It was the second time this year that Alaska investigators used new DNA technology called genetic genealogy to crack a cold case. To help with the testing, the state hired a Virginia-based company called Parabon NanoLabs. The company analyzes crime scene DNA and tries to match it to databases supplied by people who have taken ancestry tests, or given other types of genetic samples.
Steve Armentrout, Parabon chief executive, says it’s a new science that’s expanding quickly.
