Ray's case, however, is somewhat different. He is not claiming that he was raised in the wild, merely that he'd been living in the forest with his family for years. There are, in fact, hundreds of thousands of people throughout Europe living rural, quasi-nomadic lifestyles (including the much-maligned Romany, or Gypsies). So the idea that a father and son could live in a tent in the woods (possibly for years) is quite plausible.
However authorities grew more suspicious of Ray's story as weeks passed and no new leads turned up to support his story. For example Ray was unable to lead investigators to the forest where he claimed to have lived for five years, despite (apparently) having walked to Berlin from those woods just weeks earlier. His clothing, possessions, and tent were in unusually good condition for having been in continuous use for years. Furthermore, German police records revealed no car crash deaths of a woman named Doreen in the previous ten years. Ray also was reluctant to publicize his photograph, and refused to help police find members of his extended family, claiming that it would be pointless because they had all died. All this cast considerable doubt on the "forest boy's" story.
