Investigative Field Techniques Forensic Archeology
Each forensic team submits a written forensic case report. Students portray expert witnesses and defend their conclusions. Afterwards, crime scenario is presented and compared to forensic team findings.
Model Human Corpse Hormel pygmy pig is used as a model human corpse Document arthropod succession is used to determine post-mortem death interval Patterns of decomposition and disarticulation are documented The model corpse is used for other research purposes (e.g. studies in taphonomy)
Forensic Entomology Model corpse is placed in secured cage surrounded by dead fall traps Sampling will begin when first blow fly lands Students prepare experimental area in environment A Two entomology groups sample, monitor and analyze arthropod and tissue samples
Traps are sampled at set times in morning and afternoon. Temperature, rainfall and other climatic variables are measured. Arthropods are sorted and counted. Arthropod taxonomy is identified, and succession is determined. Tissues are fixed and processed for paraffin embedding and stained..
