Abstract

Purpose After sexual assault there is a limited amount of time before the DNA evidence on the surface of the victim’s body is not recoverable. During an assault, the offender may leave saliva on the victim’s skin. Traditional examination methods use a swabbing technique to collect saliva for DNA testing. Victim activity, especially hygiene activity such as showering, may negatively affect DNA recovery. Methods In this experiment, we compared two techniques for recovery of salivary DNA from the skin’s surface after a victim showers. We compared the traditional swabbing method to a ‘‘wet-vacuum’’ method using the M-Vac
