On the morning of Thursday, July 18, 2024, 29-year-old Lamont Street was killed in a mass shooting in Southeast Washington, D.C. The attack occurred at about 11:20 a.m. in the 2200 block of Alabama Avenue, where multiple suspects reportedly exited a vehicle and opened fire. Street was one of two people who died; 50-year-old Jermaine Proctor was also killed. An adult male and a two-year-old girl—who was with a daycare class walking to a playground—were wounded but survived with non-life-threatening injuries.

The Metropolitan Police Department’s preliminary investigation links the attack to an ongoing conflict between rival neighborhood groups, and prosecutors described the shooting as part of a consistent, well-planned campaign of violence involving individuals connected to Henson Ridge and Alabama Avenue. What additional information do readers in the area have about that neighborhood conflict or the morning of July 18?
