Virginia man linked to two murders committed almost 40 years ago. Elroy Harrison, 65, was charged with the murder of Jacqueline Lard, 32, in 1986.
He is also linked to the death of 18-year-old Amy Baker, 18, in 1989. Investigators said they used genetic genealogy to link Harrison to both murders. The technique allows investigators to compare DNA samples with public genealogical databases, narrowing lists of suspects to small geographic areas, families or individuals.
