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, Minnesota has more than 170,000 convicted offenders in CODIS, which has aided in over 9,300 investigations across the United States.
