At that precise moment this photograph was taken; remember nothing could be seen with the naked eye; and imagine the shock when this entity could be seen connecting itself to the investigator AT THE EXACT SPOT he was pointing to where the stabbing pain originated from?
He was that shocked by the experience, he never attended an investigation again.
What was the supernatural being? What was its intention. Refer back to a previous image on here to see again the appearance of the supernatural being that had undertaken this attack.
Remember, this phenomenon is real. Supernatural beings on other dimensions are real. Mankind knows so little about the reality it co-exists in with unseen beings.
It's likely this supernatural being saw our colleague as a 'drive through KFC' and had chosen to feed from his life force. A dangerous situation.
