Marcus Wallace, 36, was shot and killed on November 21, 2020, in the 1400 block of L Street Southeast, Washington, D.C. Police and D.C. Fire and Emergency Medical Services responded to reports of gunfire at about 9:05 p.m.; Wallace was found inside a residential building with gunshot wounds and was pronounced dead at the scene.

A suspect was arrested a month later when 21-year-old Antonio Deshaun Gladden of Southeast, D.C., was taken into custody on December 23, 2020, and charged with first-degree murder while armed. Those charges were subsequently dismissed, and Marcus Wallace’s murder remained officially unresolved.

Wallace’s death is alleged to have precipitated further violence. On January 19, 2021, 34-year-old Tyrone Wright was shot and killed in what authorities described as a revenge killing; investigators later alleged that Marcus’s brother Ronald Wallace, 48, and cousin Deangelo Glover, 30, targeted Wright believing him responsible for Marcus’s murder. Does anyone have information about Marcus Wallace, his circle, or the events leading up to November 21, 2020?
