Only a severely paranoid person would take the time to write a year's worth of blog entries on the off chance he became a fugitive. Even then, what advantage does it give him? Some misdirection, certainly, but simply disappearing would be just as effective.

Occam suggests he IS writing the blog entries, and I'd say the GPS coords are accurate via the same reasoning.

And looking at the bigger picture, his behaviour suggests he was intimately involved in the murder. I don't know much about Belize's police force, but I would be surprised if he was at a greater risk of death by cooperating with them than by going on the run - particularly with his fame.

In fact his behaviour reminds me most of Charlie Sheen's drug-addled antics last year. Sad to see someone fall so far.
