In 2005, the OCCL, the OCDA and the Orange County Sheriff's Department participated in the NIJ DNA Expansion Demonstration Project. The purpose of the NIJ DNA Expansion Demonstration Program was to scientifically assess the contributions that DNA could make to solving high volume crimes and to identify cost-effective practices for collecting, analyzing, and utilizing DNA evidence to solve these crimes. Orange County focused on swabbing and analyzing DNA from items that had been handled or touched by suspects to determine the type(s) of items that more frequently provided probative DNA profiles.
