UPDATE 10/10/2023: On October 7, 2024, at approximately 1:00 p.m., Maryland State Police responded to a report that a man had been struck by a vehicle at Spring Valley Drive and Valley Court in Lexington Park. The pedestrian was identified as 53-year-old Demeatrum Scarborough, also known as “Felly,” sustained critical injuries. The driver of the vehicle, a white 2000 Chevrolet Suburban, was identified as 50-year-old Simone Marie Stewart, also known as “Pebbles,” of Lexington Park.

According to witness statements, Stewart and Scarborough had been in a long-term romantic relationship that had recently become strained. Stewart’s daughter provided key testimony, indicating that on the day of the incident, Stewart and Scarborough had picked up Stewart’s 13-year-old granddaughter for lunch to celebrate the child’s academic achievements.

During the car ride back, an argument ensued between Stewart and Scarborough. Stewart’s daughter stated that this argument escalated into a physical altercation inside the vehicle, with Stewart reportedly striking Scarborough while he was seated in the driver’s seat.

At some point, Scarborough exited the vehicle, seemingly to retrieve his belongings from the back seat. According to Stewart’s daughter, Stewart then moved into the driver’s seat, reversed the vehicle, and struck Scarborough, dragging him underneath the Suburban. Witnesses reported that Stewart continued to accelerate even after Scarborough was lying motionless on the ground.
