This article discusses a new DNA forensics technique that aims to measure a suspect's individual level of natural shedding of skin and other cells to aid in criminal investigations. Forensic experts are using cell staining to test how people shed varying levels of touch DNA. This research could potentially improve the accuracy of matching suspects to crime scene evidence.
A pioneering new DNA forensics technique is looking for a reliable method to measure a suspect’s individual level of natural shedding of skin and other cells to add to, and compare with, evidence collected at crime scenes. Using a novel technique of cell staining, forensic science experts have tested 100 people to confirm how people shed varying levels of touch DNA, from very low to very high.
