On July 1, 2022, 17-year-old Dennis Simms was shot and killed in a daylight drive-by in the 800 block of Yuma Street in Southeast Washington, D.C. Emergency responders found him with a gunshot wound; he showed no signs of life and was pronounced dead at the scene.

Detectives say their investigation led them to social media, where an Instagram dispute appeared tied to a prior robbery and suggested the shooting was retaliatory. Family members maintain Simms was not the intended target. Court filings and probable cause findings named two brothers in connection with the incident.

In October 2022, 19-year-old Davon Alston of Oxon Hill, Maryland, was arrested and charged with first-degree murder while armed; his 21-year-old brother Juvan Alston was later arrested and charged as well.

If anyone has information about Dennis, the circumstances that led to that day, or the people involved, please come forward to investigators.
