Why is the sexual assault kit done?
DNA is one type of evidence that may exist in sexual assault cases. When conducted within a certain time frame, the sexual assault kit is intended to collect any DNA evidence that exists from the assault. This evidence, when properly stored, can be evaluated by a forensic laboratory at a later date. If DNA is present, the profile developed from that DNA may be used to identify a suspect. If DNA is not present, it does not mean that the assault did not occur.
