Colorado DNA Scandal: Thousands of Cases in Jeopardy

A forensic scientist's misconduct prompts a massive review of criminal cases, raising concerns over wrongful convictions.

For nearly three decades, Yvonne “Missy” Woods was considered a gold standard in forensic DNA testing in Colorado, contributing to the conviction of numerous criminals.
Woods abruptly resigned in November after an internal review discovered anomalies in her work, leading to a criminal probe and a review of approximately 3,000 DNA samples she handled.
Investigators found Woods manipulated data and cut corners in at least 650 cases, raising questions about the integrity of her work and the potential for wrongful convictions.
State lawmakers have allocated nearly $7.5 million for possible retrials, case reviews, and the retesting of DNA samples affected by Woods's misconduct.
The scandal has prompted a comprehensive audit of all DNA analysts at the Colorado Bureau of Investigation and has led to the firing of another DNA analyst in Weld County for similar misconduct.
