I followed this case EVERY single day from the very beginning up until my mother got sick June 22 2009. So I know I have missed a lot, so please no one attack me. I agree the letter is very poorly written and amateurish especially for someone claiming to be a scientist. However have these addresses been checked for Zeniada, Jeff Hopkins and Juilette. I am not even going to say anything about what this person claimed about the forensics, but if any of the other things mentioned should come up to be true and not well checked by authorities, it may cause serious problems for the state and create reasonable doubt. Look at what happened in the OJ trial.... You have to remember all it takes is one person believing they may not have followed through and Casey could walk. If there are all these KC supporters out there writing letters starting blogs and all that, one of these brainless dimwits could also be placed on the jury..
Just food for thought, Nothing is a sure thing, I thought the OJ trial was a sure thing but he is free today.
