"She had hanged herself at dawn"

There is statistical proof that the risk of suicide in long term prisoners awaiting release is higher than average.  Factors that can affect this include the age of the prisoner (it is more common in older people) and if the inmate has been held in a local prison.  A significant number of prominent Nazis committed suicide at the end of the war, but this was not motivated so much by guilt as a wish to end their lives alongside the end of the Third Reich, and escape trial.  Many German civilians also took their own lives through a sense of despair, fear or grief at their country's defeat.
