What does CODIS stand for in the context of criminal investigations?

In the context of criminal investigations, CODIS stands for Combined DNA Index System. This national database is used by law enforcement agencies to store and compare DNA profiles collected from crime scenes, convicted offenders, and missing persons. The primary goal of CODIS is to facilitate the sharing of DNA information across different jurisdictions, which can help in solving crimes and identifying individuals through genetic material.

The database includes various indexes that allow for the comparison of DNA samples. This system has proven to be a vital tool in modern forensic science, enabling law enforcement to link crimes, identify suspects, and provide evidence in criminal cases. The use of DNA evidence has revolutionized the way investigations are conducted, increasing the accuracy of identifications and convictions.

The other options do not accurately reflect the purpose or function of CODIS. They either reference systems that do not exist or use different terminologies that are not related to the established DNA indexing system used in criminal justice.
