The "Yurovsky Note" showed that two of the bodies were taken from the main grave and burned secretly to hide the burials of the Imperial family. However, people could not find the place where the bodies were burnt for many years. However, on 23 August 2007, a Russian archaeologist declared that he had found two burned skeletons near Yekaterinburg, at a place which seemed to match what was described in Yurovsky's writings. The archaeologists said that the bones were from a boy who was about 10 to 13, and a young woman who was between 18 and 23 years old. Anastasia was 17 years and one month old when she was killed; Maria was 19 years, one month old, and Alexei was just two weeks before his fourteenth birthday. Anastasia's older sisters, Olga and Tatiana, were 22 and 23 when they died. They used metal detectors to find the bones.
