Der letzte Zeuge (The Last Witness) is a German crime television series set in Berlin. Created by Gregor Edelmann, it aired on ZDF from 1998 to 2007 and was mostly directed by Bernhard Stephan. It stars Ulrich Mühe as medical examiner Dr Robert Kolmaar, along with Gesine Cukrowski as his colleague Dr Judith Sommer and Jörg Gudzuhn as commissioner Johannes "Joe" Hoffer. After Mühe's death in 2007, both Gudzuhn and Cukrowski stated they did not want to continue without him, which is why the ZDF would later announce the series' termination.
