Authorities have identified the body of a man found dead in an East Tennessee lake.
TBI spokeswoman Kristin Helm told WBIR-TV it was 19-year-old Zachary Tyler Wilson's body found at Kefauver Park in Madisonville on Sunday afternoon.
Helm said there were no obvious signs of trauma to Wilson's body, and a medical examination will determine the cause of his death.
Tennessee forestry officials say someone has been setting fires along the Cumberland Trail.
Four fires erupted Saturday alone, burning more than 200 acres. Fires of suspicious origin last week were in Campbell, Scott and Anderson counties.
Assistant District Forester Nathan Waters told WVLT-TV the burn patterns indicate the fires spread from intentional sources.
