Police arrested a Massachusetts forensic chemist on Sept. 28. Annie Dookhan allegedly tampered with drug evidence in criminal cases, forged colleagues’ signatures, and faked her academic credentials while working at a state crime lab. The unfolding investigation, which could upend thousands of narcotics convictions, has already led to the shutdown of the lab and the resignation of the state public health commissioner who oversaw it.
Dookhan, 34, was charged with obstructing justice by lying about the integrity of evidence, as well as about her academic qualifications. She is thought to have tested some 60,000 drug samples during her career at the William A. Hinton State Laboratory Institute, a state crime lab. “Annie Dookhan’s alleged actions corrupted the integrity of the entire criminal justice system,” Massachusetts Attorney General Martha Coakley said at a press conference.
According to a police report obtained by the Boston Globe, Dookhan told investigators that she forged coworkers’ initials on reports for mass spectrometer calibrations, intentionally contaminated samples, and engaged in “dry-labbing”—identifying narcotics by sight rather than by chemical analysis. In interviews with police, several colleagues said they’d expressed concern to supervisors about Dookhan’s unusually high productivity. Her résumé lists a master’s degree in chemistry from the University of Massachusetts, Boston, but she does not hold that credential according to school officials.
“This is a calamity,” says Justin J. McShane, a defense attorney in Harrisburg, Pa., who is closely watching the case. Because the evidence Dookhan allegedly mishandled was more than likely destroyed in the normal course of business, no traceable information exists to correctly characterize samples in thousands of drug cases, he explains.
“I don’t think this is going to end with a single chemist,” adds Edward P. Ryan Jr., former president of the Massachusetts Bar Association. Dookhan’s supervisors at best signed off on her work and at worst were complicit in her alleged crimes, he says. “This is an ever-expanding spiderweb, and I don’t know where the end is going to lie.”
Dookhan is an American Chemical Society member and a member of several ACS divisions, including the Division of Chemistry & the Law. Sarah P. Hasford, chair of the division, tells C&EN that it is a policy of the division not to comment on any pending litigation matters.
Dookhan pleaded not guilty in Boston Municipal Court on Sept. 28 and was released on a $10,000 bail. E-mails and phone calls to Dookhan have not been answered. Another hearing is scheduled for Dec. 3.
