Post-mortem interval (PMI) estimation is a critical component of death investigations but becomes particularly challenging in cases involving advanced decomposition, where traditional methods may prove less effective. The combined effects of severe tissue damage, environmental conditions, and interactions with carrion feeders complicate the PMI assessment. Forensic entomology has been utilized to address these challenges by focusing on insect colonization patterns and life cycle analysis. This article emphasizes the value of forensic entomology as an essential tool for estimating the PMI in complex cases involving extensive decomposition, offering a reliable complement to conventional forensic techniques. In addition, this article outlines a straightforward approach for deriving PMI estimates from available data when direct access to a forensic entomologist is not feasible.
死后间隔时间(PMI)的估计是死亡调查的关键组成部分,但在涉及高度腐败的案件中,这一过程极具挑战性,因为传统方法可能效果不佳。严重的组织损伤、环境条件以及与食腐动物的相互作用等综合因素,使得PMI评估变得复杂。法医昆虫学通过关注昆虫定殖模式和生命周期分析来应对这些挑战。本文强调了法医昆虫学在涉及广泛腐败的复杂案件中作为估计PMI的重要工具的价值,为传统法医技术提供了可靠的补充。此外,本文还概述了一种在无法直接联系法医昆虫学家时,根据现有数据得出PMI估计值的简单方法。
