Scary Crime Lab News

The ABA Journal just published a chilling article about shoddy and incompetent crime labs. Shockingly, the reports detailed in the article relate to some of the most supposedly sophisticated and civilized corners of the country, including New York City, Boston, and Minneapolis.  Here are some highlights of the article:

In January, the New York City medical examiner’s office confirmed that it was reviewing more than 800 rape cases from a 10-year period during which DNA evidence may have been mishandled by a lab technician who resigned in 2011 after an internal review uncovered problems with her work.

The review, then about half complete, had already turned up 26 cases in which the former technician failed to detect the presence of DNA evidence, including one in which the evidence has since led to an arrest in a 10-year-old rape case. The review uncovered 19 cases in which DNA evidence was commingled with DNA evidence from other cases.

[T]he St. Paul, Minn., police department’s crime lab suspended its drug analysis and fingerprint examination operations after two assistant public defenders raised serious concerns about the reliability of its testing practices. A subsequent review by two independent consultants identified major flaws in nearly every aspect of the lab’s operation, including dirty equipment, a lack of standard operating procedures, faulty testing techniques, illegible reports, and a woeful ignorance of basic scientific principles.

Assistant public defender Lauri Traub stumbled onto the lab’s problems when she asked to meet with the analyst who tested suspected drugs one of her clients was accused of possessing. Traub says she was horrified by what she found: The lab, an old-fashioned “cop shop,” was run by a police sergeant with no scientific background, had no written operating procedures, didn’t clean instruments between testing, allowed technicians unlimited access to the drug vault, and didn’t have anyone checking anyone else’s work. Analysts didn’t know what a validity study was, used Wikipedia as a technical reference, and in their lab reports referred to “white junk” clogging an instrument.
