Montgomery County Man Sentenced for a Spree of 10 Armed Robberies During a Four-Week Period

Per the United State’s Attorney’s Office: “Quaysa Flumo, 35, of Washington, D.C., was sentenced today to 234 months in prison and Emmanuel Sumo, 29, of Takoma Park, Md., was sentenced to 214 months for a string of armed robberies that struck a series of gas stations, liquor stores, convenience stores, and restaurants in the Washington, D.C. metropolitan area, all within a four-week period in 2018.

According to the government’s evidence, Flumo and Sumo were members of a trio – which included Enyinna “Reggie” Onyewu, 31, of Silver Spring, Md. – and were found guilty by a jury in U.S. District Court on March 28, 2022, of federal conspiracy, robbery, and (for Flumo and Sumo) related weapons charges. The government’s evidence showed that Onyewu took part in five of the robberies; Sumo in seven of the robberies; and Flumo in all 10 of the robberies.

Throughout January 2018, the defendants, working together, robbed a series of gas stations, liquor stores, convenience stores, and restaurants in the Washington, D.C. metropolitan area. In each of the robberies, the defendants were armed with a .45 caliber handgun. They wore masks and gloves to avoid being identified. During several robberies, they physically assaulted store employees and put the gun directly to the heads of their victims. The robberies took place at various hours, including some in broad daylight. The victims were left shaken and shocked by the incidents. Fortunately, none of them sustained serious physical injuries.

At trial, the government presented testimony from nearly 30 witnesses. The first robbery took place on Jan. 2, 2018, at a gas station in Silver Spring. Other targets were in Takoma Park, Md., Silver Spring, Md., Northwest Washington, and Arlington, Va. On Jan. 10, 2018, two robberies took place within a 45-minute period. The final robbery in the series took place on Jan. 29, 2018, at another gas station in Silver Spring.

Onyewu was arrested on Oct. 22, 2020; Sumo on Nov. 23, 2020, and Flumo on Apr. 27, 2021. Onyewu was sentenced Aug. 18, 2023, to 166 months in federal prison and 36 months of supervised release by U.S. District Judge James E. Boasberg.  Flumo and Sumo were sentenced today by U.S. District Judge Amit Mehta who also ordered three years of supervised release for each defendant.

In announcing the verdicts, U.S. Attorney Graves, Special Agent in Charge Jacobs, Chief Jones, and Chief DeVaul commended the work of those who investigated the case from the FBI’s Washington Field Office’s Violent Crime Task Force, the Montgomery Co. Police Department, the Takoma Park Police Department, the Metropolitan Police Department, the Prince George’s Co. Police Department, and the Arlington County Police Department.

They also expressed appreciation for the efforts of those who worked on the case from the U.S. Attorney’s Office, including Assistant U.S. Attorney Daniel Lenerz, Paralegal Specialists Candace Battle, Mary Downing, and Kim Hall, Legal Assistant Latoya Wade, Supervisory Litigation Technology Specialist Leif Hickling, and Litigation Technology Specialist William Henderson.

Finally, they commended the work of Assistant U.S. Attorneys Nihar Mohanty and Candice Wong of the Violence Reduction and Trafficking Offenses Section (VRTO), who investigated and prosecuted the case.”
