Subsequently, Mr. Soares was placed under arrest for Possession of a Class B Substance (Oxycodone) with the Intent to Distribute. He was arraigned in the Falmouth District Court and released on personal recognizance.

Later that afternoon, task force officers and members of the Martha’s Vineyard Tactical Response Team (MVLEC) executed a search warrant at an Ocean Heights, Edgartown (Martha’s Vineyard) residence where Mroczkoski resides.

As a result of the search, officers located and seized 353 rounds of various caliber ammunition, approximately 3.5 grams of cocaine, 60 Amphetamine pills, a quantity of unknown pills, and a large capacity (30 rounds) firearm feeding device.
