I agree with all of you!
Because where I live is rural, I have thought of the "what would I do if I broke down" scenario (even though I have AAA). Scary to stay a sitting duck in a broken down car in the middle of somewhere, but also scary to walk to a gas station. I HAVE thought that if I did have to walk, I would NOT carry my purse. I would take my CC's and such and stick them in my pocket, but I wouldn't want someone driving by to see I had my purse.
The thing I would NOT leave in my car...…...my PHONE!! I would be ON the phone with someone talking so they would know what was happening! Do I find it strange maybe she wanted to walk to the gas station versus waiting (sometimes hours) on AAA? Not really. But do I find it strange she left everything in her car, YES! I can see the purse & keys (but were they hidden or in clear sight??). I would have locked it in my trunk or under my seat, taken my CC, DL, Cash and phone and headed out. Phone tells you where nearest gas station is, it gives you the option to call 911 if someone does try to pull over and talk to you. I don't understand the leaving the phone.
The only thing I can see for no one reporting her for two days is if the daughter was out of school and staying with Grandma during break and mom was supposed to show up for Thanksgiving and didn't. My kids stay all the time with the grandparents and we can easily go a day or two without talking to them (they are a little older and trust grandparents 100%, no need to check in, they will call us if something is up). So I can see the scenario where daughter is staying with grandma during break and no one missed AH until she was supposed to show and didn't.
I'm 50/50 on this one whether it's self harm, or someone did something. Chances of someone offering her a ride and that person being a murderer is slim, but then we just had the other case where the girl was abducted by a stranger at the gas station and killed. The phone in the car is what really leads me to self harm though. She had plenty of time to call someone and let them know what was happening BEFORE walking anywhere. The car had enough gas to drive to a station after the parents picked it up, it didn't truly break down. So why did she stop when she did??? Why didn't she take her phone with her? No signs of blood or a struggle at the car. Sadly I'm thinking she just walked away.
