A body has been pulled from Candlewood Lake and is believed to be that of the man who went missing Friday night near Chicken Rock. The Sherman Volunteer Fire Department says the search ended just before 10 o'clock yesterday morning when they successfully recovered a male matching the description of the missing swimmer.  After being spotted by Candlewood Lake Authority Marine Patrol, just southeast of Green Island, Marine 7 responded.  Positive identification of the missing swimmer remains to be completed.   The incident remains under investigation by the state Department of Energy and Environmental Protection.
