How does CODIS work? For example, a sexual assault is committed and an evidence kit is collected from the victim. A DNA profile of the perpetrator is developed from the sexual assault evidence kit. If there is no suspect in the case or if the suspect's DNA profile does not match that of the evidence, the laboratory will search the DNA profile against the convicted offender index. If there is a match in the convicted offender index, the laboratory will obtain the identity of the suspected perpetrator. If there is no match in the convicted offender index, the DNA profile is searched in the forensic or crime scene index. If there is a match in the forensic index, the laboratory has linked two or more crimes together and the law enforcement agencies involved in the cases are able to pool the information obtained on each of the cases.

One of the underlying concepts behind CODIS is to create a database of a state's convicted offender profiles and use it to solve crimes for which there are no suspects. Recognizing this, as early as the late 1980's, the states began to enact laws that required offenders convicted of sexual offenses and other violent crimes to provide DNA samples. These DNA samples were to be analyzed and entered into state DNA databases. As you know, all fifty states now have such DNA database laws

The DNA Identification Act of 1994
provided the statutory authority for creation of the National DNA Index System (NDIS) and specified the type of data that could be included in this national index. Only the following types of DNA data may be stored in the national index administered by the FBI Director:
* DNA identification records of persons convicted of crimes;
* analyses of DNA samples recovered from crime scenes;
* analyses of DNA samples recovered from unidentified human remains; and
* analyses of DNA samples voluntarily contributed from relatives of missing persons. See 42 U.S.C.S. §14132(a).
In accordance with the DNA Act, the FBI recommends that states include all felony offenders and misdemeanor sex offenders within the scope of their database laws. A review of other states' experiences indicate that it is valuable to include what may not be traditionally characterized as violent felony offenses, such as burglary and some drug-related offenses. States have been identifying offenders for subsequent offenses based upon their inclusion in the DNA database for such non-violent felonies.
