There are a whole host of problems with social media and the Internet age, but this is one of those times when it really and truly works for the better good:
A scuba-diving YouTuber, who has made it his mission to find missing people, discovered the vehicle of two teens who disappeared 21 years ago in rural Tennessee.
Police in White County on December 1 confirmed his discovery of a car that matched the one driven by Erin Foster, 18, and Jeremy Bechtel, 17, who were reported missing in April 2000.
Jeremy Beau Sides whose YouTube channel is called Exploring with the Nug, told CNN he stumbled upon the cold case while looking through a missing persons database.
