His right side was next to the opening of the shower in the final, seated photo.

I think if the attack had gone as planned, and all the "mess" was contained within the shower, then there would not have been her bloody palm print in the hallway with her blood mixed in, or her hair pulled out in a struggle. I also think if things had gone as planned, there would not have been a huge mess to try and clean up, and she would have been less frantic, and she would have remembered to either take the whole camera with her, or at least the memory card.
In that case, all the truly damning evidence against her would not have existed. She would have been a suspect, but I doubt they would get a conviction with the circumstantial evidence only. No matter how strong Travis' family was. I think there is a good chance she would have just gotten away with it.
