Repercussions for Maura having left the accident site are discussed here: https://www.reddit.com/r/MauraMurrayEvidence/comments/5fk8q2/if_maura_murray_was_alone_and_not_dui_she_had/
I don't propose that Maura would have walked off into the woods immediately like a Zombie from the Walking dead. Instead, I believe she ended up in a very dangerous area of the forest, just off 112. An area too dangerous even for law enforcement searchers, and, as a result, she has not been found yet. I explain how I think this could have happened below.
Assuming that Maura had successfully evaded law enforcement and was at a distance from the accident site, her next immediate concern would be to obtain housing for the night. The basic human need for shelter and food must have been a priority at that time.
If we assume, when Maura fled the accident site, that she believed she could make it to the next town to obtain housing, the following scenario is possible:
This sign post indicates that another town was further down 112, which one might assume, has lodging available to it:
If Maura went down 112 and got quite far out, she would eventually be traveling up Kancamagus Pass. This part of 112 features a "gradual incline during the initial 16 miles" with an additional "5 miles" with "an average 7% grade" with a "1,300 feet rise over 4.6 miles."
"During the initial 16 miles you’ll only be transitioning about 1,000 feet vertically so you know that you’ll be facing quite a feat closer to the end. You’ll want to pace yourself accordingly so that you’ll have the energy necessary when you reach the steeper climb after already having traveled a number of kilometers. This can be quite a trick and many cyclists falter at the end because they burned up too much steam at the beginning.
Once you’ve pushed your bike approximately 15 miles you’ll level out..."
It is very possible Maura got very far down 112 and found herself unable to continue or go back. If Maura had hit "the wall" and was exhausted, Maura would suddenly find herself in a situation in which she had no good choices.
The best choice for her would be to attempt to build some shelter off the side of the road.
If we take the bookmark as a clue, Maura had just read Chapter 15 of the Not Without Peril book, here: Chapter15.pdf In that chapter, there is a discussion about building shelters.
The Oxygen show does address this issue, when they discuss the search made by New Hampshire Fish and Game Lt. Todd Bogardus here: http://www.oxygen.com/video/share/3600196.
However, I have to wonder if there were places that were too dangerous for Lt. Bogardus to take his dogs, even during a search. And a steep incline area strikes me as a good possibility.
Its very dark out there. According to Fred Murray, "you can't see your hand in front of your face" https://www.youtube.com/watch?v=bTtuowTdeaM&feature=youtu.be&t=3m7s.
I think it is reasonable to consider the possibility that Maura exited the road to build shelter while there was inadequate lighting. I don't know the area or terrain up there at all - I've never been there, but I do think its possible that the area off the road could have been dangerous enough, that, a misstep could have resulted in a life ending fall.
The question is, where would that be?
Here is a section of Google Maps that appears to be the start of such an incline towards Mt Moosilauke, the cause of the steep incline:
In my opinion, this area should be searched, (BUT SAFELY) in addition to dangerous areas off of Old Peters Road.
