Hollis Bradford Johnson, 36, was fatally shot late on October 27, 2014, inside the entryway of his apartment building on the 1000 block of Chillum Road in Chillum, Maryland. Officers were dispatched at about 11:20 p.m. after a neighbor reported a shooting; Johnson was found with a gunshot wound near the entrance, taken to a hospital and died shortly afterward (some records and obituaries list October 28 as his date of death). Earlier that evening he had been watching Monday Night Football at a bar in Northwest Washington, D.C., and family say he was on the phone with a friend as he entered the building when the call abruptly changed and sounds of a disturbance were heard.

Surveillance footage obtained by investigators shows a man approaching the secured building as Johnson entered; Johnson appears to hold the exterior door open, the man fires at him inside the entryway, then runs back out and flees in a light-colored four-door sedan with tinted windows and halogen headlights. Detectives said they did not believe the two men knew each other, and no motive has been publicly established. A reward was offered and police released the footage, but no arrest, charge or public identification of a suspect had been reported, and the case remains unsolved.

Did anyone in the Chillum neighborhood at that time see the sedan or the man captured on surveillance?
