[Finger prints on human skin--results of a general applications-oriented series]

Numerous methods have been described for making dactyloscopic traces visible on human skin, but these have never become routine--last but not least because they are too complicated and time-consuming to perform. The purpose of the present investigation was to find out to what extent fingerprints on the skin of deceased persons can be made visible with the help of conventional methods like iodine fuming or brushing with Magna-Brush and can be preserved with gelatine film or moulding material. Of the total number of 486 experimental fingerprints the dermal ridges could be made visible in 150 prints. The best findings were obtained when the trace had been applied several hours post mortem. On the skin of the extremities better results could be achieved than on the trunk or the neck. Dactyloscopic tracing on the skin of bodies in homicide cases should be taken into consideration especially if there is evidence that the perpetrator touched the victim after his/her death (e.g. if the body was transported).
