Colorado, Sep 9: A former forensic analyst with the Colorado Bureau of Investigation has been sentenced to 10 years in prison after authorities found that her manipulation of DNA data had raised questions over the validity of hundreds of criminal cases.
Yvonne “Missy” Woods was sentenced on Tuesday after pleading guilty in June to charges including perjury, attempting to influence a public servant, forgery and committing a cybercrime. Several other charges against her were dismissed as part of a plea agreement.

Authorities said irregularities were discovered in Woods' work in cases involving murder, sexual assault, robbery and other serious crimes. Prosecutors were subsequently forced to review hundreds of cases, while at least one murder conviction was vacated following revelations about her misconduct.
Woods, who resigned from the bureau in 2023 after a decades-long career, was accused of altering and deleting data to conceal problems in the DNA testing process and failing to properly document tests carried out in case records.
During the sentencing hearing, Woods apologised for her actions and admitted that her words could not undo the damage caused.
“For many years I was entrusted with evidence that could have profound consequences for defendants, victims, families and the courts. I failed that responsibility,” she said.
The investigation into Woods began in September 2023 after an intern discovered missing information in a case she had handled in 2018. Investigators later alleged that Woods admitted to changing data in an effort to complete cases more quickly.
The fallout has already affected several criminal proceedings in Colorado. In one murder case, Michael Clark was released from prison in 2025 after his lawyers argued that DNA evidence had been mishandled. Prosecutors have said they intend to retry the case.
Concerns over Woods' work had reportedly surfaced years earlier. A 2024 internal affairs report found that questions had been raised about her testing procedures as early as 2014, while she was temporarily removed from DNA casework in 2018 following allegations of data manipulation.
Colorado Bureau of Investigation officials said they were undertaking reforms to strengthen laboratory procedures and restore public confidence. State officials have estimated that addressing the fallout from the scandal could cost more than $11 million.
