Has a missing child ever been found as a result of Facebook shares?

Just to be clear, I have no issues with people doing this, it's not a criticism. If my child was missing I'd do anything to get them back. Im just wondering if any have ever been successful? Three or four local children have gone missing recently, there seems to be a new one to share every week :(

I was hearing from a reliable person that teenagers have been going missing recently for fb shares they are found safe and well so people share the safe and well I was horrified it. Is a slow rising trend for a laugh. I know that isn't what you meant but not everything is always as it seems.
