The law enforcement agencies involved in these cases are then able to share the information obtained on each of the cases and possibly develop additional leads.Īs explained in SWGDAM’s recommendations “Moderate stringency CODIS matches, in general, have very low efficiency in locating true relatives in offender databases. If there is a candidate match in the Forensic Index, the laboratory goes through the confirmation procedures and, if confirmed, the match will have linked two or more crimes together. The DNA profile from the evidence is also searched against the state’s database of crime scene DNA profiles called the Forensic Index. If there is a candidate match in the Convicted Offender or Arrestee Index, the laboratory will go through procedures to confirm the match and, if confirmed, will obtain the identity of the suspected perpetrator. The forensic unknown profile attributed to the suspected perpetrator is searched against their state database of convicted offender and arrestee profiles (contained within the Convicted Offender and Arrestee Indices, if that state is authorized to collect and database DNA samples from arrestees). For example, in the case of a sexual assault where an evidence kit is collected from the victim, a DNA profile of the suspected perpetrator is developed from the swabs in the kit.
