COEUR D'ALENE, Idaho -- A man who spent at least 30 minutes clinging to a capsized boat in a cold lake in northern Idaho has died of hypothermia.
The Kootenai County sheriff's office says 52-year-old Dwayne Knapton of Osburn died Wednesday at a Coeur d'Alene hospital.
Knapton and 51-year-old Michael Jensen of Pinehurst were duck hunting on Medicine Lake near Medimont when their 10-foot boat was swamped and capsized. The men were not wearing life jackets and held onto the boat for 30 to 45 minutes.
A traveler on Highway 3 noticed the men early Wednesday afternoon, called 911 and flagged down an Idaho Fish and Game officer. Two Fish and Game officers launched an airboat and retrieved the men.
Knapton was taken by air ambulance to Kootenai Medical Center. Jensen was treated at the scene.
