The Jacksonville Sheriff's office is investigating an underwater mystery near a boat ramp on Jacksonville's north side.
The JSO Dive Team was called out to the T.K. Stokes boat ramp on Riverview Road Saturday evening.
Police, the Dive Team and a tow truck were on the scene by the Trout River.
The top of what appears to be a vehicle with the sunroof open was visible from the shore.
No word at this time what police were searching for.
