The Massachusetts Department of Health Lab in Jamaica Plain (William A. Hinton Drug Laboratory) was ordered shut down by the governor a few weeks ago when it was discovered that at least one of the chemists at the lab allegedly engaged in malfeasance and violation of protocol with drug samples in criminal cases. The drug lab handled several thousand drug samples seized from criminal drug arrests in multiple counties, including Suffolk County, Middlesex County (until 2009), Bristol County, Worcester County and Norfolk County.
By way of background, when the police seized drugs in criminal cases, the drugs were ultimately sent to the DPH drug lab for testing and confirmation that the substance was, in fact, the certain controlled substance it was thought to be. At the lab, each drug sample was analyzed by one chemist, whose results were then checked by another chemist.
As it turns out, one of the supervising chemists is alleged to have engaged in intentional violation of protocol by tampering with evidence bags; altering the weight of drugs; not calibrating the drug testing machines properly; and even altering drug samples so that they would test as drugs when they were not! This particular chemist, who was employed by the DPH drug lab in Jamaica Plain from 2003 to 2012, is believed to have been involved with as many as 60,000 samples and 182,000 criminal drug cases.
