Former San Francisco police drug lab technician Deborah Madden refused to testify in San Francisco California DUI trial-suspected of stealing evidence

The California DUI jury hung recently in a drunk driving case in which nationally recognized DUI expert Mary McMurray testified.

This DUI case became popular when disgraced former San Francisco police drug lab technician Deborah Madden refused to testify.

The trial's inconclusive outcome may not bode well for San Francisco DUI Attorney prosecutors, still struggling to salvage drug and DUI cases involving Madden, who left the city's crime lab in December amid suspicions that she stole drug evidence and has since retired.

The accused in this DUI trial, Mr. Thomas, was pulled over by San Francisco DUI police in May 2008 for having a broken windshield. He allegedly did not pass a California DUI sobriety test.

Mr. Thomas went on the lam, was later arrested in another county and has spent the last few months locked up in the city, unable to make $50,000 bail on the misdemeanor California DUI charge.

Madden was the last to conduct a routine check on the California DUI breath alcohol-testing machine that police used when they arrested Thomas. DUI Lawyer Prosecutors claim the estimator showed his blood alcohol level was 0.11%.

Madden was assigned the job of testing the equipment, which she first found had problems but later claimed was in proper working order.

Thomas' California criminal defense lawyer attacked Madden, saying she was just part of larger problems at the crime lab. Madden took the Fifth Amendment, leaving her ex-boss, Lois Woodworth, to testify that the equipment was just fine.

At least three jurors didn't buy it, while nine voted to convict. The panel hung last month, and the case is due back in court for a possible retrial.

McMurray traveled from Wisconsin to assist in exposing this crime lab.
