This is the blog of Duncan, the man that had kidnapped Shasta, the little girl who's family was murdered. You must read it from the earliest to latest postings on this page to fully realize the deterioration of his mind. Now, this could have been carefully calculated so that he would have a ready-made defense of insanity, but he has so perfectly depicted the degeration of the paranoid schizophrenic mind it's creepy. He is so classically paranoid schizophrenic...
Also, read the comments to the blog. (well, at least the first page or so) They are absolutely infuriating.
