There are more than 600 children whose identity remains a mystery. Some of the cases date all the way back to the 1950s.
Jane Gainesville Doe was only a few months old when her little body was found floating in a pond in Alachua County off Route North of Gainesville in 2003. More than a decade later and no one, not even her mother or father, has stepped forward to identify her.
"This little girl here, blond hair, blue eyes. How can she not have her name?" said Angela Williamson with the National Center for Missing and Exploited Children.
Artists at the National Center for Missing and Exploited Children help rebuild the faces of children whose bodies are just skeletons. Now the hope is that social media will help these children be identified.
"Here's our Facebook page, we call it Help ID me," said Williamson.
You can search by state to see if you recognize them. In Florida, there are 19 pictures of children who need to be identified, and a dozen whose bodies were found in Georgia.
"Did you live next door to them and one day, you never saw them again?," said Williamson.
In only a few weeks the Help ID Me Facebook page has generated 20 new leads, and more than 13,000 likes.
