Well, they did look at that and the notion that he'd go a lot further just because it's a fairly open area did seem relatively plausible.
In other news, it appears that one of the cops on Adnan's case is being sued for planting evidence:http://www.courthousenews.com/2013/03/05/55427.htm
This has been alleged elsewhere (the subreddit primarily) but this does to me open up a whole new angle on the case. Perhaps the cops showed Jay where the car was rather than the other way around. Given their behavior elsewhere in the case regarding his string of confessions (specifically, the way they sat with him unrecorded for several hours before they began to record said confessions), I already though it likely-to-plausible that they simply handed Jay the list of cell phone calls and allowed him to cook up a story as to what was going on during said calls. This, frankly, isn't even something that would cause a guy who has a record of planting drugs in a witness' car to "encourage" them to testify off-guard: in this scenario I could definitely see where the cop might think "we've got the guy, now let's make everything else we have add up so we can bring a good case to the prosecution".
The thing of it is, I like SK still have doubts as to whether or not Adnan did it. I don't think that the prosecution even came close to making their case, and it it weren't for the railroady bullshit I think it's entirely plausible that the detectives would have worked harder and found other evidence which really did lead a path to Adnan's or somebody else's door. In a really large sense, I feel like this is the real tragedy here: even if the cops happened to luck into catching the right guy, justice was never served in this case.
