Hello laini. Everything matches so well. I looked at the sketch first, and my first thought was, "How could anyone identify anyone with the sketch. It is so blurry." But, I was surprised to see how similar they look. Also, the conditions under which she left indicate she may have not been mentally stable, and the Doe in AZ committed suicide. The dates work, too.
The only thing I don't understand is that her car was found near Prescott, AZ. Her purse, meds, temporary license, and car keys were there. But, there was no money in the car. The Princess Doe was found in CA. I wonder how that would have worked. Unless, someone took her car around the time she committed suicide. In any case I would submit it, because it could be her. Best to you, laini, and please let us know what happens if you submit the info.
