Twin brothers are suspected of stealing millions in jewelry and watches from KaDeWe in Berlin. DNA from the crime scene matches the brothers' DNA. But their DNA is too similar to match either brother individually so the police have to let them go.
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.
How long before this shows up on CSI?
