One other thought and I'm going to break my own rule of staying very pragmatic about the possible scenario. I always say that in the absence of data we tend to get a bit far fetched in our theories, and this may be the case with the following notion.
Aside from the obvious trauma that was the result of being hit by the cars, do we know if this Doe had any evidence of prior abuse (fading bruises, etc.), or if there was evidence to suggest sexual assault or even recent sexual activity? Here's where I'm going with this. It's those expensive porcelain crowns. They just throw a normal scenario way off. Without those, we could just chalk this up to some goth gypsy who was wacked out on drugs and met a sad end. But those crowns....was she the mistress of some wealthy man in Huntington Beach (lots of wealth there) who dismissed her? Did this propel her to this sad and desperate act? I originally thought that she was jilted. It was one of the first impressions I had. Far fetched, but something about this adds up. Was there a sample of the dental material kept I wonder? Something tells me that work was done right there in Huntington Beach, and someone has been keeping quiet about it all these years. Perhaps she had an older rich illicit lover who had an appreciation for a busty young woman? Again, a far reaching theory, but something about this notion rings true for me.
