dum had. I do wonder what his thought processes were like as he realized, from across the nation, that MPD and the FBI were onto him, major league, big time onto him.
I love that the FBI and PA LE got a warrant, broke a window in a door, and entered the house at 3 am.
