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.
