The second major category, is criminal cases. We can link a suspect to a rape or homicide. Equally important, we can exonerate innocent people wrongly accused of a crime. We also have used DNA to identify homicide victims, or body parts to find out the identity of the person. Another powerful application is cases where we have no suspects.
Many states have DNA data banks.
Let's say a victim was raped and she cannot identify who is the attacker. Through DNA searches in the data bank, we can look at sex offender data banks. Each case, for the victim's family, that's the most important case to them. Each case to the defendant, that's the most important case to them. All those cases I've worked on, they all have an interesting twist.
