Heart attacks apparently claimed the lives of two men hunting in two different locations in the county Saturday, the opening day of shotgun deer season.

The Winneshiek County Sheriff's Department, Iowa Department of Natural Resources, Iowa State Patrol, Decorah Paramedic Services, Winneshiek First Responders and the Decorah Fire Department's search and rescue unit arrived at the first incident in the Bluffton area Saturday.

A 61-year-old male subject was reportedly hunting with friends and was found unconscious in a wooded area. CPR was performed and he was transported to the Winneshiek Medical Center. It was later determined he suffered a heart attack while hunting with friends, and was unable to be resuscitated.

The second incident occurred in the Highlandville area. A 54-year-old man was hunting with a friend and was found unconscious in a wooded area. CPR was performed, and it was determined he suffered a heart attack while hunting with his friend, and was unable to resuscitated.

The Winneshiek County Sheriff's Department said Monday the names of the deceased are being withheld until later in the week to allow all family members to be notified.

A thorough investigation was completed and it was determined in both cases death was caused by health issues, and did not involve a discharge of a weapon or accidental shooting.
