A 20-year-old woman has died on the campgrounds of a popular music festival in Delaware that has drawn tens of thousands of people.
WDEL-FM reports that police have identified the dead concertgoer as Caroline Friedman of Philadelphia. She was found unresponsive early Sunday in a camping area at Dover International Speedway.
Friedman was pronounced dead at a local hospital a short while later. The station reports that the cause of the young woman's death was not immediately known but authorities don't suspect foul play.
