Just DNA Searches In CODIS

In episode three of our 2023 Sexual Assault Awareness Month mini season, Just Science sat down with Orlando Salinas, Lieutenant Trampas Gooding, and Jennifer Pollock from the Texas Department of Public Safety to discuss how statutes regarding lawfully owed DNA and familial DNA searches are utilized in sexual assault investigations. When an unknown DNA profile is found in samples collected within a sexual assault kit, the unknown profile is searched within national DNA databases such as the Combined DNA Index System or CODIS. To ensure a comprehensive national database and enhance its use as an investigative tool, all states have legislation requiring the collection of DNA from known offenders of qualifying offenses and subsequent entry into CODIS. Some states also allow the use of familial DNA searching in CODIS. Listen along as Orlando, Lieutenant Gooding, and Jennifer describe how they collect lawfully owed DNA samples, conduct familial DNA searches, and talk about specific cases that were solved by using these investigative tools.
