A young woman was found unconscious in her flat strangulated with a children's scarf and was at first thought to be dead. The victim survived but is disabled for life. Neither bloodstaines nor sperm were found at the scene. Swebs of fleece were prepared from two fingers of a one-way glove which were found at the scene and from each end of the scarf in order to find some epithelial cells from the criminal. DNA was extracted and amplified by the polymerase-chain-reaction (PCR). The DNA-profile of the victim as well as that of the suspected apart living husband were found in these mixed stains. The suspect was severely incriminated by these findings and other evidence. Consequently the court convicted him to eleven years of inprisonment because of attempted manslaughter.
