• Sexual Assault Kits with a CODIS Match: The foreign DNA profile from the sexual assault kit that was uploaded into the Combined DNA Indexing System (CODIS) matched the DNA profile of one or more DNA profiles within CODIS. This number can continually change as matches can happen indefinitely into the future. A match can be either a forensic match or an offender hit.

Please Note: For this purpose, all CODIS hits (both forensic and offender) are counted regardless of whether they provide a specific investigative lead for a particular case. The CODIS hit count includes each individual DNA profile match between cases, as well as each DNA profile match belonging to an offender. The metric 'total number of hits' is utilized to be able to demonstrate case connectivity and where hits are generating by county and those originating in other states. This may differ from how CODIS hits are counted for other reporting purposes.

• Forensic Match: The foreign DNA profile from the sexual assault kit that was uploaded into CODIS matched a DNA profile in the forensic index. The forensic index contains evidentiary profiles from crimes and are connected to incidents or cases and not to specific individuals.  Therefore, these matches represent connections between cases and may not provide information which identifies a suspect.
• Offender hit: The foreign DNA profile from the sexual assault kit that was uploaded into CODIS matched a DNA profile in the offender or arrestee index. The offender and arrestee indexes contain DNA profiles obtained at the time of arrest or conviction and are connected to a named individual. For the purposes of this project, offender hits can be classified as cold or warm hits. This terminology and sub-classification is different than current FBI/CODIS terminology.
