Defendant, Aiming Elsewhere, Hit Motorist in Northeast Washington

            WASHINGTON – Barry Marable, 26, of Washington, D.C., was sentenced today to 14 years in prison for firing a gun in a busy area of Northeast Washington and fatally wounding a 22-year-old man whose car was stopped at a traffic light.

            The announcement was made by U.S. Attorney Matthew M. Graves and Robert J. Contee III, Chief of the Metropolitan Police Department (MPD).

            Marable pleaded guilty on Nov. 19, 2021, in the Superior Court of the District of Columbia, to a charge of voluntary manslaughter while armed. He was sentenced by the Honorable Neal E. Kravitz. Following his prison term, Marable will be placed on five years of supervised release.

            According to the government’s evidence, on Oct 24, 2018, just before 6 p.m., the victim, Roger Thomson Marmet, known as Tom to his family and friends, was driving home from a job with the non-profit So Others Might Eat (SOME). Mr. Marmet was driving down 17th Street NE and stopped for a light at 17th and Bladensburg Road NE.

            Marable, meanwhile, was in the same area. He saw a man at a nearby gas station who he believed had assaulted him about one week earlier. Marable removed a firearm from his pocket and pointed it towards the gas station. He fired four times from an alley – with two sidewalks and four lanes of traffic between him and the other man, who was unarmed. One of these shots struck Mr. Marmet, who died less than an hour later. No one else was hit by the gunfire.

            Marable was arrested on Dec. 28, 2018. He has been in custody ever since.

            In announcing the sentence, U.S. Attorney Graves and Chief Contee commended the work of those who investigated the case from the Metropolitan Police Department. They also expressed appreciation for the work of those who handled the case at the U.S. Attorney’s Office, including Deputy Chief Sharon Donovan, of the Office’s Homicide Section, Victim/Witness Advocate Jennifer Clark, and Paralegal Specialist Stephanie Gilbert, Finally, they commended the efforts of Assistant U.S. Attorneys Kimberley C. Nielsen and Gauri Gopal, who investigated and prosecuted the case.
