I remember watching this movie as a kid and can barely remember anything about it. Except that there was a teen girl who has a best friend as a kid that went missing. Her family travels somewhere and she finally finds out what happened to her. I know she was killed and they find her bones. I also believe her name is Rachel. Or Rebecca.

That's all I remember but would LOVE to know what it is. Any help??

It's possible that you're thinking of 1984's Mystery Mansion (http://www.imdb.com/title/tt0091587/plotsummary).

That's it!! Thank you so so much!!
