Where is the only "witness"?

Is the main witness really in Britain? That's what he's putting on all of his blogs anyway.  If he were a principal to the case and certain aspects of the case are still pending such as forensic testing on the gun and suicide note, he should have been held here. Who let him go overseas? Is he still here?

 During the time the Sheriff claimed Stuart was in "federal protection" he had phone access, and even called a popular radio show to suddenly lament his childhood ordeal. It didn't go over well with listeners according to commentary on news article relating to the podcast. He is pushing 40 and thought the Stockholm Syndrome approach would work to keep him out of trouble, after all, he would have gotten hoisted by his own petard with the story he told. His continued online and phone activity was a dead giveaway, this is just not done when you are under federal protection, you lose your phone and internet. So now we have to assume he was never under any sort of protective custody. 

....but Stassi's narrative is that Stuart was in "federal protective custody" for the 2 days prior to court hearing and prior to the deaths, but we can plainly see he was not. So where was Stuart during those 2 days? Who was the caller that reported hearing the last shot?
