Keep thinking about that picture on the back porch where she's down. How the hell did she fall? From her position, it almost looks like she fell UP the steps. I'll have to think about it a bit more.
I have already looked at that, side by side with the last pic of her standing up... It appears to me that from the pic where she's looking down into her purse to the pic of her lying down, the rug on the second step has been moved on the side closest the house.
I surmised that she stepped down with her bare foot onto the rug and when she went to step with her clod hopper foot to the third step her right foot hung up in the rug and she fell backwards..
The part of the rug where her right foot would have first stepped appears to me to be flipped forward.. And you can see by how far her legs are hanging out that she was at least going to the third step...
I'm pretty sure that somewhere in the CBS story it says she did not fall at all.
