BOSTON (December 20, 2012)—Annie Dookhan, the former chemist at the center of a drug testing scandal at a now-closed Massachusetts lab, pleaded not guilty Thursday to charges including perjury and tampering with evidence.
Dookhan was arraigned Thursday in Suffolk Superior Court.
Neither she nor her attorney commented after the proceeding.
Attorney General Martha Coakley alleges that Dookhan fabricated test results and tampered with drug evidence in testing substances for criminal cases. Judges have released about 200 defendants from prison in the last few months and put their cases on hold.
The state also is reviewing thousands of cases possibly affected by Dookhan's work.
Dookhan was indicted this week on numerous counts.
First arrested in September, she remains free on bond, but has a curfew.
The judge Thursday extended the hour to 10 p.m.
