On the evening of June 19, 2019, gunfire on the 700 block of Princeton Place NW in Washington, D.C., left 29-year-old Juan Marcell Grant dead. Police responded around 9:24 p.m.; Grant, a Northwest D.C. resident, was found with multiple gunshot wounds and later died at a hospital.

Investigators later developed a suspect. On August 16, 2019, the Capital Area Regional Fugitive Task Force arrested 19-year-old Keandre Barber of Suitland, Maryland, on a D.C. Superior Court warrant and charged him with first-degree murder while armed in connection with Grant’s death. In September 2019 a judge found probable cause to proceed after prosecutors showed alley video they said placed Barber and another individual with Grant. The judge initially ordered Barber held without bail; in October 2019 a judge released him on GPS monitoring with a stay-away order from Grant’s family and directions to avoid Washington, D.C., except for court and lawyer meetings.
