Abstract

The analysis of fire debris evidence might offer crucial information to a forensic investigation, when for instance, there is suspicion of the intentional use of ignitable liquids to initiate a fire. Although the evidence analysis in the laboratory is mainly conducted by a handful of well-established methodologies, during the last eight years several authors proposed noteworthy improvements on these methodologies, suggesting new interesting approaches. This review critically outlines the most up-to-date and suitable tools for the analysis and interpretation of fire debris evidence. The survey about analytical tools covers works published in the 2008-2015 period. It includes sources of consensus-classified reference samples, current standard procedures, new proposals for sample extraction and analysis, and the most novel statistical tools. In addition, this review provides relevant knowledge on the distortion effects of the ignitable liquid chemical fingerprints, which have to be considered during interpretation of results.

摘要

对火灾残骸证据的分析可能会为法医调查提供关键信息,例如,当怀疑有人故意使用可燃液体引发火灾时。尽管实验室中的证据分析主要通过一些成熟的方法进行,但在过去八年中,几位作者对这些方法提出了值得注意的改进,提出了新的有趣方法。本综述批判性地概述了用于分析和解释火灾残骸证据的最新且合适的工具。关于分析工具的调查涵盖了2008年至2015年期间发表的作品。它包括共识分类参考样品的来源、当前标准程序、样品提取和分析的新提议以及最新的统计工具。此外,本综述提供了关于可燃液体化学指纹失真效应的相关知识,在结果解释过程中必须考虑这些效应。
