Golden, Colorado (AP) " A judge sentenced a former forensic analyst for the Colorado Bureau of Investigation to 10 years in prison on Tuesday after authorities said her manipulation of DNA data raised questions about the validity of hundreds of criminal cases. Yvonne "Missy" Woods pleaded guilty in June to perjury, attempting to influence a public servant, forgery and committing a cybercrime. Dozens of other counts were dismissed as part of a plea agreement. Problems with the scientist's work were found in cases involving homicide, sexual assault, robbery and other crimes, according to authorities. Prosecutors were forced to review hundreds of cases, and at least one murder conviction was vacated as a result of Woods' misconduct.
