Police arrested a D.C. man Thursday in the death last week of a man who was found shot inside a burning apartment in Northwest Washington.

The Capital Area Regional Fugitive Task Force apprehended Jermaine Brown, 34, of Northwest, about 4 p.m. Thursday and authorities charged him with first-degree murder while armed, police officials said in a statement. Authorities allege that Brown is responsible for the killing of Randolph Scott Harris Jr. , 31, who was found early July 26 in an apartment fire in the 1000 block of Euclid Street NW.

Rescuers were called to the apartment just after 6 a.m. that morning for the report of smoke in the building, and had to force their way into unit. They found Harris suffering from burns and gunshot wounds.

Investigators are awaiting the results of an autopsy to determine the cause and manner of Harris’ death, officials said.
