Does anyone know where Karl-Heinz Kepler?

[Walrus]

I am trying to locate Karl-Heinz Kepler. He was a Hitler Youth in Berlin at the end of the war, and may have served briefly in Hitler's bunker. His father and sister ran the guesthouse for foreign dignatories at Gatow. He lived in Nuremberg after the war. I'd be most grateful if someone put me in touch with him.
