ONE LESS GUN: At about 6:40PM, on Thursday, July 19, 2018, detectives assigned to District B-2 (Roxbury) arrested two individuals for firearms violations in the area of Washington Street and Croftland Avenue in Dorchester.
As part of an ongoing investigation, detectives had been granted an arrest warrant for the person of 19-year-old Tyrece Tennyson-Young of Dorchester, as well as, a search warrant for his residence in the area of Washington Street in Dorchester. While en route to serve the warrants, detectives observed Tennyson-Young riding a bicycle alongside 19-year-old Deshawn Grayson of Mattapan, who was also riding a bicycle. The detectives stopped their unmarked cruiser and, with badges prominently displayed, attempted to stop Tennyson-Young to place him under arrest. However, Tennyson-Young maneuvered his bike away from the detectives in an attempt to flee. After a brief struggle, detectives were able to stop him and place him into handcuffs. During a search of Tennyson-Young, the detectives recovered a loaded .38 caliber Smith & Wesson revolver (see photo below) with obliterated serial numbers.
Meanwhile, another detective continued to follow and monitor Grayson from his cruiser. While the detectives arrested Tennyson-Young, Grayson continued riding his bike away from the scene. As Grayson rode, the detective observed that he held one hand on the handlebar and the other arm pinned tightly against his waist, causing him to lose control of the bike and fall off. Grayson then fled on foot, continuing to move his left arm freely in a running motion while his right arm remained pinned against his side and waistband. From his past training and experience, the detective knew this action was consistent with that of a suspect who may be unlawfully carrying a firearm, particularly when unholstered in his waistband. The detective pursued Grayson in his cruiser until he reached the rear of 7 Croftland Avenue where he exited his cruiser and observed Grayson jump over a wooden fence before the detective lost sight of him. The detective requested additional responding units to set up a perimeter in order to locate Grayson. While canvassing the area, the detective observed a pair of shoes and a white sock that appeared to contain a solid object consistent with the shape of a firearm. The detective recovered the shoes and the sock, which contained a loaded .380 caliber firearm. Shortly after finding the evidence, detectives located Grayson, shoeless, hiding behind a shed.
Detectives have charged both Tennyson-Young and Grayson with Unlawful Possession of a Firearm, Unlawful Possession of Ammunition, and Unlawfully Carrying a Loaded Firearm. Tennyson-Young will also be charged with Destruction/Injury of Personal Property by virtue of the outstanding warrant and Possession of a Firearm with Obliterated Serial Number. Grayson will additionally be charged with Resisting Arrest and Trespassing. Both will be arraigned in Dorchester District Court.
