Me too. Of course, in his head and his lies, it was his own blood. I always felt like he was just a piece of crap that killed Mickey in a panic. I no longer think that. I think he was a very, very evil person all along.
I also don't like the eyewitness account to the scratch marks on his triceps.
One of the issues that bothered me is the nephew said there we fingernail scratch marks BEHIND his headrest. So IMO that suggest a lie in his story that Mickey was in the front seat. Sounds more like at some point she was in the back street. I always felt his story was only a minor bit of truth.
