Hun, you posted this exact message on this board a few months ago... only with a different screen name and situation. This has been around for a long time and will continue to be around for a lot longer. If anything the screen name will change and the number of victims will vary by a few bodies. If you have doubts about any of these things, just google them. You'll be surprised by what you get. Secondly just use your common sense to disect the message. If they know the screen name he uses they can easily track that name down to the last computer it logged into and they would have caught him by now. 4 or 5 murders is one thing, but 56 - thats just pushing it even for Hollywood? Finally and most obviously, if a person commits 3+ murders, he's a serial killer. If he kill 5+ at the same time, he's a mass murderer, dont you think you would have heard about this on the news long before he got to number 8? Check out
