A Wild Man
It was a disheveled man wearing just a loincloth, running among the bushes, growling and hollering in a beast-like manner. He seemed like he was trying to avoid them.
As the family reported, the thing that impacted them the most was the smell that the man seemed to emit. They described it as being horridly fetid and remindful of spoiled meat. Could that be one of the authors of Martin’s disappearance?
