Medical examiner: Hiker suffered heart attack near Medora
MEDORA, N.D. (AP) -- The North Dakota State Medical Examiner says a hiker from Virginia found dead in Theodore Roosevelt National Park in July suffered a massive heart attack.
Park Superintendent Valerie Naylor says 48-year-old Dan Olszewski of Midlothian, Va., was an avid and well-prepared hiker.
Olszewski had come to the park for a day hike and was reported missing when he did not report to work. His body was found in the park's south unit after a three day, multi-agency search.
An autopsy was performed to determine the cause of death.
Olszewski had been in North Dakota working.
