The problem with this is outside of tampering (which if proven would be an extreme scandal), there is no comeback for this. There is no excuse that explains why he was looking up the specific dump site on July 11th. If it was done in January, there might be an argument there, but it was done the day before she disappeared. I could see an argument if they only found, say a visit to a Toll Brothers website. But that's not the case here.
The guy was given the benefit of a doubt by alot of fencers on here, probably a lot more than BC deserves. But you can't with this one. This is one where you can't say 'well maybe he was just goofing off or maybe he was looking up driving directions' They got him zoomed in on piece of the map that was barely populated, a piece of the map that he himself said he never knew about.
If the defense puts an expert on there that makes it really compelling(and it would have to be seriously lock down compelling), then I may change my thoughts on this but until that time, it is what it is. We now know what caused them to arrest him in Oct.
