This document discusses the use of insects in estimating time of death and their role in forensic investigations. It begins by outlining the history of forensic entomology from its discoveries in the 17th century. Different types of insects, like flies and beetles, arrive at a body at different times post-mortem and under varying environmental conditions, allowing investigators to estimate time since death. Proper collection and documentation of insect evidence is also discussed. The document concludes by noting the diversity of contexts in which forensic entomology can provide insights, such as cases of abuse, accidents, or toxicology.
Forensic Entomology
- 1. By: Ashley Straniero & Shaun Connolly
- 2. From the Beginning First discovered by Francesco Redi (17th Century) Exposed vs. Unexposed Meat Spontaneous Generation Theory
- 3. Insects at the Crime Scene Flies vs. Beetles Blow Flies and Flesh Flies are first to inhabit a body (Calliphoridae and Sarcophagidae) (Sexton beetle)
- 4. Weather and Observations of Body Sun vs. Shade Position of Body Inside vs. Outside Maggot Mass Temperature Air Temperature Soil Temperature
- 5. Collection of Bugs First appeared bugs are captured first (very fast retrievers) Ethyl Acetate to immobilize bugs (75%) Properly label bugs (graphite only)
- 6. Estimating Time of Death PMI (Post Mortem Interval) Identifying types of species of insects Rate of development Tampering with the results: season, temperature, sun exposure, etc.
- 7. Sequence of Insect Arrival 1st Responders=Blow Flies which are attracted to the foul odor (several hours after death) 2nd Responders=Flesh Flies appear directly after or at the same time as Blow Flies Under certain weather conditions, the Flesh Fly will appear first since they can fly during rainfall.
