A grand jury indicted Johnson on a charge of first-degree murder and several assault and weapons offenses last week.
Police found Brown gunned down on a sidewalk in the 1700 block of Galen Street Southeast on July 8, 2012. Charging documents in the case do not make it clear whether Brown was the target of the shooting.
According to the documents, a witness told police that Johnson, 19, approached Brown and another person from behind as they were walking along Galen Street SE. The witness said that Johnson began shooting at Brown’s companion, who then fled into the 2300 block of Green Street Southeast, with Johnson in pursuit.
Police found Brown lying on the sidewalk on Galen Street; he died on the scene from a gunshot wound to the chest. A second victim was found suffering from gunshot wounds in the hallway of an apartment building on Green Street; he was taken to the hospital for treatment.
A status hearing has been scheduled for May 24.
The indictment is below.
