I'm with Sutton on this one, Unless there are 100% confirmed accurate dump site coordinates and they then intersect directly through the Continental hotel then I just don't buy the theory of the CSK plotting maps to find dump sites and using cryptic clues e.t.c I think he had a body in the boot and drove half a tank of gas or so till he felt safe enough to dump it in a secluded area, the next body he chose the other direction and like someone suggested, coincidentally the highway runs north to south. IMO beyond that I doubt there is too much more reading into the locations.
I also doubt SS was his first, by the time he started this "csk" spree he was already a well organised killer, a noobie killer makes mistakes this guy was almost perfect in the abduction, murder and dumping of his victim.... Only a guestimated abduction point, no kill point, dump sites found well after the elements destroyed any significant remaining forensic evidence and lastly no witnesses.
I also doubt the CSK was the one that rang Don Spiers and though possible he may read these threads about himself I'd also doubt he has ever posted or played gamed with us, these are the acts of attention






the CSK
does not want unneeded attention.
