火场血迹与血指纹显现方法研究进展
Research Progress on Recovery Methods of Bloodstains and Blood Fingerprints at Fire Scenes
摘要
Abstract
Blood is a common physical trace evidence at crime scenes.In a fire scene,bloodstains and blood fingerprints are often two of the most important means of identifying a person and establishing the identity of a suspect.However,the fire scene,due to its exposure,destructiveness,and the invisibility of the causal relationship between the traces,poses difficulties and challenges for the recovery of relevant physical evidence and the investigation of the fire.Although fire destroys various traces of physical evidence left at the scene to a greater extent,bloodstains and blood fingerprints can be recognized and extracted by chemical recovery methods and soot removal techniques.This paper presents a comprehensive overview of the methodologies employed in the identification and analysis of bloodstains and blood fingerprints at fire scenes.It specifically concentrates on three core aspects:the alterations in blood composition within fire environments,chemical recovery methods,and techniques for soot removal in fire scenes.Considering the investigative requirements of public security organs in fire-related crime scenes,this paper summarizes the research progress and applications of detecting and analyzing bloodstains and blood fingerprints found at fire scenes,with the aim of providing a valuable reference for public security organs to investigate fire-related cases.关键词
