Actually, Concerned Mama, the way that MH was "laid to rest" in a peaceful place by the water suggests that the person who put her there had some kind of conscience. This also fits with what the VA State Police have said about a suspect that had a deep sense of shame. Those two things would seem to fit well with what we know about JM's background.I just can't see it, to be honest. Reading the description of the rape in Fairfax makes him look like a lone rapist with some serious violent tendencies for his own gratification. Also, the "wealth of evidence" left behind in the MH case makes it look like he's not the sharpest tool in the shed. LE just needed a forensic match for their suspect, and JLM apparently got sloppy and bold enough to give them what they needed. What a horrible tragedy that it meant losing another bright, beautiful young girl with such a promising future.
None of this to say that JM is a good guy, and hasn't committed some very evil acts. I am just not sure he did it by himself.
