In this month’s D Magazine, I talked to Dr. Chris Nulf, a former Dallas County Crime Lab scientist who says the lab is mismanaged and uses expired chemicals to processes forensic kits. It’s not a strictly feminist piece, but in manner of the DA’s conviction integrity unit, anything that goes wrong at the lab could seriously impact rape convictions:
Nulf says the lab practices poor quality control, training is sloppy, and management retaliates against employees who raise concerns. If Nulf is right and there are serious problems with the crime lab, every case that relies on physical evidence could be called into question. Imagine if every convicted rapist going back five years suddenly had a good reason to appeal his case. Similarly, sloppy lab work could send innocent people to jail.
“People’s liberties are at stake here,” Nulf says.
