MICHAEL RUIZ: JonBenet Ramsey investigators are retesting evidence with newer technology, police chief says

Boulder investigators are retesting evidence in the 1996 murder of JonBenét Ramsey using newer DNA technology, Police Chief Steve Redfearn said this week. The case remains unsolved, with no one convicted in the killing. A cold-case review panel has brought local, state and federal investigators back to evidence tested decades ago, as advances in DNA analysis offer new avenues for identifying potential suspects.
