What is CODIS primarily used for?

CODIS, which stands for Combined DNA Index System, is primarily used for managing DNA profiles of known offenders and unknown samples, such as those obtained from crime scenes. This system allows law enforcement agencies to compare DNA profiles from different jurisdictions, aiding in the identification of suspects and in connecting various crimes to a single perpetrator. By maintaining a centralized database of DNA profiles, CODIS significantly enhances investigative efficiency and effectiveness in solving crimes.

The emphasis on DNA profiles highlights the importance of genetic material in modern forensic science. This system is critical in criminal investigations, particularly in cases of sexual assault, homicides, and other violent crimes where biological evidence is often present.

In contrast, the other mentioned options do not align with CODIS's primary function. While storing fingerprints could involve a separate database, developing crime scene profiles relates more to the broader investigative process rather than the specific functions of CODIS. Additionally, packaging crime scene evidence pertains to the collection and preservation of evidence rather than DNA profile management.
