The wilderness boy making headlines out of Germany might have walked an amazing 150 miles through the woods before he touched concrete, RadarOnline.com has learned.

The boy, believed to have inhabited the Czechoslovakian side of the Ore mountains, "would have walked all the way to Berlin from the Czech Republic," a source close to the situation said. "This would have been a much harder prospect than simply walking from woods south of Berlin, which is what many believed he had done up until now."

As we previously reported, the boy -- who is believed to be 17 years old and answers to the name “Ray” -- claims he spent five years living in the wilderness before sprouting up at Berlin City Hall in Germany September 5, following what he claims was his father's death.
