New allegations threaten DUI cases in San Francisco

SAN FRANCISCO

According to the San Francisco Chronicle, a supervising toxicologist vouched for the reliability of alcohol detection equipment in blood test results in DUI cases for two years in a Washington State lab. She signed off on the cases even though she had not tested the equipment herself.

Prosecutors told defense attorneys she had been accused of fraud in that state. Anne Marie Gordon was hired in San Francisco in 2008. Before that, she ran Washington's toxicology lab.

Hundreds of criminal convictions in San Francisco are already at risk because prosecutors withheld police officers' criminal histories or misconduct records from defense attorneys.
