Hans Kozak is a former officer in the World War II-era Nazi death camps, allegedly participating in the Holocaust, with numerous witnesses to his misdeeds. Kozak seemed to live in a continual nightmare, hearing pounding noises, screaming, carrying a knife, etc. Per Dr. Leo Krebbs, one of those witnesses, Kozak killed two children in front of their parents who dared to ask what their fate would be after Kozak killed the parents, then killed the mother. Krebbs' foundation was working to have Kozak deported and put on trial for war crimes, but Kozak's daughter, Helen Jackson, killed every witness to her father's misdeeds except Krebbs, but was thwarted by the police, and Krebbs was found in Coral Gables, his fate unknown.
