Then you are accusing the MIL of lying under oath. That was directly from the trial testimony.
She was staying in a motel, and would spend most of the day helping with the children. That woman PLANNED to murder those children.
There is no question that she was thought to be "nuts" by the people around her...and was being treated.
It's probably her history of mental problems that saved her rear. Wouldn't surprise me if that idiot Rusty wasn't trying to get her pregnant again.
Why was her MIL staying in a motel?
I'm not trying to change your mind and you aren't going to change mine, so I' going to bed.
Yep, she was sane enough to do this in the less than one hour between the time RY left for work and her MIL scheduled to show up. She was also sane enough to immediately call the police and confess.
