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

Baltimore, Maryland – U.S. District Judge Brendan A. Hurson today sentenced Marvin Benjamin Sparrow, age 32, of Baltimore, Maryland, to ten years in federal prison, followed by three years of supervised release, for an armed commercial robbery of a T-Mobile store in Baltimore County, Maryland. 

The sentence was announced by Erek L. Barron, U.S. Attorney for the District of Maryland; Special Agent in Charge Special Agent in Charge Toni M. Crosby of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Baltimore Field Division; Chief Gregory Der of the Howard County Police Department; Chief Amal E. Awad of the Anne Arundel County Police Department; and Chief Robert McCullough of the Baltimore County Police Department; and Commissioner Richard Worley of the Baltimore Police Department.

According to his guilty plea, in January 2020, Sparrow and his co-conspirators planned and committed armed robberies of three businesses located in Howard, Anne Arundel, and Baltimore Counties.  Specifically, Sparrow participated in the January 22, 2020 armed robbery of a T-Mobile store located in Dundalk, Maryland.  During the robbery, Sparrow’s co-conspirator brandished a gun, and then Sparrow and the co-conspirator stole cellphones and other electronic devices.  After the robbery, Sparrow and two co-conspirators were apprehended and arrested by law enforcement officers. 

This case is part of Project Safe Neighborhoods (“PSN”), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.

U.S. Attorney Barron commended the ATF, the Howard County Police Department, the Anne Arundel Police Department, the Baltimore County Police Department, and the Baltimore Police Department for their work in the investigation.  Mr. Barron thanked Assistant U.S. Attorneys John W. Sippel, Jr., and Adey Adenrele, who prosecuted the case.
