The Montgomery County Department of Police Major Crimes Division has arrested Maurquise Emillo James, 22, in connection with the fatal shooting of Robert Fuller Jr., 87, at Cogir Potomac Senior Living. James, a Baltimore resident and employee at the facility, was arrested on February 24, 2026, and charged with first-degree murder.
The incident occurred on February 14, when officers and Montgomery County Fire and Rescue Service personnel responded to a reported medical emergency and found Fuller unresponsive in his apartment. He was pronounced dead at the scene, and the Office of the Chief Medical Examiner later ruled his death a homicide caused by a gunshot wound.
Investigators reviewed surveillance footage showing a masked individual entering and leaving the building through a propped-open door, with alarms disabled. Additional video and public tips helped identify James.
Police also linked the case to a February 24 traffic stop involving Maryland State Police, during which shots were fired at a trooper. Ballistics evidence suggested the same firearm was used in both incidents. Later that day, James was arrested by Montgomery County officers assigned to the U.S. Marshals Fugitive Task Force in Rockville, after attempting to flee. Search warrants were executed in Baltimore County, and investigators recovered items of potential evidentiary value. James is currently being held at the Montgomery County Central Processing Unit pending a bond hearing.
