Ames,
Please review the Forensic Evidence thread, I have covered it exhaustively there.
Summarising, JonBenet was left wearing urine-soaked underwear and longjohns, despite the crime-scene being staged and JonBenet being redressed, her urine-soaked clothing was ignored, and we know that her killer(s) were aware of this due to the staging undertaken outside the wine-cellar door! Also JonBenet's feces soiled jeans/pants were left in plain view upon the bathroom floor.
So if a toileting issue was the originating factor in JonBenet's death and the crime-scene was staged to obscure this, then the above forensic evidence contradicts this!
Which leads to the obvious conclusion that some other factor(s) lies behind the death of JonBenet.
