Forensic Evidence: A Case Study

Good Essays

Autopsies and post-mortem examinations range back to the 2nd century. Throughout the years, autopsies became more accurate with the advancement of technology. As technology advances, the need for autopsies is questioned. The most useful tool in the examination of the deceased is Post-Mortem Computed Tomography (PMCT). Computed tomography is an imaging procedure that creates detailed scans and pictures of the body. There is currently a debate on whether PMCTs will make the need for a forensic autopsy extinct. Several experiments and case studies have been done on this topic. The most common outcome for studies comparing the two concludes that PMCTs should not replace the need for autopsies, but instead should be used with autopsies when finding …show more content…

In this study, the researchers performed an experiment to assess how accurate post-Mortem Computed Tomography (PMCT) is at detecting lethal lesions versus a forensic standard autopsy (SA). The study consisted of 236 corpses. The corpses were first examined by PMCTs and then examined by two forensic experts. Table 1 on page 1830 organizes the causes of death. Table 2 provides the data collected from both the PMCTs and SAs. Conclusions from PMCT were reliable across examiners because concordance between the findings of the two radiologists was almost perfect or substantial in determining each type of lesion. “…Autopsy can show lesions missed by PMCT, it is able to demonstrate lesions that are not observed at autopsy because some anatomical locations are not routinely dissected or specialised manoeuvres are not routinely performed” (1832). In this study, the correlation between autopsies and PMCTs are almost perfect. PMCTs are good in detecting skeletal injuries. PMCTs are very accurate in detecting trauma to the skull. The results of this study concluded that “PMCT are effective in determining lethal lesions detected by autopsy in the context of craniofacial trauma or gunshot wounds but was less accurate after stab wounds, sometimes showing only indirect signs as effusions in anatomical cavities” (Blanc-Louvry et …show more content…

“This study describes typical findings in post-mortem imaging of opioid abusers. The results support the inclusion of forensic radiology in death investigations and suggest that PMCT may be a useful tool for interpreting opioid related deaths. Although it is not yet a replacement for conventional autopsy, if the approach can be validated in prospective studies, PMCT may help to reduce the number of forensic autopsies” (1281). The control group was matched to the study group with respect to age and sex, and included 55 decedents who also underwent whole-body PMCT prior to autopsy. Decedents who were tested positive for heroin (and its metabolites), methadone, or any other illegal drug, were excluded from this group (1281). In conclusion, the study demonstrates frequent findings of post-mortem whole-body MSCT in cases of fatal opioid intoxication that are in line with clinical experiences in instances of opiate overdose
