injured girl, whom he treated at Cheka headquarters in Perm, told him, "I am the daughter of the ruler, Anastasia." Utkin obtained a prescription from a pharmacy for a patient named "N" at the orders of the secret police. White Army investigators later independently located records for the prescription. During the same time period in mid-1918, there were several reports of young people in Russia passing themselves off as Romanov escapees. Boris Soloviev, the husband of Rasputin's daughter Maria, defrauded prominent Russian families by asking for money for a Romanov impostor to escape to China. Soloviev also found young women willing to masquerade as one of the grand duchesses to assist in deceiving the families he had defrauded. Some biographers' accounts speculated that the opportunity for one or more of the guards to rescue a survivor existed. Yakov Yurovsky demanded that the guards come to his office and turn over items they had stolen following the murder. There was reportedly a span of time when the bodies of the victims were left largely unattended in the truck, in the basement and in the corridor of the house. Some guards who had not participated in the murders and had been sympathetic to the grand duchesses were reportedly left in the basement with the bodies. Romanov graves and DNA proof In 1991, the presumed burial site of the imperial family and their servants was excavated in the woods outside Yekaterinburg. The grave had been found nearly a decade earlier, but was kept hidden by its discoverers from the Communists who were still ruling Russia at the time. The grave only held nine of the expected eleven sets of remains. DNA and skeletal analysis matched these remains to Tsar Nicholas II, Tsarina Alexandra, and three of the four grand duchesses (Olga, Tatiana and presumably Maria). The other remains, with unrelated DNA, correspond to the family's doctor (Yevgeny Botkin), their valet (Alexei Trupp), their cook (Ivan Kharitonov), and Alexandra's maid (Anna Demidova). Forensic expert William R. Maples found that the Tsarevitch Alexei and Anastasia's bodies were missing from the family's grave. Russian scientists contested this conclusion, however, claiming it was the body of Maria that was missing. The Russians identified the body as that of Anastasia by using a computer program to compare photos of the youngest grand duchess with the skulls of the victims from the mass grave. They estimated the height and
