Former Colorado Crime Analyst Sentenced to 10 Years in Prison in DNA Testing Scandal
Woods admitted to four felonies after investigators found she altered DNA data in 1,045 cases and triggered reviews of hundreds of convictions.
On Tuesday, Jefferson County District Judge Andrew Poland sentenced former Colorado Bureau of Investigation forensic scientist Yvonne "Missy" Woods to 10 years in prison for her role in a DNA testing scandal.
Woods pleaded guilty to four felonies, including cybercrime and forgery, after admitting she manipulated DNA data to speed up processing during her 29-year career at the agency.
Prosecutors described a pattern of deception spanning more than 100 cases; the investigation revealed Woods mishandled at least 1,045 criminal cases, costing the state an estimated $11 million to retest evidence.
Convictions were dismissed in cases including a 1994 Boulder murder, while prosecutors offered reduced sentences in other murder cases to avoid relying on tainted DNA evidence.
Lawmakers passed legislation in 2025 to increase forensic testing oversight, yet post-conviction challenges continue across Colorado as officials warn the uncertainty caused by Woods' actions will linger for years.
