PLACERVILLE, Calif.—California authorities used recently developed DNA techniques to free one man and implicate another for only the second time in the United States, officials said Feb. 13.
A man who spent about 15 years in prison after being wrongfully convicted in the slaying of his housemate has been exonerated after authorities used extended DNA links developed through publicly available genealogical websites to build a family tree that led to the arrest of a new suspect.
