Don LaVae Williams Jr., 34, was shot and killed in the early morning hours of Mother’s Day, May 8, 2016, in Southeast Washington, D.C. Police responded to gunfire at about 1:47 a.m. in the 2900 block of Nelson Place SE, near Nelson Place and Fairlawn Avenue SE. Williams, from Waldorf, Maryland, was found with gunshot wounds and died at a local hospital.

Investigators initially had no suspects and sought public help. The case remained unsolved publicly for nearly two years until March 6, 2018, when the Metropolitan Police Department arrested 35-year-old Andrew McKinney of Landover, Maryland, charging him with first-degree murder while armed in connection with Williams’s death.

Are there details about Williams’s last hours or the shooting that anyone in the area remembers and hasn’t shared with investigators?
