there isn't one. Patsey waited her whole life to have a little girl like Jonbenet. Patsey was in pageants her whole life and Jonbenet love them and Patsey enjoyed every minute doing pageants with Jonbenet. It was something special they did together and Patsey and Jonbenet were best friends. Patsey loved that girl more than life itself, the way a mother loves her child! No motive! She wasn't jealous of JOnbenet or anything like that. Patsey was a calm, beautiful woman, who had no reason to kill her sweet little girl.
Thank you! That's what I've always thought, although I have no particular reason to think so. IMO blaming Patsy or John is grasping at straws, not looking for the truth.
