“…Benecke et al [22,56] reported three cases in which differential diagnoses between bloodstain patterns and FAs were crucial in determining the manner of death. The same authors described some features of FAs (e.g.…”

“…stains without a distinguishable tail and body, stains that do not participate in directional consistency with other stains that suggest a point of convergence at a point of origin) that can be useful for distinguishing the FAs from the bloodstains. However, these features are still the matter of debate [53,57].…”

Crime scene and body alterations caused by arthropods: implications in death investigation

The activity of arthropods on corpses has been largely investigated, since they can produce information to reconstruct the perimortem events. However, the feeding/movement activity of insects around the crime scene, among the clothes and on the body, can also cause some alterations that can lead to wrong reconstruction and misinterpretations. This article summarises all the postmortem arthropods artefacts related to the scene (i.e. fly artefacts and floor stripes) and the body (i.e. skin and other soft tissue alterations, bone alterations and hair alterations) that can mislead the forensic pathologist, discussing macroscopic and microscopic findings derived from forensic casework and from experimental laboratory studies, in order to provide a useful instrument to avoid misinterpretations and evaluation errors. Finally, some procedural notes for the documentation and the interpretation of findings are proposed.

“…Second, forensic techniques must operate in the context of investigative procedures and the legal framework, rather than as an isolated scientific procedure. Benecke cited a German murder case, involving a mother and child found dead in the living room of their house in Cologne on 30 January 2001, in which both of these integrative dimensions featured prominently (Benecke & Barksdale, 2003). One legal requirement was the need to know which of the victims died first, to establish rights of inheritance.…”

Insects as vectors of DNA in a forensic context

Insects have historically been used in criminal investigations to provide information in relation to postmortem intervals (PMIs) but the field of forensic entomology is expanding. It is now recognized that insects can act as vectors of human and mammalian DNA through the consumption of biological material, with extraneous DNA able to be extracted and genotyped from all stages of the life cycle, and insect feces and regurgitant (artifacts). To date, DNA recovered from insects have been used to inform investigations into neglect and homicide, link body parts, and to identify victims of crime. It may also potentially be used to identify assailants, confirm the food source of insects to determine their relevance in PMI calculations, determine if a crime has occurred, identify scenes of crimes, and link people to locations and other individuals. However, insects which have consumed biological material may also transfer DNA by traveling to new areas, or depositing it via their artifacts, either within crime scenes or laboratories, or at locations distant to the food source. This could contaminate forensic evidence, confound investigations, and/or falsely incriminate or exclude an individual. Therefore, it is important that there is increased awareness into both the utility of insects as vectors of forensically relevant DNA, and the potential for contamination.
