Four Dorchester men were charged with a raft of offenses yesterday after an attempted car stop by Boston Police turned into a chase that led to the recovery of an unregistered handgun and a stolen bullet-resistant vest, Suffolk County District Attorney Daniel F. Conley said.

TYRONNE SEAMS (D.O.B. 3/6/86), JONATHAN E. BROWN (D.O.B. 10/14/90), FRED C. PALMER (D.O.B. 2/21/90), and RICARDO D. FIELDS (D.O.B. 10/8/81), all of Dorchester, were arraigned in the Boston Municipal Court on charges of unlawful possession of a firearm, unlawful possession of ammunition, carrying a loaded firearm, and possession of a firearm with an obliterated serial number.

Seams was additionally charged with using body armor during the commission of a felony and receiving stolen property. Fields was additionally charged with possession of a Class D drug with intent to distribute, reckless operation of a motor vehicle, and the civil offense of not having a valid inspection sticker.

Assistant District Attorney Nicole Rimar of Conley’s Gun Prosecution Task Force requested that Fields be held on $150,000 cash bail, that Seams and Palmer each be held on $100,000 cash bail, and that Brown be held on $50,000. District Court Judge Annette Forde ordered Seams, Palmer and Fields held on $25,000 cash bail each and Brown held on $15,000.

Rimar said that, at about 11:00 on Wednesday night, Boston Police officers responded the area of the Lenox Street Housing Development after receiving intelligence that associates of a Washington Street gang were in rival gang territory. While patrolling the area, officers observed a black Acura Legend with tinted windows at the intersection of Hammond and Tremont streets. Officers queried the license plate and found that the car did not have a valid inspection sticker.

When the officers activated their lights and siren to stop the vehicle, the driver – later identified as Palmer – began accelerating at a high rate of speed, leading officers through a chase in the area of Whittier and Ruggles streets.

During this pursuit, the officers observed the vehicle’s occupants open the rear passenger side door and drop a metallic object onto the street. The car was travelling so rapidly that the object – later revealed to be a gun – sent sparks flying as it skidded across the pavement. Officers later recovered the .38 caliber Taurus Special firearm with an obliterated serial number and five rounds of ammunition.

Shortly after the firearm was dropped from the vehicle, officers watched as two men jumped from the moving vehicle. Palmer allegedly exited from the driver’s seat, leaving the car to cruise driverless into another vehicle, while Brown from the left passenger’s side. Officers pursued both men on foot and apprehended them while another officer approached the car’s resting place on Dewitt Drive.

Fields and Seams were identified as the two remaining men in the car. Officers ordered them out of the vehicle. Both men allegedly refused to comply with the orders and had to be removed from the vehicle by several officers.

After taking the four defendants into custody, officers recovered two plastic bags of marijuana from Palmer’s person. Officers also removed body armor that Seams had been wearing under his clothes. Officers determined that Seams was not the rightful owner of that body armor and that it had been stolen.

“My probation officer told me I should wear one for protection,” he allegedly told police after being read his Miranda rights.

Palmer is represented by attorney Lisa Grant, Brown by John Russell, Seams by Paul Derby, and Fields by Steven Sack. They are all expected to return to court on Sept. 13.
