Mark Donnell Mosley, 33, was found dead on the street in Washington, D.C., on the night of February 24, 2019. Officers answered reports of a shooting at about 10:05 p.m. on the 600 block of 46th Place Southeast and discovered Mosley with multiple gunshot wounds; emergency medical personnel pronounced him dead at the scene.

Surveillance video showed Mosley walking, stopping, and raising his hands before three men approached; one appeared to carry a dark object resembling a handgun. Detectives treated the incident as a robbery that turned deadly. On April 4, 2019, authorities arrested 23-year-old Roscoe Jones of Temple Hills, Maryland, and charged him with First Degree Murder While Armed. At court, a detective and a witness identified Jones as the man who first approached Mosley holding the object; the witness also said Jones and two others took Mosley’s jacket after an argument.

The defense disputed the prosecution’s theory, saying the key witness planned to recant and arguing that surveillance gaps and other possible suspects were not fully pursued. Did anyone see Mosley that night or have information about the three men seen on video?
