CADOTT,WI -- An autopsy of a Marquette woman who died at Rock Fest in Cadott, Wisconsin has not revealed a cause of death.
On Friday, Chippewa County, Wisconsin Sheriff Jim Kowalczyk said that further testing is needed to determine how Joann Helene Caldwell, 38, of Marquette, died.
Caldwell was found unconscious on Thursday morning on the festival grounds outside Cadott.
Sheriff Kowalczyk says toxicology tests could take time to finish and that he likely will not receive a ruling on a cause of death anytime soon.
