Stephan Rosser-Stewart, Armed Robbery, Massachusetts 2019

BOSTON – A brazen armed robbery at a T-Mobile store in Brockton has ended in a guilty plea for one of the perpetrators. Stephan Rosser-Stewart, 31, pleaded guilty today in federal court in Boston in connection with the January 2019 robbery of the T-Mobile store in Brockton and shooting at police officers as he and his co-defendants fled the scene.

Rosser-Stewart, a Boston man, pleaded guilty to interference with commerce by robbery; conspiracy to interfere with commerce by robbery; discharging, brandishing, using and carrying a firearm during the commission of a crime of violence; and being a felon in possession of firearms and ammunition. U.S. District Court Judge Allison D. Burroughs scheduled sentencing for July 20, 2022.

On the evening of Jan. 26, 2019, Rosser-Stewart, along with co-defendants Darius Carter and Dennis Martin, entered a T-Mobile store in Brockton. The men were carrying semi-automatic firearms, which they pointed at the store manager as they demanded cash and electronics. Darius Carter struck the store manager in the head with a firearm. The men stole approximately $25,000 in cash and electronics and then fled in a vehicle driven by Diovanni Carter.

Police responded, located the getaway vehicle, and a high-speed chase ensued, reaching over 70 mph in residential neighborhoods. During the chase, Diovanni Carter ordered the other men in the car to fire at pursuing police cruisers. Rosser-Stewart and Darius Carter fired a total of eight rounds at the pursuing police cruisers. Law enforcement apprehended Rosser-Stewart, Darius Carter, and Dennis Martin and recovered the stolen phones, cash, and the three firearms used in robbery. Diovanni Carter fled the scene when the car was stopped and was apprehended in March 2019.

Rosser-Stewart, Darius Carter, Diovanni Carter, and Dennis Martin, were each prohibited from possessing firearms and ammunition due to prior criminal convictions. Rosser-Stewart was previously convicted of armed robbery in Suffolk Superior Court and had been recently released from prison prior to robbing the T-Mobile store in January 2019.

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 up to 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 up to 10 years for the discharge of a firearm.
