Bones pulled from a Revolutionary War battlefield in South Carolina have finally been given a name: Pvt. John Pumphrey, a teenage Maryland soldier killed at the Battle of Camden on August 16, 1780.
Why it matters
It's believed to be the oldest unidentified American war casualty ever solved, showing that genetic genealogy techniques built for modern cold cases can reach back nearly 250 years.
What to watch
Researchers say the same lab methods could be used to identify other unmarked Revolutionary War dead recovered from battlefields across the East Coast.
