Gold standard for the estimation of the time since death in the early postmortem period is the temperature based nomogram method together with time of death dependent criteria of postmortem lividity, rigor mortis and supravital reactions. There is also a huge literature on chemical methods proposed for estimating the time since death which however play obviously no role in forensic practice. Especially the rise of vitreous potassium has been studied intensively. Also immunohistochemical methods have been proposed for estimating the time since death but obviously not yet applied in casework. We present a case where a woman was found murdered 8 days after having been seen last alive. Due to lack of putrefactive changes postmortem interval was thought to be not more than 2 days. However, immunohistochemical stainings and vitreous potassium concentration revealed that time since death was more than 6 days and the woman was obviously murdered immediately after she was seen lastly alive.
在死后早期阶段，评估死亡时间的金标准是基于温度的列线图方法，以及与死后尸斑、尸僵和存活反应有关的死亡时间依赖性标准。也有大量关于化学方法的文献被提出，用于估计死亡时间，但这些方法在法医学实践中显然没有发挥作用。特别是玻璃体钾的升高已经被深入研究。也有提出用于估计死亡时间的免疫组织化学方法，但显然尚未在案例工作中应用。我们报告了一个案例，一名妇女在最后一次被看到活着 8 天后被发现被谋杀。由于没有腐败变化，推断死后间隔时间不超过 2 天。然而，免疫组织化学染色和玻璃体钾浓度显示，死亡时间超过 6 天，该妇女显然是在最后一次被看到活着后立即被谋杀的。
