A celebration in Northeast Washington, D.C. ended in gunfire on the evening of March 20, 2021. Twenty-one-year-old Demetris Johnson was at a gender reveal party in the unit block of Madison Street, Northeast, when shots rang out around 7:44 p.m. Officers from the Fourth District found two men who had been shot; Johnson was pronounced dead at the scene and a second victim was taken to hospital with non-life-threatening injuries.

Police identified 18-year-old Nyjell Outler of Southeast, D.C., as the person seen in security footage arriving at the party in a heavy winter coat with a backpack, removing a handgun from the pack, concealing it in his pants, and firing at least four shots into a group that included Johnson before fleeing. A warrant charging him with second-degree murder while armed was issued.

The suspect remained at large for months and was added to a most-wanted list prior to being captured out of state. What details about the night or the people present could help clarify what happened?
