The Weld County district attorney’s office will not file charges against a former forensic scientist with the sheriff’s office over anomalies discovered in her DNA casework, officials announced Thursday.

Chiara Wuensch was fired from the sheriff’s office in March after abnormalities were discovered in her DNA casework during the Colorado Bureau of Investigation’s examination of the ongoing, multimillion-dollar problem surrounding Yvonne “Missy” Woods’ flawed lab results.

At the time, the sheriff’s office said it planned to pursue criminal charges against Wuensch over the problems with her work, but the district attorney said Thursday that was not the case.

“A review of Ms. Wuensch’s work revealed only five anomalies among thousands of DNA data entries,” District Attorney Michael Rourke stated in a news release.

The abnormalities fell into three categories: the alleged deletion of data indicating a small amount of male DNA, the alleged addition of the word “undetermined” to a cell in a spreadsheet and the alleged alteration of values related to potential contamination, according to the news release.

Wuensch denied intentionally altering or deleting data, attributing any discrepancies to potential mistakes in using Excel, the release stated.

“After a comprehensive review of all the evidence and circumstances, it is clear that the anomalies found in Ms. Wuensch’s work do not meet the legal threshold for criminal charges,” Rourke stated in the release. “The evidence does not support a finding of criminal intent, and therefore, it would be inappropriate to pursue charges in this matter.”

The district attorney’s office said the anomalies could be seen as intentional acts to avoid additional work and testing required by CBI’s standard procedures. However, there was no reason for Wuensch to change the data intentionally, as she still performed the extra DNA amplification required by those procedures, the office said.

CBI agreed, confirming the anomalies did not impact any DNA identification or elimination in criminal cases, the release stated.
