A state judge in Golden, Colorado, sentenced Yvonne “Missy” Woods, a former forensic analyst for the Colorado Bureau of Investigation (CBI), to 10 years in prison on Tuesday for manipulating DNA data in criminal cases.
Woods, who resigned in 2023 after a decades-long career, pleaded guilty in June to perjury, attempting to influence a public servant, forgery, and committing a cybercrime. Dozens of additional counts were dismissed as part of a plea agreement. Prosecutors stated her misconduct raised concerns about the validity of hundreds of criminal cases, including those involving homicide, sexual assault, and robbery.
At least one murder conviction was vacated as a result of her actions, and authorities were forced to review hundreds of cases linked to her work.
Core Findings and Legal Consequences
Woods faced a sentencing range of 8 to 16 years before District Judge Andrew Poland imposed the 10-year term. During her sentencing hearing, she apologized for her actions, acknowledging the harm caused to defendants, victims, families, and the courts.
“For many years I was entrusted with evidence that could have profound consequences for defendants, victims, families and the courts,” Woods said. “I failed that responsibility. I am deeply sorry for that failure.”
Scope of Misconduct and Investigative Details
Authorities accused Woods of altering data to conceal tampering, including deleting information that showed she failed to troubleshoot testing issues and omitting thorough documentation of tests performed in case records. An investigation into her conduct began in September 2023 after an intern at the CBI discovered missing information in a case Woods handled in 2018.
According to an arrest affidavit, Woods allegedly told investigators she had changed data to complete cases more quickly. Her actions prompted a review of hundreds of cases, with prosecutors confirming that her misconduct directly impacted at least one overturned murder conviction.
Response and Reforms by the Colorado Bureau of Investigation
Following the sentencing, CBI Director Armando Saldate issued a statement emphasizing that Woods’ actions did not reflect the broader organization.
“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,” Saldate said. He added that the bureau has sought to reform its laboratories in response to the scandal to rebuild public trust.
The case has drawn attention to the integrity of forensic evidence and the accountability measures within state crime laboratories. Officials have not disclosed the full extent of cases affected by Woods’ misconduct, though investigations remain ongoing.
