The prisoner functionaries at Flossenbürg were unusually brutal and corrupt, because the positions had been taken by criminal prisoners even though overall only about 5% of prisoners had been classified as criminal. The final camp elder, Anton Uhl, was beaten to death by prisoners after liberation. Many of the criminal functionaries sexually abused young male prisoners, causing the commandant to isolate teenage boys in a separate barracks. The SS hierarchy was also known for corruption and brutality. Prisoners were mistreated in various ways, from being beaten or doused with cold water to being shot by guards during alleged escape attempts.
