A former Colorado Bureau of Investigation DNA scientist appeared in court to face criminal charges related to data tampering that has raised concerns about the validity of over 500 cases. The scientist, Yvonne “Missy” Woods, allegedly tampered with evidence in cases involving homicide, sexual assault, robbery, and other crimes.
Authorities discovered issues with Woods' work, leading to questions about the accuracy of the cases she was involved in. In some instances, defendants received reduced sentences through plea deals due to concerns about Woods' involvement potentially leading to acquittals.
Woods, described as a 'star analyst' by a former colleague, faced allegations of working too quickly and lacking thoroughness in her analysis. The investigation into Woods' misconduct began in 2023 after missing information was discovered in a case she handled in 2018.
Woods faces multiple charges, including forgery, attempting to influence a public servant, perjury, and cybercrime, for alleged misconduct spanning from 2008 to 2023. The fallout from her actions has impacted numerous criminal investigations, with prosecutors across the state reviewing affected cases.
One recent case involved Michael Shannel Jefferson, who was sentenced to 32 years in prison for a 1985 home invasion killing. Due to the allegations against Woods, Jefferson accepted a plea deal for a lesser charge, maintaining his innocence despite the plea.
The investigation revealed that Woods altered data, deleted information, and failed to document tests properly, leading to concerns about the integrity of the cases she worked on. The response to Woods' alleged misconduct has incurred significant costs, with state officials estimating expenses exceeding $11 million.
State authorities have taken steps to address the situation, including requesting funds for retesting DNA samples and hiring a consulting firm to review the forensic program. The case highlights the importance of upholding scientific integrity and accountability within the criminal justice system.
