Why did Rudolf hoss go to prison?

because According to several estimates the Nazi Commandant of Auschwitz Rudolf Hoess was responsible for exterminating millions of people.By mid 1942, Rudolf Hoess started mass gassing of Jews using Zyklon-B at Auschwitz, where extermination was conducted on an industrial scale with some estimates running as high as 2,5 million persons eventually killed through gassing, starvation, disease, shooting, and burning

I think that the question refers to Hoess' stint in prison in 1924. It was for a rather brutal murder of a former teacher who was suspected of starting a communist group.
