Jill Spriggs is showing off her highly trained staff and the expensive equipment they use to dissect evidence from crime scenes and help solve cases.
The highest-profile part of Sacramento County’s forensic sciences laboratory, however, is off limits. It’s where criminalists create DNA profiles – and where every precaution is taken to prevent contamination. The afternoon Spriggs gave a tour, Nikki Sewell was trying to extract DNA from a jacket in a robbery case and Angel Shaw was processing a rape kit. In another lab, Leslie Poole was hoping to match bullet cartridges from a series of shootings after swabbing a gun for DNA.
