Home > 4. Combined DNA Index System (CODIS) > Summary
The benefits of searching for and supplying DNA profiles to the database include finding leads where none previously existed, linking cases to one another, and identifying suspects. DNA database hits have assisted thousands of investigations. CODIS works by comparing profiles at local, state and national levels. The use of John Doe warrants allows for the prosecution of a case if a suspect is identified after the statute of limitations' time limit expires.
