Problems in San Diego crime lab come to light in audits and internal documents
Testimony at the Jane Dorotik hearing has revealed long-running concerns inside the county crime lab about the work record of a former criminalist
But some of its work over the years has become pivotal in the ongoing case of Jane Dorotik, a former Valley Center woman who was convicted in 2001 of murdering her husband, Robert. Much of the evidence in that case relied on the lab’s work on bloodstains, crime scene reconstruction and DNA.
In its response at the time, lab officials said they would discuss the reports that contained errors with both the analysts and reviewers, issue amended reports if necessary, and hold a general meeting to go over the technical review process. Suzanna Ryan, a DNA expert and forensics consultant based in Carlsbad, said sample-switch incidents were a concern. “That’s one of the most serious errors in a lab,” she said. Even though no common cause could be determined and they happened nearly a decade ago, the errors signaled a problem.Botched testing errors predated the sample switches reviewed by Hassler.
Audits that discover problems are not unusual, Ryan said. “Any lab you look at, you are going to find errors,” she said. “Most of the time they are errors that are minor or a one-time occurrence. You try to avoid them.”But Brandon Garrett, director of the Wilson Center for Science and Justice at Duke University School of Law, said “labs are supposed to have quality controls in place to make sure they don’t make mistakes.
