The Chong Kim Abduction Hoax?

So i recently saw this movie "Abduction of Eden" en.wikipedia.org... . Its a sad story about a girl (Chong Kim) that is kidnapped by a guy pretending to be her boyfriend who ends up selling her into sex traffickers. Now it was a pretty good movie but the problem i had with this is that it said it was based on a true story. So you have a girl that was missing for 2 years and latter found, never mind the international sex trafficking ring. Why cannot i find a single thing to back up this woman's story? Nothing, I can't even find anything that says she was ever missing or recovered.
So her name was Chong Kim, can anyone here find anything to back up her claims? As of now she makes a living talking about this. But nobody really wants to call BS and any effort to get proof is usually met with a lot of personal attacks.
