The Fond du Lac County Sheriff’s Office is investigating the death of a 19-year-old man who fell while hiking at Oakfield Ledge State Nature Area. The victim has been identified as Pierce Neighbor of Fond du Lac. Neighbor was hiking with a group of friends along the Niagara Escarpment Friday when the accident happened. When his companions called for help, they couldn’t provide an exact location, so emergency responders used the G-P-S signal on the cell phone to locate them. The victim landed on some rocks and was pronounced dead at the scene.
