The husband of the former Massachusetts chemist charged with faking test results at a state drug lab warned a prosecutor that his wife was a habitual liar years before she was caught.

In state police documents obtained by The Boston Globe, former assistant Norfolk District Attorney George Papachristos told police that Surren Dookhan contacted him in August 2009 after he befriended Annie Dookhan.

According to the documents, Surren Dookhan texted to the prosecutor in August 2009 that his wife was “always lying” and looking for “sympathy and attention.”

Annie Dookhan has pleaded not guilty to 27 counts of obstructing justice and altering drug evidence, casting doubt on thousands of criminal cases. She is scheduled to be in court Wednesday.

Her husband has not spoken publicly about the case.
