A former Colorado Bureau of Investigation forensic analyst was sentenced to 10 years in prison Tuesday for manipulating DNA data — but the real scandal is that the system let her cook evidence for roughly a decade while red flags piled up and bureaucrats looked the other way.

Yvonne "Missy" Woods pleaded guilty in June to perjury, attempting to influence a public servant, forgery, and a cybercrime. Dozens of additional counts were dropped under her plea deal. She faced between 8 and 16 years; the judge gave her 10. But the damage done to the people she helped convict — and to public trust in forensic science — may take far longer to sort out.

Woods' misconduct touched cases involving homicide, sexual assault, and robbery. Prosecutors have been forced to review hundreds of convictions. At least one murder conviction has already been overturned: Michael Clark walked out of prison in 2025 after his lawyers proved Woods mishandled the DNA evidence in his case. Prosecutors now say they'll try him again. In two other homicide cases, defendants got reduced sentences through plea deals because prosecutors feared Woods' involvement would sink their chances at trial — an implicit admission that her lab work was radioactive even before the public knew.

According to an arrest affidavit, Woods told investigators she altered data to complete cases more quickly. She altered data to conceal tampering, deleted data showing she failed to troubleshoot problems, and skipped documenting tests in case records.

At sentencing, Woods offered remorse. "For many years I was entrusted with evidence that could have profound consequences for defendants, victims, families and the courts. I failed that responsibility. I am deeply sorry for that failure," she said, as reported by the Denver Post.

Here's what the outlets covering this sentence all agree on but none want to dwell on: the system caught Woods years ago — and then let her keep working. A 2024 CBI internal affairs report revealed that concerns about her work first surfaced more than a decade ago. As early as 2014, a coworker questioned her evidence testing. In 2018, she was temporarily removed from DNA cases after being accused of data manipulation. She was quietly allowed back. The investigation that finally took her down didn't start until September 2023 — and it wasn't launched by a supervisor, an auditor, or any of the vaunted oversight mechanisms. An intern found missing information in a case file.

NBC News included a telling quote from CBI Director Armando Saldate after the sentencing: "The actions of one individual never define this organization, and they do not define the dedicated public servants who continued showing up every day with integrity." That's the institutional line — one bad apple, not a culture that ignored a decade of warnings. The Guardian and the Associated Press both omitted Saldate's remark entirely, sparing the bureau the embarrassment of having its deflection on the record.

The cleanup will cost Colorado taxpayers more than $11 million, according to state officials.

Woods resigned in 2023 after a decades-long career. The question nobody in authority wants to answer: how many people did she help lock away during the years the bureaucracy knew — or should have known — she was cutting corners and fabricating results? And how many forensic analysts across the country are doing the same thing right now, shielded by the same complacent institutions?
