Emerson County has reports of strange shadowy creatures/people first in 1957. In August of 1997, roughly 2 miles from where original reports originated, a video camera was found and turned into local authorities. What they saw on the old tape was scary, mysterious, and remains unexplained to this day. Some people refer to this “shadowy creature” as a “Shadow Person”.

very interesting…
This looks very much like a Tulpa,I would be very interested to learn of the history of the area.
I believe it may have been there along time.
That could very well be reptoid. They have the ability to “cloak” and even shape-shift.
I also would like to add that the hissing like shriek is a giveaway. Very interesting indeed!
