There simply could not have been an intruder.

I know we shouldn’t state things as fact when there’s no 100% proof of much of anything in this case, but from what I’ve seen in my 3 ish weeks of being absolutely consumed by this case, everything suggests that there simply was no intruder. I might be stating the obvious to a lot of people here, but there was absolutely NO trace of any breaking and entering, plus the ransom note (again not 100% proven) being almost a perfect match for Patsy’s handwriting. How would such an intelligent and sophisticated intruder be smart enough to go in and out without a trace, match stroke for stroke Patsy’s handwriting, yet also be so incompetent as to accidentally kill JonBenet in a kidnapping gone wrong?
