CODIS stands for Combined DNA Index System. This is a national database comprised of several indexes including DNA profiles of convicted offenders, profiles developed from evidence in unsolved crimes, and profiles developed for the identification of missing persons. CODIS automatically searches these indexes for matching DNA profiles. When a match, or “hit”, occurs to the convicted offender index law enforcement can coordinate to learn the identity of the suspect.
Minnesota Statue 609.117 requires all felony level offenders to provide a biological specimen for the purpose of DNA analysis. The CODIS section at the Bureau of Criminal Apprehension is responsible for receiving, analyzing, verifying, and uploading DNA samples from convicted offenders to the national database. Currently, the BCA has more than 120,000 convicted offenders in CODIS, which has produced over 3,800 hits, assisting investigations in at least 39 states and 2 Federal agencies.
