Former Forensic Analyst Sentenced to 10 Years as Evidence Tampering Reopens Cold Cases, Including the Infamous JonBenét Ramsey Investigation

Denver, Colorado — A significant development in the long-standing investigation into the unsolved murder of JonBenét Ramsey emerged on September 8, 2026, when a judge sentenced Yvonne “Missy” Woods to ten years in prison. The former forensic DNA analyst, who had worked for the Colorado Bureau of Investigation (CBI) for nearly 30 years, admitted to manipulating evidence, prompting the reopening of numerous closed cases statewide.

Woods, 66, reached a plea agreement in June where she pleaded guilty to four felonies, including cybercrime and forgery, exposing her to a possible sentence of eight to 16 years. The judge ordered the prison terms for her other counts to run concurrently and added three years of mandatory parole. The plea deal also resulted in the dismissal of 100 additional charges.

Investigators revealed that Woods falsified DNA results and tampered with forensic records in cases dating back to 2008. Her actions allegedly affected as many as 1,045 cases in Colorado, with around 10% of her substantial caseload of over 10,000 cases encountering issues due to her misconduct. District Attorney Alexis King stated that Woods has acknowledged the extent of her wrongdoing, which spanned multiple decades.

In the wake of Woods’ sentencing, Denver officials announced that they are reopening 13 closed sexual assault cases linked to her work. Initial retests have yielded eligible DNA profiles for the Combined DNA Index System (CODIS), resulting in new investigative leads in six cases. The ramifications of Woods’ actions have already led to one major judicial reversal; Michael Clark’s conviction for a 1994 murder was vacated in April 2026 after it was determined that evidence from Woods had significantly influenced his trial.

Despite the scrutiny surrounding Woods’ misconduct, Boulder police confirmed that a review of evidence related to the Ramsey case revealed no direct impacts. Although Woods was employed at the CBI during the investigation, there is no documentation of her handling evidence in the high-profile case, as key DNA samples were sent to an external lab, shielding them from the consequences of her actions.

However, law enforcement in Boulder is actively revisiting the evidence with hopes that advancements in forensic technology can finally yield results. The Boulder Police Department is exploring modern testing methods at independent labs and is continuing to follow new leads, engaging with the Colorado Cold Case Review team to ensure no stone is left unturned.

JonBenét Ramsey’s father, John Ramsey, remains resolute in his quest for answers nearly 30 years after his daughter’s tragic death. Following Woods’ sentencing, he expressed skepticism about the police’s approach, advocating for the use of specialized private laboratories for DNA testing. Ramsey believes that the killer’s identity is known but has yet to be confirmed, as DNA evidence discovered at the crime scene has not matched any known suspects.

JonBenét was reported missing from her family’s home in Boulder on December 26, 1996. Her subsequent discovery in the basement less than a day later shocked the nation. Autopsy results classified her cause of death as strangulation, and since then, authorities have received over 21,000 tips and conducted numerous interviews across 19 states, but the case remains unsolved.

As efforts to generate new leads continue, Boulder police are urging any individuals with information related to the case to contact their tipline at 303-441-1974 or via email. The hope remains that with persistent investigation and technological advancements, justice may still be served in this enduring mystery.
