The mitochondrial DNA from the skeletons was compared against mitochondrial DNA from relatives of the imperial family in the maternal line of descent, including the Tsarina's great-nephew Prince Philip, Duke of Edinburgh, and was found to be a match. Scientists believed that the matching DNA was enough to identify the remains of the Imperial Family and their servants. The "Yurovsky Note", a report filed by commander Yakov Yurovsky with his superiors following the murders, stated that two of the bodies were removed from the main grave and cremated at an undisclosed area. If the Whites ever discovered the grave, Yurovsky believed they would doubt the grave belonged to the Tsar and his retinue because the body count would be incorrect. Some forensic experts believe the complete burning of two bodies in so short a time would have been impossible given the environment and materials possessed by Yurovsky and his men. Initial searches of the area in subsequent years failed to turn up a cremation site or the remains of the two missing Romanov children.
