Mystery of murdered Russian Tsar's missing children solved by DNA study

DNA analysis of human remains found in central Russia appear to have ended the mystery over the demise of the last Tsar of Russia Nicholas II and his wife and children at the hands of the Bolsheviks in 1918. Since then over 200 hundred people have claimed to have been one or other of the Romanovs (perhaps the most notorious being Anna Anderson who claimed to be Princess Anastasia), having escaped the slaughter of the rest of the family. Further speculation arose when the grave was finally examined in 1991 that only contained the remains of 3 and not all 5 of the children. However a second grave was found in 2007 and DNA analysis of these remains have found the 2 missing children, one of them Prince Alexei.
