Douglas County investigators are still sorting through how an SUV wound up in Flanagan Lake.
The vehicle was recovered Saturday after a passerby noticed it in the water. Investigators believe the driver of the Chevy Trailblazer had been traveling west on Ida Street when the vehicle swerved, went through a guardrail and plunged into the lake.
Rescue crews searched the water, but there was no sign of the driver at the scene.
Deputies are trying to track down the owner of the vehicle.
