The forensic analyst at the center of Colorado’s DNA scandal is going to prison, the sharpest turn yet in a case that has shadowed the unsolved 1996 killing of six-year-old JonBenét Ramsey. A judge handed down a sentence of 10 years in prison on September 8, 2026, to Yvonne “Missy” Woods, the former Colorado Bureau of Investigation (CBI) forensic DNA analyst whose manipulation of evidence sent prosecutors statewide back into closed files.
Under the plea agreement Woods, 66, reached in June, she had faced eight to 16 years. She admitted to four felonies: cybercrime, perjury, forgery and attempting to influence a public servant. The judge ordered her sentences on the other three counts to run concurrently and added three years of mandatory parole. The deal dismissed 100 additional charges.
Woods spent nearly three decades at the CBI, and her career ended with her retiring in 2023 after being placed on administrative leave. Prosecutors say she falsified DNA results and pulled forensic records out of criminal files dating back to 2008; as many as 1,045 cases were alleged to have been touched by her conduct. Her career caseload is put by authorities at more than 10,000, with problems surfacing in roughly 10 percent of them. Woods had “accepted responsibility not only for individual acts of misconduct but for the full scope of criminal conduct that spanned decades,” District Attorney Alexis King said.
Fallout Across Colorado Cases
Denver police have said they reopened 13 closed sexual-assault cases after retesting DNA evidence tied to Woods’ work. Eleven of those retests yielded profiles eligible for CODIS. Another six pointed to possible investigative leads.
One conviction has already collapsed. Michael Clark was more than 12 years into his time behind bars when a judge vacated his conviction in April 2025 in the 1994 fatal shooting of Marty Grisham in Boulder, because Woods had played a role in his 2012 trial. Adam Frank, his defense attorney, went on to seek access to the Boulder police files covering the first 48 hours of the Ramsey investigation, his argument being that both cases had been derailed by the same sorts of investigative errors. That request was denied by a judge in October 2025.
What the Boulder Review Found
Their review found no effect on evidence in the Ramsey investigation, Boulder police and the Boulder County District Attorney’s Office say. JonBenét was killed in 1996, while Woods’ documented criminal conduct runs from 2008 to 2023. Her employment at the CBI did overlap with that original investigation, but whether she personally handled evidence in the case is something authorities have not said. John Ramsey, JonBenét’s father, has said an outside laboratory, rather than the state agency, received the key DNA evidence in the case.
That amounts to insulation of a sort from the fallout now reshaping other Colorado prosecutions.
New Technology, Old Evidence
Investigators in Boulder say they are revisiting the evidence to learn what newer forensic methods might produce, and independent outside laboratories are being considered for advanced DNA testing. Detectives have carried out fresh interviews, gone back to people on the strength of tips, collected new evidence, and tested and retested other items in search of leads, according to the Boulder Police Department. The Colorado Cold Case Review team is also being consulted by the department.
Police concede that critical mistakes marked the initial response — no one secured the crime scene, and formal interviews with JonBenét’s parents were delayed — yet they maintain the case can still be solved. The Cold Case Review Panel was convened by Boulder police rather than the CBI, and the department’s partners include the FBI, the district attorney’s office, Colorado’s Department of Public Safety, the CBI and several outside forensic labs.
A Father Still Pressing for Answers
The sentencing landed in the middle of an argument John Ramsey, JonBenét’s 82-year-old father, has pressed for years. He told RadarOnline, “The police are not going to solve this the way they are doing it.” He added, “I believe getting the crime scene evidence into the hand of an outside DNA lab is step one.”
To Ramsey, there is no mystery about who killed his daughter; no one has ever put a name to the man. Investigators did recover unidentified male DNA from JonBenét’s underwear and long johns, and that profile has never been matched to a suspect. Forensic genetic genealogy — a technique that traces biological relatives through genealogical databases — is the approach Ramsey has urged investigators to adopt, and he has volunteered to help raise money for the testing. Rather than rely on conventional state resources, he wants Boulder to hire a specialized private laboratory.
Some physical evidence from the scene was sent for laboratory analysis while other items were left untested, Ramsey has said, and the family questioned that selective approach. The Boulder police chief told him more items from the scene would go out for testing, he has said, and no update on the results ever reached the family. Days before Woods entered her guilty plea, on June 19, he appeared at a crime event in Royal Oak, Michigan.
Six-year-old JonBenét Ramsey was reported missing from the family’s Boulder house on the 700 block of 15th Street on December 26, 1996. The basement of the house is where her body was found, and an autopsy gave the cause of death as strangulation. Detectives have chased more than 21,016 tips, letters and emails in the years since, and 19 states have been visited to interview more than 1,000 people. Nearly 30 years on, the case remains unsolved. Anyone with information is asked by Boulder police to call the tipline at 303-441-1974 or email BouldersMostWanted@bouldercolorado.gov.
