摘要:

血迹是暴力犯罪现场重要的生物物证,包含了丰富的犯罪信息。相对准确的血迹遗留时间推断对于还原案发时间,确认或排除相关人(物)与案件的关联具有重要意义。近年来,国内外研究者从血迹图像特征、生物化学特征等方面对血迹遗留时间进行了大量研究。本文综述了近二十年来推断血迹遗留时间的方法,并讨论这些方法应用于侦查实践中所存在的障碍,同时对血迹遗留时间推断技术的发展进行展望。

Abstract:

Bloodstains are important biological evidence at violent crime scenes and contain rich information about the crime. The relatively accurate estimation of bloodstain age is of great significance for estimating the time of the crime, confirming or excluding the association of relevant persons (objects) with the case. In recent years, researchers at home and abroad have conducted extensive studies on the bloodstain age estimation from the aspects of bloodstain image and biochemical characteristics. This paper reviews the methods of bloodstain age estimation in the past two decades, discusses the obstacles of these methods in investigative practice, and provides an outlook on the development of bloodstain age estimation technology.
