Authorities were called out at 8:30 am Wednesday to Olive and Winery avenues, across from Ewing Elementary School.
A witness said there appeared to be a dead body hanging on the fence.
Police believe the man tried to climb the fence and got pierced in the calf by a metal bar.
The man has not been identified, but police say he was 68 years old.
There do not appear to be any other factors in the man's death.
