Alvin Barnes was 19 when he was shot and killed in Southeast Washington on October 23, 2019. Police were called to the 2200 block of Alabama Avenue SE around 12:12 p.m.; Barnes was found with a gunshot wound, taken to a hospital, and pronounced dead.

Investigators say Barnes had been involved in a physical altercation with another person shortly before the shooting. That person drove away from the scene, fired a weapon from the vehicle, and struck Barnes in the back of the head. The shooter was identified as 20-year-old Keith Jenkins, who later turned himself in and pleaded guilty to voluntary manslaughter while armed in connection with Barnes’s death.

Jenkins was sentenced to 11 years in prison, followed by five years of supervised release, and must register as a gun offender. Did anyone in Southeast D.C. see or hear anything around Alabama Avenue SE that afternoon in October 2019?
