Sorry, reposting this from last night, since I was apparently too tired to make an intelligible post.
First, let me say that this doesn't even sound real... it seems like a poorly planned ARG gone wrong to me.
"The Orlando Sentinel posted a story about a double homicide. Something Awful user "West " knew one of the victims in question and so posted a thread on the forums about losing one of his co-workers to the shooting. It turned out that a fair few users on the site knew one of the victims, and so internet detectives went to work.
What they uncovered was shocking and disturbing, finding an open directory on the murderer's - forum user Bomber166, now permanently banned for murder - website full of material seemingly relating to the killings. Some suspect that the user stuck the material online for the website's members to find."
