The evidence is that JonBenet is DEAD... Patsy's and John's fibers are all over the crime scene, there is no evidence of a home invasion nor an intruder (not in the real world, anyway).
If any third parties were involved, it doesn't negate the physical evidence implicating the Ramseys. The possibility that they had help killing her doesn't make them any less involved.
IMO, that's all anyone needs to bring murder charges against the Ramseys jointly. JB didn't kill herself and the evidence implicates them.
IMO, any RST fantasies would easily be chewed up and spit out by a competent prosecutor in a trial.
I, too, think Dr. Wecht's information is excellent.
Fulton - excellent question! And why didn't they sue Dr. Andrew Hodges either? Interesting that both those theorists name John as the molester.
Apparently the Ramseys don't want to go down that path. Why not?
