On the afternoon of Thursday, May 9, 2019, gunfire on a residential block in the Washington Highlands neighborhood of Southeast Washington ended the life of 28-year-old Mark Steven Milline Jr. Officers responding to reports of possible gunshots found Milline on a sidewalk near the 800 block of Xenia Street SE, by the Ferebee Hope Recreation Center, with multiple gunshot wounds. He was taken to a nearby hospital and later pronounced dead.

The Metropolitan Police Department recovered surveillance footage that showed three individuals and a vehicle of interest; the vehicle was later recovered but the three people seen on video have not been identified. A reward of up to $25,000 was offered for information leading to an arrest and conviction, yet no arrests have been announced and the case remains unsolved.

If anyone saw the shooting, the people in the surveillance footage, or has information that could help identify those involved, please come forward to assist the investigation.
