Has anyone considered the possibility that jonbenet tried to kill herself that night, that she was so distraught that she stood on a chair and tied a rope around her own neck? I know she was only six, but even young children can be pushed to a certain limit and crack. Could patsy have found her daughter almost dead from strangulation and because that would blow the illusion of a perfect family, further staging might have taken place. Or the rope was so tight, it would not come off and it was clear she was in great distress and dying. Could someone have finished the job as a way to end her suffering? Of course, that doesn't explain the head injury. I dont believe an intruder was involved, but will say, the simplest explanation is often the right one.
