The CODIS database contains several different indexes for the storage of DNA profile information. For assistance in criminal investigations three indexes exist: the offender index, which contains DNA profiles of those convicted of crimes; the arrestee index, which contains profiles of those arrested of crimes pursuant to the laws of the particular state; and the forensic index, which contains ...
In response to this congressional mandate, the FBI established the Combined DNA Index System ("CODIS"). The CODIS database provides a means for state and local forensic laboratories to share DNA profiles in an attempt to "link evidence from crime scenes for which there are no suspects to DNA samples of convicted offenders on file in the system ...
Jayann and Dave Sepich, Katie's parents, began researching the role of DNA in solving crimes. At first they just wanted to find and punish the person who had murdered their daughter; but as they learned more about how DNA can solve crimes, they also learned it could do so much more–it can prevent crimes and save lives.

CODIS can match DNA samples to potential suspects of different types of crimes. About 83% of the 1,584 sexual assault kits in the Wake County database since 2019 have now been tested, or 1,318 kits.
A record in the CODIS database, known as a CODIS DNA profile, consists of an individual's DNA profile, together with the sample's identifier and an identifier of the laboratory responsible for the profile. CODIS does not contain any personal identity information, such as names, dates of birth, or social security numbers.
In 2005, another effort to find the suspect by running those DNA samples through CODIS — a national database that law enforcement can use to link forensic profiles to crimes and suspects called ...

Partial DNA profiles can be a powerful tool, but the probability of a random match is larger than if a full profile was obtained. One method that has been developed to analyse degraded DNA samples is to use miniSTR technology. In the new approach, primers are specially designed to bind closer to the STR region. [32]
