Update: Sheriff ID's Man Who Drowned in Cass Lake On Saturday

WALKER (WJON News) -- A man drowned on a lake in northern Minnesota over the weekend.

The Cass County Sheriff's Office says the incident happened on Saturday, just before 6:00 p.m. on Cass Lake.

Family, friends, and former classmates are mourning the loss of a Grafton, North Dakota, man who drowned on Cass Lake in north central Minnesota on Saturday.

41-year-old Jon Koehmstedt was the athletic director and assistant principal for 7-12 grades at Grafton High School and Junior High.

He jumped off the pontoon to work on a boat motor problem and didn't resurface. Some kids on the boat attempted to throw him a life jacket, and the boat began to drift in the high winds. The boat was later intercepted by other boaters on the lake, and a 911 call was made.

At about 8:00 p.m., the victim's body was recovered. He was not wearing a life jacket.

An autopsy is scheduled with the Ramsey County Medical Examiner's Office.
