She was given three separate tests. One on her role, if any, in the actual murder, one on her knowledge of who killed JonBenet and a third on the note. John Ramsey was questioned on his role in the murder if any and his knowledge of who did it.
That doesn't surprise me of course. I stopped watching Greta cause she was pissin me off with regard to the Holloway case on Aruba. I agree , that it was a terrible shame about Patsy. RIP.
