The chemist who is accused of tampering with evidence in 34,000 state drug criminal cases will be in court today.

Annie Dookhan was indicted Monday on 27 charges related to evidence tampering while she was a chemist at the now shut down Hinton Drug Lab in Jamaica Plain. 

She will appear in Suffolk Superior Court at 9:30 a.m.

The statewide grand jury indictment included 17 counts of obstruction of justice, eight counts of tampering with evidence, perjury and falsely pretending to hold a degree from a college or university, according to a press statement from Attorney General Martha Coakley's office.

Authorities allege that Dookhan obstructed justice by falsely certifying drug analyses, or causing others to do so, when she knew the results were compromised as a result of her “dry labbing” and tampering with evidence vials, according to the statement.

Several of those convicted on drug charges have been freed as direct result of Dookhan's mishandling of evidence in their cases.

The Hinton Drug Lab, located in Jamaica Plain, was not accredited and had a poor history of oversight.
