A Tennessee Wildlife Resource Agency officer made an alarming discovery on a bluff above Percy Priest Lake Sunday.
He found a bag containing bones and a pair of tennis shoes.
TWRA wildlife officer Scott Bauer confirmed to News 2 Monday that the bones are human.
The bag was found deep in the woods near Lincoya Bay Apartments, at the popular bluffs over Percy Priest Lake.
It was close to a popular point where people jump or take a rope swing into the water.
Metro police have taken over the investigation.
