At about 9:36 PM on Tuesday, July 29, 2014, officers from District C-11 (Dorchester) responded to radio calls for shots fired and a “shot-spotter” activation in the area of Topliff and Speedwell Streets in Dorchester.
Upon arrival, officers recovered ballistic evidence at the above location and observed ballistic damage to parked cars and a nearby residence. Officers made contact with the building manager and resident of that home, who allowed the officers to make a protective sweep of the units to ensure there were no victims inside. During a sweep of the common areas, officers recovered a Peerless 12-gauge, sawed-off shotgun from a duffel bag on the rear porch of a unit.
As a result of the above radio calls, members of the Youth Violence Strike Force assumed directed patrol in the area of Geneva Avenue and Bowdoin Street. As officers received information from the 911 dispatcher that persons involved in the above incident may be walking in the area of Levant Street, they observed two individuals walking from Levant onto Geneva. Officers engaged the two males in conversation, and one male immediately made defensive statements and actions. Due to the close proximity and recency of the “shot-spotter” activation, calls for shots fired, the recovery of ballistics, and the statements of the individuals, officers performed a pat frisk of the males for their safety. During the frisk, officers recovered a loaded Norinco .45 caliber automatic firearm from the waistband of one of the males.
Officers arrested 18-year-old Gelson Barbosa of Dorchester, and charged him with Unlawful Possession of a Firearm, Unlawful Possession of Ammunition, and Carrying a Loaded Firearm.
