The unsolved 1996 murder of six-year-old JonBenét Ramsey has returned to public attention following the guilty plea of a discredited Colorado DNA analyst, a development that has intensified calls to apply modern forensic techniques to the case. Her father, John Ramsey, is renewing his appeal for advanced DNA testing—specifically forensic genetic genealogy—which he believes could finally identify his daughter's killer, and he has publicly urged President Donald Trump to intervene to help solve the decades-old case.

The laboratory scandal has added weight to concerns about the handling of forensic evidence and increased pressure on authorities to pursue newer methods that were not available at the time of the crime. Forensic genetic genealogy, which combines DNA profiling with genealogical databases, has been credited with resolving other long-dormant cases, including a recent arrest in the 1988 killing of an Orlando woman after nearly four decades. John Ramsey argues these techniques offer the best remaining hope of a breakthrough in his daughter's case.
