Construction workers accidentally made a chilling discovery that helped solve a 57 year old mystery. Today, we take a look at what these construction workers discovered.

Six hundred and seven people are estimated to go missing in the world every year. Six hundred and seven people, gone without a trace. How many assume new identities? How many are buried, undisturbed for decades until new construction uncovers old remains? The longer a person is missing, the more the chances of closing their case dwindles.

Thank you for watching!
