Abstract

2014 Elsevier Ltd. All rights reserved. Time of death estimation is a fundamental problem in forensic medicine. A popular estimation method is by body cooling. In this article, we propose a compartment model for body cooling and that includes the well-known Marshall-Hoare model as a particular case. Using the Laplace transform, we give a new method for estimating the time of death from temperature readings only. We present the results of numerical simulations applied to theoretical and experimental data to show the accuracy of the proposed method.
