This appears a little muddled at first, or at least it did to me, but it is a happy little story.

It popped up on one of the FB missing flyers - a 16 year old girl was missing from from Sioux City, Iowa.

Amongst all the comments was one that said that the person sounded like their sister who had the same name, same age, same race, but was adopted when very young and they had no contact.

I am unsure how it happened but the missing girl was found safe and returned to her adoptive family. Since then she has also been reunited with her biological family!

The power of social media used to the good!

You can see the comments below the flyer - just to confuse things, the biological brother posted from his girlfriend's FB account and then his own!
