It would be like looking for a needle in a haystack if she wandered off the road in a lot of places. Thick woods with dense underbrush, creeks with steep banks, boulders. There are several fire roads and hiking trails off 112, and if Maura hit her head and/or had indeed been drinking, that she took a "shortcut." Is it possible that she carried one or more bottles of liquor with her as she ran/walked, to "keep warm?" If she was drinking actively she would have gotten hypothermic faster and also possibly have gotten disoriented Also, since one potential witness said she ran when she saw him, I believe it's totally possible that Maura tried to travel off the road to avoid detection, wandered too far, and gotten lost. It would not take long to succumb to the elements in those woods on a cold night, and there are bear and mountain lion as well. This has always been, to me, the most likely scenario. She somehow got off the road, got disoriented and lost (or fell and was too injured to make it back to the road), and died of exposure.
