A former employee with the Massachusetts Department of Environmental Protection has been accused of smuggling K2-laced papers to a federal inmate.

Bridgewater woman Tasha Hammock, 43, is being charged with providing contraband to FMC Devens inmate Raymond Gaines, 45 — who had been granted clemency by President Joe Biden in the final days of his term in January.

Gaines, whose 2022 federal prison sentence for drug distribution had been cut, has now been indicted by a federal grand jury with possessing contraband by a prison inmate.

K2, a synthetic cannabinoid, has been a reported health problem at FMC Devens and other facilities. Inmates have become sick from smoking paper believed to contain K2, as well as prison staff who have been exposed to the secondary smoke.

Hammock was a program coordinator with MassDEP, where she took home more than $84,000 in 2023, according to state payroll records.

According to the feds, Hammock was visiting Gaines in the prison last Aug. 18 when she “surreptitiously passed K2-laced papers to Gaines, which he pocketed.”

Hammock also allegedly previously handled money connected with the distribution of K2 to Gaines in FMC Devens, and she allegedly received K2 at her residence for distribution into the prison.

Court records allege that law enforcement obtained a phone that had been smuggled to an inmate in the prison (“Inmate A”).

In September 2023, Inmate A allegedly sent messages on the cell phone to another person (“Person 1”), discussing obtaining K2 in prison.

Inmate A allegedly told Person 1 that the drugs could be delivered to a particular address in Bridgewater — later determined to be Hammock’s residence — and that Inmate A’s “co” would arrange for the drugs to be brought into the prison from there.
