The evidence all points to an intruder.
Why is it so hard to believe that she was killed by an intruder?
To me, the note points to an insider - too much familiarity. It is just my opinion - but I think mother stumbled on a horrible accident - & in her covering it up - a seething resentment of her husband came out in the "ransom note". Don't try to grow a brain....etc
Brother could have just inflicted the head injury & mother could have finished it off with the garote so JonBenet couldn't tell what happened. Very, very sad when you think about it all.
I would implore everyone not to judge the Ramsey's too strongly. They were and are both very strong Christians, unfortunately you won't hear anything about that in the media.
An intruder, a real intruder, would not have written a ransom note on stationery in the house and edited it and then stuff the body in a closet that was almost hidden from view.........
Maybe the fact that there were no footprint in the snow. Did the "intruder" levitate themselves across the yard?
I suppose it's possible, after all Vince Foster's corpse "levitated" itself across a muddy park without getting a speck of mud on the bottom of his shoes.
