CLAYTON, Mo. (KMOX)-A veteran St. Louis County crime lab scientist has resigned, after failing to fully test evidence in more than a half-dozen drug cases.
Crime Lab Commander, Lt. Mason Keller, says the seven cases all involved marijuana and all occurred in September.
The woman, who had worked at the lab over 20 years, reportedly said that she was too overworked to properly complete the tests. Keller says that hasn’t
been confirmed, “That’s a comment she had made to either one of the supervisors here or during the investigation. That doesn’t necessarily mean that’s what the case was.”
Keller says one of the scientist’s co-workers informed supervisors of her failing to follow protocol.
He says each of the seven cases have been checked again, “Those cases were each retested as though they were a brand new case and reported on using our normal lab procedure. All the findings were exactly the same. They actually came back as positive for marijuana.”
The scientist’s name is not being released while the internal investigation continues.
