This monograph is an attempt at a comprehensive study of the fate of the remains of Nicholas II and his family who tragically died in Yekaterinburg in 1918. The data of genetic, forensic (anthropological) and dental examinations of the so-called "Yekaterinburg remains" are analyzed in detail. The materials and results of the examinations are correlated with known historical data and material evidence in the case, as a result of which not only the belonging of the "Yekaterinburg remains" to members of the royal family and their servants is confirmed, but also a fundamentally new conclusion is drawn about the absence among the discovered bones belonging to Nicholas II. The author substantiates the version about the destruction of the remains of the last emperor and his two children, Tsarevich Alexei and Grand Duchess Maria, at the Ganina Yama mine, as well as about the partial falsification of burial in the Porosenkov log near Yekaterinburg. The book is aimed at a wide readership – forensic experts, anthropologists, dentists, historians, source specialists, archivists, as well as anyone interested in the circumstances of the death of Nicholas II and his family.
