Who is Walther

[VIPER999]

I am doing a research. During my research the name Walther (or Vater) is constantly repeating. I want to ask you if you can help me identify this mysterious Walther person. My indications say that he was a news reporter (working maybe for the Die Donau and with high influence in the Signal editorial politic), it's possible that before the war he was working as an attache for press in he Embassy of Germany in Belgrade. It looks like he had very big influence in the Gestapo, beacause it is known that he liberated some Serbs/Croats from the concentration camp Banjica, and that he made possible for some to travel free to Germany - because he arranged for them to get German passports (Passiershein), so it is in my belief that he was also a high ranked SS officer. Its also spoken that he allegedly emigrated to Venezuela.
With greetings
