Annie Dookhan pleads not guilty to charges in drug lab scandal

Former state chemist ­Annie Dookhan pleaded not guilty in Suffolk Superior Court Thursday to 15 charges of allegedly mishandling and tainting drug evidence, includ­ing one case in which she claimed to have tested a drug sample that was not even in her laboratory at the time.

Dookhan, 35, is at the center of one of the largest law enforcement scandals in ­recent state history and her actions in the now-closed state drug laboratory in Jamaica Plain may affect tens of thousands of cases and cost taxpayers millions of dollars.
