Officials say a second person has died after attending the Bonnaroo Music and Arts Festival.

Coffee County Sheriff Stephen M. Graves said Monday 24-year-old Christopher William Yoder died of hyperthermia early Sunday after being airlifted from the festival to Erlanger Hospital in Chattanooga.

Graves said he is awaiting toxicology reports.

Bonnaroo organizers released a statement saying, "The safety of our patrons is our No. 1 concern, and we are deeply saddened by this."

On Thursday, the body of a 32-year-old woman was found inside a tent at the festival. An autopsy is to be performed.

The 10th annual festival, with 80,000 attendees, was Thursday through Sunday at a 700-acre farm.
