NASHVILLE — A 29-year-old Indiana woman is dead after being found unresponsive at a campsite at Bonnaroo Music and Arts Festival, officials confirmed Tuesday. 

The woman was identified as Leeann Sizemore, of Lowell, Indiana, according to Manchester Police Department Chief Mark Yother.

Sizemore had known medical issues, but it is unclear what led to her death, Yother said.

She was given CPR after being found unresponsive by a friend early Sunday in the camping area, said Chief Investigator Brandon Tomberlin, who is handling the death investigation.

Sizemore was taken to Unity Medical Center in Manchester where she was pronounced dead, Tomberlin said.

An autopsy is pending, Tomberlin said, and the state medical examiner’s office will determine her cause and manner of death.
