Officers performed a traffic stop and arrested the operator after confirming his license was suspended. Marshall Hawkins, 53, of Dorchester, was placed in custody without incident at which time they located and recovered a loaded .22 caliber Sterling handgun from inside the vehicle. It was later determined that the firearm had an obliterated serial number. During the booking process, officers recovered a plastic bag containing heroin from the suspect’s pants pocket. The suspect will appear in Roxbury District Court on charges of Unlawful Possession of a Firearm, Unlawful Possession of Ammunition, Possession of a Firearm with an Obliterated Serial Number, Possession of Class A Drugs and Operating a Motor Vehicle After Revocation or Suspension.
