Three instances of estimation of postmortem interval using computer-assisted entomological techniques on the island of Oahu in the Hawaiian Islands are presented. While postmortem intervals were similar for all cases (4-5 1/2 days), recovery of the remains in differing habitats (xerophytic, mesophytic, and swamp) on the island resulted in significant differences in gross appearance of the remains, which could have resulted in the determination of different postmortem intervals in the absence of entomological techniques.

The excitability of skeletal muscle is a less-known post-mortem supravital phenomenon in human bodies, and it can be used to estimate the post-mortem interval. We conducted a field study in the Netherlands to investigate the applicability of muscle excitability (SMR) by mechanical stimulation for estimating the post-mortem interval in daily forensic practice. Knowledge concerning the post-mortem cell mechanisms accounting for the post-mortem excitability of skeletal muscle is lacking.

The age of the oldest immature insects present on a cadaver is typically used by forensic entomologists to estimate the minimum postmortem interval (PMI). The green bottle fly, Lucilia sericata (Meigen, 1826), known for its widespread distribution and necrophagy, is of considerable significance in forensic science. This study aimed to investigate potential regional developmental disparities between populations of L.

While estimating postmortem interval (PMI) ambient temperature plays a pivotal role, so its reconstruction is crucial for forensic scientists. The recommended procedure is to correct temperatures from the nearest meteorological station based on measurements from the death scene; typically applying linear regression. Recently, there have been attempts to use different algorithms, that can improve that correction, for example GAM algorithm.

Introduction: In the reconstructive phase of medico-legal human identification, the sex estimation is crucial in the reconstruction of the biological profile and can be applied both in identifying victims of mass disasters and in the autopsy room. Due to the inherent subjectivity associated with traditional methods, artificial intelligence, specifically, convolutional neural networks (CNN) may present a competitive option.
Objectives: This study evaluates the reliability of VGG16 model as an accurate forensic sex prediction algorithm and its performance using orthopantomography (OPGs).

Background: Verbal autopsy (VA) has been a crucial tool in ascertaining population-level cause of death (COD) estimates, specifically in countries where medical certification of COD is relatively limited. The World Health Organization has released an updated instrument (Verbal Autopsy Instrument 2022) that supports electronic data collection methods along with analytical software for assigning COD. This questionnaire encompasses the primary signs and symptoms associated with prevalent diseases across all age groups.
