Aformer forensic scientist intentionally manipulated DNA evidence during her 29-year career at the Colorado Bureau of Investigation, casting doubt on at least 652 criminal cases she handled, including some of the most high-profile trials, according to investigation findings released by the agency Friday.
That number could grow as outside investigators continue to review DNA testing done by Yvonne “Missy” Woods, after a probe revealed she manipulated data in the testing process and in some cases, posted incomplete test results, in the cases she handled between 2008 and 2023.
The discovery is putting all of Woods’ work into question and CBI is also looking at her work dating to 1994, when she started working for CBI. The agency launched the investigation in September after anomalies were discovered in her work.
