The Wall Street Journal reports that the Colorado "star analyst" Missy Woods (in DNA analysis in criminal cases) has altered data.

The DNA Scandal That Threatens Thousands of Criminal Cases
Colorado investigators say star analyst Yvonne ‘Missy’ Woods altered data. Now people she helped send to prison want their convictions re-examined.

I'm pretty sure people will hit a paywall, but putting her name and state into a search engine will bring up more stories. Here's the introduction:

For nearly three decades, Yvonne “Missy” Woods was Colorado’s star forensic scientist, relied on by police and prosecutors to test DNA evidence in the state’s most baffling crimes.

Her work was considered the gold standard by colleagues and helped put away infamous murderers, including the “Colorado Hammer Killer.”

Then, in November, Woods abruptly resigned. The same day, the Colorado Bureau of Investigation said it had discovered anomalies in her work during an internal review and was launching a criminal probe.

The unfolding scandal—potentially one of the largest in the history of forensic DNA testing, according to experts—is throwing Colorado’s criminal justice system into chaos. The state said it would need to review and retest approximately 3,000 DNA samples that Woods handled. Public defenders estimate thousands of cases could be affected.

Prosecutors are bracing for numerous legal challenges from people charged or convicted based on Woods’s findings. State lawmakers recently allocated nearly $7.5 million for possible retrials and case reviews, along with the retesting.

At the center of the storm is a mystery: Was Woods just sloppy, or has she been purposefully cutting corners for decades to put people behind bars?
