If the DNA profile from a crime scene matches an offender's profile in CODIS, there are three possible outcomes:
- The match may link two or more unsolved cases, which allows investigators to coordinate their activities.
- The match may link a solved case with an unsolved case.
- The match may link two or more solved cases, which would be useful information to prosecutors in the adjudication of each case.
Remember: One hit can link multiple investigations. For example, a single hit in Minnesota linked 16 crime scenes to one suspect.
