How does CODIS work?

Once a DNA profile is developed, this profile can be searched against a database of convicted offender DNA profiles. If the DNA profile matches with a convicted offender, the laboratory will need to confirm the match and obtain the identity of the suspect. The DNA profile can also be searched against a database of crime scene DNA profiles. If there is a match through this database, the laboratory will need to confirm the match. If this match is confirmed, it will link the two crime scenes together.
