Abstract：
In most experimental protocols, false starts are produced on dry bones obtained through a maceration process for anthropological analyses, for the sake of reproducibility. Although this allows for controlled experimental conditions, the absence of soft parts when experimentally creating false starts does not correspond to the real conditions of criminal dismemberment. The main objective of this study was to determine if the results of experimental work on the characteristics of false starts were valid under medico-legal conditions. In this experimental study, a hand saw (rip saw, wavy set, TPI 32) was used. 240 false starts were produced on human and pig bones. Randomly, the false starts were either produced on a dry bone or on a flesh bone. The criteria for microscopic analysis included the shape of the walls, the shape and visibility of striae on the floor, the shape of the profile, and the minimum width of the false start. On human bone, 100% of the false starts produced on a bone that had previously undergone a maceration process for anthropological analyses (dry bone) allowed the definition of all the blade characteristics. This was the case for 78.3% on bone in the presence of soft tissue (flesh bone). The striae on the floor of the false start are in some cases less visible with flesh bones, implying that it may be more difficult to conclude on the characteristics of a saw under medico-legal conditions.
摘要：
在大多数实验方案中，在通过用于人类学分析的浸渍过程获得的干燥骨骼上产生错误的开始，为了重现性。虽然这允许受控的实验条件，在实验上制造错误的开始时，没有柔软的部分并不符合刑事肢解的实际条件。这项研究的主要目的是确定有关错误开始特征的实验结果在医学法律条件下是否有效。在这项实验研究中，手锯(撕裂锯，波浪形设置,使用TPI32）。在人和猪的骨头上产生了240个错误的开始。随机,错误的开始是在干燥的骨头上或在肉骨头上产生的。微观分析的标准包括墙壁的形状，地板上条纹的形状和可见性，轮廓的形状，和假开始的最小宽度。在人的骨头上，在先前经历过用于人类学分析的浸渍过程（干骨）的骨骼上产生的100％的错误开始允许定义所有叶片特征。在存在软组织(骨肉)的情况下,78.3%的骨就是这种情况。在某些情况下，假开始的地板上的条纹在肉骨头上不太明显，这意味着在医学法律条件下，很难就锯的特征得出结论。
