What makes Maura's case so confounding is that there are a number of things which at least in theory could have happened to her.
I believe that Maura was struggling with a lot of difficult issues at the time of her vanishing. No theories can IMHO be dismissed as impossible without further evidence at hand.
Even so I personally believe that Maura most likely became a victim of foul play in NH.
I just got a private message asking me to clarify the timeline of events on that fateful February 9th 2004.
It is to be found on Maura Murray's Wikipedia page with the relevant timeline for the hours immediately after her disappearance to be located under the heading 'Disappearance".
Does anything strike you as at least somewhat strange when reading through the rather charitably bland but factually correct Wikipedia text?
Ummm the Statie ?
