For Immediate Release
U.S. Attorney's Office, District of Massachusetts

BOSTON – A Boston man was convicted yesterday by a federal jury in relation to an armed robbery of a T-Mobile store in Brockton, where multiple gunshots were fired at Brockton Police Officers during a high-speed chase.

A jury convicted Diovanni Carter, 30, of Boston, yesterday of conspiracy to commit a robbery affecting interstate commerce, robbery affecting interstate commerce, and use and carrying, brandishing and discharge of a firearm during and in relation to the robbery. U.S. District Court Judge Allison Burroughs scheduled sentencing for July 7, 2020.

According to the trial testimony, on Jan. 26, 2019, Diovanni Carter orchestrated a plan with three other men to rob a T-Mobile store in Brockton.  Diovanni Carter drove the group from Boston to Brockton.  When they arrived, the three men went into the store carrying semi-automatic firearms that they pointed at the store manager, demanding cash and electronics, while Diovanni Carter waited in the getaway vehicle.  During the robbery, the store manager was struck in the head with the firearm.  The three men stole approximately $25,000 in cash and electronics, left the store, and entered the getaway vehicle driven by Diovanni Carter.

Brockton Police responded and located the getaway vehicle.  A high speed chase ensued through residential neighborhoods reaching speeds of over 70 mph.  During the chase, Diovanni Carter ordered the other men in the car to fire their weapons at the pursuing police cruisers as part of their effort to escape. In total, at least eight rounds were fired at the police.  The suspects then abandoned the car nearby and ran on foot.

During the search by law enforcement, the stolen phones and cash and the three firearms used in robbery were recovered.  Darius Carter, Stephan Rosser-Steward and a third man were apprehended shortly after the robbery.  They were wearing clothes consistent with those worn in store video surveillance.  Diovanni Carter was not apprehended that night.

Through the investigation, a warrant was obtained for Diovanni Carter’s arrest, and he remained a fugitive from state charges until March 5, 2019, when he was apprehended.  

The charge of interference with commerce by robbery provides for a sentence of up to 20 years in prison, five years of supervised release and a fine of up to $ 250,000. The charge of being a felon in possession of ammunition provides for a sentence of no greater than 10 years in prison, three years of supervised release and a fine of up to $250,000.  The charge of use of a firearm during the commission of a crime of violence provides for a sentence of up to life in prison, and a mandatory consecutive term of imprisonment ranging from: five years for the possession of a firearm, seven years for the brandishing of a firearm and 10 years for the discharge of a firearm. Sentences are imposed by a federal district court judge based on the U.S. Sentencing Guidelines and other statutory factors.
