The fibre traces on a young victim found underwater were mostly single fibre traces besides small amounts of fibre collectives indistinguishable from his parents clothes (mainly wool). Most of those single fibre traces were blue-grey polyester fibres showing tiny differences among each other. They were unexpected according to known population fibre studies. One year after the victim's discovery experiments were conducted to evaluate the possible contamination with fibres from river water. A small amount of extraneous fibres were collected among which blue and grey-black cotton and man-made (mainly polyester) fibres. All man-made fibres were single fibre traces and small fibre collectives were only observed for cotton. These results confirmed the frequent occurrence of blue and grey-black cotton fibres as background, but also highlighted the possible contamination with single blue and grey-black man-made fibres from river water. No wool was found, strengthening the significance of the wool fibre collectives present on the victim.
在水下发现的一名年轻受害者身上的纤维痕迹，除了少量与他父母衣服（主要是羊毛）难以区分的纤维聚集体外，大多是单根纤维痕迹。这些单根纤维痕迹大多是蓝灰色聚酯纤维，彼此之间存在细微差异。根据已知的总体纤维研究，这些痕迹是出乎意料的。受害者被发现一年后，进行了实验以评估河水纤维可能造成的污染。收集到少量外来纤维，其中有蓝色和灰黑色的棉纤维以及人造纤维（主要是聚酯纤维）。所有的人造纤维都是单根纤维痕迹，仅在棉纤维中观察到了小的纤维聚集体。这些结果证实了蓝色和灰黑色棉纤维作为背景的频繁出现，但也突出了河水可能带来的蓝色和灰黑色单根人造纤维污染。未发现羊毛纤维，这强化了受害者身上羊毛纤维聚集体的重要性。
