A sinking vehicle has been pulled from a pond in Sherman.  The Volunteer Fire Department was called to Schimpf Pon at Volunteer Park on Sunday afternoon.  It was unknown if the half-submerged minivan was occupied.  Firefighters donned dry suits and entered the water to search for potential victims.  No occupants were found in the vehicle.  The driver was later located and evaluated before being transported to New Milford Hospital.  Gaylordsville Volunteer Fire responded with mutual aid.  Crews cleared the scene about 2 and a half hours later.
