Abstract
Aim– development of a method implemented in the format of a computer program for determining the postmortem interval (PMI) by cranioencephalic temperature (CT) of a corpse under conditions of cooling with a single discrete decrease in ambient temperature. Material and methods. Analytical and finite element modeling of CT dynamics with a single discrete decrease in ambient temperature is performed. Results. A mathematical model has been developed for determining the PMI and the uncertainty of its estimates with a single discrete decrease in the ambient temperature. The values of the constants of the model equation and their variances are determined on the basis of finite element modeling of CT dynamics under the specified cooling conditions. The computational algorithm of the specified method for determining PMI and contraindications to its use are implemented in the C# language in the form of the Warm Bodies DSC program. Conclusion. The developed method and the application implementing it are recommended for use in forensic medical practice to determine the PMI with a single discrete decrease in ambient temperature.
