It also then makes me think that the searching last year only yielded remains that were not buried or buried and then exposed from natural causes: weather, animals etc. There could be many more victims buried in that area.
thats a good point. If they were buried deep enough that fbi heat signature camera probably wouldn't pick it up either.
I'm glad the police are thinking it's one killer. The theory that he has been tweaking his MO sounds more reasonable and gives the police more to work with.
I agree about the pattern, he's going from more work to more lazy. If SG is related it could have been that he just got really cocky.
