It was the cruelest and most mysterious crime in the history of Polish forensic science. The "coat" of human skin floating in the Vistula electrified the society and put the police all over the country on their feet. Detectives, clairvoyants, profilers, FBI officers were asked for help. It was not known for a long time who the victim was. In the end, it turned out that the murdered woman was a student of religious studies, 23-year-old Katarzyna Z. Her mother had been looking for her for several months.—G
