Edited because I posted the wrong dates at first!
I wonder if there was something wrong with the car.
It's very strange that she would turn her phone off after talking to her mom all that time while she was lost. She would know she was worried about her. I wonder if the battery died because she didn't have a charger.
That's another reason the car may have been running, though, if she was trying to charge her phone.
Or she met with foul play and someone else turned it off.
Imo
