They were killing the last witnesses to earlier atrocities.
“Margit held a large party in the town of Rechnitz on the Austrian-Hungarian border to fete her Nazi friends. She, the daughter and heiress of European baron and tycoon Heinrich Thyssen.”
The Theissen family continues to thrive. Its spawn have purchased landholdings from as far away as Arizona and Paraguay. In fact, the family never paid the price that was owed for its involvement in WWII.
Possible but then one would wonder about the non Jewish
witnesses to these final mass murders. Pretty weird to
throw a party in order to facilitate such an atrocity,
especially when your side is facing imminent defeat.
