A dispute over alleged property theft ended in a fatal shooting in Southeast Washington, D.C. On Wednesday, February 10, 2016, 23-year-old Mauricio Dannell Walker was shot and killed in the 1900 block of 18th Street SE. Earlier that afternoon Walker and another person were seen checking for unlocked car doors near the 2100 block of R Street SE. A resident, Alphonso Roberts, confronted a second individual who was taking items from his Volvo; Walker and the companion walked away.

Moments later, as Walker and the other person crossed a grassy area near the Anacostia Library in the 1800 block of Good Hope Road SE, Roberts drove up in his Volvo, exited with a handgun, and fired. Walker was struck in the back and head while trying to flee, collapsed, and was later pronounced dead. The Metropolitan Police Department identified Roberts as the suspected shooter and arrested him; he later pleaded guilty to second-degree murder while armed as part of a plea that included a federal firearms count.

Does anyone have information about Walker’s movements that afternoon or recall seeing the Volvo in the area?
