Marcus J. McClam, 29, was found fatally shot inside an apartment in the 1200 block of Brentwood Road NE in Washington, D.C., after police responded to reports of gunfire on February 23, 2015, around 12:30 a.m. Officers recovered five shell casings in a rear area of the building and forced entry to the apartment, where McClam was located with multiple gunshot wounds to his chest and armpit; he was pronounced dead at the scene.

He was originally from Upper Marlboro. A reward of up to $25,000 has been offered for information leading to an arrest and conviction.

Can anyone with knowledge of Marcus, his movements that night, or the Brentwood Road area around that time help investigators?
