In June 1945, after the United States took over Austria, an American soldier found the "Hartheim statistics" in the Castle. This was a 39-page report written about the T-4 Euthanasia Programme ("Aktion T4"). It was meant to be seen by other Nazis in the program only. In the report were monthly counts of how many people with mental and physical disabilities were "disinfected" (gassed to death) in the Nazis' six euthanasia centres. In 1968 and 1970, an ex-employee said that he had to put together the material at the end of 1942. The Hartheim statistics included a page that said that "disinfecting [killing] 70,273 people with a life expectation of 10 years" had saved food in the value of 141,775,573.80 Reichsmarks.
