On November 14, 2015, 24-year-old Onyekachi Emmanuel Osuchukwu III was shot to death inside a Southeast Washington, D.C., apartment in the 2900 block of 2nd Street SE. He had been visiting from California when he was lured to the apartment by a man described as a long-time friend. The friend confronted Osuchukwu and shot him multiple times, then fled the scene.

Investigators say the killing grew out of a dispute over money from drug dealings. The next day the friend returned to the apartment with relatives and called 911, claiming to have discovered his best friend’s body. An anonymous tip led police to arrest Eugene Burns in December 2015; Burns later told a relative the shooting happened after Osuchukwu charged at him.

What additional details about the hours before November 14 might help explain how this planned meeting turned deadly, and can anyone who knew Osuchukwu or the people involved shed light on his movements that week?
