Attacks on humans by dogs in a pack, though uncommon, do happen, and result in severe, sometimes fatal, injuries. We describe the role that canine genetic markers played during the investigation of a fatal dog-pack attack involving a 50-year-old male truck driver in a parking lot in Tuscany (Italy). Using canine specific STR genetic markers, the local authorities, in the course of their investigations, reconstructed the genetic relationships between the dogs that caused the deadly aggression and other dogs belonging to the owner of the parking who, at the moment of the aggression, was located in another region of Italy.
From a Bayesian clustering algorithm, the most likely number of clusters was two. The average relatedness among the dogs responsible for the aggression was higher than the average relatedness among the other dogs or between the two groups. Taken together, all these results indicate that the two groups of dogs are clearly distinct. Genetic relationships showed that the two groups of dogs were not related. It was therefore unlikely that the murderous dogs belonged to the owner of the parking lot who, on grounds of this and additional evidence, was eventually acquitted.
成群的狗袭击人类的情况虽不常见，但确实会发生，且会导致严重伤害，有时甚至致命。我们描述了犬类基因标记在对一起致命的狗群袭击事件进行调查时所起的作用，该事件发生在意大利托斯卡纳的一个停车场，受害者是一名50岁的男性卡车司机。当地警方在调查过程中，利用犬类特异性STR基因标记，重建了引发致命攻击的狗之间以及与停车场所有者的其他狗之间的基因关系，而在攻击发生时，停车场所有者位于意大利的另一个地区。
通过贝叶斯聚类算法，最可能的聚类数为两个。引发攻击的狗之间的平均亲缘关系高于其他狗之间或两组狗之间的平均亲缘关系。综合来看，所有这些结果表明这两组狗明显不同。基因关系显示这两组狗没有亲缘关系。因此，那些行凶的狗不太可能属于停车场所有者，基于此及其他证据，停车场所有者最终被宣告无罪。
