Matching crime-scene DNA to data in a genealogy site recently helped cops nab a suspect in a decades-old murder case referred to as the Golden State Killer. Now, scientists say, the technique could be used to identify more than 60 percent of US citizens with European ancestry by a given DNA sample.
“In a few years, it’s really going to be everyone,” study coauthor Yaniv Erlich, a computational geneticist at Columbia University, tells Science.
