I think we have discussed GR's fortunate meeting in the sauna with an LE officer he knew, but I believe that was a passing acquaintance, rather than a friend?
To be honest, I cannot imagine LE allowing any possible friendship to affect their professional judgement in such a serious case. Even if one person wanted to close their eyes to the possibilities, what about the rest of the department? To have the full co-operation of an entire department in sweeping a case under the carpet would be a very dangerous path indeed.
I tend to think if there is any conspiracy, it's simply one of silence. Lack of information or updates. That can be very damaging to a case in itself, but I'm still hoping the silence in this case has a greater purpose. If it's worrying us, just imagine the effect it's having on the person who did this to Jennifer.
