摘要

在大多数实验方案中,为了保证可重复性,都是在通过浸渍过程获得的干骨头上制作假肢,用于人类学分析。虽然这样可以控制实验条件,但在实验中制作假开端时没有软的部分,这并不符合犯罪肢解的真实情况。本研究的主要目的是确定关于假开端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,使用的是手锯(波形锯,TPI 32)。在人骨和猪骨上制作了 240 个假锯。随机在干骨或肉骨上制作假开端。显微分析的标准包括骨壁的形状、骨底条纹的形状和可见度、轮廓的形状以及假开端的最小宽度。在人类骨骼上,100% 的假齿都是在经过人类学分析浸渍处理的骨骼(干骨)上产生的,因此可以确定所有的刀片特征。而在有软组织(肉骨)的骨头上,78.3%的误判率也是如此。在某些情况下,肉骨上锯齿底部的条纹不太明显,这意味着在医学法律条件下可能更难确定锯齿的特征。

Comparison of false starts by saw created on flesh and dry bones; as close as possible to the real conditions of criminal dismemberment.

Comparison of false starts by saw created on flesh and dry bones; as close as possible to the real conditions of criminal dismemberment.

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.

期刊介绍: The International Journal of Legal Medicine aims to improve the scientific resources used in the elucidation of crime and related forensic applications at a high level of evidential proof. The journal offers review articles tracing development in specific areas, with up-to-date analysis; original articles discussing significant recent research results; case reports describing interesting and exceptional examples; population data; letters to the editors; and technical notes, which appear in a section originally created for rapid publication of data in the dynamic field of DNA analysis.
