Gun purchased in NH allegedly used to shoot Boston police officer

WARNER – A gun used to shoot a Boston police officer in January was bought by a New Hamsphire woman whom police believe was supplying them to gang members in Boston, according to an affidavit unsealed Friday.

The Glock 27 that wound up in the hands of Grant Headley is one of an estimated 30 to 63 firearms purchased by Sara Johnson of Manchester, according to authorities.

“At least four of the firearms purchased by Johnson were subsequently recovered on the streets of Greater Boston within seven months, and in some cases less time than that, of Johnson purchasing them,” Daniel P. McPartlin, a special agent with the Bureau of Alcohol, Tobacco and Firearms said in a sworn affidavit filed in U.S. District Court.

Headley allegedly shot Boston police Officer Kurt Stokinger in the leg on the morning of Jan. 8 in Dorchester, Mass. The Glock was recovered at the scene of the shooting, according to McPartlin’s affidavit.

Investigators say Johnson purchased the handgun from a Claremont firearms dealer that was offering it for sale online. The two met up at a McDonald’s restaurant in Warner last July 25 after Johnson contacted him.

Johnson is currently not facing charges, but the investigation into her alleged gun running is tied to the recent roundup of nearly 60 gang members in Boston on June 9. According to The Boston Globe, the gangs - the 18th Street Gang, the East Side Money Gang, the Boylston Gang, and the Orient Heights Gang - have a heavy presence in East Boston, Brockton, Chelsea, and Everett areas.

The four firearms allegedly recovered in Boston and traced back to Johnson had their serial numbers obliterated, and three of them were later purchased by confidential informants working with the ATF, according to the affidavit.

Johnson, who worked as a legal assistant in a New Hampshire law firm, came under scrutiny during an ATF investigation involving firearms and gang activity in the Chelsea, Mass. area.

McPartlin traced guns that were bought by confidential informants back to purchases that Johnson made, the affidavit suggests. Johnson repeatedly met up with men offering guns for sale online outside of stores, including locations in Epping and Londonderry.

Not everyone was willing to sell Johnson a gun after meeting her.

Federal agents interviewed a Londonderry man who told them that Johnson backed out of a deal to buy his Glock handgun when he suggested that they go a nearby federally license firearms dealer to complete the transaction. The man met Johnson outside of a 7-11 store in Londonderry to carry out the transaction, but the man noticed that Johnson wasn’t alone. Another man had accompanied her, according to McPartlin.

“(He) stated that he became nervous that it might be a ‘straw purchase’ scenario,” McPartlin said in the affidavit.
