A 58-year-old Waunakee man has collapsed and died while deer hunting in Iowa County.

The Iowa County sheriff's office says Fred Laufenberg was pronounced dead at the scene in a field in the Town of Brigham.

The Capital Times reports Laufenberg had walked with his son about three-quarters of a mile off the roadway into a field when he collapsed Monday.

Authorities believe he died of cardiac arrest. An autopsy was scheduled Tuesday.
