The mysterious demise of Russian princess Anastasia, the youngest daughter of Czar Nicholas II, was resolved today, at least to the satisfaction of a Russian panel. Participants declared she was killed during the Bolshevik execution of her family in 1918. Since then, several women have claimed to be Anastasia, insisting that the young girl survived the killing. Last year British experts conducting DNA tests on the remains of the royal family could only confirm the identities of the Czar, his wife and three of the four daughters. The more recent Russian study concludes that the bones of the Romanov son Alexei and his sister Maria, not Anastasia, were missing.
