I've been following this case for a while now....there are so many posts to read it can be all consuming. What a sad, sad case. Completely a mystery.
Personally, I lean towards the theory that she succumbed to the elements trying to avoid being caught by police. Being the great runner she is, I believe she got further than anyone expected at the time and her remains in the woods not too far from the road. I think she panicked when she had the 2nd accident and all she could think was that she couldn't get caught drinking and driving with everything else that had been going on. I think she likely had a head injury (based on the cracked windshield) and combined with the alcohol, she just wasn't thinking clearly. By the time the panic subsided, she was in an impossible situation due to the weather, or possibly the head injury was bad enough she died from it.
A question I have is: Is it a FACT that she was caught in credit card fraud? Is it verified anywhere or do we have to simply take Mr. Renner's word for it?
I have no opinion one way or another that Mr. Renner is good or bad in this case. I've read his blog about MM, but haven't really checked him out otherwise. Much of his blog seems gossipy, but I'm glad someone is investigating. However, anyone can have a blog and say anything they want, so I'd like to know if this particular fact has been proven with any evidence.
IMHO, I don't think Maura hit her head at all. The cracked winshield was very likely caused by the air bag being deployed. It happened to my mother when she recently wrecked. She didn't hit her head but the force of the air bag deploying left her windshield cracked.
