JonBenét DNA Analyst Sent to Prison

A former Colorado DNA analyst whose misconduct shook confidence in hundreds of criminal investigations has been sentenced to 10 years in prison. But claims tying her crimes to the unsolved murder of JonBenét Ramsey leave out a crucial finding from authorities.

Yvonne “Missy” Woods, 66, received the sentence September 8 after pleading guilty to cybercrime, first-degree perjury, attempting to influence a public servant and forgery, according to the Colorado First Judicial District Attorney’s Office.

Her punishment follows a scandal involving altered and deleted laboratory data, false reports and renewed questions about cases that depended on her work.

For those following JonBenét’s murder, however, there is an important distinction. Boulder police and prosecutors told Fox News Digital that a CBI review found Woods’ misconduct had not affected the Ramsey evidence.

That finding undercuts suggestions that Woods’ prison sentence represents a breakthrough in the little girl’s case.

Woods worked for the Colorado Bureau of Investigation from January 1994 until November 2023, meaning she was employed there when JonBenét was killed. But employment at the agency does not establish that she mishandled evidence in that investigation.

The criminal conduct covered by her guilty plea occurred between 2008 and 2023, according to prosecutors. She entered the plea June 23 under an agreement requiring between eight and 16 years behind bars.

The investigation began after a CBI intern discovered missing data in a sample Woods had processed years earlier. Prosecutors ultimately identified 53 cases involving false or misleading reports, while alterations to laboratory notes affected hundreds more.

In many of the charged incidents, Woods reported that DNA was absent when testing had detected it. Prosecutors said that stopped some investigations before scientists could proceed to identifying or comparing the DNA.

The criminal investigation did not establish that she created false DNA identifications or false positive results—a distinction that does not erase the damage caused by concealing evidence.

“I failed that responsibility,” Woods said at sentencing, acknowledging the consequences for defendants, victims and families. A restitution hearing is scheduled for November 12.

One case drawn into the fallout involved Michael Clark, who was convicted in 2012 of killing Marty Grisham in Boulder in 1994.

According to Denver7 reporting published by KOAA, Clark’s conviction was overturned and he was released in April 2025. As of the September sentencing coverage, he was awaiting a retrial, with proceedings paused over evidence-disclosure issues. CBI has said Woods’ misconduct did not affect the DNA testing in his case.

Clark’s attorney, Adam Frank, separately sought early investigative records from the Ramsey case, arguing they could support claims about mistakes in Boulder police investigations. That request was denied. It did not establish that Woods tampered with JonBenét evidence.

Meanwhile, John Ramsey continues to press for additional testing in his daughter’s case.

“I believe getting the crime scene evidence into the hand of an outside DNA lab is step one,” he told RadarOnline.

His frustration is longstanding, but police dispute suggestions that they are ignoring forensic opportunities. On their official case page, investigators describe working with the FBI, CBI and outside forensic laboratories.

In the department’s December 2025 video update, Police Chief Stephen Redfearn said detectives had conducted new interviews, collected additional evidence and tested or retested other items to pursue fresh leads. Authorities have not publicly detailed all ongoing testing.

JonBenét was 6 when she was reported missing from her family’s Boulder home on December 26, 1996. She was found dead inside the house later that day.

Nearly 30 years later, the investigation remains open. Woods’ conviction establishes serious wrongdoing in Colorado’s forensic system, but it does not identify JonBenét’s killer or establish that her evidence was compromised.
