A woman found not breathing at 12:24 p.m. Sunday at Marion Reservoir near a campsite was pronounced dead at St. Luke Hospital after being transported there by Marion ambulance.

At deadline Tuesday, the coroner, sheriff’s department, and emergency crews still were refusing to release the woman’s name, but did say she was not from Marion County.

“It’s my understanding that she walked toward a restroom by the lake,” emergency medical director Travis Parmley said. “That’s where she was found.”

Nearby campers and a sheriff’s deputy already were performing cardiopulmonary resuscitation when ambulance crews arrived about nine minutes after they were dispatched.
