DNA evidence exonerates wrongly convicted California man who spent 14 years in jail for murder
Key points: Ricky Davis's murder conviction is thrown out of court after DNA evidence pointed to a new suspect
Sacramento County district attorney Anne Marie Schubert attributed Mr Davis' exoneration, and the arrest of a new suspect, to the use of genetic and genealogical science.
Ms Hylton was found dead on July 7, 1985, inside an El Dorado Hills home, which she lived in with her teenage daughter, Mr Davis and Mr Davis' then-girlfriend Connie Dahl.
The test results excluded Mr Davis, Ms Dahl and Ms Hylton's daughter as the sources of the DNA, the project said.
