I am a woman that uses Head N Shoulders. I also, at times, may switch back and forth with 'good' shampoo so I might have 2 types in my travel bag. But there were 3 on the list, right? And I noticed a travel toothbrush and also a regular toothbrush, which I find odd. I'd only bring 1. Unless 1 was in the car before, left in there in case she sleeps over somewhere (then maybe 1 of the shampoos as well). And since she brought birth control, I'd say that leads away from being suicidal and possibly also rules out the pregnancy theory. Yeah, I am in the camp of her running away from DUI accident and getting lost in the cold woods and dying there (or accepting a ride from a bad guy).
Why no mention of the alcohol? It says list of items found in car (not trunk).
Hmm, interesting you bring that up, as I believe it is an important dimension to theories about the event. IIRC, the alcohol - with the exception of the boxed wine, which would have been too difficult to transport - was missing. So, to tally it up - Present in the Saturn: Franzia, coke bottle with wine in it. Absent from the Saturn: Kahlua, Bailey's, vodka. The police said she had a black backpack (presumably they saw it in the ATM or Liquor Store footage), which also was not present.
So the theory centers around why she took as much booze as she could, while leaving other necessities like her toothbrushes, given her "conscientiousness with oral hygiene" (per her mother). The birth control is also problematic for similar reasons, because it actually undermines the second occupant theory. The rationale for the BC is that there was someone to use it with - a measured choice at the start of the trip. But if she also had a measured reaction to the accident or someone to help calm her, so as to hitch a ride and continue on, one would think those items would have made it into the pack too. If the circumstances were pure panic fueled by the Corolla accident and BAC, or something else, the booze would go. Maybe it was something as simple as: run down the 112 in the dark to hide the booze, and then she got lost and sat down for a minute.
One of my pet theories: pure speculation...is that she was on a segment of the 112 she didn't know. It actually helps explain why she didn't take the 302 from the 91 and also suggests how disoriented she would have been.
