GOLDEN, Colo. (AP) — A former forensic analyst with the Colorado Bureau of Investigation pleaded guilty Tuesday to four felony counts stemming from accusations that she manipulated and omitted data to speed up the DNA testing process, calling into question the validity of hundreds of criminal cases. Yvonne “Missy” Woods entered guilty pleas to committing a cybercrime, perjury, attempting to influence a public servant and forgery. Dozens of other counts were dismissed as part of a plea agreement. Woods was set to stand trial later this year. Instead, she’ll face between 8 and 16 years in prison when she’s sentenced in September.Woods and her attorneys declined to talk to reporters after Tuesday’s hearing.Authorities accused Woods, who resigned in 2023 after a decades-long career, of altering data to conceal tampering, deleting data that showed she failed to troubleshoot issues within the testing process and not thoroughly documenting tests performed in case records.

The investigation into Woods’ misconduct began in September 2023 after an intern at the bureau discovered missing information in a case that Woods handled in 2018. According to an arrest affidavit, Woods allegedly told investigators at one point that she had changed data to complete cases more quickly.
