I've been watching this segment on the forbidden site, and it was in Spanish. I'm trying to find out more about the segment, and if it was solved.

It was about a girl who I believe is named Sandy Breen, and that she ran off with her boyfriend, Bruce Clark, in the 1950s or 40s or 60s. They're both heirs to a fortune, and Sandy's aunt and friend are now searching for them.

If anyone knows about this case, please leave a comment.
