A former forensic analyst for the Colorado Bureau of Investigation has been sentenced to a decade in state prison after pleading guilty to manipulating DNA records in a major forensic scandal that compromised more than 1,000 criminal cases across Colorado. Yvonne "Missy" Woods received the 10-year prison sentence following a sweeping review of her nearly 30-year career at the state crime laboratory, bringing formal legal closure to a breach that severely impacted the state's criminal justice system.
The sentencing, handed down on Sept. 8, requires Woods to serve 10 years in the Colorado Department of Corrections, which will be followed by a mandatory three-year term of parole. The court's judgment finalized a criminal case that escalated after Woods entered a guilty plea in June to four felony offenses related to the systematic mishandling, alteration, and deletion of laboratory testing data.
Under the terms established in her negotiated plea agreement, Woods admitted guilt to four specific felony charges: perjury, attempting to influence a public servant, forgery, and cybercrime. The agreement set a sentencing parameter calling for a prison term between eight and 16 years. In exchange for her admission of guilt on those four counts, prosecutors agreed to dismiss the remainder of the more than 100 criminal charges originally brought against her.
Following the sentencing hearing, CBI Director Armando Saldate addressed the broader implications of the case, emphasizing accountability while underscoring the ongoing institutional recovery of the agency. Saldate noted in a public statement that although the sentence cannot undo the extensive harm caused by the analyst's misconduct, the conclusion of the case marks an essential step forward for the bureau and the public.
Saldate also affirmed that the rogue conduct of a single analyst should not overshadow the integrity of the state's broader forensic workforce. He maintained that Woods' criminal actions do not define the dedicated public servants who consistently execute their duties with integrity, adding that he remains proud of the substantial laboratory reforms and safeguards implemented by the CBI to ensure that crime victims throughout Colorado receive accurate and dependable answers.
In an official news release issued on Sept. 8, CBI leadership described the sentencing as a vital milestone in closing an extraordinarily difficult chapter for the bureau, crime victims, affected families, prosecutors, defense attorneys, law enforcement agencies, and local communities. Agency officials characterized Woods' actions as both a criminal violation of the law and a profound betrayal of the core scientific standards and professional ethics that govern the CBI and its forensic facilities.
The extensive pattern of data manipulation was first uncovered in September 2023 when an intern working on a research project identified critical anomalies in Woods' documentation. That initial discovery immediately triggered an internal CBI inquiry into the analyst's testing procedures and analytical records.
Upon opening the internal review, the CBI quickly uncovered deeper discrepancies within Woods' laboratory workbooks. According to findings detailed by the First Judicial District Attorney's Office, these irregularities included altering and deleting critical scientific data directly tied to crucial phases of the laboratory's quality control processes.
To ensure an independent and impartial investigation into the missing and manipulated data, the CBI requested the assistance of an outside agency. In November 2023, the South Dakota Division of Criminal Investigation launched a full criminal investigation into the analytical anomalies and missing records at the Colorado laboratory.
The extensive multi-agency investigation led to formal prosecution in January 2025, when the First Judicial District Attorney's Office charged Woods with 102 separate criminal offenses. A comprehensive retrospective review conducted across Woods' nearly 30-year career ultimately established that a total of 1,045 criminal cases had been impacted by her compromised forensic analysis.
The repercussions of the tainted testing extended across multiple jurisdictions in Colorado, including Pueblo County. In 2024, while the investigation was still developing, former 10th Judicial District Attorney Jeff Chostner confirmed that at least one local case had been affected by Woods' casework, though specific details could not be disclosed publicly because the case involved a juvenile.
During the earlier phases of the inquiry, state officials had initially confirmed 600 affected cases before broader reviews uncovered more than 400 additional compromised files, bringing the final tally past 1,000. It remains unclear whether any of those additional 400-plus cases originated in Pueblo, as 10th Judicial District Attorney Kala Beauvais declined to provide further details or comment when contacted in June.
In the wake of the scandal, the CBI commissioned an independent external review to evaluate its forensic operations. The resulting Forward Resolutions Audit and Assessment Report confirmed that the bureau's forensic laboratories are operating in accordance with national best practices and verified that the agency has made substantial progress in strengthening its internal systems, oversight mechanisms, and organizational culture.
CBI officials emphasized that the bureau has actively enacted the audit's findings and recommendations through aggressive structural reforms. Agency leaders stated that these ongoing measures are designed to reinforce public trust and provide full confidence to victims, the judicial system, and the broader public safety community that the state's forensic laboratories produce accurate, reliable, and scientifically sound results.
