The Kootenai County sheriff's office says two hypothermic duck hunters were rescued after a passing driver saw them clinging to their capsized boat in Medicine Lake.
Sheriff Rocky Watson says the passer-by called 911 on Wednesday and also flagged down an Idaho Fish and Game officer. Two Game Department officers launched their airboat into the lake and picked up the men.
Watson says one of the men shifted his weight in the boat after they retrieved a duck. That caused the 10-foot boat to list to one side and fill with water.
The sheriff says 52-year-old Dwayne Knapton of Osburn, Idaho, was flown to a Coeur d'Alene hospital where he was initially listed in critical condition. The sheriff's office reported Thursday that despite attempts by medical personnel to revive him, he succumbed to his hypothermic injuries.
The second man, 51-year-old Michael Jensen of Pinehurst, was treated at the scene and released.
The men had been in the 40-degree water for 30 to 45 minutes before they were rescued.
The sheriff says they had life jackets on board but were not wearing them.
