W. Va. Code § 15-2B-2
It is the policy of this state to assist federal, state, and local criminal justice and law-enforcement agencies in the identification, detection, and exclusion of individuals who are subjects of the investigation or prosecution of violent crimes, sex-related crimes, and other crimes against the person. In furtherance of such assistance, the Legislature finds:
That the analysis of DNA contained in biological evidence that may be recovered from a crime scene facilitates such identification, detection, and exclusion;
That the comparison of DNA data recovered from a crime scene with existing DNA records maintained in a central DNA database further facilitates such identification, detection, and exclusion; and
That requiring individuals convicted of certain crimes to provide a sample for DNA analysis with the resulting eligible DNA records maintained in a central DNA database will likewise further facilitate the aforementioned identification, detection, and exclusion and may serve to discourage recidivism.
Therefore, the Legislature finds that assisting federal, state, and local criminal justice and law-enforcement agencies through the use and development of DNA analysis is of the utmost importance and urgency in this state and that a DNA identification system shall be established as described in this article.
