wherever she is has to be some place out of the way. if nh is the perp he wouldn't have had time to do something elaborate so she'd likely not be well concealed. if she were in the woods somewhere i'd think, given the time of the year with no leaves on the trees, that someone would have stumbled across something. to me, there's a decent likelihood that she's somewhere the perp has access to that others wouldn't - one of those cases where a body is found buried under a garage years later or in a back yard or something like that. imo for this case to not go cold some neighbor or passerby has to report something odd. there's a missing woman so there's something odd somewhere, someone just has to notice it.
