More Blood-Alcohol Test Errors Discovered At OC Crime Lab
SANTA ANA (CBSLA.com) — More blood-alcohol test errors have been discovered at Orange County’s crime lab.
KNX 1070’s Mike Landa reported that earlier this month, an audit at the Orange County Crime Lab found mistakes in alcohol readings involving hundreds of drunk driving cases.
Orange County sheriff’s Lt. Jeff Hallock said a second audit showed calibration errors involving 100 other cases.
“Of those 100 blood samples, there were nine samples that actually changed a reading from a 0.07 to 0.08. Obviously that 0.08 is a sign because that’s the threshold for the driving under the influence,” he said.
Hallock added, “In the last [audit], the blood-alcohols actually went down. In this case, the blood-alcohol levels are actually going up slightly.”
A state agency will audit the crime lab’s blood-alcohol equipment and procedures.
In addition, the latest errors will be reported to the Orange County district attorney’s office, according to Hallock.
