Investigators believe a man working on a billboard accidentally fell to his death Friday afternoon.

The man, identified by co-workers as Keith Fenton, fell while working in the 700 block of Pollard Boulevard, across the street from Turner Field, Sgt. Greg Lyon told The Atlanta Journal-Constitution.

“It appears to be just a tragic accident,” Lyon said.

Fenton, who owned a billboard company, slipped while working and fell to the ground, witnesses said. The Fulton County Medical Examiner’s Office is investigating.

Co-workers said Fenton was a father and recently celebrated his one-year wedding anniversary, Channel 2 Action News reported.
