John Ramsey urges use of DNA technology to solve his daughter JonBenét's cold case murder.

John Ramsey, father of murdered 6-year-old JonBenét Ramsey, expressed hope after meeting with Colorado investigators, advocating for the use of genetic genealogy to review old evidence. This technology has solved other cold cases. Ramsey praised the Boulder Police Department's new leadership, believing it could lead to identifying his daughter's killer, who has not yet been charged in the 1996 murder.
