He's not a fake because he is recognized world-wide for his accomplishments. I think Morrisey has a burr in his butt over the Tim Masters case. As far as not being able to take away what someone doesn't have, Kolar doesn't have a case against Burke; there is that.
Kolar is tiptoeing a fine line. He doesn't seem to have the freedom to present his complete case for fear of being sued. I don't think anybody can know 100% who did it because the other two witnesses were complicit. However, when one studies all the evidence and has a thorough knowledge of this case, they begin to put the pieces together. Why would she lie about this? Why did he mislead us about that? Why would she stay with him? Why would he stay with her? All these questions, and there are a million of them, are pieces to a puzzle and the can only fit together one way, and as far as I can tell, the answer is always Burke.
For instance, You could theorize that John did it when JB threatened to out him for sexual abuse. Not a bad theory. But then you would have to explain why Patsy would cover for him. You'd have to explain why a marriage that was rocky at best, could endure this? You'd have to explain why a man that obviously had access to plenty of adult woman would abuse his daughter, yet there was nothing in his history to remotely suggest that he was sexually attracted to children. So the theory may be good, but when you peel back the layers there is absolutely nothing to support it. Time to start again.
The only scenario that I see as viable is that Burke did it. As you peel back the layers here you find more and more things that make you shake your head. You find more and more questions. Why was he do indifferent? Why did they work so hard to hide his medical records? Why did they lie about him being on the 911 call? Why did they lie about him being asleep? Would each parent risk everything to help their only remaining child?
