Brookline man was hauling a small armory of guns and ammo on a trip back from New Hampshire, State Police say

State Police report troopers responding to calls about an erratic driver on I-95 south Saturday night wound up arresting a Brookline man on a variety of gun and drug charges.

A trooper dispatched to find the erratic driver did not have much trouble finding Stewart Silvestri, 24, because, as callers had reported, he had pulled into a deserted truck weighing station in Rowley around 10:35 p.m., State Police say.

Trooper [Charles] Buckley spoke to the operator and lone occupant, STEWART SILVESTRI, 24, of Brookline. While interacting with SILVESTRI, the Trooper observed a handgun with a 50-round drum magazine in plain sight inside the vehicle. The Trooper then observed another handgun under the driver’s seat. At that time, Trooper Buckley removed SILVESTRI from the vehicle and secured him for reasons of officer safety while continuing his investigation. Other MSP personnel began responding to assist.

State Police say troopers found seven handguns and one AR-style short-barreled rifle" inside his Outlander, as well as 34 magazines, 23 of which were high capacity magazines. State Police add that 23 of the magazines were already loaded with ammo.

Also located in the vehicle were at least 22 various firearm components and hundreds of rounds of ammunition.

Silvestri does not have a Massachusetts firearms license, State Police say, adding they believe he bought all the guns and ammo and parts in New Hampshire.

While awaiting booking at the Newbury barracks on a raft of gun charges, State Police continue, Buckley determined that Silvestri seemed like he might have been driving while under the influence of something and administered several field sobriety tests that led to an OUI-Drugs charge.

But wait, there's more:

Inside SILVESTRI’s backpack Troopers located approximately 42 grams of cocaine, 53 suboxone strips, 167 Xanax pills, approximately 15 grams of liquid GHB (a central nervous system depressant), and multiple other types of drugs. Also located in the backpack were several prescription medications. Trooper Buckley determined that SILVESTRI had been operating a motor vehicle under the influence of drugs. Information gathered in the investigation suggests SILVESTRI may have obtained the firearms in New Hampshire.

Silvestri was finally changed with 8 counts of unlawful possession of a firearm, 25 counts of possession of a large capacity weapon or feeding device, multiple counts of possession of a large-capacity firearm in commission of a felony and improper storage of a large capacity firearm, possession of a silencer and possession of a firearm while under the influence, State Police say. He was also charged with possession of Class A, B and E drugs and OUI-Drugs.

Innocent, etc.
