Christopher Popi Brown, 17, was killed during a mass shooting at an unauthorized block party in the 3300 block of Dubois Place Southeast, Washington, D.C., on August 9, 2020. The event had swelled after being advertised on social media. At about 12:20 a.m. a dispute escalated and at least three people opened fire, discharging more than 100 rounds into the crowd. Twenty-two people were shot; two others were injured while fleeing. Christopher Brown was pronounced dead at the scene and was the only fatality. An off-duty police officer was among the critically injured.

Brown was a father and his partner was expecting another child. The Metropolitan Police Department opened a homicide investigation, working with the FBI and ATF, and a reward has been offered for information leading to arrest and conviction. Despite numerous witnesses and a large-scale probe, no arrests have been announced and the shooters remain at large.

Did anyone at the block party or nearby that night see anything that could identify those who opened fire?
