RedactedNarrative: While working boating enforcement on Cherokee Lake in Hawkins County, Tennessee on July 12, 2017 at approximately 22:37 I received a call from Officer advising of a boating accident near Quarryville Access Area.  Approximately one quarter of a mile past the access area, I observed a flashing white light along the bank and white light about 75 yards from the bank in the water.  I began going toward the light.  As I got closer, I observed a boat going in circles near the silo.  At approximately 22:46 I traveled to the bank where subject was waiving a flashlight.  I ask him if there was anybody still in the water and he said that he didn’t know.  I pulled my patrol vessel on the bank and jumped off.  I asked where the injured man was and Subject began pointing to the edge of the water.  I ran over to victim, put on gloves and Subject helped me pull him up on the bank.  I began rendering aid by conducting CPR on Victim.  He did not have a pulse at this time.  I continued to do CPR until EMS arrived on scene and took over.  Victim was pronounced dead on scene at 11:50 P.M by the Hawkins County Coroner.
