Right now, this whole thing sounds suspicious. There are reports of him having lived near the Ramsey's place in Georgia. So let's see, he committed this horrific crime in Colorado and then packed up his bags and followed the Ramsey's to Georgia? If so, why? And how did he know about the $118,000 amount? And why bother writing a 3 page ransom note for that matter?
Also could it be that he learned of additional details in this case via his emails to Patsy Ramsey (assuming she replied to him)?
I have no doubt that this guy has done some terrible things but at this moment i have my doubts that he was the one who killed JonBenet and until further details come out i am leaning towards this being a deranged phony confession by a guy desperately seeking to become famously infamous.
And he just happened to mention facts no one knew about the murder scene.
