From everything I've heard the boyfriend has been cleared, she'd already left his home and was alone when she ran out of gas, it's been reported that he was very active in the search and is taking things very hard. When she called her mother her mother offered to come get her and she told her not to because of needing to take her brothers to sunday school later.
I wish I knew why she didn't stop and get gas, she still had quite a distance.
Years ago when I worked evening shift I ran out of gas on my way home from work, about 11:30 at night on a dark and desolate highway. I did not know I was out of gas! The needle had gotten stuck and it still showed I had some in the tank! I had no cell phone and was about 20 miles from home. A man stopped and offered to take me to the town I lived in and I got in the car. Now I would not do that but my thinking at the time was that if he was going to do anything, just being out there alone in the dark and isolated as I was, he could do it right there. I was very lucky, he dropped me off at my doorstep.
A few years ago I had my car breakdown on the interstate during the day time, again no cell phone (I do have 1 now) a man pulled over and offered to give me a lift. I told him no, I'd stay there with the car but could he call my auto club for me. He was dressed like he was in some type of law enforcement! He told me he couldn't make any calls because he didn't have a phone, which I thought was very odd. He was also a bit to insistent that I just get in the car! My hinky meter was up! Right then a highway patrol car did pull over! Talk about good timing. This man drove off as soon as he saw the highway patrol coming.
