Mock inquest1
Mock Inquest

  • 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
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

  • Students prepare experimental area in environment A

  • Two entomology groups sample, monitor and analyze arthropod and tissue samples

  • Model corpse is placed in secured cage surrounded by dead fall traps

  • Sampling will begin when first blow fly lands

  • Arthropods are sorted and counted.

  • Arthropod taxonomy is identified, and succession is determined.

  • Tissues are fixed and processed for paraffin embedding and stained.

  • .

Research activities in forensic taphonomy

  • Cell and tissue decay

  • Site formation processes

  • Chlorophyll concentration as PMI indicator

  • Hydraulic transport and differential preservation
