Cosmetic products often contain glitter or shimmer glistening components that may transfer during intimate contact. Glitter and shimmer might be confused as the same by the consumer market, but they are chemically different products. Glitter analysis has been previously explored and documented, but research is limited on the forensic analysis of sh...

Perpetrators are often aware of commonly used trace evidence in forensic casework, thereby limiting potential transfer during a crime. With the lack of common evidence left behind at a crime scene, consideration of alternative potential evidence is necessary. Glitter and shimmer particles from cosmetic products will potentially transfer from or ont...

With the common knowledge of DNA and fingerprints being used as trace evidence in casework, many perpetrators attempt to mitigate the transfer of such evidence at a crime scene. However, since close personal attacks are common, it is necessary to account for the potential lack of such evidence that may associate a suspect to a crime scene by consid...

This paper investigates three color tests, for a novel gunshot residue (GSR) detection protocol, which produces a color reaction to the organic gunshot residue (OGSR) components while preserving the inorganic gunshot residue (IGSR) for SEM-EDX analysis. The presence of both I/OGSR residues could potentially identify suspects in criminal investigati...
