Andre Bamberski's 15-year-old daughter Kalinka died in 1982.
Bamberski suspected that Kalinka's stepfather, Dieter Krombach, had given the girl a dangerous injection so he could rape her; the injection apparently caused her death.
A French court convicted Krombach in absentia; a German court, however, deemed that the case had insufficient evidence to prove his guilt, and refused to extradite Krombach.
Deciding to take action of his own, Bamberski hired two henchmen to bring Krombach, 79, from Germany to France for trial in 2009.
The AP reports that Krombach was "tied up and dumped near a French courthouse."
