Metro Police say a man drowned overnight at Elm Hill Marina.
Mark Sherrill, 56, was last seen alive Friday night.
A friend found his body this morning.
Police say the Smyrna resident had a houseboat on the marina. He reportedly left his boat late last night to go hear live music.
According to police, Sherrill apparently fell down a steep embankment, approximately 20 feet into the water and died.
Investigators do not believe foul play was involved.
The Medical Examiner will determine the exact cause of death.
