"Colorado DNA Scientist Manipulated Data in Hundreds of Cases, Investigation Finds"

A former forensic scientist at the Colorado Bureau of Investigation manipulated or omitted DNA test results in hundreds of cases over her nearly 30-year career, prompting a full review of her work. The internal investigation found that Yvonne “Missy” Woods' handling of DNA testing data affected 652 cases between 2008 and 2023, leading to a separate criminal investigation and a federal lawsuit alleging wrongful conviction. The agency is conducting a comprehensive audit of all DNA analysts to ensure the accuracy and completeness of its records, and a separate case of potential data manipulation by an analyst at the Weld County Sheriff’s Office has been discovered.
