  Touch DNA evidence can be defined as DNA resulting from the transfer of epithelial cells from skin to an object. Due to its high success rate in recent years, such as the JonBenet murder case and Waldo rape case, touch DNA evidence has been increasingly studied. Sexual assaults, which generally involve unwanted sexual contact between the victim and the offender commonly go unreported and often the perpetrator cannot be identified because of lack of evidence. This study aimed to determine how touch DNA collected from a victim’s wrist after a simulated sexual assault changed over time. Sexual assaults were simulated with male “assailants” grabbing the left wrists of female “victims” while they struggled to free themselves from the grip. Samples were collected immediately and at 15-minute intervals thereafter for 120 minutes after assault an.. Read More»
