Exactly!
Another thing that has nagged at me from the beginning is his call to 911 after he found her body. His comments to the operator when she asked him if Allison was still alive: "I didn't touch her" "I didn't do anything".
How could one be so 'collected' after such a gruesome discovery finding your loved one brutally murdered. Why would your answers be ones that indicated you were not responsible? That seems very strange to me.
I don't think if you had just found the love of your life brutally murdered you would be thinking of preserving the crime scene, or not touching the body because someone might think you did it. I would think you would want to check to see if she was still alive no matter how much blood there was.
I can't even imagine not checking, no matter what the circumstances!
No, not typical behaviors.....
Regardless of what I saw, I would have called an ambulance...not the police.
