According to the DNA Initiative’s Web site, databases that contain DNA profiles “have greatly enhanced law enforcement’s profiles, against which DNA profiles developed from crime scene evidence can be compared.”4
The Federal Bureau of Investigation’s Combined DNA Index System (CODIS) software enables state, local, and national law enforcement forensic laboratories to search each other’s databases, thereby comparing DNA profiles electronically. Jurisdictions can link serial crimes to each other and identify suspects by matching DNA profiles from crime scenes with profiles from convicted offenders. Each state has a statutory provision for the establishment of a DNA database.
