Oh, I don't think so. Mary Lacy is a smart DA, if there is proof this guy wasn't in Boulder in 1996 she isn't going to prosecute him. I think she knows something we don't. Fact is Karr's family has yet to prove he was with them in 1996 and Mary Lacy may know for a fact he was in Boulder in Christmas of 1996. She is not going to prosecute someone she can't get a guitly verdict on, no way!
Who would want the book and movie rights if he wasn't guilty?......Who would read a book about an innocent person?....DO they already know something?
I tend to think you must be right. I can't see how she would do this if she hadn't proven he was there. Depending on what kinds of records he left, it may be trivial for LE to locate him in Boulder on the night of the murder. So, I tend to think she's got him as far as him being in Boulder.
