Forensic entomology is a branch of applied entomology that uses insects found on corpses or elsewhere around crime scenes in the interest of forensic science. This includes studying the types of insects commonly found on cadavers , their life cycles, their presence in different environments, and how insect assemblages change with decomposition .
A case that shaped Canadian judicial history and brought forensic entomology into the headlines was the exoneration of Steven Truscott forty-eight years after being indicted for murder. [12] Forensic entomology also played a role in the investigation of the 1993 raid on David Koresh and the Branch Davidians. [5]
Entomological evidence collection is the process of collecting evidence based on insect clues used in criminal investigations.If evidence is not carefully preserved at a crime scene after a death, it may be difficult or impossible for an entomologist to make an accurate identification of specimens, if for example, all morphological characteristics are not preserved.
Forensic entomological decomposition is how insects decompose and what that means for timing and information in criminal investigations.Medicolegal entomology is a branch of forensic entomology that applies the study of insects to criminal investigations, and is commonly used in death investigations for estimating the post-mortem interval (PMI).
The field of forensic entomology is an ever-expanding one. As more case studies are presented and more research is conducted the ability to use insects as determining evidence in cases of abuse or neglect grows. Currently, the use of insects as indicators of abuse or neglect is not a common occurrence.
In forensic entomology, entomotoxicology is the analysis of toxins in arthropods (mainly flies and beetles) that feed on carrion.Using arthropods in a corpse or at a crime scene, investigators can determine whether toxins were present in a body at the time of death.
Forensic limnology is a sub-field of freshwater ecology, which focuses especially on the presence of diatoms in crime scene samples and victims. Different methods are used to collect this data but all identify the ratios of different diatom species present in samples and compare those samples with the location of a crime scene.
Marine Forensic Science is forensic science applied to legal issues involving marine life. It also refers to the scientific study and investigation of human incidents, accidents, or deaths occurring as a result of or involving bodies of water including oceans, streams or rivers, lakes, or ponds. [1]
