I agree with you, 100%. There is NOWAY this DA, after 10 years of the Boulder PD and DA's office taking it on the chin, would spend the time and resources to get the FBI and ICE involved to pick up a guy 1/2 way across the world without some damned good solid evidence.
When you also consider California has open arrest warrants against him and Colorado was able to get their arrest done first, that tells me something.
I've been wondering if this might be some of the evidence they've kept to themselves, as LE always does on open cases.
I wonder how many unknown "tidbits" there are in that file. I bet there are some interesting items, indeed.
Tomorrow (OK later today-ugh) I will wake up to even more bizarre tales of John-I-have-man-boobs-Karr. Of that I am certain.
