Preliminary autopsy results confirm suspicions that a Mancelona teen who drowned in Traverse City's Clinch Marina this week did suffer an electric shock while in the water.
Eighteen-year-old Michael Scott Knudsen died by shock and drowning, according to a release today from city officials.
Knudsen was swimming with a friend off "Dock F" Monday. His friend also reported being shocked, but he managed to make it back to the surface. Power has not been restored to the dock, and that section remains closed.
A city investigation of the dock points to an electrical short in the dock's power systems. The short apparently caused electrical current in the water where Knudsen swam. Officials say there were no indications of electrical problems on the dock before this incident, and they don't know why the short didn't cause the circuit breaker to shut off power.
