DNA evidence from a multimillion-euro jewelry heist in Berlin leads to twins with a criminal record, but since the evidence could point to either one, German law says that neither can be convicted:
German law stipulates that each criminal must be individually proven guilty. The problem in the case of the O. brothers is that their twin DNA is so similar that neither can be exclusively linked to the evidence using current methods of DNA analysis. So even though both have criminal records and may have committed the heist together, Hassan and Abbas O. have been set free.
Both brothers have stolidly refused to comment ever since their arrests on February 11. Since no further evidence has become available, police cannot detain them.
