Possibly because there was limited cell service in the area of the house she was staying at? I have mentioned before that we have that problem where I live.
I am just going off of your hypothetical scenario that she made it back because you asked what she does next, implying she had control of the situation.
I don't know that she did make it back inside the house.
I imagine she was picked up as she neared the house, or somewhere along her jog route, taken onto 80 and down to the area of the pig farms, harmed and possibly left there somewhere, and that the perpetrator(s) then took her to the area on the top northeast highlighted spot on LE's map where that person, or one of the people, may live.
