Michael Adams - whos website has gotten very, very interesting lately. Apparently a bunch of his friends got tired of waiting for the police to resolve it, and got together and started investingating his disappearance on their own. Based on what they've been putting on the website it looks like they know who took Michael and have been leaving very interesting messages for them. It's like a soap, but I say good for them. It shows what people can do when they come together.
