I am intrigued that you think you know more than you do. For all we know, the girl ran away and LIKES to crawl around in dumpsters naked. There are some very strange kids out there. They grow up to be strange adults. We have no idea if this girl is a victim or if she is just a nut or just plain ignorant. If she is a victim, we don’t know if her parents are the ones who did it.
I am still intrigued you do not seem to be bothered by this story.
