Photo Gallery: Investigators Dig for Clues in Zwickau
Police dig for clues in the rubble of an exploded house in Zwickau on Nov. 9. New evidence has come to light suggesting a right-wing extremist motivation behind the murder of a policewoman in Heilbronn in eastern Germany in 2007 and the execution-style killings of eight Turks and one Greek from 2000 to 2006 -- a spree which came to be known as the "Doner Killings."
