From an article by Markus Bleistein:
What should have found the Austrian federal president guilty in war crime complicity, bursted like a bubble in a small room of the Landeskriminalamt Stuttgart (LKA). 50.000 Deutsche Mark was the price for an incriminatory telegram signed by Waldheim that the “Spiegel” had paid for. The forensic scientist Bernhard Haas exposed the document within a short time as a forgery. The Czech typewriter manufacturer that had produced the typewriter that was being used to type this document had started production first in the year 1949.
