“State investigators have found at least a half-dozen drug samples scattered about the state lab in Jamaica Plain, documents show, raising questions about the integrity of all testing where indicted state chemist Annie Dookhan worked. Investigators found a plastic bag containing ‘a white rock substance’ and test tubes ‘containing unknown substances’ in one supervisor’s office. They found pills taped to a lab bench cabinet and old samples, including marijuana submitted in 1996. The findings, in a confidential report by the attorney general, add fuel to defense lawyers’ arguments that virtually all drug tests done there since 2003 are suspect.”
