This seems rather simple, unless there really is evidence not known to the public or 1000 private investigators concerning this awful crime.

This guy, Karr, bailed to Thailand because he was facing child porn charges here in the U.S. With more than a few screws loose, including a self deluded belief that a cover of investigating Jon Benet for a book would throw off any suspiscion he was an active pedophile, this guy continued contacting this professor by e-mail. Why? Because he is an irrational pedophile bent on his own guilt and need to satisfy his unnatural urges. Most likely obsessed with the imagery of the Ramsey child, he unknowingly hung himself with his own rope (as most criminals eventually do)by implicating himself by mistake (hundreds of e-mails about the same topic, Jon Benet? - weird). I'm thinking this whole Jon Benet connection is bogus and only an excuse for this freak to plea insanity to cover his continuing pedophelia. He probably figured he would just continue his abuse until he got caught, make up same extraordinary story, and play "crazy" to explain his behavior. Why would his wife lie about him being with her at the time of the murder in Alabama? Alabama isn't exactly next door to Colorado. See where I'm going with this?
