Colorado DNA Scientist Accused of Manipulating Data, Affecting Over 1,000 Cases

An internal investigation reveals Yvonne “Missy” Woods tampered with DNA results, prompting a review of nearly three decades of her work.

Over 1,000 Colorado criminal cases are now in question after DNA scientist Yvonne “Missy” Woods was accused of manipulating data in her work at the Colorado Bureau of Investigation.
The internal investigation found Woods deviated from standard protocols and tampered with DNA results, affecting cases between 2008 and 2023. A review of her work from 1994 to 2008 is also underway.
Woods' manipulation of DNA data has led to a review and retesting of an estimated 3,000 DNA samples by an independent third-party laboratory, with the state agency requesting an additional $7.5 million for this purpose.
A federal lawsuit claims a man was wrongly convicted based on Woods' work, raising concerns about potential false convictions and unjust imprisonments.
Public trust is emphasized as critical, with CBI Director Chris Schaefer stating that actions to rectify the breach of trust will be thorough and transparent.
