Our students have recently been putting theory into practice again, this time learning about the CSI role of the forensic entomologist.
Year 12 Criminology students took part in a supervised forensic science experiment in taphonomy. This experience has allowed the group to gain a practical understanding of how forensic entomologists help investigators estimate timelines and interpret crime scenes. Using chicken carcasses in a secure and controlled outdoor setting, they observed how environmental conditions affected decomposition and insect activity, including blowfly development.
The investigation included three scenarios. What happens to a carcass with a simulated knife wound left in the open? What happens to a carcass partially submerged in water? And what happened to the carcass representing an arson attack?
In groups, the students were asked to monitor one of the carcasses, make notes on its deterioration, apply what they had learnt in class. They were also asked to find case studies of entomological cases and reflect on the lifecycle of the blowfly as well as researching other insects that might be of use to a forensic scientist.
Here are some highlights from the presentations they were asked to compile (click on any of the images to enlarge them):
