What is a common use of the Combined DNA Index System (CODIS)?

Tracking missing persons
Analyzing drug samples
Connecting DNA evidence from crime scenes to offenders
Monitoring sex offender registries

The correct answer is: Connecting DNA evidence from crime scenes to offenders

The Combined DNA Index System (CODIS) serves a vital role in the criminal justice system by facilitating the connection of DNA evidence from crime scenes to known offenders. This powerful tool enables law enforcement agencies to compare DNA profiles gathered from crime scenes against a database of previously collected DNA profiles from convicted offenders, arrestees, and unidentified human remains. When a match occurs, it can provide crucial evidence linking an individual to a specific crime, thereby aiding in investigations and prosecutions. While there may be other systems or methods used for tracking missing persons, analyzing drug samples, or monitoring sex offender registries, these functionalities do not fall within the primary scope of CODIS. CODIS is uniquely focused on the comparison and matching of DNA profiles in relation to criminal investigations, reinforcing its significance in solving cases involving violent crimes, sexual assaults, and more.
