It depends on the type of hit. If there is a CODIS hit to a known offender whose DNA is already in CODIS, investigative follow-up typically occurs to determine that person’s potential involvement. If, however, there is a CODIS hit to another case, this is known as a forensic hit. In this scenario, a suspect would only be identified of one of the matched cases has a known suspect or known offender. If not, the hit only confirms that the two crimes were likely committed by the same person, but that person’s identity is unknown.
