Hope something turns up on this one. So far, not believing this story. Could be wrong, yet everything is too convenient especially since this allegedly took place at age twelve where he and dad entered the woods to live. One can remember age twelve unless there is brain damage. Age seventeen (five years) and cannot remember clues regarding his life at age twelve? This is far from normal (imho).
Let's assume the story according to what the son says is true.. -- Why would a father take his 12 yr old son to the woods (forest) to live & wander around for 5 yrs? - Says a whole lot about his father.... or at least *the son's perception* of the father. Then again, they could both be certifiable.. - too many cases like this one, but never make headlines. Also, sometimes truth is stranger than fiction.
