From 4th District Commander Kimberly Chisley-Missouri:
Around 11:30 pm, units were summoned to the 5900 blk of Ga Ave for sounds of gunshots. 3 juvenile shooting victims were located and transported to area hospitals. Detectives are on the scene investigating.
And later, from Captain Francis Hill:
Despite the best efforts of the medical staff, one of the individuals who was shot could not be saved and has succumbed to his injuries. This is still an open case, and anyone with any information is asked to call the Homicide Branch on 202-645-9600.
And from the WP:
Investigators said early Saturday that the shooting apparently followed a go-go concert on Georgia Avenue at which fights broke out.
