Proksch fled to the Philippines in 1988 after Hans Pretterebner published a book about the scandal. Returning to Vienna incognito in 1989, he was recognized and arrested. He was sentenced to 20 years in prison on March 11, 1991. Walking out of the courtroom Proksch said "Heil Hitler!". A year later the sentence was increased to life in prison. He died on 27 June 2001 during heart surgery.
