First thing occurred to me was, Thailand, language and culture barrier (I don't care how good your translator is), so the "confession details" and their points, ie pick up from school, drugged etc, didn't faze me. I think he did it. I think we try and apply "normal" thinking when talking about this kind of personality and you can't. By the way, I can't remember Christmas 1996, and in a family where there are divorces, multiples marriages, cross country moves, I think one would find it hard to remember details of a holiday ten years old. Also, I have flown on Christmas Day. Would'nt it be possible to fly out of Ala, land in Boulder (Denver) and do this terrible thing and get out of town? This guy likes his frequent flyer miles. I also think the teddy bear and STBC are significant. As far as his connections to the Ramsey's, also very possible. He could have been a tutor for them or someone close to them.
Corps were already having computer conference calls at that time. Even my little, teeney company did that. Also, lends the possibility of a private jet to Colorado.
Since he would spend most of the time with the kids, he didn't have a lot of public exposure and no paper trail........except, MAYBE....a disbursement on an Old Tax Form for "services".
I'm sure many, many people have come forward AND, I think they have the right guy.
Palm print.....I'm sure our guys overseas got both DNA and a palmprint while they were tailing him. The palmprint could have been transmitted IMMEDIATELY to the States. Additionally, I believe the note has fingerprints.
