Using Computed Tomography (CT) Scanning Technique in Forensic Entomology

0 Comment

This paper attempts to address threefold aims namely, to discuss the 1) techniques used in CT scanning, 2) limitations and 3) implications of such a method in forensic investigations. The seminal works of Keh serve as one of the pioneering studies concerning forensic entomology, and it includes the applications and scope of the said branch of medico-legal studies. Specifically, Keh defines forensic entomology as the study of insects and other arthropods associated with certain suspected criminal events. Although Keh states that studying the anatomical structures and transformations of insects in corpses may be the most effective way of determining the time of death, forensic entomology is not exclusive to studying insects in corpses. Instead, Keh asserts that forensic entomology may also include other animals, such as rodents, species of fish and birds, which may have attacked the corpse. Relatively, as a branch of forensic studies, forensic entomology corresponds to a range of investigations that focus on the identified species of animals residing in the body, which may provide details on the time of death. Recent studies on forensic entomology have investigated the use of specific medical instruments in enhancing the effectiveness of medico-legal investigations. Specifically, the studies by Jennings and Austin and Richards focus on the viability of using the CT scanning technique in identifying the traces of specific species of animals and insects found in carcasses. In the study by Jennings and Austin, primary research is conducted using the branches of the Tasmanian tree wherein they investigate the influence of woodwasps in the creation of tunnels in the tree’s decaying branches.
