BOSTON (AP) —
A chemist accused of lying about drug samples she tested at a state lab could face additional charges as prosecutors and defense attorneys sift through thousands of criminal cases that could be upended by her actions.
Annie Dookhan, 34, of Franklin, was arrested Friday in a burgeoning investigation that has already led to the shutdown of the lab, the resignation of the state's public health commissioner and the release of more than a dozen drug defendants.
Dookhan faces more than 20 years in prison on charges of obstruction of justice and falsely pretending to hold a degree from a college or university. She testified under oath that she holds a master's degree in chemistry from the University of Massachusetts, but school officials say they have no record of her receiving an advanced degree or taking graduate courses there.
State police say Dookhan tested more than 60,000 drug samples involving 34,000 defendants during her nine years at the Hinton State Laboratory Institute in Boston. Defense lawyers and prosecutors are scrambling to figure out how to deal with the fallout.
Verner said Dookhan later acknowledged to state police that she sometimes would take 15 to 25 samples and instead of testing them all, she would test only five of them, then list them all as positive. She said that sometimes, if a sample tested negative,
she would take known cocaine from another sample and add it to the negative sample to make it test positive for cocaine, Verner said.
Co-workers began expressing concern about Dookhan's work habits several years ago, but her supervisors allowed her to continue working. Dookhan was the most productive chemist in the lab, routinely testing more than 500 samples a month, while others tested 50 to 150.
One co-worker told state police he never saw Dookhan in front of a microscope. A lab employee saw Dookhan weighing drug samples without doing a balance check on her scale.
In an interview with state police late last month, Dookhan acknowledged faking test results for two to three years. She told police she identified some drug samples as narcotics simply by looking at them instead of testing them, a process known as dry labbing. She also said she forged the initials of colleagues and deliberately turned a negative sample into a positive for narcotics a few times.
