Authorities said an 18-year-old man has died while swimming at the Clinch Park Marina in Traverse City.
The Traverse City Record-Eagle reported that Michael Knudsen of Mancelona may have received an electrical shock in the water while swimming Monday with a friend. He went under the water about 7:30 p.m. and didn't resurface. The friend reported getting a shock.
Rescuers arrived, and marina employees cut power to the dock. Two firefighters jumped into the water and found Knudsen unresponsive under the dock.
