The document discusses LODISTM, a local DNA database system that allows law enforcement agencies to access DNA testing for investigations even without suspects. It describes how LODISTM works through a simple three-step process of collecting DNA samples, submitting them, and using the results to investigate cases. Pilot programs saw doubled suspect identifications, arrests, and prosecutions compared to traditional investigations. LODISTM provides a cost-effective way for local agencies to make more use of DNA testing.
