I was imprisoned in the Auschwitz camp from May 1942, and thus after the death of the prisoner Dubois, who was said to have died in 1941 and therefore I have no information about the circumstances of his death. More details about this may be given by the former Auschwitz prisoner Józef Węgrzyn, residing in Kraków, who reportedly stayed with the deceased until his last moment. I will give Węgrzyn’s address in addition to this statement.
The report was thereby concluded and signed.
