In 1991, the place where the Imperial family and their servants were supposedly buried as found in the woods outside Yekaterinburg. It had actually been found almost ten years earlier, but had been kept hidden by the people who discovered it. They did not want the Communists, who still ruled Russia at that time, to know where the grave was. The grave only had nine bodies instead of 11. DNA and studies on their skeletons showed that they were the bodies of Tsar Nicholas II, his wife, and three of the Grand Duchesses (Olga, Tatiana, and Maria). The other remains had different DNA. They were the bodies of the family's doctor (Yevgeny Botkin), valet (Alexei Trupp), cook (Ivan Kharitonov) and Alexandra's maid (Anna Demidova). Dr. William Maples decided that the Tsarevitch Alexei and Anastasia's bodies were missing. Russian scientists did not agree with this. They claimed that it was the body of Maria was missing, not Anastasia's. The Russians used a computer program to compare photos of Anastasia with the skulls from the grave. When some of the pieces of bone in the skulls were missing, they guessed how long or wide it was instead. American scientists thought this way of studying the bodies was wrong.
