Oh contraire, your post is all conjecture as well and not too well informed. She could have easily inflicted the damage on her face. The same way a mother could drive their infants into a pond and kill them and go on camera and say where they were last scene. You underestimate the sheer depravity in many people.But she did get beat up. Anything that happens after that doesn't change that one fact.
And I still have a hard time believing the husband did it. Sure, I know it happens and the women defend their man afterwards. But I just don't see it with this case.
She didn't beat herself up so she could file a lawsuit.
