Blogging takes a strange turn...
This is just too creepy for words. I remember hearing something about this case on the evening news. Just one of those stories you listen to in the background while eating dinner.

Then I read this story online about how law enforcement had been monitoring this person through his blog. Check out the link in the story, Blogger is still hosting it:
Wired News: Cops Watched Sex Offender's Blog. Go back a few months and you can read all about his dementia.

I spent a few years working in forensics back in the 1980's. I had the bone-chilling job of reading through the journals found in a couple of cases, which had been entered as evidence. My skin crawled as I noticed some similar patterns to this guy's blog.
