The footage was shot at a cemetery in a province of Argentina called Córdoba.
The Argentinean news crew while reporting on a different matter, manged to capture what appears to be a person walking on the roof of the cemetery.
According to personal and groundskeepers, there was no one at that time on the roof doing repairs or any other checks. The roof is not accessible to regular visitors.
Interesting video, but not enough evidence to call it a “ghost” or to deem it supernatural. However, notice how it moves very unnatural. Almost like it glides.(above taken from the Ghost Theory )
