This article didn't state what has caused this issue to surface after 29 years of accepting her work as the gold standard, at least that I saw. All it seemed to talk about were some of the cases she was involved in.

“Colorado launches criminal probe into its star forensic analyst Yvonne ‘Missy’ Woods who ‘performed shoddy DNA testing and altered data that sent HUNDREDS of people to jail over her three-decade career”
This is devastatingly huge. Past testing has to be retested. Everything she’s ever done in a lab regarding forensics. Wow.
