If BG is so inclined to want to return to this area because it is comfortable or convenient (on his work route for example / awareness space, etc), I think he would (have to) refrain due to the "heat". Which lends itself to the theory that he could be choosing another hunting ground. While many predators have various MOs and sometimes multiple variances of victim preferences (children and adults, black and white for example), I suspect he may go with the "if it ain't broken don't fix it" approach, meaning if he is that skilled at eluding LE he will choose in the future to go along with a formula that has worked: an isolated wooded area. But who really knows. I think his element of self control and restraint may be key here, can he control himself from seizing a potential future opportunity to abduct and kill which could be riskier (say at a shopping mall for example, or kid on the street).
Thinking further about this...dang just lost it, I hate it when that happens.
I lost that thought, but this brings another though that if he is not in a cooling period and needs an easy "fix" he might go with a prostitute who will give him no resistance as far as getting in the car with him.
