At about 6:25 PM on Tuesday, April 30, 2019, officer assigned to District A-15 (Charlestown) responded to the area of One Constitution Road for a person yelling and waving an object in his hand that looked like a magazine to a gun.
The suspect apparently owned a boat in the area and was last seen walking off the dock after leaving threatening notes on a nearby owners boat slip. Officers observed a male matching the suspect’s description and stopped him in the area of 28 Constitution Road. Officers encountered Jeffery Oliveira, 36 of Charlestown, in front of the marina building and asked him if he had any weapons on his person but Oliveira refused to speak to officers. After further investigation it was revealed that Oliveira had placed two bags inside the marina door. Officers searched the bag and recovered a loaded silver and brown Smith & Wesson 9mm pistol, and a loaded black Smith & Wesson .38 special revolver.
Oliveira was placed under arrest for Assault by Means of a Dangerous Weapon (firearm), Unlawful Possession of a Firearm, and Unlawful Possession of ammunition. He will be arraigned in Charlestown District Court.
