Kirsten Heisig (August 24, 1961, Krefeld – June/July 2010, Berlin) was a German juvenile magistrate. Heisig was criticized by some ethnic minorities for her tactics and for her view that some foreign cultures neglect education and encourage juvenile delinquency. As a juvenile magistrate for an area with a crime rate 40% above the average of Berlin, she initiated a model (Neuköllner Modell) that streamlined procedures and targeted an appearance before court within 3-5 weeks after the deed had been committed for deeds punishable by a maximum imprisonment of 4 weeks. Other key elements were encounters between delinquent and victim and community service. This model was extended to the entire city of Berlin in June 2010 and caught attention on a national level.
She was found dead in the forest near Heiligensee at the 3rd of July, 2010; after a search action of five days. The alleged suicide happened shortly after her submission of the manuscript of her book: Das Ende der Geduld: Konsequent gegen jugendliche Gewalttäter. (trans. When Patience Comes to an End: Zero Tolerance for Juvenile Delinquents). Blurb from the dust jacket: "Wenn wir nicht rasch und konsequent handeln, wenn wir unsere Rechts- und Werteordnung nicht entschlossen durchsetzen, werden wir den Kampf gegen die Jugendgewalt verlieren." (trans. "If we do not react swiftly and decisively, if we do not preserve our legal structures and values, we will lose our struggle against juvenile violence.")
