The Combined DNA Index System (CODIS) is used to search against which profiles?

• A. Vehicle fingerprints
• B. Profiles of unknown samples collected in unsolved investigations
• C. A database of financial records
• D. Forensic hair samples only

Answer: (B)

CODIS is a tool for finding connections between cases and potential suspects by comparing DNA profiles. It stores DNA profiles from multiple sources, including convicted offenders, arrestees, and DNA from crime scenes. The system is designed to take unknown DNA profiles—such as those collected from an unsolved crime—and search them against all profiles in CODIS. If a match is found, investigators can link to a suspect or connect different crimes. The other options don’t fit CODIS’s purpose: it isn’t about vehicle fingerprints, financial records, or limited to hair samples; it centers on DNA profiles across casework and offender/arrestee data.
