The paper presents an overall report on the skull identification of paratroopers shot in Ressl Street, Prague. The victims, members of the underground group, assassinated R. Heydrich in June 1942. The skull identification is based on the paratroopers' photographies and, in particular, on the stomatological findings which was compared with the dentition visible in some photographs, especially those showing them smiling. None of the skully examined belonged to the actual assassins (J. Kubis, J. Gabcík). It is highly probable that they were those of the other members of the underground group.
