Shortly after 1:00 a.m. on August 5, 2023, a burst of gunfire on the 2500 block of Ontario Road Northwest in Adams Morgan killed 34-year-old James Morgan of Southeast, D.C., his 30-year-old brother Jamal Morgan, and later 42-year-old Vincent Martin. Police found the three men with gunshot wounds; James and Jamal were pronounced dead at the scene and Martin died at a hospital two days later. An autopsy found James had sustained nine gunshot wounds.

Investigators say an altercation occurred before the shooting and that the victims initially walked away; prosecutors allege the two suspects followed and opened fire. Two men were arrested on December 5, 2023: 37-year-old Renza Bryant of Northwest, D.C., and 34-year-old Jalonte Thompkins of Northeast, D.C., each charged with first-degree murder while armed. Thompkins has pleaded not guilty to three counts of first-degree murder.
