The only thing Lin Wood has to connect Karr to JonBenet in *any* way is to keep saying over and over that Karr at one time lived in Conyers, GA - which has absolutely nothing to do with anything at all, except Lin gets to be on the TeeVee and charge John Ramsey some more dough.
Wood also seemed to intimate that Karr had been sending cryptic letters to Patsy but that doesn't prove guilt or innocense to me. I'll bet the Ramseys got a ton of mail from cranks all over the world.
